Abstract
The aim of this study was to screen the trypanocidal activity of plants used in traditional Mexican medicine for the treatment of various diseases related to parasitic infections. Cultured Trypanosoma cruzi epimastigotes were incubated for 96h with different concentrations of methanolic extracts obtained from Artemisia mexicana, Castela texana, Cymbopogon citratus, Eryngium heterophyllum, Haematoxylum brasiletto, Lippia graveolens, Marrubium vulgare, Persea americana, Ruta chalepensis and Schinus molle. The inhibitory concentration (IC50) was determined for each extract via a colorimetric method. Among the evaluated species, the methanolic extracts of E. heterophyllum, H. brasiletto, M. vulgare and S. molle exhibited the highest trypanocidal activity, showing percentages of growth inhibition between 88 and 100% at a concentration of 150μg/ml. These medicinal plants may represent a valuable source of new bioactive compounds for the therapeutic treatment of trypanosomiasis.

Abstract
OBJECTIVES We aimed to survey the published literature for articles that describe the use of herbal supplements by elderly patients and to summarize important aspects of selected studies, including most commonly used supplements, study type, study location, and potential hazards of herbal supplement use. METHODS Literature searches were conducted on three scientific/medical databases: Medline, Web of Science, and Scopus. Search results were examined for articles involving the use of herbal products in the elderly population that met selection criteria. RESULTS Initial searches yielded 1297 articles. Of these original results, only 16 met specific selection criteria. Twelve (75%) of studies identified were performed in North America. Nine studies (56.25%) were conducted in the United States. Seven of the studies were cross-sectional (43.8%). The most commonly reported were gingko biloba, garlic, ginseng, aloe vera, chamomile, spearmint, and ginger. Of these, gingko and garlic are the most commonly used among community-dwelling elderly. Both of these supplements have the potential to interact with anticoagulants and produce bruising or bleeding problems. CONCLUSIONS The use of herbal supplements is common among the elderly, a population that takes a disproportionate share of prescription medications compared to that taken by younger populations. Among the problems uncovered by these studies was a lack of dialog between medical professionals and patients about the use of herbal supplements. Prescribers need to consider the use of herbal supplements and discuss the matter with their elderly patients when making decisions about pharmacological treatments.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This study has identified not only the wild plants collected for medical purposes by local people of Elazığ Province in the Eastern Anatolia Region, but also the uses and local names of these plants. These resources are usually regarded as part of a culture׳s traditional knowledge. Therefore, the aim of this study is to collect information from local population concerning the use of medicinal plants of the Elazığ region; identify the most important medicinal plants used; determine the relative importance of the species surveyed and calculate the informant consensus factor (FIC) in relation to medicinal plant use. MATERIALS AND METHODS A field study had been carried out for a period of approximately 2 years (2012-2013). A questionnaire was administered to the local people, through face-to-face interviews (Appendix A). Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. The plant species were collected within the scope of the study; herbarium materials were prepared; and the specimens were entitled. The collected data were used to calculate the FIC and the plant use values. RESULTS 74 Plants were found to be used for medical purposes before in the literature analysis of the plants used in our study, while 6 plants were found to have no literature records. Our results showed that the highest use values were recorded for the species Urtica dioica L. (0.46) and Rosa canina L. (0.42), while the highest FIC was cited for skin diseases (0.60). CONCLUSION Data obtained showed that in the studied area the folk use of plants is alive and still derives from daily practice. Evaluation of pharmacological activity for the promising medicinal plants is suggested.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Indigenous communities have often served as rich repositories of empirical knowledge on medicinal plants used for anemia. Use of these plants need to be validated with respect to their efficacy and safety so as to provide scientific basis of their use. Quantifying presence of medicinal plants used for anemia treatment, validating indigenous knowledge and extent of its use in rural Mkuranga district, Tanzania is the main focus of this paper. METHODS A cross sectional study conducted in May and December 2013 at Mkuranga District of Coastal region of Tanzania. Forty key informants including traditional healers, religious leaders, community members and healthcare workers were interviewed using semi structured questionnaire. Eight focus group discussions were also conducted. Both interviews and focus group discussion gathered data on socio-demographics, general knowledge of anemia and plants used to correct anemia. In a brief field visit, all plants mentioned during the interview were collected and later identified. Both NVivo 10 and STATA softwares were employed for statistical analysis. RESULTS Out of 40 participants, 31 were traditional healers, majority were male (77.4%). Mean age of the participants was 55.7±15 years. About 45% had no any formal education and majority (80%) were married. Twenty eight plant species are used to treat anemia. Hibiscus sabdariffa was the most mentioned species. The species belongs to 24 families, with Euphorbiaceae (14.3%) having the largest number. Lawsonia inermis, Aloe sp, Uvaria acuminata, Parinari curatellifolia, Ozoroa reticulata, Manihot esculenta, Canthium sp and Afzelia quanzensis were the plant species in which their claimed use for anemia were novel. CONCLUSIONS People in rural areas of Mkuranga district possess a rich traditional knowledge of medicinal plants species for anemia treatment. Researches on these plants showed promising anti-anemic activity. Analysis and documentation of this knowledge has not only helped the analysis and recognition of novel information, it also contributed to conserving it for future generations.

Abstract
The term of medicinal plants include a various types of plants used in herbalism with medicinal activities. These plants are
considered as rich resources of ingredients which can be used as complementary and alternative medicines and, also in drug
developments and synthesis. In addition, some plants regarded as valuable origin of nutrition. Thus, all these plants are
recommended as therapeutic agents. Information related to medicinal plants and herbal drugs accumulated over the ages are
scattered and unstructured which make it prudent to develop a curated database for medicinal plants. MPDB 1.0 database is
dedicated to provide the first window to find the plants around Bangladesh claimed to have medicinal and/or nutritive values by
accumulating data from the published literatures. This database contains 406 medicinal plants with their corresponding scientific,
family and local names as well as utilized parts for treatment from different districts of Bangladesh. Information regarding
ailments is available for 353 plants. In addition, we have found active compounds for 78 plants with their corresponding PubMed
ID.

Abstract
This study focused on herbalists, herbal shops and people currently using traditional Arabic medicine. Informants were asked to list plants and methods for obtaining plant herbal extracts used to manage a range of illnesses. A total of 109 plants were identified, of these, principle plant elements included, leaves (47.3%), fruits (18.5%) and seeds (18.0%) were most commonly utilized. Extraction methods included decoction (boiling) 51%, and infusion 17% and prepared as creams, powders, syrups, food or cooked. Many plant species are used by herbalists for treating a range of ailments. This study suggests that a lack of methodological standardization during herbal extraction could compromise herbal stability. There is also a need to monitor for potential adverse drug interactions when used concurrently with prescribed medications.

Abstract
BACKGROUND In South African traditional medicine, some are plants known to combat pediatric diseases and are commonly used by traditional healers. The aim was to evaluate cytotoxicity effects of plants. MATERIALS AND METHODS The ground plant material was exhaustively extracted using methanol, acetone and water separately for 72 hrs. These organic solvents were removed from filtrates using a rotavapour. Stock solutions were prepared at 40 mg/ml Dimethyl sulfoxide (DMSO) and test solutions were transferred into vials and 10 brine shrimps introduced in each. The number of dead shrimps was counted to ascertain toxicity. Ten A. salina nauplii (larva) were transferred into each sample vial and filtered brine solution was added to make 5 ml. The nauplii were counted macroscopically in the stem of the pipette against a lighted background. A drop of dry yeast suspension was added as food to each vial. Probit analysis was used to determine the concentration at which lethality to brine shrimp represents 50 % (LC50). RESULTS All the tested extracts showed that the concentration is directly proportional to death of brine shrimps. Fifty percent lethality (LC50) of the tested crude extract ranged between 4.1 and 4.6 µg/ml with methanol extract of B. abyssinica being the lowest and T. acutiloba the highest. CONCLUSION This study revealed that 100% of plant crude extracts screened for activity against Artemisia salina larvae showed strong cytotoxicity below 10 µg/ml and plant species with LC50 values < 1000 µg/ml may not make good paediatric remedies due to their inherent toxicity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE From ancient time human beings have used different plants, animals and minerals to prevent and treat various diseases. In this respect, plants have been of particular importance. Ethnobotany is the science of reviewing how indigenous people and local tribes have used their regional plants for particular purposes such as treating diseases in the past. The information gathered from such studies can help to improve national health systems and even lead to the discovery of new medicines. Keeping this in mind, in this study a survey of Sirjan area ethnobotany was conducted during 2011-2012. MATERIALS AND METHODS At the beginning, thirteen local people were interviewed about their region׳s medicinal plants and their consumptions. These plants were collected and identified using identification keys. The data collected was analyzed using quantitative value indices FIC, RFC and CI. RESULT Many plants collected have medicinal properties and have been used by local people to treat various ailments. Of these plants, nineteen families, 37 genera and 43 species belonged to medicinal plants. Among them, Lamiaceae with 8 species and Malva L. with 3 species were the largest medicinal plant families and genera, respectively. These plants are often used as decoction (28%) and as powder (21%). Also, the fruit of these plants are used most often. Besides being used as medicinal plants, they have other uses such as food, fuel, etc. Malva sylvestris has the largest value of relative frequency of citation and cultural importance indices. The most ailment categories have the highest level of informant agreement (mean FIC=0.92). CONCLUSION Despite the semi-desert climate and lack of rich vegetation, many medicinal and economic plants are found in Sirjan region. Uncontrolled harvesting of the medicinal plants such as Bunium persicum, Cuminum cyminum, Zataria multiflora and Satureja bachtiarica in this region by local people has increased the risk of their extinction and calls for a restrict control over their protection by the authorities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE African trypanosomiasis is one of the neglected tropical diseases caused by different species of trypanosomes that affect both human and livestock with devastating consequences in the continent. Most of the affected populations commonly use traditional medicinal plants for the treatment of the disease. Consequently, this prompted ethnopharmacological research activities on the anti-trypanosomal activity of a number of these African medicinal plants in order to validate their ethnomedicinal use. Furthermore, such studies could lead to the identification of chemical leads for the development of newer anti-trypanosomal agents from those plants. This review aims to provide updated information on the ethnopharmacological evidence of African medicinal plants with anti-trypanosomal activity. METHODS Literature was collected via electronic search (PubMed, Sciencedirect, Medline and Google Scholar) from published articles that report on the in vitro or in vivo anti-trypanosomal activity of plants that were collected from different parts of Africa. RESULTS African medicinal plants investigated for in vitro and in vivo anti-trypanosomal activity from January 1993 to October 2013 are systematically compiled and all the in vivo studies are critically discussed. A total of 264 plant species belonging to 79 families were investigated for anti-trypanosomal activity. However, only 48 bioactive anti-trypanosomal compounds were successfully isolated in pure forms. Furthermore, some of the plants were investigated for possible ameliorative effects on the trypanosome-induced pathological changes out of which 18 plants were reported to be effective while a few others were not. In spite of interesting preclinical ethnopharmacological evidence for anti-trypanosomal activity, not a single African medicinal plant was investigated in a clinical study. CONCLUSION Several African medicinal plants have demonstrated promising anti-trypanosomal effects but the studies on the anti-trypanosomal potentials of these plants are not taken beyond proof of concept stage. It is hoped that the article would stimulate future clinical studies because of the paucity of knowledge in this area.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The paper presents information about the earliest botanical work from Poland, Warsavia physice illustrata which takes bryophytes into account. It was elaborated by a German physician Christian Heinrich Erndtel and issued in 1730 in Dresden. That time understanding of bryophytes was imprecise and in many cases they were confused with lichens and club mosses. MATERIALS AND METHODS Bryophyte taxa polynomials (18 names) were identified using pre- and post-Linnaean botanical monographs from years 1590 to 1801. Their current names and pharmacological value are provided, as well as the old ethnobotanical data about bryophytes (cited from 18th-century sources). RESULTS Altogether 18 bryophyte species were identified from the vicinity of Warsaw (17 mosses and 1 liverwort). Some of them are still abundant in this area (for example Climacium dendroides, Plagiomnium undulatum and Polytrichum juniperinum) while some other are rare or extinct (for example Neckera crispa and Rhodobryum roseum). CONCLUSIONS Despite the technical ability to observe specific microscopic differences among bryophytes, physicians of 18th century were hardly interested in using any of them as medicinal stock. It may be concluded that the competences in pre-Linnaean bryology did not put into practice using moss-derived materia medica of 18th century (the only exceptions were Fontinalis antipyretica and Polytrichum spp.).

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Analyzing how and why phytotherapeutical practices survive a migratory process is important for understanding migrant health seeking behaviour and health demand. Contrary to most studies, which focus on migrants from warm climates who settle in European and American cities, this study explores continuations in the herbal pharmacopoeia of Eastern European peasants who settled down in rural subtropical areas of Argentina. The study also explores the pharmacopoeia among the descendants of the first generation born in Argentina. MATERIAL AND METHODS Primary and secondary sources were employed in the study. Data were collected during over 200 interviews (semi-structured, free lists and in-depth) with 94 study participants. Voucher specimens of species mentioned were gathered and identified. Illnesses were reported according to local ethnomedical terminology and classification. Only reports from informants' own experience were included in the analysis. The unit of analysis was a plant use report (plant species × plant part × ailment × informant). The frequency of mentions was calculated for plant parts used and modes of preparation and administration of herbal medicines, and the Informant Diversity Value was also estimated. Secondary information was obtained from ethnobotanical and ethnomedical literature concerning the whole of Poland. A list was made of medicinal plant species known from Poland available in the study area. Then, the similarity between the available species and those used by Polish migrants was evaluated by applying the Simpson index. RESULTS An exhaustive list of 129 plant species used by the Polish community in Misiones, Argentina, was obtained. Among 37 species known form Poland and available in Misiones, 19 were used by the community. There was low consensus on the treatment of health conditions with legacy plants between Polish migrants and the Polish folk pharmacopoeia. The reasons for the relatively low use of legacy species are explained. More continuation has been observed in forms of application and administration of medicinal plants. Most of the continued species are food plants and are predominantly applied as medicinal food. CONCLUSIONS In the migratory process, Polish peasants have preserved culturally salient species, which have a wide range of therapeutic applications and are easily accessible. Polish migrants and their descendants have incorporated a great number of local medicinal plant species into their home medicine but at the same time retained traditional ways of administration of herbal medicines. Based on the theory of acculturation, the observed patterns of medicinal plant use in Polish migrant colonies in Misiones indicate good adaptation to the predominant cultural environment.

METHODS In this study, anti-QS activity of ethanol extract of Syzygium cumini L. and Pimenta dioica L. were screened using C. violaceum CV026 biosensor bioassay. By bioassay guided fractionation of S. cumini and P. dioica, ethyl acetate fraction (EAF) with strong anti-QS activity was separated. Inhibition of QS regulated violacein production in C. violaceum ATCC12472 by EAF was assessed at different concentrations. The effect of EAF on the synthesis of autoinducer like N-acyl homoserine lactone (AHL) was studied in C. violaceum ATCC31532 using its mutant C. violaceum CV026 by standard methods. RESULTS EAF inhibited violacein production in C. violaceum ATCC12472 in a concentration dependent manner without significant reduction in bacterial growth. Complete inhibition of violacein production was evidenced in 0.75-1.0 mg/mL concentration of EAF without inhibiting the synthesis of the AHL. TLC biosensor overlay profile of EAF revealed two translucent spots in S. cumini and P. dioica that inhibited C6-AHL mediated violacein production in C. violaceum CV026. CONCLUSIONS This study indicates the anti-QS activity of the tested medicinal plants against C. violaceum.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plant based traditional medicines for birth control has been in practice in rural populations of North-East India, since time immemorial. Fresh rhizome of Drynaria quercifolia (L.) J. Smith is one of the plant parts used traditionally by different ethnic communities in Tripura, India for birth control. The present investigation is aimed to justify the scientific basis in traditional use of Drynaria quercifolia rhizome as anti-fertility agent. MATERIALS AND METHODS Ex-vivo uterotonic activity was done on uterine tissue. Acute toxicity test of the plant extract was carried out in rats of both sexes. The abortifacient and anti-implantation activities of the extract were investigated, in-vivo and estimated the level of different hormones release. RESULTS The result revealed the effectiveness of methanol (87%) and aqueous (68%) extract of the plant on uterotonic activity. The extracts showed relatively non-toxic effect in acute toxicity study. Methanolic extract has shown higher efficacy for both abortifacient (**p<0.01) and anti-implantation performance (**p<0.01) and also effected hormone release level (**p<0.01). CONCLUSION Methanolic extract of Drynaria quercifolia (L.) J. Smith rhizome has been proved to have significant anti-fertility activity.

Abstract
Dog's mercury (Mercurialis perennis L.) is an old medicinal plant, nowadays used in complementary medicine. Aqueous fermented extracts of the plant are being mainly applied in remedies to treat external inflammations, but a thorough phytochemical characterization is still lacking. Therefore, the conversion of characteristic compound classes from M. perennis extracts during fermentation and storage was investigated. The microbial transformation of the two main depsides phaselic acid (=(2R)-O-[(E)-caffeoyl]malic acid; 1) and mercurialis acid (=(2R)-[(E)-caffeoyloxy]glutaric acid; 2) was monitored by HPLC-DAD. The degradation followed a second-order kinetic, and the calculated half-life periods of both constituents were 67 and 30 months, respectively. Several depside metabolites were detected by GC/MS in AcOEt extracts as (t) BuMe2 Si (TBDMS) derivatives after derivatization, mainly dihydrocinnamic acids. Moreover, numerous α-hydroxy acids were found, allegedly as degradation products from amino acids or peptides. The microbial alteration of the main alkaloid hermidin was also examined. After three days of fermentation, three novel N-metabolites were formed and thoroughly assigned in CH2 Cl2 extracts as a mixture of 3-ethylhermidin, 3-ethylhermidin quinone, and (E/Z)-3-ethylidenehermidin by GC/MS and NMR methods, as well as by means of total synthesis. A mechanism for the formation of these N-metabolites starting from dimeric hermidin oxidation products is proposed. The obtained results reveal the complex pathways plant constituents may undergo during the fermentation of the extracts.

Abstract
Diabetes mellitus (DM) is a widely spread epidemic disease that results from the absence of insulin, decreased secretion and/or impaired function. Since DM is a multi-factorial disease, the available pharmaceuticals, despite their sensible treatment, target mostly one pathway to control hyperglycemia and encounter several side effects. Therefore, new therapeutic paradigms aim to hit several pathways using only one agent. Traditionally, antidiabetic plants and/or their active constituents may fulfill this need. More than 200 species of plants possess antidiabetic properties which were evaluated mostly by screening tests without digging far for the exact mode of action. Searching among the different literature resources and various database and in view of the above aspects, the present article provides a comprehensive review on the available antidiabetic plants that have been approved by pharmacological and clinical evaluations, and which their mechanism(s) of action is assured. These plants are categorized according to their proved mode of action and are classified into those that act by inhibiting glucose absorption from intestine, increasing insulin secretion from the pancreas, inhibiting glucose production from hepatocytes, or enhancing glucose uptake by adipose and muscle tissues. The current review also highlights those that mimic in their action the new peptide analogs, such as exenatide, liraglutide and dipeptidylpeptidase-4 inhibitors that increase glucagon-like peptide-1 serum concentration and slow down the gastric emptying.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This study documents the pharmaceutical importance of plant resources in the South-Eastern area of the Partenio Regional Park (PRP), inland Campania, Avellino province. This is reflected in the great diversity of plants used for medicinal purposes as well as in their wide range of medicinal applications. MATERIALS AND METHODS In order to collect information on medicinal plants used in the investigated area and to maximize the collection of local knowledge, informants were randomly contacted in the streets, squares and fields. Data were collected through both open and semi-structured interviews with native people between April 2012 and April 2013. RESULTS The study recorded 87 plant species belonging to 76 genera and 35 families used as medicine for treating various diseases, both human and veterinary. Herbs represent the majority (56 species), followed by trees (18) and shrubs (13). Among the recorded plants, leaves were the most frequently used and topic use is the most common remedy. Cough is the most treated human disease followed by wounds healing. CONCLUSION The investigated area is endowed with a strong tradition of herbal medicine usage for primary healthcare (PHC). The preservation of this knowledge is due to the continued use of plants for PHC by the local community. This is due to the fact that in the study area still exists an oral tradition that allows the persistence of such information. Recovering ancient knowledge is very important for preserving ethno-biodiversity and to discover new entities for a further evaluation of their biological activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Skin diseases have been of major concern recently due to the association of skin opportunistic infections and HIV/AIDS, are usually the first sign of HIV infection and conversion to AIDS. More than 90% of HIV-infected individuals develop skin and mucosal complications at some stage during the disease. Although classical medicine is undoubtedly addressing these diseases, the people of the Eastern Cape, South Africa still depend, to a large extent on traditional herbal medicine for the treatment of various diseases. The current study was undertaken to investigate the local peoples characterisation of skin diseases/disorders and to document the medicinal plants used for various skin disorders among the Xhosa-speaking communities of the Amathole District, Eastern Cape. MATERIALS AND METHODS Information was obtained by interviewing 54 respondents in 7 locations. Collection of the reported medicinal plants from the wild was assisted by the informants and identification of the collected plants specimens was done with the help of floristic works of South Africa. Quantitative methods including the use-value and the informant consensus factor (ICF) were computed for determining the relative importance of species known locally and the homogeneity of the informants׳ knowledge respectively. RESULTS Twenty five skin disorders, classified under 5 categories are being treated with the listed medicinal plants in the study area. The highest ICF (0.45) was linked to bacteria-related skin disorders. This category comprised of 57 use citations, 3 skin disorders; with sore throat being the most frequently mentioned (4.2%). In this study, 106 plant species distributed in 61 families and 107 genera were identified as being used to treat one or more of the skin disorders. The species with the highest use-value was Aloe ferox Mill. (Xanthorrhoeaceae) known locally as Umhlaba. The most representative families were Solanaceae and Asteraceae with 6 species each, followed by Fabaceae, Poaceae and Rutaceae (5 species each). The leaves were the most frequently used plant part, followed by the bark (10%) and fruits (7%). Administration of the different plant parts was mostly topical (77%) on the affected area. CONCLUSION A total of twenty five skin disorders/conditions, classified under 5 categories are being treated with the listed medicinal plants in the study area. 106 plant species distributed in 61 families and 107 genera were identified as being used to treat one or more of the skin disorders. The species with the highest use-value was Aloe ferox Mill. (Xanthorrhoeaceae) known locally as Umhlaba. The most representative families were Solanaceae, Asteraceae, Fabaceae, Poaceae, Rutaceae and Euphorbiaceae. Majority of the plant species were herbs and the leaves were the most frequently used, mostly applied topically as a paste, powder or sap on the affected skin area.

Abstract
BACKGROUND Himalayan region of Pakistan has been known as a rich source for valuable medicinal plants. The present work is the documentation of indigenous knowledge of highly utilized plants as natural remedy by the local inhabitants of the northwest part of the country. METHODOLOGY Data on highly utilized medicinal plants were collected during May-September 2012 using semi-structured questionnaire from the elders, local herbalists and medicinal plants collectors. RESULTS In total about 53, plants belonging to 38, families were highly utilized in the study area, of which majority of those (43), were medicinal plants. The most frequent part used in preparation of different medicinal remedies is leaves (53%). Most of the medicinal plant species (14) were used as antipyretic. The inhabitants of the study area were producing ethno-medicines mostly in crushed form (26%). Most of the remedies (74%), were taken orally within the study area. Ten species were found most valuable from the local's perspective such as Bergenia ciliata, Hedera nepalensis and Viola canescens. CONCLUSION In conclusion, traditional healers depend largely on naturally growing medicinal plant species, which are under severe threat. This study can provide a basis for further phyto-chemical and pharmacological studies on the region's medicinal plants. Moreover, documentation of indigenous recipes would serve as preservation of the knowledge for the generations to come.

Abstract
BACKGROUND/OBJECTIVES In Asia, various medicinal plants have been used as the primary sources in the health care regimen for thousands of years. In recent decades, various studies have investigated the biological activity and potential medicinal value of the medicinal plants. In this study, 100 methanol extracts from 98 plant species were evaluated for their biological activities. MATERIALS/METHODS The research properties, including 1,1-diphenyl-2-pic-rylhydrazyl (DPPH) radical scavenging activity, α-glucosidase and α-tyrosinase inhibitory effects, anti-inflammatory activity, and anticancer activity were evaluated for the selected extracts. RESULTS Fifteen of the extracts scavenged more than 90% of the DPPH radical. Among the extracts, approximately 20 extracts showed a strong inhibitory effect on α-glucosidase, while most had no effect on α-tyrosinase. In addition, 52% of the extracts showed low toxicity to normal cells, and parts of the extracts exhibited high anti-inflammatory and anticancer activities on the murine macrophage cell (RAW 264.7) and human colon cancer cell (HT-29) lines, respectively. CONCLUSIONS Our findings may contribute to further nutrition and pharmacological studies. Detailed investigations of the outstanding samples are currently underway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Juglans regia L. leaf has been traditionally used for treatment of diabetes mellitus in Iran. But yet, no controlled human study has determined its efficacy in diabetic patients. The present study was designed to investigate the effects of the Juglans regia leaf extract on hyperglycemia and lipid profiles in type II diabetic patients. MATERIALS AND METHOD Total 61 patients, suffering from type II diabetes with fasting blood glucose (FBG) between 150 and 200mg/dL, glycated hemoglobin (HbA1c) between 7% and 9% and aged between 40 and 60 years were selected, and randomly divided in to two groups of Juglans regia and placebo. First group received 100mg Juglans regia leaf extract in capsules form two times a day for 3 months and other group received 100mg placebo capsule with the same dosage. The standard anti-diabetic therapy (metformin and glibenclamide, and nutritional regimen) was continued in both groups. At the baseline and after three months the FBG, insulin, HbA1c, cholesterol, triglyceride, HDL, LDL and liver and renal function tests were determined. In addition general satisfaction with the treatment was identified using health questionnaires. RESULTS The results indicated that FBG, HbA1c, total cholesterol and triglyceride levels in Juglans regia treated patients significantly decreased compared with the baseline and with placebo group. Patients in Juglans regia group were significantly satisfied with Juglans regia treatment compared with the placebo group. No liver, kidney and other side effects were observed in the groups, except more GI events (specially a mild diarrhea) associated with extract treatment at the beginning of the study. CONCLUSION In conclusion, treatment of type II diabetic patients with 100mg Juglans regia leaf extract two times a day for three months improves lipid profile and glycemic control without any tangible adverse effects.

Abstract
Hepatitis C virus (HCV) is a global health concern which is responsible for most of the liver diseases. Currently, there is no vaccine available for prevention of HCV infection due to the high degree of strain variation. The current standard of care is a combination of pegylated interferon α with ribavirin and boceprevir/telaprevir. This treatment was partially effective and had significant side effects. Hence, there is a need to develop new antiviral agents that interfere with different stages of the HCV life cycle. Recent advances in the understanding of both the cellular and molecular mechanisms of HCV replication have provided the basis for novel therapeutic strategies. Several hundred plant species and their phyto-constituents have been isolated for screening against HCV, and some have been shown to have great medicinal value in preventing and/or ameliorating viral diseases in pre-clinical and clinical trials. This review summarizes medicinal plants and their phytochemicals which inhibit different stages of HCV life cycle and discuss their potential use in HCV therapy.

Abstract
Medicinal plants are widely used as home remedies and raw materials for the pharmaceutical industries. Herbal remedies are used in the prevention, treatment and cure of disorders and diseases since ancient times. However, use of medicinal herbs may not meet the requirements of quality, safety and efficacy. During harvesting, handling, storage and distribution, medicinal plants are subjected to contamination by various fungi, which may be responsible for spoilage and production of mycotoxins. The increasing consumption of medicinal plants has made their use a public health problem due to the lack of effective surveillance of the use, efficacy, toxicity and quality of these natural products. The increase in use of medicinal plants may lead to an increase in the intake of mycotoxins therefore contamination of medicinal plants with mycotoxins can contribute to adverse human health problems and therefore represents a special hazard. Numerous natural occurrences of mycotoxins in medicinal plants and traditional herbal medicines have been reported from various countries including Spain, China, Germany, India, Turkey and from Middle East as well. This review discusses the important mycotoxins and their natural occurrences in medicinal plants and their products.

Abstract
Trans-caryophyllene is a sesquiterpene present in many medicinal plants' essential oils, such as Ocimum gratissimum and Cannabis sativa. In this study, we evaluated the antinociceptive activity of trans-caryophyllene in murine models of acute and chronic pain and the involvement of trans-caryophyllene in the opioid and endocannabinoid systems. Acute pain was determined using the hot plate test (thermal nociception) and the formalin test (inflammatory pain). The chronic constriction injury (CCI) of the sciatic nerve induced hypernociception was measured by the hot plate and von Frey tests. To elucidate the mechanism of action, mice were pre-treated with naloxone or AM630 30 min before the trans-caryophyllene treatment. Afterwards, thermal nociception was evaluated. The levels of IL-1β were measured in CCI-mice by ELISA. Trans-caryophyllene administration significantly minimized the pain in both the acute and chronic pain models. The antinociceptive effect observed during the hot plate test was reversed by naloxone and AM630, indicating the participation of both the opioid and endocannabinoid system. Trans-caryophyllene treatment also decreased the IL-1β levels. These results demonstrate that trans-caryophyllene reduced both acute and chronic pain in mice, which may be mediated through the opioid and endocannabinoid systems.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional medicine plays a critical role in treatment of chronic debilitating and life threatening conditions and diseases. Cancer is one such condition whose therapeutic intervention is commonly through inexpensive traditional herbal remedies. Increasingly industrialised societies are developing drugs and chemotherapeutics from these traditional herbal plants. Plant biogeography determines the abundance and availability of medicinal plants which in turn determine their use by local communities. The present study was carried out in Kakamega County of Kenya to identify and document medicinal plants used for treatment and management of cancer states by communities living adjacent to Kakamega Tropical rainforest of Kakamega County, Kenya. MATERIALS AND METHODS An ethnobotanical survey was done using semi-structured questionnaires administered to 32 randomly selected herbalists from Kakamega County. RESULTS AND DISCUSSION Sixty five (65) plants of 59 genera and 32 families were identified as candidates in therapeutic intervention against cancer states. Most commonly cited plant species were Spathodea campanulata P. Beauv. ssp. nilotica (Seem), Microglossa pyrifolia (Lam.) Kuntze, Harungana madagascariensis Lam. ex poir, Prunus africana (Hook. f.) kalkman, Cyphostemma serpens (A. Rich), Catharanthus roseus (L.) G. Don and Aloe volkensii Engl. The following were documented for the first time; Aeschynomene abyssinica (A. Rich.) Vatke, Synsepalum cerasiferum (welw.) T. D penn., Albizia coriaria Welw. ex Oliv., Aloe volkensii Engl. Bridelia micrantha (Hochst.) Baill, Croton macrostachyus Delile, Cyphostemma serpens (A. Rich), Dicliptera laxata C.B. Clarke, Ekebergia capensis Sparrm., Gardenia volkensii K. schum. ssp. volkensii, Glycine wightii (wight & Arn.), Ocimum gratissimum Suave, Olea hotcsh spp. hochstetteri, Pavetta abyssinica Fresen., Phyllanthus fischeri Pax, Psydrax schimperiana (A. Rich), Rhus vulgaris Meikle, Senna didymobotyra (Fresen.) Irwin and Barneby, Solanecio nandensis (S. Moore) C. Jeffrey, Solanum mauritianum Scop, Spathodea campanulata P. Beauv. ssp. nilotica (Seem), Spermacoce princea (K. Schum.) Verdc., Tabernaemontana stapfiana Britten, Tragia brevipes Pax and Zanthoxylum gilletii (De Wild.) P.G.Waterman. The most frequently used plant parts were fresh or dried leaves and stem barks. Administration to patients was almost exclusively oral, with the exceptions being topical application especially for breast cancer and skin sarcomas. CONCLUSIONS This study identified diverse medicinal plants used in therapeutic and management intervention against cancer by communities living adjacent to Kakamega Tropical Rainforest. The primary mode of administration was oral.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This is an extensive review of plants used traditionally for women's healthcare in Southeast Asia and surrounding countries. Medicinal plants have a significant role in women's healthcare in many rural areas of the world. Plants with numerous efficacious observations have historically been used as a starting point in the development of new drugs, and a large percentage of modern pharmaceuticals have been derived from medicinal plants. MATERIALS AND METHODS A review was conducted for all plant use mentioned specifically for female healthcare, such as medicine to increase fertility, induce menstruation or abortion, ease pregnancy and parturition, reduce menstrual bleeding and postpartum hemorrhage, alleviate menstrual, parturition and postpartum pain, increase or inhibit lactation, and treat mastitis and uterine prolapse, in 200 studies focusing on medicinal plant use, either general studies or studies focusing specifically on women's healthcare. RESULTS Nearly 2000 different plant species are reported to be used in over 5000 combinations. Most common are Achyranthes aspera, Artemisia vulgaris, Blumea balsamifera, Carica papaya, Curcuma longa, Hibiscus rosa-sinensis, Leonurus japonicus, Psidium guajava and Ricinus communis, and each of these species had been reported in more than 10 different scientific articles. CONCLUSIONS This review provides a basis for traditional plant use in women's healthcare, and these species can be used as the starting point in the discovery of new drugs.

Abstract
Traditional medicinal practices play a key role in health care systems in countries with developing economies. The aim of this survey was to validate the use of traditional medicine within local Nigerian communities. In this review, we examine the ethnobotanical uses of selected plant species from the Nigerian flora and attempt to correlate the activities of the isolated bioactive principles with known uses of the plant species in African traditional medicine. Thirty-three (33) plant species were identified and about 100 out of the 120 compounds identified with these plants matched with the ethnobotanical uses of the plants.

Abstract
Herbal products are commonly used to treat clinical conditions and are often purchased online without the supervision of a healthcare provider. The use of herbals remains controversial because of widespread exaggerated claims of clinical efficacy and safety. We conducted an online search of 13 common herbals (including black cohosh, echinacea, garlic, ginkgo, ginseng, green tea, kava, saw palmetto, and St John's wort) and reviewed the top 50 Web sites for each using a Google search. We analyzed clinical claims, warnings, and other safety information. A total of 1179 Web sites were examined. Less than 8% of retail sites provided information regarding potential adverse effects, drug interactions, and other safety information; only 10.5% recommended consultation with a healthcare professional. Less than 3% cited scientific literature to accompany their claims. Key safety information is still lacking from many online sources of herbal information. Certain nonretail site types may be more reliable, but physicians and other healthcare professionals should be aware of the variable quality of these sites to help patients make more informed decisions.

Abstract
Antiepileptic drugs used to treat epilepsy can cause severe, life threatening side effects. In Iranian traditional medicine, herbal remedies have been used for centuries to treat seizures. In this study, the five most important herbals in Iranian traditional medicine, namely Canon, al-Hawi, al-Abniah 'an Haqaeq al Adwia, Tuhfat al-Mu'minin, and Makhzan ul-Adwia, were searched for the term "sar-e", which means epilepsy, to identify the herbs used for treatment in ancient times. We also searched scientific literature for pharmacological evidence of their effectiveness. Twenty-five plants were identified as herbal remedies to treat epilepsy. Pharmacological data related to the antiepileptic activity of eleven of these plants exists. A large number of these plants which have not been investigated pharmacologically for antiepileptic activity would be good candidates for study in exploring new herbal anticonvulsant remedies.

Abstract
Ocimum gratissimum L. is popularly used to treat diabetes mellitus. The hypoglycemic activity of this medicinal species has been confirmed by in vivo studies. The present study conducted a chemical investigation of a leaf decoction (10% p/v) of O. gratissimum monitored by in vivo hypoglycemic activity assays. Four phenolic substances were identified: L-caftaric acid (1), L-chicoric acid (2), eugenyl-β-D-glucopyranoside (3) and vicenin-2 (4). The acute hypoglycemic activity of the O. gratissimum decoction fractions Og1-S (300 mg/kg), Og1-A (240 mg/kg) and Og1-B (80 mg/kg) was evaluated intraperitoneally in normal and streptozotocin-induced diabetic mice. They reduced glycemia by 63%, 76% and 60% (in 120 min), respectively, in the diabetic mice. Subfractions of Og1-A were also evaluated under the same conditions: Og1-AS (200 mg/kg) and Og1-AP (40 mg/kg) produced a decrease of only 37% and 39%, respectively. Among the major phenolic substances, only chicoric acid (2; 3 mg/kg) reduced significantly the glycemic levels of diabetic mice by 53%, 120 min after treatment. This is the first study describing the hypoglycemic activity of chicoric acid in an animal model of diabetes mellitus. In addition, we suggest that there may be other substances contributing to this activity. Thus, for the first time, a correlation is established between the hypoglycemic activity of O. gratissimum and its chemical composition.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This analysis of documented medicinal plants of the Swiss Flora over the last two millennia provides a rich source of knowledge on earlier uses of plants and use patterns of the local flora. We ask which local plant species were used during different time periods of the last 2000 years and how the numbers of species and the use intensity of specific plant families, growth forms and habitats changed over time. MATERIALS AND METHODS Totally 25 herbals from the antiquity, monastic medicine, Renaissance, early modern era and the contemporary time as well as five recent ethnobotanical studies were considered. Use patterns were analysed with the Bayesian approach. RESULTS A total of 768 species, i.e. 32% of the vascular plants of the Swiss Flora have been documented as medicinal plants. Numbers increase until the monastic period (366 spp.) and the Renaissance (476) and remain relatively stable since then (modern and contemporary era: 477). But, 465 formerly documented species do not occur in the ethnobotanical studies and thus seem not to be used any more. Overall, 104 species are documented through all time periods. Archeophytes, trees and forest plants are generally overrepresented in herbals from all time periods while plants from above the timberline are generally underrepresented. Most widely used are the Lamiaceae and Apiaceae. CONCLUSION A constant body of medicinal plant knowledge in Switzerland exists since ancient time. This knowledge was always influenced by knowledge from neighboring countries and no "typical Swiss specialties" seem to exist. Medicinal plants are not randomly chosen from the available flora. Certain species are deliberately introduced others are neglected. This process, which is still ongoing, can be traced back with the help of herbals to the antiquity.

Abstract
Considering that vaginal delivery is a painful process, the present study investigated the effects of Citrus aurantium on the severity of first-stage labor pain in primiparous women. This study was a randomized clinical trial conducted with 126 eligible primiparous patients. The pain severity of patients was measured at the time of enrolling in the study. In the intervention group, (aromatherapy) gauze squares were soaked in 4 ml of C. aurantium distillated water, and in the control group, gauze squares were soaked in 4 ml of normal saline; each gauze square was attached to the respective patients' collar. The intervention was repeated every 30 min. Pain severity was measured after the intervention at 3-4, 5-7, and 8-10 cm cervix dilatations. The two groups were standardized with regard to age, profession, education, desire to conceive, and number and severity of uterine contractions. The Bishop's score was also calculated. Before intervention, pain severity was the same for both groups, but following intervention, pain severity reduced in the intervention group at 3-4 centimeter (P < 0.05), 7-5 centimeter (P < 0.05), and 8-10 centimeter (P < 0.05) dilatations compared with that in the control group. The findings of the study revealed that aromatherapy using C. aurantium distillated water alleviates labor pain. This method is recommended because of its ease of use and low cost and because it is a non-aggressive method to reduce labor pain.

Abstract
The HPTLC analysis, antioxidant, and antigout activity of Asparagus racemosus, Withania somnifera, Vitex negundo, Plumbago zeylanica, Butea monosperma and Tephrosia purpurea extracts were investigated. The chemical fingerprinting were carried out by high performance thin layer chromatography (HPTLC), antioxidant activity by ABTS, DPPH, FRAP radical scavenging assays, and antiogout activity by cow milk xanthine oxidase. The HPTLC fingerprint qualitatively revealed predominant amount of flavonoids. The TEAC values ranged from 45.80 to 140 µM trolox/100 g dry weight for ABTS, from 85 to 430 µM trolox/ 100 g dw DPPH, and 185 to 560 µM trolox/100 g dw for FRAP respectively. Plants used in this study was found to inhibit the toxicity, as seen from the decreased LPO and increased GSH, SOD and CAT levels. The total phenolic and flavonoid content ranged from 10.21 to 28.17 and 5.80 to 10.1 mg of gallic acid equivalents (GAE)/100 gdw respectively. The plant extracts demonstrated significant xanthine oxidase inhibitory activity at 100 g/mL and revealed an inhibition greater than 50 % and IC50 values below the standard. This effect was almost similar to the activity of allopurinol (Standard drug) against xanthine oxidase (90.2 ± 0.4 %). These plant root extract will be subjected for further extensive studies to isolate and identify their active constituents which are useful for against inflammation and gout.

Abstract
Diabetic Retinopathy (DR) is one of the most common complications of diabetes mellitus that affects the blood vessels of the retina, leading to blindness. The current approach of treatment based on anti-inflammatory, anti-angiogenesis drugs and laser photocoagulation are effective but also shows adverse affect in retinal tissues and that can even worsen the visual abilities. Thus, a safe and effective mode of treatment is needed to control or delaying the DR. Based on the earlier evidence of the potentiality of natural products as anti-oxidants, anti-diabetic and antitumor, medicinal plants may constitute a good therapeutic approach in the prevention of DR. Curcumin, constituents of dietary spice turmeric, has been observed to have therapeutic potential in the inhibition or slow down progression of DR. In this review, we summarize the therapeutic potentiality of curcumin in the delaying the DR through antioxidant, anti-inflammatory, inhibition of Vascular Endothelial Growth and nuclear transcription factors. The strength of involvement of curcumin in the modulation of genes action creates a strong optimism towards novel therapeutic strategy of diabetic retinopathy and important mainstay in the management of diabetes and its complications DR.

ETHNOPHARMACOLOGICAL RELEVANCE This paper represents the first large-scale ethnobotanical study in the Alaşehir and its surrounding (Manisa/Turkey). There are scarcely any studies for using plants. There is urgency in recording such data. This is the first ethnobotanical study in which statistical calculations about plants are done by ICF (Informant Consensus Factor) method. This study aimed to identify plants collected for medicinal purposes by the local people of Alaşehir, located in the Aegean Region of Turkey, and to document the traditional names, preparation and uses of these plants. MATERIALS AND METHODS Field study was carried out over a period of approximately 2 years (2010-2012) in Alaşehir. During this period, 137 vascular plant specimens were collected. Demographic characteristics of participants, local plant names, utilized parts and preparation methods of the plants were investigated and recorded. In the scope of the study, medicinal plant species and related information were collected; herbarium materials were prepared; and the specimens were entitled. Field research was conducted by collecting ethnobotanical information during structured and semi-structured interviews with native knowledgeable people in territory. In addition, the relative importance value of species was determined and ICF was calculated for the medicinal plants included in the study. RESULTS A total of 137 medicinal plants belonging to 58 families were identified in the region. Among them, 105 species are wild and 32 species are cultivated plant. The most dominant medicinal plant families were Asteraceae (>13%), Lamiaceae (>11%), Rosaceae (>7%), and Fabaceae (>4%), again; the most common preparations were infusion and decoction. It was found that Origanum onites L., Urtica urens, Thymus zygioides Griseb., Matricaria chamomilla L., Salvia tomentosa Mill., Cerasus avium (L.), Tilia argentea Desf. ex DC., Hyoscyamus niger L., Urtica pilulifera L., Anethum graveolens L., Euphorbia rigida Bieb., Hypericum perforatum L., Paliurus spina-christi Mill., Rosa canina L., Viscum album L. subsp. austriacum (Wiesb.) Vollman, Silybum marianum (L.) Gaertn., Elymus repens (L.) Gould and Juglans regia L. were the most commonly used species. The traditional medicinal plants have been mostly used for the treatment respiratory tract diseases (14.1%), gastro-intestinal diseases (10%), kidney problems (7.3%), diabetes (7.1%), cholesterol (5%), rheumatism (4%), cancer various (4%), cardiovascular problems (3.1%) and burn (3%). CONCLUSION Gathering, processing and consuming wild edible plants are still practiced in all the studied Alaşehir areas. These plants, used in the treatment of many different diseases, are freely harvested in this region at abundant amounts. Due to the increasing health service facilities in the area, herbal medicine, seemed to be more related to health care and disease prevention than cure.

Abstract
Natural radioactivity levels in some selected medicinal plants commonly used in Ghana from the Centre for Scientific Research into Plant Medicine were investigated to determine the activity concentration and the annual committed effective dose due to naturally occurring radionuclides of (238)U, (232)Th and (40)K. The activity concentration was determined using gamma-ray spectrometry. The results of the analysis indicated an average activity concentration of (238)U, (232)Th and (40)K in the medicinal plants to be 31.8±2.8 Bq kg(-1), 56.2±2.3 Bq kg(-1) and 839.8±11.9 Bq kg(-1) respectively. Khaya ivorensis recorded the highest activity concentration of (238)U and (232)Th while Lippia multiflora recorded the highest activity concentrations of (40)K. The total annual committed effective doses ranged from 0.026±0.001 to 0.042±0.002 mSv a(-1) with an average value of 0.035±0.001 mSv a(-1). The average annual committed effective dose due to ingestion of the natural radionuclides in the medicinal plant samples were far below the world average annual committed effective dose of 0.3 mSv a(-1) for ingestion of natural radionuclides provided in UNSCEAR 2000 report. Therefore, the radiological hazard associated with intake of the natural radionuclides in the medicinal plants is insignificant. The results provide baseline values which may be useful in establishing rules and regulations relating to radiation protection as well as developing standards and guidelines for the use of medicinal or herbal plants to the appropriate authorities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE "Reverse pharmacology", also called "bedside-to-bench" or "field to pharmacy" approach, is a research process starting with documentation of clinical outcome as observed by patients with different therapeutic regimens. The treatment most significantly associated with cure is selected for future studies: first, clinical safety and efficacy; then in vivo and vitro studies. Some clinical data, i.e. details on patient status and progress, can be collected during ethnobotanical surveys; they will help clinical researchers and, once effectiveness and safety are established, will also help users of traditional medicine make safer and more effective choices. To gather clinical data successfully, ethnopharmacologists need to be backed by an appropriate team of specialists in medicine and epidemiology. Ethnopharmacologists can also gather important data on traditional medicine safety. MATERIALS AND METHODS The first step is to create a consensus on the meaning of "clinical data", their interest and importance. An understanding of why "a cure is not a proof of effectiveness" is a starting point to avoid faulty interpretation of the clinical observations. RESULTS Experience showed that, with the "bedside-to-bench" approach, a treatment derived from traditional recipe can be scientifically validated (in terms of safety and effectiveness) with a cost of less than a million euros, thus providing an end-product that is affordable, available and sustainable. CONCLUSIONS With rigorous clinical study results, medicinal plant users gain the possibility to refine heath strategies. The field surveyor may gain a better relationship with the population, once she/he is seen as bringing information useful for the quality of care in the community.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Arrabidaea chica (Bignoniaceae) is a vine native to the Amazon Rainforest, popularly known as "crajiru" and whose infusion and decoction of the leaves are used to treat diseases such as gastric ulcers, inflammations, infections, anemia, herpes, jaundice among others. It is also used as a natural dye. This work aimed to evaluate the in vitro and in vivo toxicity, antimicrobial activity including analysis of chemical constitution of the hydroethanolic extract of the leaves of Arrabidaea chica (HEAc). MATERIALS AND METHODS Acute and subchronic toxicity of HEAc was evaluated in mice and rats, respectively, and by Alamar blue (cytotoxicity assay) using CHO-K1 cells. Antimicrobial activity of HEAc was tested by broth microdilution method using a panel of bacteria and yeast of clinical interest. The preliminary phytochemical analysis of HEAc was performed by electrospray ionization mass spectrometry [ESI(+)-MS]. Secondary metabolites were quantified by colorimetric methods. RESULTS When administered in vivo at doses up to 3000 mg/kg v.o., HEAc did not cause any signs and symptoms of acute toxicity in mice and no cytotoxicity in CHO-K1 cells. Administration for 30 days caused leukocytosis (200 mg/kg) and reversible reductions in non-dose dependent of body weight, total weight gain and feed intake in rats given 200mg/kg and 500 mg/kg of HEAc, but were not accompanied by behavioral and clinical changes (laboratory and histopathological) that may have demonstrated evidences of subchronic toxicity HEAc demonstrated a pronounced activity against Helicobacter pylori (MIC=12.5 μg/mL) and moderate activity against Enterococcus faecalis (MIC=100 μg/mL) in broth microdilution. Preliminary phytochemical analysis of HEAc by colorimetric methods revealed that mainly the presence of phenolic compounds (16.6%), especially flavones and flavonols (4.02%). [ESI(+)-MS] fingerprint analyses of HEAc revealed the presence of 3-deoxyanthocyanidins and kaempferol. CONCLUSION Our data provide evidence that HEAc is safe and can be useful in infections related to Helicobacter pylori and Enterococcus faecalis. Phytochemical analysis revealed the predominant presence of flavones and flavonols, possibly involved in the antimicrobial action of HEAc.

Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Soil pollution due to increasing industrialization is a reality that is taking its toll on mankind today. Considering the population of people that use herbal remedies especially in developing countries and the discharge of industrial waste on surrounding herbal vegetation, it is imperative to determine the heavy metals contamination in some commonly used medicinal plants. MATERIALS AND METHODS Representative samples of five medicinal plants Ageratum conyzoides, Aspilia africana, Alchornea cordifolia, Amaranthus brasiliensis and Chromolaena odorata were collected from Ikpoba-Okha L.G.A, Edo State Nigeria, around a paint company and another set of same plants were collected from a non-polluted source. Dried leaves and roots of collected plants were digested and analyzed using Atomic Absorption Spectrophotometer (AAS) for the presence of Lead (Pb), Cadmium (Cd), Chromium (Cr), Nickel (Ni) and Zinc (Zn). Soil samples from polluted and non-polluted areas were also analyzed to ascertain the levels of these heavy metals in the environment. RESULTS Results show that the concentrations of these heavy metals in the leaves and roots of plants collected from polluted soil were significantly higher than those obtained from unpolluted soil. Correspondingly heavy metal concentrations were significantly higher in polluted than in unpolluted soil samples. CONCLUSION As part of continuing effort in the standardization of traditional remedies, environmental contamination control and abatement is evident. The source of medicinal plants/herbs should also be a cause for concern since the toxicity of medicinal plants is sometimes associated with environmental sources of the plants.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE To provide ethnopharmacological information on the use of medicinal plants for central nervous system (CNS) disorders in the Sinai Peninsula region (Egypt). To collect, analyze and evaluate the ethnobotanical knowledge about these medicinal plants in the Sinai Peninsula region with 61,000 km (2) and 379,000 inhabitants. METHODOLOGY Field work was concluded between March 2006 and May 2011, using semi-structured questionnaire with 700 informants (mean age: 59; 100% men) from 117 settlements of 17 Bedouin tribes. Transects walks in wild herbal plant collection areas and bibliographical review on the collected plants were also conducted. The Interview/ Inhabitant index (I/P), relative importance value of the species and informant consensus factor (FIC) were calculated. RESULTS More than 300 species were traditionally used in folk medicine in the Sinai Peninsula; 101 of these species belonging to 40 families were reported as useful in different CNS disorders. Only 5 species are endemic of the studied area. All different part plants were used, leaves and aerial parts being the most frequent. Most of the remedies were prepared as infusion or decoction, while oral administration was the most common way to be used. Gastrointestinal (67.3%) and respiratory disorders (42.57%) were also reported as frequently treated by Bedouins with herbal remedies. CONCLUSIONS Only a few species were found where the traditional use is supported by pharmacological studies (Acacia nilotica, Achillea fragrantissima, Ajuga iva or Mentha longifolia). No bibliographical references in the scientific literature were found for 22 species (21.78%); finally, several studies were published with different pharmacological activities than those provided by Bedouins.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Long term hyperglycemia leads to development of complications associated with diabetes. Diabetic complications are now a global health problem without effective therapeutic approach. Hyperglycemia and oxidative stress are important components for the development of diabetic complications. Over the past few decades, herbal medicines have attracted much attention as potential therapeutic agents in the prevention and treatment of diabetic complications due to their multiple targets and less toxic side effects. This review aims to assess the current available knowledge of medicinal herbs for attenuation and management of diabetic complications and their underlying mechanisms. MATERIAL AND METHODS Bibliographic investigation was carried out by scrutinizing classical text books and peer reviewed papers, consulting worldwide accepted scientific databases (SCOPUS, PUBMED, SCIELO, NISCAIR, Google Scholar) to retrieve available published literature. The inclusion criteria for the selection of plants were based upon all medicinal herbs and their active compounds with attributed potentials in relieving diabetic complications. Moreover, plants which have potential effect in ameliorating oxidative stress in diabetic animals have been included. RESULTS Overall, 238 articles were reviewed for plant literature and out of the reviewed literature, 127 articles were selected for the study. Various medicinal plants/plant extracts containing flavonoids, alkaloids, phenolic compounds, terpenoids, saponins and phytosterol type chemical constituents were found to be effective in the management of diabetic complications. This effect might be attributed to amelioration of persistent hyperglycemia, oxidative stress and modulation of various metabolic pathways involved in the pathogenesis of diabetic complications. CONCLUSION Screening chemical candidate from herbal medicine might be a promising approach for new drug discovery to treat the diabetic complications. There is still a dire need to explore the mechanism of action of various plant extracts and their toxicity profile and to determine their role in therapy of diabetic complications. Moreover, a perfect rodent model which completely mimics human diabetic complications should be developed.

Abstract
Merwilla plumbea (Lindl.) Speta is an important medicinal plant widely used in traditional medicine. We evaluated the effect of five cytokinins [benzyladenine (BA), 2-isopentenyladenine (2iP), meta-topolin (mT), meta-topolin riboside (mTR), and meta-methoxy-9-tetrahydropyran-2-yl-topolin (MemTTHP)] on the level of phenolic acids and antioxidant activity of M. plumbea during the tissue culture and acclimatization stages. Two cytokinins (mT and mTR) significantly improved the antioxidant activity of tissue culture plantlets while the control plantlets were better after acclimatization. Using UPLC-MS/MS, the levels of hydroxybenzoic and hydroxycinnamic acid derivatives (phenolic acids) varied significantly during tissue culture and acclimatization, depending on the cytokinin and plant part analyzed. Vanillic acid (24.9 μg g⁻¹) detected in underground parts of tissue culture plants supplemented with BA was the most abundant phenolic acid detected. The current findings indicate that the phytochemicals together with the bioactivity during in vitro propagation of M. plumbea is influenced by the cytokinin type used and the stage of plant material collection.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Although medicinal plants are used extensively to treat sexually transmitted infections (STIs) in rural northern Maputaland, KwaZulu-Natal, the efficacy and safety of these plants have not previously been evaluated. AIM OF STUDY A study was designed to investigate the in vitro antimicrobial activity and cytotoxicity profiles of a selection (individual plants and selected combinations) of traditionally used plants in this study area. MATERIALS AND METHODS Aqueous and organic (dichloromethane: methanol, 1:1) extracts were prepared. Antimicrobial activity was assessed using the minimum inhibitory concentration (MIC) assay against the STI associated pathogens; Candida albicans ATCC 10231, Ureaplasma urealyticum clinical strain, Oligella ureolytica ATCC 43534, Trichomonas vaginalis clinical strain, Gardnerella vaginalis ATCC 14018 and Neisseria gonorrhoeae ATCC 19424. For the combination study, interactions were assessed using the fractional inhibitory concentration (ΣFIC). The plant species were assessed for safety using the 3-[4,5-dimethyl-2-thiazol-yl]-2,5-diphenyl-2H-tetrazolium bromide (MTT) cellular viability assay on the human embryonic kidney epithelial (Graham, HEK-293) cell line. RESULTS For the antimicrobial studies, U. urealyticum was the most sensitive of the six test organisms, with the aqueous extract of Ranunculus multifidus (0.02mg/ml) and the organic extract of Peltophorum africanum (0.04mg/ml) being the most antimicrobially active plant species studied. Sclerocarya birrea was found to have the broadest spectrum of activity (mean MIC of 0.89mg/ml). The only plant species to exhibit some degree of cytotoxicity against the kidney epithelial cell line was Kigelia africana (100µg/ml), with 22% and 16% cell death for the aqueous and organic extracts, respectively. Of the 13 combinations studied, several synergistic combinations were evident, the most prominent being the combination of Albizia adianthifolia and Trichilia dregeana (aqueous extract) with an ΣFIC value of 0.15 against O. ureolytica. Synergistic interactions were observed regardless of the ratio of the aqueous mixtures of the two plants. Syzygium cordatum and S. birrea (aqueous extract) was also a combination of interest, demonstrating synergistic (ΣFIC=0.42) interactions against O. ureolytica. This combination, however, also displayed some cytotoxicity towards the human epithelial cell line. CONCLUSION This study demonstrated that anecdotal evidence of plant use does not always correlate with in vitro activity. Furthermore, the toxicological profiling is of utmost importance as if not combined in its correct ratio can lead to potential adverse effects.

Abstract
Twenty samples of herbal soaps were evaluated for their antimicrobial activity against bacteria and yeast of significance in skin infections with the aim to provide some justification for the continued use of the soaps in the management of superficial skin infections. All the soaps were found to possess antimicrobial activity in a concentration and organism dependent manner. The soaps were more active against the gram positive organisms than the Gram negative organisms while none of the soaps had activity against the tested yeasts. Only 35% of the soaps were appropriately packaged with adequate directions for use and storage. The study showed that the tested soaps possessed antimicrobial properties and they can contribute to the treatment and management of skin infections caused by bacteria if well prepared with the appropriate plant materials to target specific causative organisms and packaged with appropriate directions for use and storage.

Abstract
Lippia gracilis, popularly known in Brazil as 'alecrim-de-tabuleiro', is used for many purposes, especially antimicrobial and antiseptic activities. The leaves of three L. gracilis genotypes, including LGRA-106, LGRA-109 and LGRA-110 were collected from the Active Germplasm Bank located in the "Campus Rural da UFS" research farm at the São Cristóvão country, Sergipe State, Brazil. The essential oils were obtained from leaves of L. gracilis plants by hydrodistillation. Chemical analysis of the essential oils was performed by gas chromatography-mass spectrometry (GC-MS). The susceptibility of Trichophyton rubrum strains, MYA3108 and TruMDR2, to the two L. gracilis genotypes (LGRA-106 and LGRA-109) essential oils was determined by the serial microdilution method. Leishmanicidal activity of essential oil from LGRA-106 and LGRA-110 was assayed by tetrazolium-dye (MTT) colorimetric method. The oxygenated monoterpene thymol was the main component of the essential oil from genotype LGRA-106, while Carvacrol was more abundant in LGRA-109 and LGRA-110. The concentrations of LGRA-106 and LGRA-109 essential oils that completely eliminate the fungi were determined and these concentrations were similar to those observed for fluconazole, a common antifungal drug. Among the genotype tested, LGRA-106 essential oil exhibited the best fungicidal activity at 46.87μgmL(-1). Regarding to leishmanicidal activity, the IC50, for LGRA-106 and LGRA-110, was 86.32 and 77.26μgmL(-1), respectively. The results showed that L. gracilis essential oil, rich in thymol and thymol itself presented best antidermatophytic activity, while the best leishmanicidal activity was obtained with essential oil from genotype rich in Carvacrol and Carvacrol itself.

Abstract
Plant species have long been regarded as possessing the principal ingredients used in widely disseminated ethnomedical practices. Different surveys showed that medicinal plant species used by the inhabitants of Jordan for the traditional treatment of diabetes are inadequately screened for their therapeutic/preventive potential and phytochemical findings. In this review, traditional herbal medicine pursued indigenously with its methods of preparation and its active constituents are listed. Studies of random screening for selective antidiabetic bioactivity and plausible mechanisms of action of local species, domesticated greens, or wild plants are briefly discussed. Recommended future directives incurring the design and conduct of comprehensive trials are pointed out to validate the usefulness of these active plants or bioactive secondary metabolites either alone or in combination with existing conventional therapies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pelargonium sidoides DC (Geraniaceae), a popular medicinal plant used in folk medicine in the treatment of respiratory-related infections has gained international prominence due to its usage in several herbal formulations. This has led to high demand and the subsequent decimation of wild populations. AIM OF THE STUDY Using plant tissue culture techniques, Pelargonium sidoides plants were cloned in vitro, acclimatized under greenhouse conditions and evaluated for their phytochemical content and pharmacological activity. METHODS Phenolic content in extracts of in vitro-derived, greenhouse-acclimatized and wild Pelargonium sidoides plants were analyzed using UPLC-MS/MS. The oxygen radical absorbance capacity (ORAC), 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activity and minimum inhibitory concentration (MIC) of the extracts against bacterial and fungal strains were evaluated. RESULTS Similarities in phenolic profiles were identified confirming the chemical signatures that characterize Pelargonium sidoides plants. Extracts of greenhouse-acclimatized and wild plants exhibited comparable antimicrobial and antioxidant properties. CONCLUSIONS Overall, the study highlights the potential of integrating plant tissue culture technologies in conservation strategies of medicinal plants. In particular, the results strongly suggest the feasibility of both large-scale cultivation and plant part substitution as alternative solutions to the current destructive overharvesting practices of wild Pelargonium sidoides populations.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Several medicinal plants are traditionally traded in open-air markets in Rio de Janeiro State (Brazil) to treat tuberculosis (TB) and related symptoms. AIMS OF THE STUDY Conduct a survey in the open-air markets of 20 cities of Rio de Janeiro State to find medicinal plants that are popularly used to treat tuberculosis and other related diseases and assess their in vitro antimycobacterial activity. MATERIALS AND METHODS We used direct observation and semi-structured interviews and asked herbalists to list species (free listing) in order to gather data about the plant species most commonly used for lung problems. We calculated a Salience Index and acquired two species of "erva-de-passarinho" (mistletoe), Struthanthus marginatus and Struthanthus concinnus (Loranthaceae), commonly used to treat tuberculosis for a bioassay-guided isolation of the antimycobacterial active principles. Extracts, fractions and isolated compounds of both species were assayed in vitro against susceptible (H37Rv) and rifampicin-resistant (ATCC 35338) Mycobacterium tuberculosis strains. RESULTS From the interviews, we generated a list of 36 plant species belonging to 12 families. The mistletoes Struthanthus marginatus and Struthanthus concinnus showed high Salience Index values among plants used to treat tuberculosis. Bioassay-guided fractionation of hexane extracts from both species led to the isolation and/or identification of steroids and terpenoids. The Minimum Inhibitory Concentration (MIC) of the extracts and isolated compounds ranged from 25 to 200 μg/mL. Some of the isolated compounds have been previously assayed against Mycobacterium tuberculosis, others are reported here for the first time (obtusifoliol: MIC H37Rv 50 μg/mL, MIC ATCC 35338 12.5 μg/mL; 3-O-n-acil-lup-20(29)-en-3β,7β,15α-triol: MIC H37Rv 200 μg/mL, MIC ATCC 35338 100 μg/mL). CONCLUSIONS This study demonstrated the importance of ethnobotanical surveys in markets as a source for new drugs and also for scientific validation of folk medicine.
