Abstract
The average worldwide human life expectancy is 70 years, with a significantly higher value in Western societies. Many modern diseases are not associated with premature mortality but with a decreased quality of life in aged patients and an excessive accumulation of various toxic compounds in the human body during life. Today, scientists are especially interested in finding compounds that can help increase a healthy lifespan by detoxifying the body. Phytotherapy with specific approaches is used in alternative medicine to remove toxins from the body. Worldwide, research is conducted to identify medicinal plant-derived molecules that, with few or no side effects, may protect the liver and other organs. This review provides updated information about the detoxification process, the traditional and modern use of the most effective medicinal plants, their active metabolites as detoxifying agents, and the mechanisms and pathways involved in the detoxification process. Among medicinal plants with substantial detoxifying properties, a major part belongs to the Asteraceae family (Silybum marianum, Cynara scolymus, Arctium lappa, Helichrysum species, Inula helenium, and Taraxacum officinale). The most widely used hepatoprotective phytocomponent is silymarin, a standardized extract from the Silybum marianum seeds containing a mixture of flavonolignans. Many polysaccharides, polyphenols, and terpenoids have a detoxifying effect. Overall, scientific data on medicinal plants used in phytotherapeutic practice worldwide provides an understanding and awareness of their efficacy in detoxification.

Abstract
Recently, the effect of an aqueous extract of asafetida on acute angiotensin II hypertensive rats was evaluated. The present study evaluated the antihypertensive and antioxidant effects of asafetida on a rat model of renovascular hypertension (RVH) using four groups. RVH was induced by clipping the renal artery; the sham group underwent surgery but without clipping. The RVH rats received losartan (Los, an AT1 receptor antagonist) or asafetida by gavage for 4 weeks. On the 28th day, the femoral artery was cannulated, and the systolic blood pressure (SBP), mean arterial pressure (MAP), and heart rate (HR) were recorded. Finally, the levels of superoxide dismutase (SOD) activity, malondialdehyde (MDA), and total thiol content in the kidney and heart tissues were measured. In RVH rats, SBP and MAP significantly increased compared with the control. Los and the extract significantly reduced the changes in SBP, MAP, and HR that were induced in the RVH rats (P <0.05-0.001). In RVH rats, levels of MDA significantly increased and the content of total thiol and SOD decreased in both the heart and kidney tissues. Los plus the extract significantly decreased MDA and increased total thiol and SOD in the heart and kidney tissues. We concluded that an aqueous extract of asafetida gum has antihypertensive and antioxidant effects in the RVH rat model. The effect of the extract is similar to that of Los, which suggests that this effect of asafetida is mediated via an effect on the angiotensin Type I receptor.

A Systematic Review of Phytochemistry, Nutritional Composition, and Pharmacologic Application of Species of the Genus Viola in Noncommunicable Diseases (NCDs). EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2023; 2023:5406039. [PMID: 37941895 PMCID: PMC10630019 DOI: 10.1155/2023/5406039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 06/03/2023] [Accepted: 10/11/2023] [Indexed: 11/10/2023]
Abstract
Viola L. is the largest genus of the Violaceae family with more than 500 species across the globe. The present extensive literature survey revealed Viola species to be a group of important nutritional and medicinal plants used for the ethnomedicinal treatment of noncommunicable diseases (NCDs) such as diabetes, asthma, lung diseases, and fatigue. Many plant species of this genus have also received scientific validation of their pharmacological activities including neuroprotective, immunomodulatory, anticancer, antihypertensive, antidyslipidemic, analgesic, antipyretic, diuretic, anti-inflammatory, anthelmintic, and antioxidant. Viola is highly rich in different natural products some of which have been isolated and identified in the past few decades; these include flavonoids terpenoids and phenylpropanoids of different pharmacological activities. The pharmacokinetics and clinical studies on this genus are lacking, and the present review is aimed at summarizing the current understanding of the ethnopharmacology, phytochemistry, nutritional composition, and pharmacological profile of medicinal plants from the Viola genus to reveal its therapeutic potentials, gaps, and subsequently open a new window for future pharmacological research.

Abstract
Purpose This study aimed to assess and compile the available research articles about medicinal plants used for ocular diseases. Principal results A total of 2949 articles were retrieved, 35 full-text articles were assessed for eligibility, and seven studies (4 observational and three experimental) with low to moderate quality were eligible and involved in the systematic review, with a total of 600 plants from 4 countries. Among the 600 plants, only 24 (4%) were used to assess the status. Both the fixed and random models of the studies showed that the included studies tended to predict the results for the observational studies (OR = 0.062, CI = 0.043-0.090 OR = 0.039, CI = 0.012-0.122) for different plants used for ocular diseases. High heterogeneity (estimated as I2 = 87.078, Tau2 = 1.161 and Q-value = 23.217 with a p-value of 0.000), while for experimental studies (I2 = 94.928, Tau2 = 23.211 and Q-value = 39.434 with a p-value of 0.000) and publication bias were reported. Conclusion Few articles representing approximately 600 plants of low to moderate quality reported using medicinal plants for ocular diseases. The meta-analysis confirmed the systematic review findings regarding the plants' traditional use with high heterogeneity and publication bias. A considerable gap was proven in the use of medicinal plants in ocular diseases requiring intensive research.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is one of the most common pulmonary diseases. The current therapeutic outcomes are not satisfactory and may cause adverse events such as cardiovascular complications. In this study, we aimed to discuss some effective medicinal herbs for the management of COPD. Materials and Methods In this review, we looked for effective medicinal herbs for productive cough with thick and sticky mucus in Persian medicine sources such as Qanoon fi al-Teb, Exir Azam, and Zakhire Kharazmshahi. Then, to find relevant evidence about them, the data sources (PubMed and Google Scholar) were searched in the English language without time restriction from inception up to March 2022. Results We found that Zataria multiflora, Thymus vulgaris L, Glycyrrhiza glabra L., Crocus sativus L., Nepeta bracteata Benth., and Hyssopus officinalis have beneficial effects on COPD due to their properties including anti-inflammatory and antioxidant activity. In addition, considering asthma COPD overlap (ACO), medicinal herbs including Cordia myxa, Adiantum capillus-veneris, Cinnamomum verum, Viola odorata, Borago officinalis, Linum usitatissimum and Vitis viniferia L. were found to have useful effects on asthma. Conclusion Considering the mentioned beneficial mechanisms of action of these medicinal herbs, they could be used as a complementary therapy in COPD and asthma. However, more experimental and clinical research should be done to confirm their clinical effects.

Abstract
Ricinodendron heudelotii stem bark is commonly used in Cameroonian traditional medicine to treat cardiovascular diseases such as hypertension. The present study was designed to investigate the antihypertensive and antioxidant properties of the aqueous extract of Ricinodendron heudelotii in salt-induced hypertensive rats. Analysis by HPLC-ESI-Q-TOF-MS was used to identify various chemical components of the extract. A total of thirty rats were used for each test. High-salt hypertension was induced in rats by oral administration of NaCl for 12 weeks. Mean blood pressure (MBP) and heart rate (HR) were monitored by noninvasive methods. Oral administration of Ricinodendron heudelotii significantly (
) reduced the increase of mean blood pressure (23.12%, 26.14%, and 24.34%) and heart rate (31.19%, 31.09%, and 26.98%), respectively, at the doses of 40, 20, and 6 mg/kg, compared to the hypertensive group. All the doses tested significantly reduced or/and ameliorated biochemical and oxidative stress parameters. Histological analysis showed that Ricinodendron heudelotii restored renal disorders induced by the administration of salt. The aqueous extract of Ricinodendron heudelotii exerts a cardioprotective effect, and the antihypertensive activity seems associated with an improvement in antioxidant status. Overall, the results justify and support the traditional use of Ricinodendron heudelotii.

Abstract
Traditional medicine is a comprehensive term for ancient, culture-bound health care practices that existed before the use of science in health matters and has been used for centuries. Medicinal plants are used to treat patients with cardiovascular diseases, which may occur due to ailments of the heart and blood vessels and comprise heart attacks, cerebrovascular diseases, hypertension, and heart failure. Hypertension causes difficulty in the functioning of the heart and is involved in atherosclerosis, raising the risk of heart attack and stroke. Many drugs are available for managing these diseases, though common antihypertensive drugs are generally accompanied by many side effects. Medicinal herbs have several active substances with pharmacological and prophylactic properties that can be used in the treatment of hypertension. This review presents an overview of some medicinal plants that have been shown to have hypotensive or antihypertensive properties.

Abstract
Objective This study determines the efficacy and probable underlying mode of action to the folk usage of Euphorbia hirta, Fagonia indica and Capparis decidua in hypertension. Methods The aqueous-methanol extracts of E. hirta (EH.Cr), F. indica (FI.Cr) and C. decidua (CD.Cr) were tested for antihypertensive effects in rats using non-invasive and in-vasive blood pressure measuring apparatus. In-vitro assays were carried out using isolated rat aortae using PowerLab station. Results EH.Cr, FI.Cr and CD.Cr at 500 mg/kg (orally) caused a fall in the mean systolic blood pressure in arsenic-induced hypertensive and normotensive rats, similar to nifedipine. In rat aortae, EH.Cr, CD.Cr and FI.Cr reversed low (20 mM), high (80 mM) K+ and phenylephrine (P.E)-driven contractions, while F. indica partially inhibited high K+ contractions. In the presence of TEA, F. indica remained unable to relax low K+ contractions. EH.Cr and CD.Cr moved Ca++ concentrations response curves to the right, like nifedipine. All fractions of EH.Cr and CD.Cr except aqueous, pet-ether and chloroform fractions of FI.Cr displayed Ca++ antagonistic activity. FI.Cr, its ethyl acetate and aqueous fraction exhibited TEA-sensitive potassium channel activation. On baseline tension, test materials also produced phentolamine-sensitive vasospasm. Conclusion E. hirta, F. indica and C. decidua possess antihypertensive activity in arsenic-induced hypertensive rats possibly mediated via endothelium-dependent vasorelaxation. In normotensive rats, E. hirta and C. decidua showed antihypertensive activities through endothelium-dependent and Ca++ antagonistic pathways, while F. indica exhibited potassium channel activation and Ca++ antagonistic like effects in its vasorelaxation. Additional weaker vasospastic effects were derived through α-adrenergic like pathways.

Abstract
Background Functional constipation (FC) is a health concern that is prevalent in the pediatric population. It lowers the quality of life and increases the probability of comorbidities. As a complementary modality, herbal medicine has been considered useful in a variety of conditions. Persian medicine (PM) resources mention the Viola flower as an effective herb in treating constipation. The purpose of the current trial was to evaluate the efficacy of Viola flower syrup (VFS) compared with polyethylene glycol (PEG) in children with functional constipation. Methods This randomized, active-controlled, single-center trial was conducted on 140 children aged between 4 and 10 years with confirmed FC according to Rome III criteria. Participants were randomly assigned to receive either VFS or PEG for four weeks. Independent t-test and general linear model (GLM) repeated measures analysis of variance were used to determine the intergroup difference, and paired sample t-test was used to evaluate the intragroup difference. Results After four weeks of intervention, 133 individuals (66 in VFS and 67 in the PEG group) were analyzed. Results of both groups demonstrated significant improvement in all measured criteria at the end of the study compared to baseline (P < 0.001). No significant difference was observed between the two groups at baseline or at the end of the study (P > 0.05), except for fecal retention at baseline (P=0.028). Participants in the PEG group experienced more side effects compared to the VFS group. Conclusion The findings of this investigation indicated that VFS is an effective and relatively safe medication to be used in the treatment of pediatric FC.

Abstract
Traditional medicine and the use of herbal remedies are well established in the African health care system. For instance, Violaceae plants are used for antimicrobial or anti-inflammatory applications in folk medicine. This study describes the phytochemical analysis and bioactivity screening of four species of the violet tribe Allexis found in Cameroon. Allexis cauliflora, Allexis obanensis, Allexis batangae and Allexis zygomorpha were evaluated for the expression of circular peptides (cyclotides) by mass spectrometry. The unique cyclic cystine-rich motif was identified in several peptides of all four species. Knowing that members of this peptide family are protease inhibitors, the plant extracts were evaluated for the inhibition of human prolyl oligopeptidase (POP). Since all four species inhibited POP activity, a bioactivity-guided fractionation approach was performed to isolate peptide inhibitors. These novel cyclotides, alca 1 and alca 2 exhibited IC50 values of 8.5 and 4.4 µM, respectively. To obtain their amino acid sequence information, combinatorial enzymatic proteolysis was performed. The proteolytic fragments were evaluated in MS/MS fragmentation experiments and the full-length amino acid sequences were obtained by de novo annotation of fragment ions. In summary, this study identified inhibitors of the human protease POP, which is a drug target for inflammatory or neurodegenerative disorders.

Abstract
Background: Asafoetida is an oleo-gum-resin obtained from the rhizome of Ferula assa-foetida plant that its effects on hypertension have been reported. This study examines the effect of aqueous extract of asafoetida on the cardiovascular parameters in acute hypertension induced by angiotensin II (AngII). Materials and Methods: Thirty-six male rats were divided into six groups including Group 1: control; Group 2: AngII (50 ng/kg, intravenous); Group 3: losartan (Los; 10 mg/kg, i. p) + AngII; and Groups 4, 5, and 6 that received three doses of asafoetida (10, 30, and 60 mg/kg, i. p), separately. Los and extract were injected 30 min before hypertension induced by AngII. The femoral artery was cannulated and was connected to a pressure transducer, and cardiovascular parameters (systolic blood pressure [SBP], mean arterial pressure [MAP], and heart rate [HR]) were continuously recorded by a Power Lab system. The changes (Δ) of parameters were calculated and used for statistical analysis. Results: AngII significantly increased the value of Δ SBP and Δ MAP compared to the control and significantly decreased Δ HR value. Injection of Los attenuated increased cardiovascular responses by AngII. Three doses of asafoetida ameliorated cardiovascular responses by AngII. Three doses of asafoetida decreased the Δ HR non significantly compared to AngII. Conclusion: Our results indicated that aqueous extract of asafoetida ameliorated cardiovascular responses in acute hypertension induced by AngII. This effect in a lower dose was more effective and comparable with Los. Therefore, a part of antihypertensive effect of asafoetida is mediated through inhibition of the AngII receptor type 1 receptor of AngII.

Abstract
BACKGROUND The effect of hydroalcoholic extract of Ziziphus jujuba (ZJ) on hypertension has been reported previously. OBJECTIVE This experiment investigates the effect of two ethyl acetate (EA, a polar and semi-polar compound) and aqueous fractions (AQ, a polar compound) of ZJ extract on cardiovascular parameters in acute hypertension induced by angiotensin II (AngII). METHODS Rats were randomly divided into following groups (n=7 in each group): 1) Control; 2) AngII (50 ng/kg); 3) Losartan (LOS, 30 mg/kg) + AngII; 4, 5) ethyl acetate fraction (EA150 and EA300 mg/kg) + AngII and 6, 7) aqueous fraction (AQ150 and AQ300 mg/kg) + AngII. Rats were treated with both fractions and LOS orally for four weeks and in the experiment day (28th) AngII intravenously injected and cardiovascular parameters (Systolic Blood Pressure (SBP), Mean Arterial Pressure (MAP) and Heart Rate (HR)) directly were recorded by a power lab system. RESULTS AngII could significantly increase SBP and MAP (P<0.001) and decrease HR with respect to the control and these responses were attenuated by LOS. The SBP and MAP in both doses of EA+ AngII and the higher dose of AQ fractions + AngII were significantly lower than the AngII group (P<0.05 to P<0.001). Bradycardia induced by AngII was also reduced by LOS and both fractions. The comparison of two fractions also showed that the effect of EA fraction is greater than the AQ. CONCLUSION This study indicates that both fractions of the ZJ extract have a beneficial effect on hypertension. Because effect of EA was greater than AQ, we suggested that antihypertensive effects of ZJ mediated polar and nonpolar compounds.

Abstract
The burden of obesity is increasing all over the world. Except for Orlistat, no effective anti-obesity drug is currently available. Therefore, a search for the new anti-obesity compound is need of time. This study demonstrates macromolecular interaction and inhibitory effect of pentacyclic triterpenoids (PTT) on pancreatic lipase (PL). In the present study PTTs from endophytic Colletotrichum gigasporum were found to show significant inhibitory activity against PL with IC50 of 16.62 ± 1.43 μg/mL. The PTT isolated through bioassay-guided isolation showed a dose-dependent (R2 = 0.915) inhibition against porcine PL and the results were comparable with the standard (Orlistat). Based on inhibition kinetic data, the gradual increase in Km (app) with increasing PTT concentration indicated that the mode of interaction of PTT with PL was a competitive type, and it directly competed with the substrate (pNPB) for the active site of PL. In vivo studies in Wistar rats at the oral dose (100 mg/kg body weight) of PTT significantly decreased (p < 0.05) incremental plasma triglyceride levels as compared to group B and TG absorption was down-regulated up to 49.18% vis a vis group D animals. The isolated PTT was identified as lupeol based on chromatographic and spectral data. The endophytic isolate was identified as Colletotrichum gigasporum based on morphology and ITS gene sequencing. The present study indicated that PTT had the potential to be used as a natural PL inhibitor in the treatment of obesity and the isolated endophyte can be a valuable bioresource for it.

Abstract
BACKGROUND Otostegia integrifolia Benth. (Lamiaceae) leaves are used to treat hypertension in Ethiopian folk medicine. However, the claim has so far not been investigated scientifically. Thus, the objective of this study was to evaluate the antihypertensive activity of 80% methanol leaf extract of O. integrifolia in animal model of hypertension and possible underlying mechanisms in isolated rat aorta. METHODS Antihypertensive effect of various oral doses of the extract (250, 500 and 1000 mg/kg) was determined in fructose-induced hypertensive rats using the non-invasive tail-cuff method. Thoracic aortic strips of rats were isolated and suspended in organ bath, and the vasodepressor effect as well as the possible mechanism (s) of action were studied by means of isometric tension recording experiments ex vivo. Phytochemical analysis was also performed to suggest possible constituents related to the activity. RESULTS Blood pressure was significantly lowered in a dose-dependent manner following extract administration, suggesting that the extract possesses antihypertensive activity. The extract also caused a dose-dependent relaxation of aortic strip precontracted with KCl at a concentration of 6.25-125 μg/L, with a maximum relaxation (100%) achieved at a cumulative concentration of 318.75 μg/ml. The relaxation mechanism was found to be independent of muscarinic receptors, prostanoids, histamine receptors, ATP dependent K+ channels, sarcoplasmic reticulum stored Ca2+ and the endothelium system. The extract shifted the Ca2+ concentration-response curve to the right similar to that caused by nifedipine, suggesting that vasorelaxation could possibly be mediated via calcium channel blockade. The extract was found to contain phenolic compounds (164.3 mg/g, expressed as gallic acid equivalents) and flavonoids (125.7 mg/g, expressed as quercetin equivalents). CONCLUSION The findings revealed that the plant is endowed with antihypertensive activity, providing evidence for its traditional use. The effect maybe, at least in part, due to dilation of blood vessels through blockade of Ca+ 2 channels mediated by phenolic and flavonoid constituents.

Abstract
Cardiovascular diseases are responsible for high morbidity and mortality rates worldwide. Among treatment options, medicinal plants are frequently used, especially in developing countries, such as Brazil. Despite social development that has been observed in the last decades, the use of medicinal plants is still driven by popular knowledge, especially by healers. The present study sought to identify medicinal species that are used for the treatment of cardiovascular diseases by healers in the microregion of Francisco Beltrão, Paraná, Brazil. The snowball technique was used to select informants, and data were collected through interviews. The research was performed in two stages: (1) a structured interview and (2) the collection and botanical identification of the species that were mentioned by the healers. Medicinal plants were classified into the following categories of cardiovascular agents: hypotensive and antihypertensive agents, lipid-lowering agents, diuretic agents, and cardiotonic agents. To analyze the data, the frequency was determined, Spearman correlations were calculated, and the informant consensus factor (ICF) and use value were obtained. Some characteristics, such as female gender and old age, were associated with knowledge about medicinal plants. Overall, 77 different species and 149 medicinal uses were cited by the healers. With regard to categories of use, the highest number of species was found among lipid-lowering plants, and the highest ICF was found for species that are used as cardiotonics. Moreover, a literature review indicated that among the cited species, several still lack studies that have proven their effects on the cardiovascular system. The traditional use of medicinal plants for the treatment of cardiovascular diseases is broad in the study regions. The present results are important for clarifying popular knowledge in this region and providing a framework for selecting species with potential for the development of new pharmacological studies.

Abstract
Traditionally, in the Southern Asian countries, Psidium cattleyanum is a widely used plant for the management of various ailments such as gastrointestinal, respiratory, and cardiac disorders, but it lacks proof on a scientific basis, and therefore, this is the major emphasis of the current research work. Crude extract of Psidium cattleyanum (Pc.Cr) was preliminary analyzed for the presence of different classes of bioactive molecules. The aqueous and dichloromethane fractions of Pc.Cr were subjected to in vitro and in vivo studies. It was applied at variable concentrations (0.1-10 mg/ml) to isolated rabbit jejunum to investigate spasmolytic effect. Concentration dependent curves of calcium were constructed to check the calcium channel antagonistic activity. For the evaluation of tracheorelaxant activity, isolated tracheal tissue was treated with High-K+ (80 mM) and carbachol (CCh) and then challenged cumulatively with Pc.Cr. To study the antidiarrheal effect of the plant extract, castor oil-induced diarrhea model was adopted. For evaluation of the hypotensive effect of Pc.Cr, it was given intravenously to preanesthetized normotensive rats, and the response was recorded using pressure transducer. Platelet rich plasma was used for the assessment of the antiplatelet activity when challenged with purinergic and adrenergic agonists. Concentration-dependent inhibition of spontaneous and High-K+ mediated contractions in isolated jejunum was observed by the application of Pc.Cr. Contractions induced in isolated tracheal tissue by High-K+ and CCh were inhibited by application of Pc.Cr to these tissues. Similarly, application of Pc.Cr to High-K+ and phenylephrine (PE) treated aortic strips resulted in vasodilation. Platelet aggregation inhibition was shown by Pc.Cr against adenosine diphosphate (ADP) only. The antidiarrheal effect was observed as a reduction in the total number of feces in Pc.Cr-treated mice when given castor oil. Dose-dependent hypotension was seen in normotensive rats when treated with Pc.Cr intravenously. This study showed the spasmolytic, tracheorelaxant, vasodilator, platelet aggregation inhibitory, antidiarrheal, and hypotensive activities of P. cattleyanum which may be due to the blockage of calcium channels, but the involvement of any other pathway cannot be ignored.

Abstract
Primary hypertension describes abnormally-high systolic/diastolic blood pressure in a resting condition caused by various genetic or environmental risk factors. Remarkably, severe complications, such as ischemic cardiovascular disease, stroke, and chronic renal disease have led to primary hypertension becoming a huge burden for almost one-third of the total population. Medication is the major regimen for treating primary hypertension; however, recent medications may have adverse effects that attenuate energy levels. Hence, the search for new hypotensive agents from folk or traditional medicine may be fruitful in the discovery and development of new drugs. This review assembles recent findings for natural antihypertensive agents, extracts, or decoctions published in PubMed, and provides insights into the search for new hypotensive compounds based on blood-pressure regulating mechanisms, including the renin-angiotensin-aldosterone system and the sympathetic/adrenergic receptor/calcium channel system.

Abstract
The emergence of rapidly evolving multidrug-resistant pathogens and a deficit of new compounds entering the clinical pipeline necessitate the exploration of alternative sources of antimicrobial therapeutics. Cyclotides revealed in Viola spp. are a class of highly stable, cyclic, and disulfide-bound peptides with diverse intrinsic bioactivities. Herein we have identified a novel complement of 42 putative cyclotide masses in the plant species Viola inconspicua. Cyclotide-containing fractions of a V. inconspicua peptide library revealed potent bioactivities against the Gram-negative bacteria Escherichia coli ATCC 25922 and the highly virulent and multidrug-resistant Klebsiella pneumoniae VK148. As such, six previously uncharacterized cyclotides, cycloviolacins I1-6 (cyI1-cyI6), were prioritized for molecular characterization. Cyclotides cyI3-cyI6 contain a novel "TLNGNPGA" motif in the highly variable loop six region, expanding the already substantial sequence diversity of this peptide class. Library fractions comprised of cyclotides cyI3-cyI6 exhibited MIC values of 18 and 35 μM against E. coli and K. pneumoniae, respectively, whereas isolated cyI3 killed ∼50% of E. coli at 60 μM and isolated cyI4 demonstrated no killing at concentrations >60 μM against both pathogens. This work expands the repertoire of bioactive cyclotides found in Viola spp. and highlights the potential of these antibacterial cyclic peptides.

Abstract
Hypertension is highly prevalent among the Lebanese adult population and is indeed the major cause of mortality in Lebanon. Traditional use of antihypertensive medicinal plants has long been practiced. The aim of this study is to document this traditional knowledge and clinically test the antihypertensive capacity of three of the most commonly used wild plant species Mentha longifolia, Viola odorata and Urtica dioica. Ethno-pharmacological data was collected by personal interviews with herbalists and traditional healers using a semi structured survey questionnaire and assessing relative frequency of citation (RFC). The clinical study was conducted by a randomized, blind, placebo-controlled trial in 29 subjects with mild hypertension distributed in four groups, three plant extract treatments and one placebo. Systolic (SBP) and diastolic blood pressures (DBP) as well as mean arterial blood pressures (MAP) were monitored at weeks 4, 8, 12 and 16 during the treatment with 300 mL/day of plant extract. Results showed that M. longifolia, U. dioica and V. odorata exhibited the highest values of RCF (0.95) followed by Allium ampeloprasum (0.94), Apium graveolens (0.92) and Crataegus azarolus (0.90). The clinical trial revealed dose- and duration-dependent significant reductions in SBP, DBP and MAP of subjects treated with M. longifolia, U. dioica or V. odorata. Our findings indicate that extracts of these plants present an effective, safe and promising potential as a phyto-therapuetical approach for the treatment of mild hypertension. More research on the phytochemistry, pharmacological effects and the underlying mechanisms is necessary.

Abstract
For neurological disorders, pharmacological tests have shown promising results in the reduction of side effects when using plants with known therapeutic effects in the treatment of some types of dementia. Therefore, the goals of this study are to gather data about the major medicinal plants used in the nervous system as described in ethnopharmacological surveys from South America and Brazil and to compare this data with the results from pharmacological tests on the active principles of those same plants found in the scientific literature. After collecting the data about each plant, their respective popular indication was compared with the results found through pharmacological tests. The discrepancy rate between the effects observed by ethnopharmacological and pharmacological methods in this study is greater than 50%. In conclusion, despite the importance of ethnopharmacological data, it is important to make comparisons with pharmacological tests for the same plants, since the pharmacological studies, although few, have shown a high rate of discrepancy in the results.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Violet oil is an ancient herbal drug which has been extensively used to treat insomnia in traditional Iranian Medicine clinics. Violet oil is an almond or sesame oil-based extract of Viola odorata, which is administered as nasal drops. This study aimed to evaluate the efficacy of Violet oil in the treatment of insomnia. METHODS AND MATERIALS This study was conducted as a 3-arm double-blind randomized trial. A total of 75 patients with chronic insomnia were enrolled and randomly assigned to three groups in Traditional Iranian Medicine Clinic of Mashhad University of Medical Sciences, Mashhad, Iran. The treatment consisted of intranasal dropping of Violet oil, Almond oil or placebo (1% solution of Carboxymethyl cellulose) in each nostril every night before sleep for 30 days, i.e. three drops of the drug (including either Violet oil or Almond oil) or the placebo was used every night before the sleep. All the patients were asked to complete Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) questionnaires before and after the intervention. RESULTS There were no significant differences between patients in the three groups before the intervention (P > 0.05). However, there were significant differences between the three groups after the intervention in ISI scores (P<0.002) and PSQI scores (p<0.001). When comparing the pre- and post-treatment data, the ISI and PSQI scores improved significantly in all the three groups as follows: Violet oil (P<0.001), Almond oil (P<0.001) and placebo (P<0.001). The results also showed that the Violet oil had the most effect among the three groups. In addition, it was more effective on sleep quality than sleep quantity. CONCLUSION Considering the effects of natural nasal drug on the improvement of sleep quality in insomniac patients, this study has proposed the use of Violet oil as a natural and herbal drug in a non-oral method without serious side effects for treatment of insomnia.

Abstract
Viola odorata as a medical herb is used in liver disorders and relieving cancer pain. In the present study, the cytotoxic, antioxidant, and anti-metastatic properties of Viola odorata hydro-alcoholic extract (VOE) were investigated in 4T1 breast cancer model. After treatment of 4T1 breast cancer cells with VOE, cell viability was measured by MTT assay. The implanted mice were treated with different concentration of VOE (50, 150 and 250 mg/kg) for 21 days. Levels of lactate dehydrogenase (LDH), γ -glutamyl transferase (GGT), alkaline phosphatase (ALP), carcinoembryonic antigen (CEA) and cancer antigen 15-3(CA15-3) in serum, and also catalase (CAT) and superoxide dismutase (SOD) activities in tumor tissue were measured. Metastatic rate was investigated in liver, spleen and lung tissues. VOE decreased cell viability of 4T1 cells, significantly. VOE significantly inhibited the cell proliferation, but not vasculature in the tumors that revealed by immunohistochemical analysis for Ki-67 and CD31 expression, respectively. VOE increased the Bax/Bcl-2 ratio in VOE250-treated group compared to control group. Serum analysis showed that treatment with 250 mg/kg of VOE significantly reduced LDH (not ALP and GGT) levels compared to controls. No linear correlation was found between the values of CEA and CA15-3 with tumor size. The rate of CAT activity was increased in VOE250-treated rats whereas, CAT and SOD activities were reduced in VOE50 group. VOE250 significantly decreased the metastatic rate in liver and lung compared to the other doses of VOE. Consequently, Viola odorata has cytotoxic effects on 4T1 cells and affects antioxidant activity and metastasis in breast cancer.

Abstract
Common violet (Viola odorata L., Violaceae) has shown various medical applications. Current study aimed to compile a review over chemical composition and medicinal properties of this plant in modern phytotherapy and its related multipotential products from traditional Persian medicine (TPM). Medicinal applications of V. odorata and respective products were derived from credible pharmaceutical textbooks of TPM (10th-18th century AD). In parallel, electronic databases including PubMed, Scopus, and ScienceDirect were explored for targeted purposes. Management of cough, fever, common cold, headache, insomnia, epilepsy, constipation, palpitation, dyspnea, dysuria, and skin diseases is of most applications of V. odorata, reported in TPM. On the other side, this herb plant has exerted antiinflammatory, analgesic, antioxidant, diuretic, antihypertensive, and antibacterial activities in modern phytotherapy. Violet TPM therapeutic preparations are including violet oil in the form of nasal or topical application for neurologic and skin disorders as well as pill, decoction, sweet syrup, and confection or semisolid oral preparations for skin, respiratory, gastrointestinal, and urinary ailments. Flavonoids, saponins, and alkaloids are responsible for pharmacological activities. Some medical applications of V. odorata in TPM have been proven by recent studies. However, more studies are needed to confirm these medicinal properties. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
Trichomonas vaginalis is a flagellated parasite affecting about 276 million people annually worldwide. Tricomoniasis is associated with different complications in pregnant women and infants. 5'-nitroimidazole derivatives (metronidazole, ornidazole, and tinidazole) are FDA approved drugs recommended for trichomoniasis treatment. Treatment with metronidazole 5'-nitroimidazole derivatives is associated with many side effects, and drug resistance to metronidazole has been reported in some cases. Recently, many attempts have been made to evaluate the effects of plants on causative agents of vaginal infections. In our research, the national and international databases were searched and the effects of various herbal extracts on T. vaginalis in Iran were reviewed from 2006 to 2016. In articles investigated, some plants had favorable antitrichomonal effects and needed to be further investigated. All the plant extracts have only been evaluated in vitro. Surveys of different articles in this review show that the active ingredients present in different parts of plants, including aerial parts, leaves, flowers, stems, and root can be suitable sources for introducing and developing new antitrichomonal compounds.

Abstract
Background As per the recent statistical reports of World Health Organisation (WHO), 13% of total global population is obese. Orlistat remains to be the only drug approved for the long term treatment of obesity. Recent findings highlighted severe adverse effects of orlistat that included hepatotoxicity, gall stones, kidney stones and acute pancreatitis. Therefore, search for new drug is required. The investigations based on endophytic natural products would prove pivotal in the global fight against this health issue. Methods Obesity is associated with lipid metabolism involving pancreatic lipase enzyme. The inhibition of pancreatic lipase is demonstrated by using the extracts of endophytes isolated from Viola odorata Linn. In addition, endophytes were identified using ITS based rDNA sequencing. Results Present study involves the isolation and identification of 27 endophytes from V. odorata. All the endophytes were evaluated for lipase inhibitory activities. The extracts of seven endophytes exhibited lipase inhibitory activity with IC50 < 10 μg/mL. The extract of VOLF4 (Aspergillus sp.) displayed promising lipase inhibitory activity (IC50 3.8 μg/mL). Conclusion The present study demonstrates that V. odorata harbors endophytic community with potent lipase inhibitory activity. VOLF4 is the potential endophyte. The extract of VOLF4 can be used to develop the potential drug to treat obesity.

Abstract
BACKGROUND A compound herbal formulation (POL4) has been used in the indigenous system of medicine to treat cardiometabolic disorders like diabetes and associated hypertension. POL4 and most of its constituents have not been studied widely for its therapeutic use in hypertension. This study is aimed to determine the efficacy and possible insight into mechanism(s) for the medicinal use of POL4 and its ingredients in hypertension. METHODS The aqueous methanolic extracts of POL4 (POL4.Cr) and its components [Cichorium intybus (Ci.Cr), Gymnema sylvestre (Gs.Cr), Nigella sativa (Ns.Cr) and Trigonella foenum graecum (Tfg.Cr)] were tested for blood pressure lowering activity in anaesthetized Sprague-Dawley rats. To assess the vasomodulatory effect, isolated tissue experiments were performed on rat aortic strips using isometric force transducer coupled with PowerLab data acquisition system. RESULTS Administration of POL4 to rats caused a dose-dependent (1-100 mg/kg) fall in mean arterial pressure (MAP) with maximum effect of 85.33 ± 1.76% at 100 mg/kg, similar to the effect of verapamil. All ingredients of POL4 also decreased blood pressure with varying efficacy in following order Ns.Cr ≅ Ci.Cr > Tfg.Cr > Gs.Cr. In rat aortic preparations, POL4 and its ingredients inhibited K+ (80 mM)-induced contractions, Ci.Cr was the most potent followed by Ns.Cr > Tfg.Cr > Gs.Cr ≅ POL4. Against phenylephrine (P.E) contractions, Ci.Cr and Tfg.Cr exhibited complete relaxation, while POL4.Cr, Gs.Cr and Ns.Cr showed vasomodulatory effect. The Ca++ antagonist activity was confirmed when POL4 and its ingredients shifted Ca++ concentrations-response curves to the right in a manner similar to that of verapamil. On baseline of rat aorta, the parent formulation and its ingredients (except Tfg.Cr) exhibited partially phentolamine (1 μM)-sensitive vasoconstriction. CONCLUSION These data show that POL4 and its constituents possess blood pressure lowering activity mediated through inhibition of Ca++ influx via membranous Ca++ channels and receptor (α-adrenergic) operated pathways. Thus, this study provides a rationale to the medicinal use of POL4 and its constituents in hypertension.

Abstract
STATEMENT OF THE PROBLEM Oral cancer is among the ten most common cancers worldwide. It affects the life quality of patients in many ways. PURPOSE The aim of this study was to compare the effects of two different systemic doses of Viola Odorata syrup on the prevention of 4-Nitroquinoline-1-oxide (4-NQO) induced tongue dysplasia in rats. MATERIALS AND METHOD Forty-eight male Wistar rats were divided into four groups of A, B, C and D. Group A served as the control group. The rats in groups B to D received 30 ppm of 4-NQO in drinking water for 12 weeks. Additionally, the rats in groups B and C received Viola Odorata syrup at doses of 15 and 5 ml/kg, respectively, 3 times a week. Body weights were measured three times a week. At the end, the rats were euthanized and the tongue was removed. Histological evaluations for carcinogenesis were carried out under a light microscope. RESULTS The mean body weight of the rats in groups B, C, and D were lower than that in group A (p< 0.01). After 12 weeks of treatment, microscopically no histological changes of the tongue base epithelia were observed in the control group. The rats in group B did not show severe dysplastic changes; only mild to moderate histological changes including hyperplasia and hyperkeratosis were evident. These incidences were significantly more apparent in groups C with moderate to severe changes (p< 0.05) and group D with severe dysplastic changes (p< 0.01). Almost all rats in group D had hyperplasia and manifested all of the stages of dysplasia. CONCLUSION Viola Odorata extract has dose-dependent inhibitory effects on the development of tongue induced dysplasia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Calpurnia aurea (Ait.) Benth. subsp. aurea (CASA) (Fabaceae) seeds are used to treat hypertension in Ethiopian folklore medicine, particularly by Shinasha, Agew-awi and Amhara people in northwest Ethiopia. However, the claim has so far not been substantiated scientifically. AIM OF THE STUDY The study was conducted to evaluate the antihypertensive activity of 80% methanol extract of CASA in animal model of hypertension as well as its vasorelaxant effect and possible underlying mechanisms in isolated guinea pig aorta. MATERIAL AND METHODS Hypotensive and antihypertensive effect of CASA extract was determined in vivo through the intravenous (iv) route in normotensive and hypertensive anesthetized rats using 2-kidney-1-clip (2K1C) rat model. Ex vivo, guinea pig thoracic aortic rings were isolated and suspended in organ bath, and the vasodepressor effects as well as the mechanism of action of the extract were studied by means of isometric tension recording experiments. RESULTS The blood pressure fell dose-dependently and significantly in renal hypertensive and normotensive rats following i.v. administration, suggesting that the hydroalcoholic extract possesses hypotensive and antihypertensive effects. The extract also caused a dose-dependent relaxation of aorta pre-contracted with KCl at a concentration of 5-250mg/L, with a maximum relaxation of 92.1% achieved at 250mg/L. The relaxation mechanism was found to be independent of the muscarinic receptors, histamine receptors, ATP dependent K(+) channels, cyclooxygenase enzymes, cGMP/NO pathway and the endothelium system. The extract caused rightward shift of the Ca(++) dose-response curves, similar to that caused by verapamil, indicating that it produced vasorelaxation by inhibiting extracellular Ca(2+) influx. CONCLUSIONS The findings demonstrate that the plant is endowed with antihypertensive effect, providing evidence for its traditional use. The effect may be, at least in part, due to dilation of blood vessels through blockage of Ca(2+) channels.

JOURNAL OF ETHNOPHARMACOLOGY 2016; 184:154-186. [PMID: 26947900 DOI: 10.1016/j.jep.2016.02.039] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/22/2015] [Revised: 02/25/2016] [Accepted: 02/27/2016] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE There is very limited information regarding medicinal plants used by traditional healers in Pakistan, for treating wide-ranging diseases. Current study provides significant ethnopharmacological information, both qualitative and quantitative on medical plants in Pakistan and the pharmacological importance of herbal drinks, especially in the discovery of new drugs. MATERIALS AND METHODS The current ethnomedicinal field study was conducted from various traditional communities of Pakistan to document usage of medicinal plants as herbal drinks. Data was collected through field interviews from local people and using semi-structured questionnaires. Data was analyzed using quantitative indices such as UV (use value), RFC (Relative frequency of citation), and FL (Fidelity level). RESULTS The present study recorded 217 plant species belonging to 174 genera and 69 families used in herbal drinks preparations. Major herbal preparations include decoctions, infusions and juice. According to use reports, significant species were Aloe vera, Artemisia fragrans, Allium cepa, Senegalia catechu, Alternanthera sessilis, Malva ludwigii, Arnebia benthamii, Cichorium intybus, Coccinia grandis, Dalbergia sissoo. Major ailment treated with herbal drinks include heartburn, fever, diarrhea, hypertension, and others. Use value (UV) varies from 0.23 to 0.02, with Mentha arvensis (0.23) having the highest value of UV followed by Mentha longifolia (0.22), Plantago lanceolate (0.19), Achillea millefolium (0.18), Coriandrum sativum (0.18), Justicia adhatoda and Malva sylvestris (0.17). Values of RFC varies from 0.28 to 0.09 while Fidelity level (FL) among plants varies from 37.5 to 100. Alternanthera sessilis, Oxytropis lapponica, Millettia pinnata and Salvia bucharica had the highest FL value (100). CONCLUSION The use of medicinal plants is prevalent in traditional communities of Pakistan. Different herbal preparations are in common practice including various herbal drinks a common tradition and much favoured herbal preparation in terms of its results and regarded as reciprocal to modern drugs. Therefore, suggesting further pharmacological, phytochemical evaluation for essential metabolites and chemical constituents.

Abstract
Traditional medicine has a history extending back to thousands of years, and during the intervening time, man has identified the healing properties of a very broad range of plants. Globally, the use of herbal therapies to treat and manage cardiovascular disease (CVD) is on the rise. This is the second part of our comprehensive review where we discuss the mechanisms of plants and herbs used for the treatment and management of high blood pressure. Similar to the first part, PubMed and ScienceDirect databases were utilized, and the following keywords and phrases were used as inclusion criteria: hypertension, high blood pressure, herbal medicine, complementary and alternative medicine, endothelial cells, nitric oxide (NO), vascular smooth muscle cell (VSMC) proliferation, hydrogen sulfide, nuclear factor kappa-B (NF-κB), oxidative stress, and epigenetics/epigenomics. Each of the aforementioned keywords was co-joined with plant or herb in question, and where possible with its constituent molecule(s). This part deals in particular with plants that are used, albeit less frequently, for the treatment and management of hypertension. We then discuss the interplay between herbs/prescription drugs and herbs/epigenetics in the context of this disease. The review then concludes with a recommendation for more rigorous, well-developed clinical trials to concretely determine the beneficial impact of herbs and plants on hypertension and a disease-free living.

Abstract
This study aimed to investigate the effect of violet syrup on cough alleviation in children with intermittent asthma. In a parallel, double-blind, randomized controlled trial, 182 children aged 2 to 12 years with intermittent asthma were randomly assigned 1:1 to receive violet syrup or placebo along with the common standard treatments in both groups (short-acting β-agonist). Both groups were evaluated in terms of the duration until cough suppression was achieved. No significant difference was observed in basic characteristics. The duration lasting to yield more than 50% cough reduction and 100% cough suppression was significantly less in the violet syrup group compared to placebo (P = .001, P < .001, respectively). There was no significant difference in therapeutic effects between boys and girls. There was a significant inverse correlation between the age of children and rate of cough alleviation and suppression by violet syrup. This study showed that the adjuvant use of violet syrup with short-acting β-agonist can enhance the cough suppression in children with intermittent asthma.

Abstract
Background Comparable to commercial expensive high-fat diets, cholesterol-cholate-butterfat (CCB) diet has also been used to induce hyperlipidemia in rats. Our objective was to explore its influence on multiple organs. Consequence of fasting was also analysed. Methods Rats in groups 1 and 2 received normal diet (ND) whereas groups 3 and 4 received CCB-diet. Food was withdrawn daily for two hours from groups 2 (ND-F) and 4 (CCB-F). Blood was collected at fourth and sixth week for biochemical estimation; Morris water maze was done in the sixth week for learning ability and memory; after which aortae were isolated for vascular reactivity. Results Apart from hyperlipidemia, CCB also induced hyperglycemia with marked increase in hepatic enzymes: gamma-glutamyl transferase (GGT), alanine and aspartate aminotransferase (ALT and AST); and vascular biomarkers: uric acid (UA), phosphorus and alkaline phosphatase (ALP). Isolated aortae, pre-contracted with phenylephrine, were less responsive to acetylcholine indicating endothelial dysfunction – serum nitric oxide (NO) production was limited with subsequent inhibition of endothelial NO synthase. CCB diet also compromised learning ability. CCB-coupled fasting potentiated hyperlipidemia but prevented memory-loss. Conclusion We introduce CCB-diet for multi-organ dysfunction in rats, and propose its use for research on cardiovascular diseases and associated manifestations involving immense interplay of integrated pathways.

Abstract
Background: Insomnia is the most common sleep disorder that reduces quality of life. Objectives: Due to side effects of hypnotic drug and the increasing demand for alternative medicine substitutes, violet oil (VO) was used in this study. VO is a known medication in Iranian traditional medicine that induces sleep in insomniac patients. Patients and Methods: This study was conducted as an experimental pretest-posttest evaluation on VO efficacy in 50 patients with chronic insomnia in Iranian Traditional Medicine Clinic of Mashhad University of Medical Sciences, Mashhad, Iran. Treatment consisted of intranasal drop of VO, two drops containing 66 mg of VO in each nostril nightly before sleeping for one month. All patients were asked to complete an Insomnia Severity Index (ISI) questionnaire before the start of the trial and after one month of treatment. Results: Improvements in sleep and ISI scores were significantly greater in patients after a month receiving VO drop in comparison with before starting treatment (P < 0.05). A few patients reported some complications about VO consumption, most of which were mild and no serious adverse event was encountered. Conclusions: VO can be presented as a safe, well-tolerated, and effective herbal preparation in patients with chronic insomnia.

Abstract
BACKGROUND Almonds are reported to be protective against cardiovascular diseases (CVDs); however, the possible mode of action has only infrequently been explored. OBJECTIVE This study aimed at investigating the mechanistic basis for the benefits of almonds in atherosclerotic CVDs. METHODS Three studies in 3 groups of rats were designed with the use of tyloxapol (study 1), a high-fat diet (HFD; study 2), and white-flour fructose (WFF; study 3). In each of the studies, the first group acted as the control [administered saline in study 1 and fed a normal diet (ND) in studies 2 and 3]; the second and third groups were treated with tyloxapol in study 1, an HFD in study 2, and WFF in study 3. The third group in each study was also fed almonds (3 g/kg) for 4 wk, after which blood was collected for biochemical evaluation. Livers and aortas were isolated from the rats in studies 1 and 2 for enzyme assays and vascular analysis, respectively. RESULTS Almond supplementation significantly (P < 0.05) prevented hyperlipidemia in all of the rat models. Supplementation suppressed cholesterol synthesis, leading to a 65% inhibition of tyloxapol-induced activation of hepatic β-hydroxy-β-methylglutaryl coenzyme A reductase. The almond intervention inhibited by 56% the HFD-induced increase in serum concentrations of hepatic aminotransferases. Almonds also protected against an HFD-induced increase in uric acid (0.9-fold), phosphorus (1.1-fold), alkaline phosphatase (4.6-fold), and γ-glutamyltransferase (1-fold), with resultant concentrations that were not different from those in ND-fed rats (P > 0.05). Almonds partially restored the vascular reactivity of isolated aortas and prevented HFD-induced endothelial dysfunction by reducing inhibition of endothelial nitric oxide (NO) synthase and promoting NO release. The 70% decrease in HDL cholesterol that was observed in the WFF group was prevented by almond supplementation; serum and LDL cholesterol were also normalized. CONCLUSIONS The inhibition of de novo cholesterol synthesis, prevention of hepatic damage, and restoration of vascular function via the protection of endothelium and influence on the NO pathway are some of the mechanisms underlying the medicinal value of almonds in CVDs.

Aziz N, Mehmood MH, Gilani AH. Studies on two polyherbal formulations (ZPTO and ZTO) for comparison of their antidyslipidemic, antihypertensive and endothelial modulating activities. Altern Ther Health Med 2013; 13:371. [PMID: 24370063 PMCID: PMC4029524 DOI: 10.1186/1472-6882-13-371] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2013] [Accepted: 12/17/2013] [Indexed: 11/21/2022]
Abstract
Background Cardiovascular disorders (CVDs) are the leading cause of disease burden worldwide. Apart from available synthetic drugs used in CVDs, there are many herbal formulations including POL-10 (containing 10 herbs), which have been shown to be effective in animal studies but POL-10 was found to cause tachycardia in rodents as its side effect. This study was designed to modify the composition of POL-10 for better efficacy and/or safety profile in CVDs. Methods To assess the antidyslipidemic, antihypertensive and endothelial modulatory properties of two herbal formulations, (ZPTO and ZTO) containing Z: Zingiber officinalis, P: Piper nigrum, T: Terminalia belerica and O: Orchis mascula, different animal models including, tyloxapol and high fat diet-induced dyslipidemia and spontaneously hypertensive rats (SHR) were used. Effect on endothelial function was studied using isolated tissue bath set up coupled with PowerLab data acquisition system. The antioxidant activity was carried out using DPPH radical-scavenging assay. Results Based on preliminary screening of the ingredients of POL-10 in tyloxapol-induced hyperlipidemic rats, ZPTO and ZTO containing four active ingredients namely; Z, P, T and O were identified for further studies and comparison. In tyloxapol-induced hyperlipidemic rats, both ZPTO and ZTO caused significant reduction in serum triglyceride (TG) and total cholesterol (TC). In high fat diet-fed rats, ZPTO decreased TC, low-density lipoproteins cholesterol (LDL-C) and atherogenic index (AI). ZTO also showed similar effects to those of ZPTO with additional merits being more effective in reducing AI, body weight and more importantly raising high-density lipoproteins. In SHR, both formulations markedly reduced systolic blood pressure, AI and TG levels, ZTO being more potent in reversing endothelial dysfunction while was devoid of cardiac stimulatory effect. In addition, ZTO also reduced LDL-C and improved glucose levels in SHR. In DPPH radical-scavenging activity test, ZTO was also more potent than ZPTO. Conclusion The modified formulation, ZTO was not only found more effective in correcting cardiovascular abnormalities than ZPTO or POL-10 but also it was free from tachycardiac side-effect, which might be observed because of the presence of Piper nigrum in ZPTO.
