Dental applications of Punica granatum L. in the treatment of gingivitis: A review of ethnomedicinal uses, randomized clinical trials, and antibacterial potential against Porphyromonas gingivalis

ETHNOPHARMACOLOGICAL RELEVANCE

Mouthwashes based on medicinal plants have demonstrated benefits in controlling plaque and inflammation, acting positively on the oral hygiene of patients with gingivitis. In traditional medicine, Punica granatum L. has been used to treat oral diseases in countries in Europe, Asia, North America, and Africa.

AIM OF THE STUDY

The present study aimed to conduct a comprehensive review on the dental applications of Punica granatum L. for the treatment of gingivitis, including ethnomedicinal uses, analysis of randomized clinical trials, antibacterial activity against Porphyromonas gingivalis, mechanisms of action of phytochemicals isolated from this plant, and preclinical toxicity.

MATERIALS AND METHODS

The literature was retrieved from Google Scholar, PubMed®, SciELO, and ScienceDirect®, since the first report published on the topic in 2001 until March 2024.

RESULTS

Several clinical trials have demonstrated that mouthwashes containing P. granatum have equal or better efficacy than chlorhexidine in treating patients with gingivitis, confirming the indications for use of this plant by traditional communities. However, reports on the in vitro antibacterial activity of extracts from the fruits of this plant have not shown clinical relevance against the pathogen P. gingivalis. The ellagitannin punicalagin isolated from P. granatum has shown potential against several strains of Gram-positive and Gram-negative bacteria, but, to date, this compound has not yet been tested against P. gingivalis. It is likely that the mechanisms of action of flavonoids, such as quercetin, are involved in the inhibition of the activities of the RgpA, RgpB, and Kgp proteases of P. gingivalis.

CONCLUSIONS

In summary, natural products obtained from P. granatum do not present toxic side effects and can be considered as possible substitutes of commercial products recommended for the treatment of gingivitis and other oral diseases.

Folk Knowledge and Perceptions about the Use of Wild Fruits and Vegetables-Cross-Cultural Knowledge in the Pipli Pahar Reserved Forest of Okara, Pakistan

Wild fruits and vegetables (WFVs) have been vital to local communities for centuries and make an important contribution to daily life and income. However, traditional knowledge of the use of wild fruits is at risk of being lost due to inadequate documentation. This study aimed to secure this knowledge through intermittent field visits and a semi-structured questionnaire. Using various ethnobotanical data analysis tools and SPSS (IBM 25), this study identified 65 WFV species (52 genera and 29 families). These species, mostly consumed as vegetables (49%) or fruits (43%), were predominantly herbaceous (48%) in wild and semi-wild habitats (67%). 20 WFVs were known to local communities (highest RFC), Phoenix sylvestris stood out as the most utilized species (highest UV). Surprisingly, only 23% of the WFVs were sold at markets. The survey identified 21 unique WFVs that are rarely documented for human consumption in Pakistan (e.g., Ehretia obtusifolia, Euploca strigosa, Brassica juncea, Cleome brachycarpa, Gymnosporia royleana, Cucumis maderaspatanus, Croton bonplandianus, Euphorbia prostrata, Vachellia nilotica, Pongamia pinnata, Grewia asiatica, Malvastrum coromandelianum, Morus serrata, Argemone mexicana, Bambusa vulgaris, Echinochloa colonum, Solanum virginianum, Physalis angulata, Withania somnifera, Zygophyllum creticum, and Peganum harmala), as well as 14 novel uses and five novel edible parts. Despite their ecological importance, the use of WFVs has declined because local people are unaware of their cultural and economic value. Preservation of traditional knowledge through education on conservation and utilization could boost economies and livelihoods in this and similar areas worldwide.

Medicinal plants used in the management of cancers by residents in the Elgon Sub-Region, Uganda

BACKGROUND

In Uganda, medicinal plants have been utilized to treat a variety of ailments, including cancer. However, there is little information available about the medicinal plants used to treat cancer in the Elgon subregion. As a result, the current study documented the plant species used in the management of cancer in the Elgon sub-region.

METHODS

Data were gathered by observation, self-administered questionnaires, interview guides, and guided field trips. Analyzing descriptive statistics and creating graphs were done using SPSS (version 21.0) and GraphPad Prism® version 9.0.0, respectively. Well-established formulae were used to calculate quantitative indices. The narratives were interpreted using major theories and hypotheses in ethnobotany.

RESULTS

A total of 50 plant species from 36 families were documented, and herbal knowledge was mainly acquired through inheritance. Fabaceae and Asteraceae comprised more plant species used in herbal preparation. Most plants were collected from forest reserves (63%); herbal therapies were made from herbs (45%); and leaves were primarily decocted (43%). The most frequently used plants were Tylosema fassoglensis, Hydnora abyssinica, Azidarachata indica, Prunus Africana, Kigelia africana, Syzygium cumini, Hydnora africana, Rhoicissus tridentata, Albizia coriaria, and Plectranthus cuanneus. All the most commonly used plants exhibited a high preference ranking (60-86%) and reliability level (74.1-93.9%). Generally, the ICF for all the cancers treated by medicinal plants was close to 1 (0.84-0.95).

CONCLUSIONS

The ten most commonly utilized plants were favored, dependable, and most important for treating all known cancers. As a result, more investigation is required to determine their phytochemistry, toxicity, and effectiveness in both in vivo and in vitro studies. This could be a cornerstone for the pharmaceutical sector to develop new anticancer medications.

The local medicinal plant knowledge in Kashmir Western Himalaya: a way to foster ecological transition via community-centred health seeking strategies

BACKGROUND

The mountainous region of Kashmir is a biodiversity hotspot, with diverse local communities and a rich cultural history linked to nature. Mountain ecosystems are highly vulnerable to climate change. This study emphasises the need to record the indigenous ethnoecological knowledge of wild plants used for the treatment of various ailments at higher elevations in remote areas where globalisation poses a threat to this traditional knowledge.

METHODS

The field survey was carried out in 2020-2022, to collect data on wild medicinal plants. Informants were selected randomly to collect indigenous medicinal knowledge using semi-structured interviews and group discussions. Various quantitative indices were employed to evaluate ethnomedicinal data.

RESULTS

A total of 110 medicinal plants belonging to 49 families were recorded in the study area. These medicinal plants are extensively used by local communities for the treatment of 20 major disease categories. Asteraceae was the dominant family contributing (9.09%) to medicinal plants, followed by Polygonaceae (8.18%), Apiaceae (7.27%), Lamiaceae (5.45%), and Ranunculaceae (5.45%). We observed 166 remedies were used for the treatment of various diseases in humans, and 9 remedies were used for animals. The most frequently used medicinal remedy was tea or decoction (30.91%). Among the medicinal plants, herbs (85.5%) were most frequently used by the local populations of Kashmir, whereas leaves (10.26%) were used for the treatment of various ailments. Out of 110 species, 31 were endemic, 15 of which are endemic to the Kashmir region and 16 to the Western Himalaya. The highest RFC value was reported for Allium humile (0.77), the highest UV value for Fritillaria cirrhosa (1.33), and the highest ICF value for gastro-intestinal/digestive disorders (0.85).

CONCLUSIONS

Local communities still rely on wild medicinal plants for primary healthcare. These communities retained valuable indigenous knowledge, which needs to be preserved for the conservation and sustainable utilisation of natural resources. Further field exploration is required to fully explore indigenous knowledge in the mountainous regions of Kashmir, and this knowledge has the potential to support the ongoing ecological transition.

Ethnobotanical Insights into Medicinal and Culinary Plant Use: The Dwindling Traditional Heritage of the Dard Ethnic Group in the Gurez Region of the Kashmir Valley, India

This ethnobiological study addresses the complicated relationship between the Dard ethnic group and their natural environment in the Gurez region of the Kashmir Valley. The study documents their traditional knowledge of the use of plant species for medicinal and culinary purposes. A total of 87 plant species from 41 different families were cataloged, with the Asteraceae family (15 species) and the Lamiaceae family (12 species) being the most commonly used. These plants were found to be used to treat 20 different ailments, with menstrual cramps being the most common (12 species). The fidelity values for these plants ranged from 11.10 to 71.42, demonstrating their importance in traditional medicine. In addition, 17 plant species were found to be useful for gastronomic purposes, with Juglans regia being the most valuable (use value of 0.73). The study also evaluated the conservation status of these plants and found that seven of them are considered critically endangered, ten endangered, and four endangered according to the IUCN classification. This study offers insights into the Dard people's deep connection to their natural environment and has significant implications for policy formulation, cultural conservation, and sustainable use of endemic species, as well as potential applications in pharmaceutical research for therapeutic compounds.

A cross-cultural study of high-altitude botanical resources among diverse ethnic groups in Kashmir Himalaya, India

BACKGROUND

In the Himalayas, traditional knowledge and biodiversity are strongly linked due to the symbiotic interaction between plant and cultural diversity, as well as the support provided by cultural memories, ecological awareness, and social norms. Our study was focused on documenting the vanishing knowledge in the Kashmir Himalaya with the following main objectives: 1) to document the ethnomedical and cultural knowledge of the local flora, 2) to evaluate the cross-cultural use of the flora in the region, and, finally, 3) to identify the key indicator species utilized by each ethnic group using multivariate statistical analysis.

METHODS

We used semi-structured questionnaires to conduct interviews with people of different ethnicity, gender, age, and occupational categories. The intercultural relationships of species utilization among ethnic groups were examined using a Venn diagram. The overall trends between the indicator values and the plant species used by diverse ethnic groups were illustrated using the linear regression model.

RESULTS

We recorded 46 species belonging to 25 different families used by the local people of the Kashmir Valley belonging to four ethnic groups (Gujjar, Bakarwal, Pahari, and Kashmiri). The dominant families recorded were Asteraceae and Ranunculaceae followed by Caprifoliaceae. Rhizomes were the most utilized plant part, followed by leaves. A total of 33 ailments were treated with plants, and gastrointestinal disorders were treated with most species followed by musculoskeletal diseases and dermatological problems. Across cultural relationships, the Gujjar and Pahari showed greater similarity (17%). This may be due to the fact that both ethnic groups share a common geographical landscape and are exogamous to each other. We identified key indicator species used by different ethnic groups with significant (p ≤ 0.05) values. For instance, in the Gujjar ethnic group, Aconitum heterophyllum and Phytolacca acinosa had significant indicator value, which was due to the fact that these plants were easily accessible and also had a wide range of uses. In contrast, the Bakarwal ethnic group showed different indicator species, with Rheum spiciforme and Rhododendron campanulatum being highly significant (p ≤ 0.05), because this ethnic group spends the majority of their time in high-altitude pastures, using a particularly wide variety of plant species for medicine, food, and fuelwood. While indicator values and plant usage were positively correlated for the Gujjar, Kashmiri, and Pahari ethnic groups, they were negatively correlated for the Bakarwal. The positive correlation indicates cultural preferences for certain plant use and underlines the cultural significance of each species. The current study reported new uses for the following species: raw roots of Jurinea dolomiaea used for tooth cleaning, seeds of Verbascum thapsus applied for respiratory diseases, and flowers of Saussurea simpsoniana given to anyone as a good luck wish.

CONCLUSION

The current study highlights historical ethnic group stratifications and cultural standing while comparing reported taxa across cultures. Each ethnic group made extensive ethnomedical use of plants, and knowledge, originally transmitted verbally, is now available in writing for reference. This could pave the way for providing incentives to local communities to showcase their talents, celebrate them, and gain from potential development initiatives.

An ethnomedicinal study in tulo district, west hararghe zone, oromia region, Ethiopia

Traditional medicinal plants used by local Oromo people of Tulo District in west Hararghe, Ethiopia, were investigated before people's medicinal knowledge vanishes. Data on medicinal plants and demography were obtained between November 2019 and October 2020 through semi-structured interviews, group discussion and direct guided onsite observation to elicit information from 376 non-traditional and 20 traditional medicine practitioners. Ethnobotanical indices including informant consensus factor (ICF), preference ranking (PR), fidelity level (FL), relative frequency of citation (RFG) and cultural importance (CI) were employed for the data analysis. Moreover; descriptive statistics, t-test, analysis of variance and linear regression were used to reveal the effects of socio-demographic factors on respondents' traditional medicinal knowledge. Totally 104 plants distributed among 98 genera and 55 families were enumerated for the treatment of 60 illnesses. Seventy-seven of these medicinal plants serve to treat human ailments, whereas 11 and 16 of them were used for livestock and for both, respectively. Asteraceae and Lamiaceae were species rich families. Leaves were the most frequently (41.53%) reported structures for the preparation of remedies. Crushing was the principal approach (34.50%) of remedy preparation. Oral administration was frequently (66.08%) used route of application. The highest ICF was observed for swelling and hemorrhoid (0.90) category. Metabolic and degenerative as well as other ailment categories had the least ICF values. About 66% of medicinal plants had FL value of 100%. In PR, G. abyssinica was ranked first to treat cough. RFC values varied from 0.03 to 0.18 with the highest record for Salvia nilotica (0.18) followed by Lepidium sativum, Rydingia integrifolia and Nigella sativa each with 0.16; Euphorbia abyssinica and Asplenium monanthes each with 0.15. Extensive use of land for agricultural purpose was key threat to medicinal plant of Tulo District. All the tested socio-demographic features except religion significantly (P < 0.05) affected the traditional knowledge on medicinal plants possessed by the study population. The results of this study reveals that the people of Tulo District rely on traditional medicine of plant origin, and their indigenous knowledge is instrumental to exploit the most potential plants for further validation. Therefore, the medicinal plant species wealth of the study site and the associated indigenous knowledge need to be preserved.

Antidiarrheal Potential of Viola canescens: In Vivo and In Silico Approaches

Viola canescens Wall. is an important medicinal plant with reported therapeutic benefits. The current work sought to investigate the antidiarrheal properties of V. canescens extracts both in vivo and in silico. This study applied molecular docking to unravel the molecular mechanism of V. canescens and to find the most effective phytocompounds with antidiarrheal effects. The antidiarrheal activity of V. canescens was assessed utilizing the castor oil-induced diarrhea assay and the charcoal meal assay. Antidiarrheal characteristics were evaluated by measuring parameters such as intestinal motility, fecal score, and hypersecretion. The V. canescens extract had a dose-dependent and statistically significant impact in the charcoal meal assay and castor oil-induced diarrhea assay. In the castor oil-induced diarrhea assay, the ethyl acetate fraction (65.96%) showed the highest percentage of defecation inhibition at the highest dose (300 mg/kg (bw)), followed by the uncorrected crystalline compound (63.83%), crude alkaloids (63.83%), chloroform fraction (63.83%), and crude flavonoids (55.32%), while the aqueous fraction (40.43%) and n-Hexane fraction (42.55%) revealed the lowest antidiarrheal potential. In addition, the molecular docking investigation showed emetine, quercetin, and violanthin, isolated chemicals of V. canescens, to have the highest binding affinity to the target μ and δ opioid receptors with significant inhibitory capacity. These pharmacologically active metabolites in V. canescens were effective in treating diarrhea. This study lends credence to the traditional usage of V. canescens in treating gastrointestinal disorders.

Ethnobotanical study of medicinal plants of Pashat Valley, Bajaur, along Pakistan–Afghanistan border: a mountainous region of the Hindu Kush Range

Medicinal plants are the primary and effective source to cure various human ailments throughout the globe. The remote area of the Pashat valley at the Pakistan–Afghanistan border is still unexplored to document ethnomedicinal knowledge and practices. In the current study, the contemporary investigation recorded the native acquaintance of remedial plants. A total of 73 plant species belonging to 68 genera and 46 families were used by traditional communities for the treatment of 40 different kinds of human diseases including digestive, respiratory, urinary, skeletal, muscular systems, etc. The family Lamiaceae was found dominant with 9 species followed by Leguminosae and Solanaceae with 4 species each, Euphorbiaceae, Moraceae, Rhamnaceae and Rosaceae with three species each. The most frequently used parts of plants were leaves (35.7%) followed by fruits (22.4%), seeds (12.2%), roots (7.14%) and plants as a whole (6.12%). Whereas the remedy preparation approaches were in powder form (28.46%), decoction (26.15%), extract (20%) and a paste (11.54%). The quantitative ethnobotanical indices i.e. used value (UV), relative frequency citation (RFC), family importance value (FIV) and Jaccard index (JI) were calculated for all plant species. The used value (UV = 0.04) was found highest for Berberis lyceum, Myrtus communis, Punica granatum and Dodonea viscosa. Similarly, the maximum RFC value of 0.25 was investigated for Foeniculum vulgare and Olea ferruginea each. Besides, the highest FIV of 96.08% and 58.17% values were calculated for the family Lamiaceae and Solanaceae. This study shows that the corresponding area is rich in medicinal plants and could contribute to ethnomedicinal knowledge. The collected data will establish a baseline for the comprehensive investigation of active molecular constituents of the medicinal flora of the area. Soon, the exploration of these medicinal plants could discover new herbal drugs in the field of pharmacology.

Medicinal waterbirds in the traditional healthcare system: an assessment of biodiversity-cultural linkages in Eastern Khyber Pakhtunkhwa, Pakistan

BACKGROUND

Eastern Khyber Pakhtunkhwa is home to a vast range of medicinal and edible waterbird species due to its diverse geographical environment. Waterbird species have been used for various ailments and cultural practices since ancient times, while ethno-pharmacological applications and cultural uses of waterbird species in this area have seldom been documented. This study is the first ethnomedicinal and cultural assessment of waterbird species, and the first compilation and listing of all known data on these species in Eastern Khyber Pakhtunkhwa, Pakistan.

METHODS

Interviews and questionnaires were used to collect data from native respondents (N = 100). To analyze the data, principal component analysis (PCA), relative frequency of citation (RFC), fidelity level (FL%), relative popularity level (RPL), rank order priority, and similarity index were used.

RESULTS

In total, 64 waterbird species were utilized in cultural practices, of which 40 species are used to cure different infectious and chronic diseases such as cold, cough, flu, fever, respiratory disorders, asthma, TB, gastric ulcers, kidney stones, male impotency, obesity, paralysis, piles, cancer, arthritis, body pain, and weakness. PCA showed significant differences in the use of waterbird species among the local inhabitants of the study area, separated along the axis-2 (p < 0.05). The FL% of waterbird species varied from 12 to 100%. 100% FL was analyzed for four waterbird species, i.e., Charadrius mongolus (cold), Gallicrex cinerea (asthma), Anas platyrhynchos (cancer), and Esacus recurvirostris (body weakness). In this study, Mallard (Anas platyrhynchos) was the most popular species used in the healthcare system of Eastern Khyber Pakhtunkhwa, with high RFC (4.06), FL% (100), and RPL (1.0) values.

CONCLUSION

We concluded that waterbird species are more used for medicine and food purposes in the study area. However, in vitro/in vivo assessment of biochemical activities of waterbird species with a maximum FL% might be significant to produce novel drugs. Recent research shows important ethno-ornithological information about native people and their links with waterbird species, which might be helpful for the sustainable use of waterbird diversity in the research area.

Ethnobotanical study of Mandi Ahmad Abad, District Okara, Pakistan

This study hypothesized that native people have unique traditional knowledge of plant resources in the rural areas and basic objective was the documentation of this valuable inheritance. Ethnobotanical data was collected from a remote rural area of Mandi Ahmad Abad, Union council number NA-144 Tehsil Depalpur District Okara, Pakistan. A total of 94 informants were randomly interviewed to collect data about local names of plant species, mode of administration, recipes and ailments, and ethnobotanical uses through semi-structured questionnaire, interviews and group discussion methods. The collected data was statistically analyzed by calculating use value (UV), frequency of citation (FC), relative frequency of citation (RFC), factor of informant consensus (FIC), family importance value, and relative importance (RI). This study is also compared with ethnobotanical literature by using Jaccard’s index (JI) for similarity analysis. A total of 126 species belonging to 52 families were documented. The Poaceae (13spp.), Leguminosae (12spp.), Solanaceae (10spp.) and Cucurbitaceae (10spp.) were dominant families. Highest used value (UV = 0.22) was obtained for Azadirachta indica. The minimum used value (UV) was showed by Alhagi maurorum, Eclipta prostrata, Hibiscus rosa-sinensis, Solanum virginianum and Trianthema potulacastrum (UV = 0.01). Hepatitis, stomach ulcer, bowel disorders, urinary problems, psoriasis, cancer, and leucoderma were the most treated ailments with ICF value of 1, followed by leucorrhea (ICF: 0.89), and vomiting (ICF: 0.86). The highest Jaccard’s similarity index value (JI = 0.329) showed that plant species reported in our study was more similar with Arid regions of Northern Punjab, Pakistan. This novel ethnobotanical report concluded that traditional knowledge about use of medicinal plants is decreasing due to allopathic medicines. Immediate steps should be taken for conservation and documentation of traditional knowledge of plants especially those having medicinal properties.

Chemical profiling of Justicia vahlii Roth. (Acanthaceae) using UPLC-QTOF-MS and GC-MS analysis and evaluation of acute oral toxicity, antineuropathic and antioxidant activities

ETHNOPHARMACOLOGICAL RELEVANCE

Justicia vahlii Roth. (Acanthaceae), also called as kodasoori and bhekkar is an annual therophyte erect or decumbent herb used traditionally in toothache, skin diseases (itching, topical inflammation) and for the treatment of various respiratory disorders.

AIM OF THE STUDY

The current study aimed at exploring pain cessation potential of J. vahlii Roth. via murine model of neuropathic pain and its phytochemical, toxicological and antioxidant profiles.

MATERIALS AND METHODS

The hydro-alcoholic extract of J. vahlii (HAEJv) prepared by maceration technique was subjected to preliminary phytochemical screening, total bioactive content determination, UPLC-QTOF-MS and GC-MS analysis. Toxicity assessment was carried out by using brine shrimp lethality assay and acute oral toxicity test. Murine model of neuropathic pain was applied to assess the antineuropathic potential of the species. Furthermore effect of the extract on catalase, superoxide oxide dismutase (SOD), Glutathione (GSH), interleukin-1beta (IL-1β) and total necrosis factor-alpha (TNF-α) was also studied. In vitro antioxidant profile was explored by using four methods; 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azinobis(3-ethylbenothiazoline)-6-sulfonic acid (ABTS), CUPric reducing antioxidant capacity (CUPRAC) and Ferric reducing antioxidant power (FRAP) assay.

RESULTS

The phytochemical screening revealed the presence of phenols, flavonoids, coumarins, alkaloids and lignans as the major classes of secondary metabolites. The extract was found rich in total phenolics content (TPC) and total flavonoids content (TFC) with identification of total 59 bioactives in UPLC-QTOF-MS and 40 compounds in GC-MS analysis. The extract was found nontoxic up to 4000 mg/kg (p.o.) in mice and no mortality observed in brine shrimp lethality assay. The HAEJv significantly reduced number of acetic acid induced abdominal constrictions at 100 mg/kg (p < 0.01) and 200 mg/kg (p < 0.001) and increased paw withdrawal threshold p < 0.05 at 100 mg/kg and p < 0.001 at 200 mg/kg, and an increase in tail withdrawal latency time p < 0.001 at 200 mg/kg was observed. The extract significantly increased levels of catalase, SOD and GSH while decreased IL-1β and TNF-α levels in sciatic nerve tissue of mice. HAEJv showed highest antioxidant activity through CUPRAC method 121.32 ± 1.22 mg trolox equivalent per gram of dry extract (mg TE/g DE) followed by DPPH 81.334 ± 4.35 mg TE/g DE, FRAP 69.89 ± 3.05 mg TE/g DE and ABTS 38.17 ± 2.12 mg TE/g DE.

CONCLUSION

The current study back the traditional use of J. vahlii in pain cessation through antioxidant based antineuropathic pain activity and revealed the extract non-toxic with number of functional phytoconstituents and warrants further research on isolation of the compounds and sub-acute toxicity studies.

An ethnomedicinal expedition was conducted to collect and record indigenous knowledge about the use of medicinal plants by local inhabitants of four villages (Chittra, Topi, Pandi, and Kalri) of district Bagh, Azad Jammu and Kashmir. Ethnomedicinal data were obtained from 60 randomly selected local inhabitants of the study area through semi-structured questionnaires and interviews. These data were analyzed quantitatively through different ethnobotanical indices including family importance value, relative frequency of citation, use value (UV), fidelity level (FL), informant consensus factor (ICF), and Jaccard index (JI). our study reported 69 medicinal plants belonging to 39 families. Rosaceae (9 species) was a dominant family of the study area. Herb (54.83%) was dominant growth form of plants used for medicinal purpose. Leaves contributed maximum usage (44.29%) for curing diseases. Decoction (23 records) was most used mode of utilization. Relative frequency of citation and UV ranged from 0.03–0.85 and 0.05–1.17, respectively. There were 4 plant species with 100% FL. Highest ICF (0.88%) was found for gastrointestinal diseases. By comparing results with previous study, JI ranged from 0.54 to 24.43%. Our results found that there were 18 plant species not reported with ethnomedicinal aspect in previous studies from district Bagh region. The research of this study concludes that the area is rich with medicinal plants and the local inhabitant of this area still prefer medicinal plants over allopathic medicines for treating different ailments. Comparative analysis has shown some novel uses of plant species which may be due to cultural differences of the study area. However, awareness and pharmacological study are needed to conserve and unveil pharmaceutically important plants.

Indigenous knowledge and quantitative ethnobotany of the Tanawal area, Lesser Western Himalayas, Pakistan

Ethnobotanical field surveys were carried out in the Tanawal area of the Lesser Himalayan Region, Khyber Pakhtunkhawa, Province from April 2016 to October 2017. The area is located between 34.36 (34° 21' 30 N) latitude and 73.07 (73° 4' 0 E) longitude with an average elevation of 1374 meters above sea level. Ethnomedicinal data were collected through Participatory Rural Appraisal (PRA), and participants were selected through the snow-boll technique. Semi-structured, in-depth and open-ended interviews were conducted. The data were quantitatively evaluated using ethnomedicinal indices i.e. Relative frequency of citation (RFCs), Fidelity level (FL), and Use Value (UV). The ethnobotanical data were also comparatively analyzed through the Jaccard Index (JI). The study yielded 66 medicinal plants in 62 genera and 43 families. Asteraceae and Solanaceae were the most important families with five medicinal taxa each. Regarding medicinal plant part utilization, leaves (43.28%) were used predominantly, followed by whole plant (14.92%) and fruits (14.92%). Decoction was the main drug formulation applied to 21 species (31.15%) and the oral route was most common (56.1%) while 31.2% of medicinal plants were used for both oral and topical applications. Fifty health disorders were recorded and grouped in 15 categories. Maximum species were used to treat gastrointestinal disorders i.e. 13 species, dermal problems (12 species), and respiratory tract ailments (9). The calculated RFCs ranged between 81 to 31. The most important medicinal plants were Acacia modesta, Citrullus vulgaris, Tamarindus indica, and Momordica charantia with an RGFC of 81 each. The UV ranged between 0.58 and 3.6. Medicinal taxa with the highest UV were Dioscorea deltoidea (3.6), Withania coagulans (3.3), Momordica charantia (3.5), Silybum marianum and Pyrus pashia (3.2). FL values showed that 28 (41.79%) species had a FL value below 50 (74.62%) while 39 (58.20%) had higher FL values. Momordica charantia, Tamarindus indica, Acacia modesta and Citrullus vulgaris were 95.2 each. The Jaccard Index (JI) values ranged from16.77 to 0.98. The current study also reported 16 medicinal plants, commonly used around the globe, have been rarely documented for their medicinal values in the local ethnomedicinal literature i.e. Althaea officinalis, Plantanus orientalis, Jasminum sombac, Maytenus royleana, Cucurbita maxima, Phyllanthus emblica, Citrullus vulgaris. Polygonatum verticilliatum, Caseria tomentosa, Cistanche tubulosa, Bambusa arundinacea, Schinus molle, Tamarindus indica, Pongamia pinnata, Citrus limon and Catharanthus roseus. However, 48 medicinal plants had been reported in the literature but the current study reported their novel medicinal uses. Important taxa should be established in botanical gardens for in-situ conservation, chemical investigation and sustainable utilization. It would also be effective to improve the livelihoods of the local population.

Ethnobotany of the Himalayas: Safeguarding Medical Practices and Traditional Uses of Kashmir Regions

The present study was carried out to enlist the medicinal plants used by the local inhabitants of developing countries such as India, and the district of Kupwara of the Kashmir Himalaya has been targeted. Our research is one of the first study focusing on the statistical evaluation of the cross-cultural analysis between three different communities i.e., Dard, Kashmiri and Gujjar, of the study area. Sampling was carried out in eight villages in 2017 to 2020, and data were collected from 102 informants based on walking transects, to collect plant specimens, and semi-structured interviews. The medical usages of all collected taxa were grouped into 15 disease categories and 81 biomedical ailments. In this study, we documented around 107 plant taxa belonging to 52 families from the local inhabitants of the Kashmir Himalaya, which regulate the livelihood of the people and support cultural ecosystem services. Asteraceae, Rosaceae, Lamiaceae, Malvaceae, Ranunculaceae, Poaceae, Solanaceae, Polygonaceae, Plantaginaceae and Brassicaceae are the top most dominant families. Herbaceous groups of plants were more common than trees and shrubs, and 71.96% of herb taxa were employed as medicine. Liliaceae, Caprifoliaceae and Portulacaceae (FUV = 0.24 each) have the highest family use value (FUV). The most prominent family was Asteraceae (seven genera, nine taxa), followed by Rosaceae and Lamiaceae (six genera, six taxa each). Persicaria Mill., Rheum L., Aconitum L. and Artemisia L. were prominent genera. Valeriana jatamansi Jones ex Roxb. (47UR), Fritillaria cirrhosa D. Don (45UR), Arisaema jacquemontii Blume (37UR), Asparagus racemosus Willd. (36UR) and Rumex acetosa L. (35UR) were the most important plant taxa with reference to use-reports. The ethnomedicinal applications of Aesculus indica Wall. ex Cambess., Solanum pseudocapsicum L., Ranunculus hirtellus Royle and Cormus domestica (L.) Spach plant taxa are reported here for the first time from the Himalayan Kashmiri people. We recommend further research on ethnopharmacological application of these newly recorded ethnobotanical plants. The medical usage of the plant was limited to different parts of the plant. In terms of the usage percentage, whole plant (26.17%), leaves (24.30%) and roots (19.63%) were found to have the highest utilization. The powder form (40.19%) was the most frequently employed method of drug/medicine preparation, followed by the utilization of extracted juice and/or other extracts (22.43%). The ICF values range from 0.85 to 1.00. Their use to remedy parasitic problems (PAR) and insect bites (IB) (ICF = 1.0 each) had the maximum consensus mentioned by the informants, although the number of taxa employed under this category was very limited. The different plant taxa used for the treatment of the gastrointestinal problems (GAS) was the most prominent disease category (262 URs, 16.19%, 25 taxa, ICF = 0.90). About 65% of the plant taxa studied is indigenous to the Asia or Himalayan regions, and around 35% is found to be exotic in nature. A strong positive correlation was found between age, gender, educational qualification and medicinal plant knowledge. No significant association was between people of different communities interviewed in terms of medical knowledge of the plants, p = 0.347 (>0.05) and χ2 = 2.120. No significant difference was found between the number of species documented concerning gender as p = 0.347 (>0.05) and χ2 =0.885. This study provides the comprehensive status of ethnomedicinal knowledge among three different communities of the study area. This study provided an impetus in discovering the baseline primary data for molecules which would help in drug discovery and management of various diseases, apart from conserving the genepool of plants in the investigated area.

The Ethnobotany and Chemistry of South African Meliaceae: A Review

Meliaceae are widely distributed across the world in tropical or subtropical climates and are of considerable ethnobotanical importance as sources of traditional medicine and cosmetics. This comprehensive review summarizes the ethnobotanical uses and chemistry of 12 South African species, belonging to six genera: Ekebergia, Nymania, Entandrophragma, Pseudobersama, Trichilia, and Turraea. Eight of the species have ethnomedicinal records, classified into 17 major disease categories. The ethnomedicinal uses comprise 85 ailments dominated by gastrointestinal complaints, followed by gynaecological and obstetrics related problems. Chemical records were found for 10 species, which describe nine classes of compounds. In nearly all South African Meliaceae, limonoids are the predominant constituents while triterpenes, sterols, and coumarins are also common. The widest range of use-records and medicinal applications are found with the two most chemically diverse species, Ekebergiacapensis and Trichiliaemetica. Of the chemical compounds identified in the various plant organs of the 10 species of South African Meliaceae for which data are available, 42% was found in bark and 17% in seeds. Roots represent 35% and bark 33% of the organs that are used medicinally, and they are typically prepared as decoctions or infusions. Root and bark harvesting are destructive so that it may be important to examine the chemistry of plant parts such as wild-crafted leaves and fruits.

Which Plants for What Ailments: A Quantitative Analysis of Medicinal Ethnobotany of Ile-Ife, Osun State, Southwestern Nigeria

Studies on medicinal ethnobotany in rural areas and communities are important for documentation and generation of indigenous knowledge on the medicinal use of plants, as well as identification of new botanicals of pharmacological significance. This paper presents, for the first time, the quantitative ethnobotanical uses of medicinal plants in Ile-Ife, Osun State, Nigeria. The ethnobotanical survey was carried out by conducting semistructured interviews with 70 informants/collaborators. Data were analyzed using various quantitative indices, namely, Ethnobotanical Knowledge Index (EKI), Species Popularity Index (SPI), Relative Frequency of Citation (RFC), Cultural Importance Index (CII), Informant Consensus Factor (FIC), Fidelity Level (FL), and Species Therapeutic Index (STI). A total of 87 plant species belonging to 43 families were documented along with their medicinal uses. Euphorbiaceae is the most implicated family (9%) of the plants documented, and herbs (36%) were the prevalent life form while leaf (46%) was the most used plant part. Fevers are the most common diseases treated with the medicinal plants with 1012 use-reports, followed by skin diseases with 314 use-reports while the most common mode of preparation is decoction (37%). Telfaria occidentalis has the highest SPI and RFC (0.99, 0.99) while Khaya grandifoliola has the highest CII of 1.91. The community has EKI of 0.57 indicating a good knowledge of medicinal plants around them. Species such as Citrus aurantifolia, Khaya grandifoliola, and Ocimum gratissimum have high quantitative indices suggesting that they are effective in the treatment of various diseases in the community and therefore should be considered for pharmacological studies to validate their folkloric usages.

Comparative Assessment of Medicinal Plant Utilization among Balti and Shina Communities in the Periphery of Deosai National Park, Pakistan

Simple Summary

Traditional ecological knowledge is a key contributor to environmental sustainability; therefore, it is essential to identify and preserve this biocultural heritage. We documented traditional uses of plant species among the two marginalized communities, namely Baltis and Shinas, living in Deosai National Park, western Himalayas, Pakistan, using random and purposive sampling techniques targeting middle- and old-aged informants. In total, 47 medicinal plant species were recorded, which were cited by both Baltis and Shinas (42 and 38 plant species, respectively) to treat various diseases. Considerable homo- and heterogeneities were noted in vernacular names, plant part(s) used, drug formulation, and administration. Ribes alpestre, Aconitum violaceum, Delphinium brunonianum, Thymus linearis, and Swertia petiolata were the highly utilized species. In addition, medicinal uses of Allardia tomentosa, A. tridactylites, Jurinea dolomiaea, and Gallium boreale were reported for the first time from this region. Both Balti and Shina communities retain substantial biocultural and ethnological diversity, which has been reflected in the present survey.

Abstract

Traditional ecological knowledge, linguistic, and sociocultural perspectives are key contributors to environmental sustainability. Therefore, it is essential to identify and preserve this biocultural heritage, especially that of indigenous communities and minorities. We conducted an ethnobotanical survey to document the plant species used by the Balti and Shina communities living in the buffer zone of Deosai National Park (DNP), western Himalayas, Pakistan. A combination of random and purposive sampling techniques was adapted, targeting middle- and old-aged informants. A total of 46 semi-structured interviews were conducted and the gathered data were evaluated using relative frequency of citation (RFC) and through comparison with the ethnomedicinal literature. In total, 47 medicinal plant species belonging to 42 genera and 23 families were recorded. Baltis and Shinas cited 42 and 38 plant species, respectively, that were used to treat various diseases. About 60% of species were common among both communities, but 27.7% and 12.8% were exclusive to Baltis and Shinas, respectively. Considerable heterogeneity was noted in vernacular names, plant part(s) used, preparation, and administration. Ribes alpestre, Aconitum violaceum, Delphinium brunonianum, Thymus linearis, and Swertia petiolata were highly utilized species having RFCs > 50. In addition, 46% of medicinal uses, specifically that of Allardia tomentosa, A. tridactylites, Jurinea dolomiaea, and Gallium boreale, were reported for the first time from the region. Cross-cultural analysis revealed sociocultural gaps between both groups. Relatively, Baltis retained more ethnomedicinal knowledge and their traditional medicinal system is more closely associated with traditional Tibetan medicine. Generally, Balti and Shina communities retain substantial biocultural and ethnological diversity, which has been reflected in the present study. Our findings underline the importance and need for sustainable utilization of natural resources, specifically the plant species of this region. However, an in-depth ethnobotanical investigation may underpin the holistic comparative medical ethnobotany of the entire region.

The use of medicinal plants to prevent COVID-19 in Nepal

BACKGROUND

Medicinal plants are the fundamental unit of traditional medicine system in Nepal. Nepalese people are rich in traditional medicine especially in folk medicine (ethnomedicine), and this system is gaining much attention after 1995. The use of medicinal plants has increased during the COVID-19 pandemic as a private behavior (not under the control of government). A lot of misinterpretations of the use of medicinal plants to treat or prevent COVID-19 have been spreading throughout Nepal which need to be managed proactively. In this context, a research was needed to document medicinal plants used, their priority of use in society, their cultivation status, and the source of information people follow to use them. This study aimed to document the present status of medicinal plant use and make important suggestion to the concerned authorities.

METHODS

This study used a web-based survey to collect primary data related to medicinal plants used during COVID-19. A total of 774 respondents took part in the survey. The study calculated the relative frequencies of citation (RFC) for the recorded medicinal plants. The relationship between plants recorded and different covariates (age, gender education, occupation, living place, and treatment methods) was assessed using Kruskal-Wallis test and Wilcoxon test. The relationship between the information sources people follow and the respondent characteristics was assessed using chi-square test.

RESULTS

The study found that the use of medicinal plants has increased during COVID-19 and most of the respondents recommended medicinal plants to prevent COVID-19. This study recorded a total of 60 plants belonging to 36 families. The leaves of the plants were the most frequently used. The Zingiber officinale was the most cited species with the frequency of citation 0.398. Most of the people (45.61%) were getting medicinal plants from their home garden. The medicinal plants recorded were significantly associated with the education level, location of home, primary treatment mode, gender, and age class. The information source of plants was significantly associated with the education, gender, method of treatment, occupation, living with family, and location of home during the lockdown caused by COVID-19.

CONCLUSIONS

People were using more medicinal plants during COVID-19 claiming that they can prevent or cure COVID-19. This should be taken seriously by concerned authorities. The authorities should test the validity of these medicinal plants and control the flow of false information spread through research and awareness programs.

Ethno-medicinal uses of vertebrates in the Chitwan-Annapurna Landscape, central Nepal

Traditional knowledge on the use of animal products to maintain human health is important since time immemorial. Although a few studies reported food and medicinal values of different animals, a comprehensive ethno-medicinal study of vertebrates in Nepal is still lacking. Thus, present study is aimed at documenting the ethno-medicinal knowledge related to vertebrate fauna among different ethnic communities in the Chitwan-Annapurna Landscape, central Nepal. Data was collected by using semi-structured questionnaires and analyzed by using Use Value (UV), Informant Consensus Factor (ICF) and Fidelity level (FL). Results showed a total of 58 (53 wild and 5 domestic) species of vertebrate animals. They were used to treat 62 types human ailments. Four animals were also used for veterinary diseases and agriculture benefits. The most widely used species was Felis chaus (UV = 0.25) with 3 use-reports by 10 informants. Cardiovascular and dental problems had the highest ICF value (0.974) with cardiovascular problems having 351 use-reports for 10 animal species and dental problems having 77 use-reports for 3 animal species. The least ICF was found in ophthalmological problems (ICF = 0.833, use reports = 7 for 2 species). We concluded that the different animals were an important part of traditional medicine for the local people living in the Chitwan-Annapurna Landscape. However, the majority of animals and most likely to be threatened due to their uses. The present documented ethnozoological knowledge can be used in conservation and management of vertebrates so that they could be protected for future generations.

Ethnobotanical survey of the medicinal flora of Harighal, Azad Jammu & Kashmir, Pakistan

BACKGROUND

The present study is the first quantitative ethnobotanical evaluation of Harighal, an inaccessible and unexplored area of District Bagh Azad Jammu & Kashmir (AJK). The exploration, quantification, and comparison of ethnobotanical knowledge among different rural communities of the study area were mainly focused during field survey.

METHODOLOGY

In total, 79 informants (49 men and 34 women) were selected randomly to collect data using a semi-structured questionnaire. Various quantitative indices, including use value, relative frequency of citation, relative importance, fidelity level, and informant consent factor, were employed to evaluate the gathered information. Furthermore, primary data were also compared with twenty-two papers published from adjoining areas.

RESULT

A total of 150 medicinal plants belonging to 98 genera and 60 families were documented. Asteraceae, Fabaceae, and Rosaceae were the dominant families having 15 species each. Of these, 76 species were indigenous, 74 exotic, 136 were collected in the wild, 10 cultivated, and 4 both wild-collected and cultivated. Herbaceous taxa were the most used life form, and leaves were the most exploited plant part. Decoctions were the most preferred method used in preparation of herbal recipes. Three species viz. Mentha longifolia, Berberis lycium, and Galium aparine had the highest use value (1.05), relative frequency of citation (0.81), and relative importance value (96), respectively. The highest informant consensus factor (ICF) was reported for digestive disorders. Mentha longifolia, Punica granatum, Zanthoxylum alatum, and Olea ferruginea had 100% fidelity values. The Jaccard index revealed that uses of plants were more similar in two neighboring areas, i.e., Pearl Valley and Toli Peer.

CONCLUSION

Local inhabitants still prioritize herbal medicines as an effective way to treat a wide variety of ailments. Elders and health practitioners of the study area are well aware of indigenous knowledge about medicinal plants, but young people are not much interested in herbal practices. Thus, valuable knowledge about the use of plants is on the verge of decline.

Quantitative Ethnobotanical Study of Indigenous Knowledge on Medicinal Plants Used by the Tribal Communities of Gokand Valley, District Buner, Khyber Pakhtunkhwa, Pakistan

The current study on the traditional use of medicinal plants was carried out from February 2018 to March 2020, in Gokand Valley, District Buner, Pakistan. The goal was to collect, interpret, and evaluate data on the application of medicinal plants. Along with comprehensive notes on individual plants species, we calculated Use Value (UV), Relative Frequency of Citation (RFC), Use Report (UR), Fidelity Level (FL), Informant Consensus Factor (FCI), as well as Family Importance Value (FIV). During the current study, a total of 109 species belonging to 64 families were reported to be used in the treatment of various ailments. It included three families (four species) of Pteridophytes, 58 families (99 species) of angiosperm, one family (three species) of Gymnosperms, and two families (three species) of fungi. The article highlights the significance of domestic consumption of plant resources to treat human ailments. The UV varied from 0.2 (Acorus calamus L.) to 0.89 (Acacia modesta Wall.). The RFC ranged from 0.059 (Acorus calamus L. and Convolvulus arvensis L.) to 0.285 (Acacia modesta Wall.). The species with 100% FL were Acacia modesta Wall. and the fungus Morchella esculenta Fr., while the FCI was documented from 0 to 0.45 for gastro-intestinal disorders. The conservation ranks of the medicinal plant species revealed that 28 plant species were vulnerable, followed by rare (25 spp.), infrequent (17 spp.), dominant (16 spp.), and 10 species endangered. The traditional use of plants needs conservation strategies and further investigation for better utilization of natural resources.

An ethnobotanical study of medicinal plants used by the Tengger tribe in Ngadisari village, Indonesia

The people of Tengger, Indonesia have used plants as traditional medicine for a long time. However, this local knowledge has not been well documented until recently. Our study aims to understand the utilization of plants in traditional medicine by the people of Tengger, who inhabit the Ngadisari village, Sukapura District, Probolinggo Regency, Indonesia. We conducted semi-structured and structured interviews with a total of 52 informants that represented 10% of the total family units in the village. The parameters observed in this study include species use value (SUV), family use value (FUV), plant part use (PPU), and the relative frequency of citation that was calculated based on fidelity level (FL). We successfully identified 30 species belonging to 28 genera and 20 families that have been used as a traditional medicine to treat 20 diseases. We clustered all the diseases into seven distinct categories. Among the recorded plant families, Poaceae and Zingiberaceae were the most abundant. Plant species within those families were used to treat internal medical diseases, respiratory-nose, ear, oral/dental, and throat problems. The plant species with the highest SUV was Foeniculum vulgare Mill. (1.01), whereas the Aloaceae family (0.86) had the highest FUV. Acorus calamus L. (80%) had the highest FL percentage. The leaves were identified as the most used plant part and decoction was the dominant mode of a medicinal preparation. Out of the plants and their uses documented in our study, 26.7% of the medicinal plants and 71.8% of the uses were novel. In conclusion, the diversity of medicinal plant uses in the Ngadisari village could contribute to the development of new plant-based drugs and improve the collective revenue of the local society.

Ethnomedicinal knowledge of a marginal hill community of Central Himalaya: diversity, usage pattern, and conservation concerns

BACKGROUND

Indigenous communities use wild plants to cure human ailments since ancient times; such knowledge has significant potential for formulating new drugs and administering future health care. Considering this, the present study was undertaken to assess use value, diversity, and conservation concerns of medicinal plants used in traditional herbal care system of a marginal hill community in Bageshwar district of Uttarakhand in the Central Himalayan region of India.

METHODOLOGY

Extensive surveys were made in 73 villages to gather information on the ethnomedicinal use of plant species used in the traditional herbal healing system. A total of 100 respondents were identified (30 herbal healers called Vaidyas and 70 non-healers/natives) and interviewed using semi-structured questionnaires, target interviews, and group discussion. Some important indices such as the use-value index (UV), relative frequency citation (RFC), cultural importance index (CI), and informant consensus factor (F_ic) were calculated for the medicinal plants included in the present study.

RESULT

It was recorded that the community uses a total of 70 species with 64 genera and 35 families for curing various ailments. Family Lamiaceae recorded the maximum number of medicinal plants. Twenty-one species used most extensively in the traditional health care system. The major parts of the identified plants used for the treatment of various ailments were root/rhizome and leaf. The most common methods used for the preparation of these plants were decoction and infusion. Ocimum basilicum L., Cannabis sativa L., Citrus aurantifolia (Christm) Sw., Curcuma longa L., and Setaria italica L. had the highest rate of use report. RFC value ranged between 0.03 and 0.91 with highest values for Setaria italica, Zingiber officinale, Ocimum basilicum, and Raphanus sativus. The traditional knowledge is passed verbally to generations and needs to be preserved for the future bio-prospecting of plants that could be a potential cure to any future disease.

CONCLUSION

In recent years, the community has access to modern hospitals and medicinal facilities, although a considerable number still prefer medicinal plants for curing select ailments. It is suggested that these ethnomedicinal species need to be screened and evaluated further for their effectiveness for pharmacological activity. Also, significant efforts are required to conserve traditional knowledge and natural habitats of wild medicinal plants.
