Survey on the Traditional Use of Medicinal Herbs in Haiti: A Study on Knowledge, Practices, and Efficacy Prevention.

The use of medicinal herbs is highly developed in Haiti. However, there is a significant lack of knowledge in the literature on medicinal plants and their uses. The objective of this study was to determine the knowledge and practices of Haitian families for the prevention/treatment of COVID-19, influenza, and respiratory diseases, as well as the mode of preparation and administration of the plants. Individuals were interviewed using the TRAMIL questionnaire as the information holder. The data obtained were analyzed by calculating 5 indices (relative frequency of citation, use value, the family use value, informant consensus factor, and fidelity level). The study surveyed 120 Haitians and collected 75 plants from 43 botanical families. The botanical family most used for all these preventions and remedies is the Lamiaceae. The highest ranked species with a relative frequency of citation value > 0.3. Infusion, decoction, and in the form of punch are the methods used for the remedies. The study found that the use of herbal remedies is still prevalent in the study area, and many of the commonly used plants have been scientifically validated. However, some plants, such as Samyda rosea Sims, lack sufficient research and are recommended for further investigation.

Ethnozoological study of medicinal animals used by the inhabitants of the Kucha District, Gamo Zone, Southern Ethiopia

BackgroundAn ethnozoological study of medicinal animals in the Kucha district, Gamo zone, Southern Ethiopia, was conducted to investigate and document the use of traditional medicinal animals and the associated indigenous knowledge. Tribal people still make abundant use of animals and their parts to manage diseases in humans and even livestock.MethodA cross sectional study design and purposively sampling techniques were used. Data were collected from 132 respondents based on semi structured questionnaires. Focus group discussions (FGD) and Key informant interviews (KII) were conducted; Fidelity level (FL), Relative frequency of citation (RFC) and Informants’ consensus factor (ICF) were used to analyze species preference and importance.ResultsA total of 24 medicinal animals were identified with 13 species (54.2%) being mammals of which 5 species (20.8%) dominated. They were followed by arthropods, reptiles and fishes. Seven out of the total were domestic species (29%) and 17 (70%) were wild animals. The majority of these animals, i.e. 22 (91.7%), were used to treat human ailments; whereas 2 (8.3%) were used to treat livestock ailments. The ICF values varied from 0.8 to 1.The highest FL value (98%) was linked to the cow (cattle), the lowest (1.5%) to the scorpion. The RFC value (1.0) was highest for the cow and lowest (0.02) for the scorpion. Honey, milk, and butter were the most commonly used therapeutic animal products, but regarding direct uses, fresh/raw meat dominated. Out of ten ailment categories, headaches had the lowest ICF value (0.8). All others scored at least 0.9.ConclusionsIn rural areas, sick people often do not only have limited access to modern medical facilities, they actually prefer traditional treatments considering them to be more reliable and effective. It is therefore important to focus on documenting, conserving, and safeguarding the indigenous knowledge so that strategies to manage the traditional wisdom can be implemented in the future. To achieve these goals, it is important to make sure that medicinal animal species are available in sufficient numbers and neither threatened by habitat changes or overexploitation.

Ethnobotanical insights on the management of plant pests and diseases by smallholder farmers in Mpumalanga Province of South Africa

BackgroundPests and diseases are a major contributor to yield losses in sub-Saharan Africa, prompting smallholder farmers to seek cost-effective, accessible and ecologically friendly alternatives for crop protection. This study explored the management of pests and diseases affecting crops across eight selected villages in Ehlanzeni District, Mpumalanga Province, South Africa.MethodsA total of 120 smallholder farmers were purposefully selected utilising the snowball technique. Information on the management of plant pests and diseases was collected through interviews and focus group discussions using semi-structured interview schedules. Ethnobotanical indices, including relative frequency of citation (RFC), use-value (UV) and informant consensus factor (Fic), were used to quantify and rank the plants used for crop protection in the study area.ResultsTwenty-three plant species (16 naturalised exotics and seven indigenous plants) belonging to 16 families were used for managing pests (vertebrates and invertebrates) and diseases (fungal and bacterial related) affecting crops in the study area. The dominant (100%) crops cultivated by the participants were Allium cepa L., Mangifera indica L., Solanum lycopersicum L. and Zea mays L. The RFC value ranged from 0.08 to 0.83 and the three most popular plants for crop protection were Capsium annuum L. (0.83), A. cepa (0.63) and Dichrostachys cinerea (L.) Wight & Arn. (0.43). In terms of the UV, the five most promising plants used as biocontrol were Tulbaghia violacea (0.13), A. cepa (0.12), C. annuum L. (0.09), Solanum campylacanthum Hochst. Ex A.Rich.(0.09) and Pinus pinaster (0.08). Based on the Fic, four categories were established and dominated by fungal diseases (0.64). Furthermore, T. violacea and A. cepa were the most often mentioned plants used against fungal conditions. Other categories cited were bacterial diseases (0.3), invertebrate pests (0.11) and vertebrate pests (0.14), an indication that smallholder farmers had limited agreement or common knowledge about the plants used for their management. The preparation methods included maceration (38%), decoction (38%) and burning (24%). Foliar application (67%) and soil drenching (33%) were used for administering plant extracts during the management of crop pests and diseases.ConclusionThe study highlights the importance of botanicals and associated indigenous knowledge among smallholder farmers in Mpumalanga Province, South Africa. It is pertinent to explore the valorisation of these botanicals by generating empirical data on their biological efficacies and phytochemical profiles.

The main aim of the present study was to gather comprehensive data on the wild edibles found in Dakshin Dinajpur, West Bengal, India, assess their cultural value, and comprehend how they contribute to the local tribes' attainment of food security. We gathered traditional knowledge about edible wild plants by administering a semi-structured questionnaire. Data collection followed standard protocols. To determine which species were most frequently cited and of cultural significance, the gathered data were subjected to specialized statistical analysis using tools such as the Cultural Food Significance Index (CFSI) and Relative Frequency of Citation (RFC). To determine how similar food plants are used in various Balurghat District localities and neighboring areas, the Jaccard Similarity Index (JI) was employed. A total of 1,603 citations were made by the 96 participants for 63 types of wild edibles spread across 36 families. Among the 63 species, 60 species were angiosperms, three species were pteridophytes. The RFC value was found to be in the range of 0.05-0.07. The most constantly referred species was identified as Madhuca longifolia (L.) J. F. Macbr. (RFC= 0,76; FC= 116). A total of 13 wild edible species was identified as the most traditionally valuable species in the locality including Marsilea vestita Hook. & Grev., Colocasia esculenta (L.) Schott, Termitomyces heimii Natarajan, Enydra fluctuans Lour etc. For the tribal community of eastern India, using these wild edibles scientifically and sustainably can be a smart move towards achieving multiple health benefits and food security. Furthermore, culturally acceptable species can be a good source for nutraceutical bioprospecting.

Medicinal plants used in Gabon for prophylaxis and treatment against COVID-19-related symptoms: an ethnobotanical survey.

Background: Gabon faced COVID-19 with more than 49,000 individuals tested positive and 307 recorded fatalities since the first reported case in 2020. A popular hypothesis is that the low rate of cases and deaths in the country was attributed to the use of medicinal plants in prevention and treatment. This study aimed to document the plants used for remedial and preventive therapies by the Gabonese population during the COVID-19 pandemic and to pinpoint specific potential plant species that merit further investigation. Methods: An ethnobotanical survey involving 97 participants was conducted in Libreville. Traditional healers and medicinal plant vendors were interviewed orally using a semi-structured questionnaire sheet, while the general population responded to an online questionnaire format. Various quantitative indexes were calculated from the collected data and included the relative frequency of citation (RFC), use value (UV), informant consensus factor (ICF), relative importance (RI), and popular therapeutic use value (POPUT). One-way ANOVA and independent samples t-test were used for statistical analyses. p-values ≤0.05 were considered significant. Results: The survey identified 63 plant species belonging to 35 families. Prevalent symptoms treated included fever (18%), cough (16%), fatigue (13%), and cold (12%). The demographic data highlighted that 52.58% of male subjects (p > 0.94) aged 31-44 years were enrolled in the survey, of which 48.45% (p < 0.0001) and 74.73% (p < 0.99) of informants had university-level education. In addition, the results indicated that a total of 66% of the informants used medicinal plants for prophylaxis (34%), for both prevention and treatment (26%), exclusively for treatment (3%), and only for prevention (3%) while suffering from COVID-19, against 34% of the participants who did not use plants for prevention or treatment. Annickia chlorantha, Citrus sp., Alstonia congensis, Zingiber officinale, and Carica papaya emerged as the most commonly cited plants with the highest RFC (0.15-0.26), UV (0.47-0.75), and RI (35.72-45.46) values. Most of these plants were used either individually or in combination with others. Conclusion: The survey reinforces the use of traditional medicine as a method to alleviate COVID-19 symptoms, thereby advocating for the utilization of medicinal plants in managing coronavirus infections.

Folk medicinal plants in forest fringe villages of tribal’s hill districts of Nagaland, India

In forest fringe villages, folk medicines play a pivotal role in human health care management. The aim of present study was to document the plants employed in the folk medicines by ethnic groups inhabiting forest fringe villages of Nagaland. Field survey was conducted for over two years in 32 forest fringe villages of Nagaland. The data were collected through semi-structured interviews and quantitatively analyzed by statistical tools i.e., Use-value, Relative frequency of citation and Informant consensus factor to identify promising plants for future studies. This research documented 96 medicinal plants employed in the treatment of 59 ailments of human being.

Juss., Phyllanthus emblica L. with 0.67 as UV and 3.6 as Rfc. Maximum consensus among informants was observed for the treatment of tooth and gum ailment and under this category Solanum aculeatissimum Moench was frequently cited by informants. Those plants which receive high relative frequency of citation values may serve as potential source for pharmacological studies, especially Azadirachta indica A. Juss. (used as insect repellent), Phyllanthus emblica L. (used in abdominal pain and indigestion), Alstonia scholaris (L.) R.Br. (in flatulence), Aloe vera Mill. (in constipation), Canna indica L. (in genital infection), Gmelina arborea Roxb. ex Sm. (prevent miscarriage), Parkia timoriana (DC.) Merr. (in bleeding piles), Carica papaya (DC.) Merr. (cure ringworm), Solanum aculeatissimum Moench (in foot and toe infection), Thalictrum foliolosum DC. (for vomiting and indigestion), Mentha spicata L. (in stomach ache), Elettaria cardamomum (L.) Maton (incough and cold), Zingiber officinale Roscoe (in cough and cold) and Persicaria hydropiper (L.) Delarbre (in skin infection).

Ethnobotanical study on edible flowers in Xishuangbanna, China

BackgroundEdible flowers (EFs) represent valuable sources of both food and medicinal resources, holding the promise to enhance human well-being. Unfortunately, their significance is often overlooked. Ethnobotanical studies on the EFs are lacking in comparison with their botanical and phytochemical research. The practice of consuming flowers as food has a rich culture and long history in China, especially among different linguistic groups in Xishuangbanna, Yunnan. However, economic activities have led to a decline of this tradition. Consequently, preserving the traditional knowledge and culture tied to the EFs in Xishuangbanna becomes both essential and pressing.MethodsThe field ethnobotanical survey was conducted in Xishuangbanna during five visits in April 2021 and May 2023, covering 48 villages and 19 local markets of all three county-level areas and 9 different linguistic groups. By conducting a comprehensive literature review and on-site field surveys, relevant information regarding the EFs of Xishuangbanna was systematically collected and documented. Additionally, the relative frequency of citation (RFC) values were calculated from the survey data.ResultsA total of 212 taxa (including species and varieties) of EFs from 58 families and 141 genera were documented in the study area. The edible parts of flowers were classified into 13 categories including peduncle, petal, flower buds, inflorescence as a whole, and etc. They were consumed in 21 ways and as 8 types of food. The inflorescence was the most commonly consumed category, accounting for 85 species (40.1%) of the total categories. They always eat flowers as vegetables (184 species, 86.8%). The preparing form of stir-frying was the preferred food preparation method (138, 65.1%). The Xishuangbanna locals had profound knowledge of which EFs required specific processing to remove their toxicity or bitterness. The dishes can be made from either exclusively from the flowers themselves or by incorporating them alongside other plant parts like stems and leaves. Some EFs with high RFC value, such as Musa acuminata and Bauhinia variegata var. candida, showed significant cultural meanings. These edible flowers occupy specific positions in local traditional culture.ConclusionTraditional knowledge regarding edible flowers holds substantial significance and serves as a representative element of the flower-eating culture in Xishuangbanna. Nevertheless, this knowledge and cultural practice are currently decreasing. Serving as a bridge between tradition and modernity, the flower-eating culture, which derives from local people’s practical experience, shows the potential of EFs and can be applied to the conservation of biocultural diversity, healthy food systems, and sustainable development.

The importance of wild edible plant and macrofungi diversity to attain food security for the tribes of eastern India—a quantitative study

BackgroundInventorization and promotion of traditionally used local flora can be a better option to gain a wide range of alternative edible resources and multiple nutritional benefits. A perusal of literature highlighted the poor nutritional status of the tribal community living in eastern India and pointed out the potential lack of information regarding locally available wild edible resources.ObjectivePresent study aimed to document detailed information on wild edibles of eastern India, evaluate their cultural significance, and understand their role in achieving food security for the local tribes.Materials and methodologyTraditional knowledge of wild edibles was collected using a semi-structured questionnaire. Standard protocols were followed for collecting data. The collected data were analyzed using specific statistical tools like Relative frequency of citation (RFC), and Cultural food significance index (CFSI) to identify the most cited and culturally significant species. Jaccard similarity index (JI) was used to check the similarity of food plant use in different localities and adjoining areas of the laterite region in eastern India.ResultsA total of 2,603 citations were made by the 153 participants for 83 types of wild edibles spread across 48 families. Among the 83 species, 65 species were angiosperms, three species were pteridophytes and the rest 15 were from fungal groups. The RFC value ranged from 0.04 to 0.76, and Madhuca longifolia (L.) J.F.Macbr. was identified as the most frequently cited species (FC = 116; RFC = 0.76). The Cultural food significance index (CFSI) value varied from 0.2 to 844, and thirteen wild edibles like Colocasia esculenta (L.) Schott, Enydra fluctuans Lour., Marsilea vestita Hook. &amp;amp; Grev., Termitomyces heimii Natarajan, etc. were identified as culturally most important in the locality.ConclusionPresent study concludes that the local flora and macrofungi diversity is a treasure trove for fulfilling human hunger and gaining enough nutritional benefit. Scientific and sustainable utilization of these wild edibles can be a wise step to attain multiple health benefits and food security for the tribal community of eastern India. Moreover, culturally accepted species can be opted as a good source for bioprospecting nutraceuticals.

Ethnoveterinary survey of trypanocidal medicinal plants of the beninese pharmacopoeia in the management of bovine trypanosomosis in North Benin (West Africa)

Cattle breeding is of great socio-economic importance for Benin's cattle farmers in general and those of North Benin in particular. The objective of this study is to inventory the natural products of medicinal plants of the Beninese pharmacopoeia for the management of trypanosomes in cattle in North Benin. The methodology consisted of individual and semi-structured interviews with cattle farmers on the use of medicinal plants. A total of 360 cattle farmers were selected and interviewed in twelve villages in four municipalities (Tchaourou, N'dali, Bembèrèkè and Gogounou) in northern Benin. Different quantitative ethnobotanical indices were calculated to determine the level of use of plant species. The Relative Frequency of Citation (RFC), the Informant Consensus Factor (ICF = 0.918) and the Generic Coefficient (Rg = 1.04) were evaluated. The knowledge of medicinal plants was influenced by the level of education and the main activity of those who practiced animal husbandry. The results yielded 48 medicinal plants for veterinary use belonging to 46 genera and 28 families. The Leguminosae family (12.50%) was the most represented. The most cited plants with a RFC above 10% were K. senegalensis, P. africana, K. africana, M. inermis, S. latifolius, M. polyandra. The parts used were leaves (46.15%); barks (24.62%) and roots (15.38%). Decoction (53.23%), plundering (32.26%) and maceration (11.26%) were the main methods of preparation. The administration was mainly by oral route. The calculated indices show a high diversity of medicinal plants with trypanocidal properties in the control of cattle trypanosomosis in the Sudanese and Sudano-Guinean zones of northern Benin. Plant species with high citation and RFC values should be selected for comprehensive pharmacological and phytochemical research to validate this ethnomedical knowledge in the management of cattle trypanosomosis.

Wild leafy vegetables: A potential source for a traditional Mediterranean food from Lebanon

IntroductionIn Lebanon, wild leafy vegetables (WLVs) continue to be an essential component of people's diet. Nevertheless, little ethnobotanical research has addressed this important potential source for food and nutrition.MethodsIn this study, an ethnobotanical survey was carried out between 2018 and 2022 across 21 villages/towns involving 151 local informants by semi-structured interviews.Results and discussionA list of 158 plant species which was still gathered and consumed by traditional Lebanese communities was compiled. The species belonged to 21 families and the most diverse families were Asteraceae (77 species), Brassicaceae (22), and Apiaceae (11). Native species accounted for 147 of the cited species, five of which were endemics to Lebanon and Syria. According to the Relative Frequency of Citation (RFC) index, Anchusa azurea, Centaurea hyalolepis, Chondrilla juncea, Eruca vesicaria, Pseudopodospermum molle, Pseudopodospermum papposum, and Taraxacum sect. Taraxacum were reported for the first time among the top popular species. Basal rosettes were the main parts consumed both raw and/or cooked. Informants perceived a decline in availability primarily due to habitat loss and land degradation. According to the International Union for Conservation of Nature (IUCN), six of cited species were classified as globally threatened (EN or VU), five of which were narrow endemics. These species scored substantial RFC values. Findings indicate that WEVs of Lebanon offer a promising potential to support food diversity and dietary quality of traditional communities and that threatened endemic species present a high conservation priority. Future research on nutritional contents of these species and highly rated WLVs is recommended.

The most commonly used plant parts were leaves (33.1%) followed by fruits (16.1%), while the main method of remedy preparation was decoctions (33.3%). The highest RFC value was recorded for Geranium wallichianum (0.47), followed by Berberis lycium (0.44). Lamiaceae was the most cited family (FIV, 231), followed by Polygonaceae (73). Five plant species were found to be endangered, 39 species were vulnerable, 32 species were rare, and 12 species were found to be infrequent. The medicinal flora of the area is under severe biotic pressure and needs proper conservation; otherwise, they will be lost in the near future.

Ethnopharmacological Survey of Medicinal Plants Used by Traditional Health Practitioners and Indigenous People in Chittagong Hill Tracts, Bangladesh for the Treatment of Dysentery

Dysentery is frequently associated with high morbidity and mortality and is found in young children and mainly affects those in developing nations. Rural people across the world trust on herbal remedies and homeopathic medicines for their primary health care on account of their easy accessibility, efficacy and exceptionally cost ampleness in relation to modern drugs. The purpose of the present study was to compile knowledge of traditional healers and indigenous people in Chittagong hill tracts, Bangladesh, including Rangamati, Bandarban and Khagrachari for the treatment of dysentery. The ethnomedicinal data was gathered from January 2019 to January 2020 through open and focused group discussions and individual meetings utilizing semi-structured questionnaire. An aggregate of 75 people were interviewed, including traditional health practitioners. Frequency and percentage were utilized to sum up the data. Relative frequency of citation (RFC) was determined and inclination positioning activities were led to appraise the significance of the revealed medicinal plants. An aggregate of 90 medicinal plants from 52 families and 79 genera were recorded during the survey. Leaves were discovered to be the most largely used plant part (35%) followed by root (19%) and herbs (40%) were the essential wellspring of medicinal plants, followed by trees (20%). The major mode of preparation is juice (68%) followed by paste (11%) and cooked form (7%). Centella asiatica scored the highest RFC value (0.773). The survey addresses the preliminary information of certain medicinal plants having anti-dysenteric property. However, further phytochemical investigation, validation and clinical trial sought to be conducted, with need given to those that scored the most elevated RFC values prior to utilizing these plants as an option in contrast to modern medicine.

Small regions as key sources of traditional knowledge: a quantitative ethnobotanical survey in the central Balkans

BackgroundStarting from the idea that unexplored areas may yield new and different ethnobotanical information, we performed a survey of traditional uses of plants in two neighboring districts situated in east Serbia (Bor and Aleksinac), both lacking in previous ethnobotanical reports, but characterized by an interesting history and culture, together with some specific features. In this study, we hypothesized that such small and specific areas could be of high ethnobotanical importance.MethodsSemi-structured interviews were used with 155 informants. Relative cultural importance (RCI) indices, such as the frequency of citation (FC), relative frequency of citation (RFC), relative importance index (RI), informant consensus factor (ICF-FIC), use value (UV), fidelity level (FL) and Jaccard index (JI), were calculated, and principal coordinate analysis (PCoA) was performed.ResultsIn this study, 2333 use-reports and 114 plants were recorded. Of the 101 medical herbs, 33 are included in the European Pharmacopoeia Edition 8.0. The most frequently used mode of preparation was as an infusion (50.0%), while leaf (44.7%) was the most used plant part. The highest FC and RFC values were recorded for Hypericum perforatum L. (13.1 and 0.2, respectively), while the highest RI was documented for Urtica dioica L. (1.0). ICF and FL indices showed important differences among selected groups of informants. The PCoA showed three homogeneous plant groups. Plants were mostly used for the treatment of digestive (49.1%), circulatory (41.2%) and respiratory system disorders (35.1%). Thirty-seven (32.5%) herbs were used for human nutrition, 14 (12.3%) in veterinary medicine, 17 (14.9%) in rituals and ethnoculture, while 24 (21.0%) for miscellaneous purposes. The highest degree of similarity was determined with studies conducted in close proximity. Four species are new to Balkan ethnobotany. New uses for some well-known plants are highlighted.ConclusionThe study indicated that small and specific areas in the Balkans may be an important reservoir of ethnobotanical knowledge.

Background: Medicinal plants are the only possible solution to facilitate and treat different complications of human beings. The local residents of District Malakand are dependent on medicinal plants for their primary healthcare. The aim of this study was to document medicinal plants and associated traditional knowledge of District Malakand, Khyber Pakhtunkhwa. Methods: The area was frequently visited from March to August in 2018-2019, during the peak flowering season for the collection of specimens and semi-structured interviews on the uses of medicinal plants. A total of 150 participants selected randomly and the demographic information (age, gender) and status of conservation was aggregated using a semi-structured questionnaire collected from each site. Informants were interviewed in their local language (Pashto). Results: A total of 62 ethno-medicinal plant species belonging to 37 families were recorded. A considerable proportion of the ethno-medicinal plant species were used for gastro-intestinal disorders. Relative Frequency of Citation (RFC) ranged from 0.48 to 0.3. The highest RFC value was registered for Jasminum officinale 0.48. Similarly, the UV (Use Value) range from 0.92 to 0.35, with highest values for Citrus medica (0.92), Lagenaria siceraria (0.55), and Lycopersicum esculentum (0.5). Older participants from 55-70 years of age showed higher knowledge about plants, followed by the age group 45–55. Conclusion: In the present study, some plants were of key importance i.e., Citrus medica, Lagenaria siceraria, Lycopersicum esculentum, Lactuca sativa and Brassica rapa. This documentation of medicinal plants and their uses shows the rich tradition in ethno-medicinal knowledge of the District Malakand, Pakistan.

Perception and knowledge of community people on invasive Alien Plant species in Chandak-Aunla Ghat and Hat-Kalika watersheds of Kailash sacred landscape - India: A case study

Invasive alien plant species (IAPS) are considered the second most important agent after habitat destruction for species endangerment and extinction. Though dozens of alien invasive plant species (IAPS) occur in the Indian Himalayan region, information on distribution and perceived impact is lacking in the western Himalaya. In the present study, 701 randomly selected households in 45 villages were surveyed through questionnaire surveys in Chandak-Aunla Ghat (329) and Hat-Kalika (372) watersheds in Kailash Sacred Landscape (KSL-India) to know their view on the issues associated with the IAPS and attitudes towards their management. The knowledge, perception, use and management strategies of different IAPS were analyzed. Only 39% of females and 27% of males had knowledge of IAPS. The highlights of the study are: i) Ageratina adenophora had the highest Relative Frequency of Citation value among 14 major IAPS in the study area, ii) informants of Hat-Kalika showed a low richness of knowledge and sharing with their family members as compared to Chandak-Aunla Ghat, iii) respondents perceived IAPS negatively and rated biological invasion and habitat loss as major environmental problem, iv) the major management strategies identified were restoration, eradication, community education and information, and v) perception and level of knowledge sharing on invasive species among age classes and gender have implications for stakeholders and policymakers in management of IAPS.

Ethnopharmacological evaluation of medicinal plants used to treat diabetes mellitus in Maidan valley, Dir Lower, Pakistan

This ethnopharmacological investigation aims to collect, identify, and document distinguishable medicinal plant species and remedies used by the local people for the management of diabetes in the Maidan valley in the district Dir Lower, Khyber Pakhtunkhwa, Pakistan. The local people of the valley have relied on botanical antidiabetic herbal formulations. The ethnobotanical interviews, questionnaires, inquiries, and group discussions were conducted from March 2019–January 2022 to obtain traditional knowledge from the local people. Quantitatively, ethnopharmacological data were analysed using indices, Relative Frequency of Citation (RFC) and Use Value (UV). The study identified 42 plant species belonging to 36 genera and 27 botanical families. Most of the species belong to Poaceae, while leaves were the most frequent morphological parts used. In this study, powder was the primary mode of herbal formulation. The highest RFC value was 0.47 obtained for Ziziphus nummularia (Burm.f.) Wight and Arn, and the highest UV was 0.97 for Sarcococca saligna Mull Arg. Local communities of the area use a large number of plant species for diabetes shows the importance of herbal formulation in the basic human ailments of this remote area. In future studies, we hope these medicinal plants will be further phytochemically screened for new antidiabetic properties.
