Ethnobiological survey on medicinal plants used by gaddi and gujjar tribes of riparian region of Beas River of Himachal Pradesh in North Western Himalayas, India

Himachal Pradesh is one of the most species-rich regions in the world and a key center for the origin and diversity of numerous plant species. Ethnobotanical research is essential for exploring these diverse biological resources for medicinal uses. This study aimed to record the traditional knowledge of the tribal communities in Himachal Pradesh concerning the use of medicinal plants for treating diseases in humans and livestock. Despite this richness, there is a lack of detailed documentation about the use of therapeutic plants in this area. The indigenous communities in this region rely on traditional knowledge of medicinal plants, making it a valuable resource for further pharmacological and phytochemical research. The ethnobotanical surveys were conducted from August 2022 to July 2023, and our fieldwork took place in four districts (Kullu (1279 m), Mandi (760 m), Hamirpur (780 m) and Kangra (1200–1300 m) under various villages. The ethnobiological data was gathered through field surveys, open interviews, discussions, and semi-structured questionnaires conducted with 193 tribal participants aged 40 to 80 years. Informants were chosen using the randomized household interview and snowball sampling methods. The study documented 64 plants from 39 families, among which 58 species are angiosperms, 5 species are pteridophytes and one species is bryophyte utilized for therapeutic purposes. Rosaceae, Lamiaceae, and Ranunculaceae were the most used medicinal herb families. Rubus ellipticus (0.75) and Trillium govanianum (0.74) demonstrated the highest UV (Use value) values. The ICF (Informant Consensus factor) value revealed that nervous system disorders-related ailments were the most treated. This study explored the ethnobiological information of therapeutic flora from riparian vegetation within tribal communities while also assessing the present state of research and the practical application of their medicinal information. It underscores the potential for additional research to delve deeper into the indigenous properties of their therapeutic floras and emphasizes the importance of preserving their traditional medicinal wisdom.

Medicinal plant species used for contraception and reproductive health care in rural Uganda.

Medicinal plants form an integral part of traditional health care systems in Uganda and are known to possess a variety of bioactive compounds some of which are beneficial as contraceptives. This study documented indigenous traditional knowledge on medicinal plant species used in contraception and other reproductive health care-related issues in rural Uganda. An ethnobotanical study was conducted from December 2019 to August 2020 in four different regions of Uganda: Mpigi, Kamuli, Bushenyi and Arua. Data was obtained from 158 traditional medical practitioners using semi-structured questionnaires. Descriptive statistics were used to present the data while quantitative analysis of data was done using the informant consensus factor (FIC), Percentage Use Value (PUV) and Jaccard Index (JI). The study recorded 98 medicinal plant species with the potential to manage family planning and other reproductive health related conditions. The most represented family was Asteraceae with 18 species. Plant remedies were mainly prepared as decoctions (41%) and administered orally (36%). Most plant species (61%) were harvested from wild habitats. Herbs (50%) and leaves (50%) contributed the highest percentage of plant growth forms and parts used respectively. The FIC value of 0.6 demonstrated that the herbalists, traditional birth attendants and community elders tend to agree with each other regarding plant species used and administration. JI ranged from 13 % to 0.9 %, an indication of very low similarities between the plants used in family planning and traditional health care among the communities in the study areas. The most frequently cited plant species for family planning management were: Prunus africana (Hook.f.) Kalkman (14: with a PUV of 45.2 %): Sporobolus pyramidalis P.Beauv. (10: 19.6), Warburgia ugandensis Sprague (10: 23.1) and Dichrocephala integrifolia (L.f.) Kuntze (7 ': 26.9). There is a high diversity of the species and a wealth of indigenous traditional knowledge for contraceptives and reproductive health care. Species like Prunus africana, Warburgia ugandensis and Dichrocephala integrifolia with high percentage use values are trusted by the community and can be investigated further for contraceptive potential to confirm their efficacy.

Ethnomedicinal survey of the Paliyar tribe: a case study of Kadamalaikundu, Theni District

AbstractThe Paliyar tribe of Kadamalaikundu, Theni District of Tamil Nadu, India, has been deeply associated with forestry and ethnomedicinal practices for ages. The study aimed to identify the important medicinal plant species used by this tribe for ethnomedicinal purposes in the local vicinity. Eighty-nine informants were interviewed using the ‘specimen display’ and forest walk method, semi-structured open-ended questionnaires, interviews, and personal observations. The people from the region reported ninety-three plant species having medicinal properties. The Solanaceae family was recorded as the most dominant plant family, reporting seven different species of medicinal plants, followed by six species of the Acanthaceae family. In the study, Coccinia grandis had the highest use value (2.5), followed by Withania somnifera (2). In contrast, Cardiospermum halicacabum, Gossypium hirsutum, and Ocimum tenuiflorum with use value (1) and the ICF (Informant Consensus Factor) of value 1 accounted for 15 diseases out of forty-one categorized ailments. This study confirmed that the Paliyar tribe was dependent on a large number of medicinal plants for their primary healthcare and veterinary well-being, which require immediate conservation owing to their population fragmentation and the reluctance of the younger generation to adopt ethnomedicinal practices as occupation, which could lead to the loss of traditional knowledge as well. The study also documented the various important medicinal plant uses that could pave the way to the new pharmacological dimensions for modern wellness programs.

Ethnobotanical knowledge of plant species of the North-East of Morocco, with three provinces as a case study: Al Hoceima, Nador, and Jerada.

This study focuses on taxa found in the Northeastern part of Morocco and cited in the book “Al Jam’ li-Mufradat al-Adwiya wa’l-Aghdiya (The Book of Simple Drugs) by Ibn Al Baytar. The main objective of this study is to determine whether the taxa on our list are recognized by the populations in the three provinces of Northeastern Morocco, as well as to collect information about their traditional uses (medicinal or non-medicinal), their modes of preparation and administration, the plant parts used. All the data have been collected through conducting an open-ended, semi-structured interviews with randomly selected individuals. The informant consensus factor (FIC) was calculated to identify the level of agreement among informants regarding the use of medicinal plants for specific disease groups. During these ethnobotanical surveys, 1,177 persons were interviewed. We were able to record a total of 241 taxa belonging to 66 families with 1,264 uses mentioned in the three provinces. The results obtained confront us with the idea that there is a decline of autochthonous knowledge. They reveal that 32.12% of the local population considers itself ignorant of the uses of plants to cure illness, and that 66.78% prefer modern medicine despite possessing some knowledge of traditional medicinal plants. However, 790 medicinal uses recorded were classified according to the WHO’s international Classification of diseases (ICPC-2, International Classification of Primary Care), and 474 other uses were recorded, along with the transcription of new vernacular names for 107 taxa. This confirms the importance of ethnobotanical studies as it plays an important role in preserving the reservoir of indigenous knowledge from being lost over time.

Medicinal plants diversity among the oromo community in heban-arsi district of Ethiopia used to manage human and livestock ailments.

Medicinal plants are commonly employed mainly due their accessibility, affordability and potency. However, medicinal plants and the associated knowledge are disappearing at an alarming rate due to natural and anthropogenic causes and thus a need for their proper documentation conservation. This study was performed to document traditional knowledge related to use of medicinal plants in Heban-Arsi district, West-Arsi Zone, Oromia Regional State, Ethiopia. Interviews were conducted with 185 informants to identify medicinal plants used in traditional therapies in the study area. Informant consensus factor (ICF), rank order priority (ROP) values were computed, and preference ranking exercises were performed to assess the relative importance of medicinal plants. Descriptive and inferential statistics were used to measure and compare medicinal plants knowledge between social groups. A total of 120 medicinal plants were identified for being used to treat different human and animal illnesses in the study area. Most of the medicinal plants (76.4%) were uncultivated ones obtained from different habitats. Leaf was the most frequently used plant part constituting 62.6% of preparations. Oral was the most commonly used route of remedy administration (46%) in treating diseases. Gastrointestinal ailments category had the highest ICF value (0.83). In the study area, the highest rank order priority (ROP) values were recorded for Dombeya torrida (J.F. Gmel.), Artemisia absinthium L., Balanites aegyptiaca (L.) Del., Combretum pisoniiflorum Klotzsch) Engl., Celtis africana Burm. f, Ocimum gratissimum L. and Lagenaria sp. for their uses against snake poison, tuberculosis, liver disorder, stomachache, tuberculosis, febrile illness and liver disorder, respectively, each scoring a value of 100. Significant differences in medicinal plant use knowledge were recorded between male and female informants of different educational level, age and experience. Anthropogenic factors were the primary threats to medicinal plants in the area. The study area was found to be rich in medicinal plants that are useful in treating a wide range of human and animal illnesses. In future pharmacological and phytochemical investigations, priority needs to be given to medicinal plants of the highest ROP values and those that were reported against ailment categories scoring the highest ICF values.

Birds as sacred ‘children of god’, beholders of spirit and symbols of twinhood: Human–bird interaction among the Nuer in western Ethiopia

Abstract The deep connection between Indigenous communities and nature plays a pivotal role in biodiversity conservation. Ethiopia, one of Africa's priority countries for bird conservation, harbours 821 bird species and 83 ethnic groups of Indigenous people. However, cultural and spiritual ties between Indigenous peoples and bird species remain largely unexplored. This is particularly true for remote Indigenous communities such as the Nuer. Relying on preexisting bird survey data, we conducted focussed group discussions and semi‐structured interviews with Indigenous Nuer in western Ethiopia to explore human–bird interactions and documented associated traditional ecological knowledge and considered their conservation implications. We found that Nuers have strong ties with birds. In Nuer community, birds are collectively known by three interchangeable terms: ‘gaatkuoth’ to mean sacred children of god, ‘kuoth’ meaning bearers of spirit and ‘diit’ symbols of human twins (since birds nurture multiple offspring, they associate the incidence of twins in human with birds). We identified 71 culturally important bird species that were used in seven different use categories. Among these species, 10 were used as bushmeat, five for traditional medicine, eight as fish indicators, seven as omens (believed to indicate upcoming misfortunes), three as amulets (believed to protect against danger when bird's body parts are used as necklaces and bracelets), three as season indicators and 45 for their scenic beauty. An informant consensus factor for species in all use categories was &gt;90%, except for the scenic value, indicating a high homogeneity of knowledge about species uses. Bird species with multiple uses have significant cultural values among locals, emphasizing the need to understand these values in conservation efforts. Nuer traditional systems regulate the direct use of birds including for bushmeat. Hunting is permitted only by impoverished households during severe food shortages and is prohibited for those with a history of twins in their ancestry. The Nuer people exhibit a profound cultural connection to birds, viewing them as sacred and spiritually valuable beings. This deep‐seated reverence and traditional knowledge highlight the importance of integrating Indigenous perspectives into bird conservation strategies to enhance their effectiveness and respect cultural values.

Ethnopharmacological survey of the therapeutic use of camel urine in the Guelmim-Oued Noun and Laayoune-Sakia El Hamra regions of Morocco

The therapeutic use of camel urine (CU) has shown an increasing trend in recent decades for treating diverse ailments and infections. An ethnopharmacological survey was conducted to collect and document the ethnomedicinal knowledge of local people in the Saharan region of Morocco, including the Laayoune Sakia El Hamra and Guelmim Oued Noun regions, regarding the traditional use of CU for treatment. Semi-structured interviews with 384 traditional practitioners, camel herders, and rural and urban dwellers were conducted from December 2022 to June 2023. The collected data covered diseases treated, CU quality attributes, modes of preparation, dosage, administration, treatment duration, and mild side effects. Quantitative data analysis was performed through the relative frequency of citations, informant consensus factor, informant agreement ratio, cultural importance index, and fidelity level. The results showed that CU was collected from virgin female camels (46.7 %) and pregnant camels (51.6 %) at different age stages (39.7 %) in both wet and dry seasons (57.5 %). For the treatment of the most common ailments (cancer, liver diseases, gastric ulcers, diabetes, and tuberculosis), accounting for 69 %, the recommended regimen involved orally consuming one teacup (69 %) of fresh urine (70.6 %) on an empty stomach (91.1 %) once a day (87.1 %) four days a week (56 %). In the case of integumentary system problems, applying one (13.2 %) to three teaspoons (17.8 %) topically (10.3 %) was also effective. Secondary effects occurred in 48 cases (13.8 %), including diarrhea (13 cases), nausea (11 cases), headache (7 cases), constipation (7 cases), and dry mouth (8 cases). The duration of these effects ranged from 2 to 3 h. The present survey indicates that CU is still used in traditional medicine by local inhabitants of the southern regions of Morocco to cure various human illnesses. The outlined findings strongly suggest the usefulness of CU as a valuable source of bioactive molecules for pharmaceutical, dermo-cosmeceutical applications, and developing innovative food supplements that promote significant job creation and entrepreneurial prospects.

BackgroundHerbal medicine has been used for the treatment of human and livestock ailments since ancient times. Numerous rural and urban communities in Ethiopia practice traditional medicine and transfer the knowledge verbally from generation to generation. Thus, this study was conducted to document the traditional medicinal plants and associated indigenous knowledge in Dibatie district, Metekel zone, Benishangul Gumuz Regional State, western Ethiopia.MethodsThree hundred seventy-four (374) informants from 11 kebeles (the smallest administrative units) were selected and participated in the data delivery. The ethnobotanical data collection was carried out using semi-structured interviews, preference ranking, direct matrix ranking, field observation, market surveys, and focus group discussions, including voucher specimen collections. The ethnobotanical data were analyzed using descriptive statistics (frequency and percentage), ranking, comparison, and quantitative ethnobotanical techniques such as informant consensus factor, fidelity level index, Jaccard’s coefficient of similarity, and use value index.ResultsA total of 170 plant species were recorded to treat 79 human and 29 livestock ailments. Fabaceae (with 20 species) and Asteraceae (with 18 species) were the most dominant medicinal plant families in the area. Most remedial plants were herbs (61 species, 35.88%), followed by shrubs (39 species, 22.94%). The majority (135 species, 79.41%) of medicinal plants were harvested from wild sources and mainly possessed multiple remedy parts (41.17%) that are usually prescribed in fresh form (60.13%). The most commonly reported human ailment was snake venom, while blackleg was mostly reported among livestock diseases. The herbal medicines were mostly administered orally (52.20%), followed by dermal (17.62%) application. Embelia schimperi Vatke, Glinus lotoides L., Haplosciadium abyssinicum Hochst., Mucuna melanocarpa Hochst. ex A. Rich., and Phragmanthera macrosolen (Steud. ex A. Rich.) M.G.Gilbert had the highest fidelity level values (100%) against the corresponding ailments.ConclusionThe study area is rich in a diversity of potential medicinal plants and associated indigenous knowledge. Thus, appropriate conservation actions and careful utilization are essential to counteract the rise of anthropogenic threats and to ensure the continuity of plants with the related indigenous knowledge. Additionally, the medicinal plants should be validated through experimentation to integrate local knowledge with modern medications.

Documentation of spices and condiments as medicines by Reang community of Tripura
