Ethno-medicinal application of plants in the eastern region of Shimoga district, Karnataka, India

Aim of the study

The present paper aimed to document and study the role of traditional herbal drugs in the treatment of human and veterinary ailments by communities residing in the eastern part of Shimoga district of Karnataka in India and to determine the consensus of informant's knowledge on different category of ailments and fidelity level of plant species in treating particular disease.

Methodology

The ethno-medico-botanical information was collected from herbal healers and knowledgeable elder people residing in 15 randomly selected villages using semi-structured interviews. The data were subjected to informant consensus factor (ICF) and fidelity level (FL) analyses.

Results

Eighty-five plant species of 41 families used to treat 31 human and 10 veterinary ailments were documented. Those medicinal plants which are effective in the treatment of liver complaints category had high ICF (0.77) and the skin diseases and disorders category attracted low ICF (0.12). Certain medicinal plants like Cyclea peltata, Justicia adhatoda, Memecylon umbellatum, Phyllanthus amarus and Tabernaemontana alternifolia were assigned with high degree of FL (100%) value and certain species like Cassia fistula was assigned with very low FL (25%). Some of the noteworthy medicinal uses of plant species in the study area were not reported for such purposes in the previously published literature on ethnobotany.

Conclusion

The local communities residing in eastern part of Shimoga district depended on herbal formulations for the treatment of diseases and disorders that affected them and their animals, as well. A high ICF and FL values indicated the possible occurrence of valuable bioactive compounds in certain plants and such of these plants need scientific evaluation for their pharmacological activities.

Medicinal plant use in two Andean communities located at different altitudes in the Bolívar Province,Peru

Ethnopharmacological relevance

The study documents current medicinal plant knowledge and use in two Andean communities and depicts the dynamic nature of ethnobotanical relationships by illustrating cultural integration of biomedicine and local plant medicine into a complementary system.

Aim of the study

In order to elucidate the importance of medicinal plants, the following research questions were addressed: Which position do medicinal plants have in the local health care system? Which plants are used medicinally, and do they differ between the communities? Is their use supported pharmacologically?

Materials and methods

Fieldwork was done for seven months in 2010. Semi-structured interviews were conducted with 120 informants in Uchumarca and Pusac/San Vicente de Paúl, and the medicinal plant species mentioned by the informants were vouchered.

Results

In total, 2776 plant remedy use reports were recorded. Most people in both communities know at least some medicinal plants, usually from their parents, grandparents, sometimes from books. There are different types of local plant specialists, who are consulted above all for the treatment of diseases thought to have a magical origin or for recommendations of plants to treat minor diseases. Overall, 140 medicinal plants were documented, with a conformity of over 90% between the communities. The effective use of the most frequently cited medicinal plants is supported by scientific literature. Most uses were reported for the treatment of gastrointestinal (17%), nervous (14%), respiratory (14%), urological (13%) and dermatological diseases (8%); nervous diseases were more prevalent in the mountain community, while dermatological and urological diseases were more common in the valley.

Conclusions

People combine medicinal plant use and biomedicine depending on the kind of disease, their beliefs, and their economic situation. The local use of different available medical resources is reflected by the combination of related epistemologies to explain disease causes. Medicinal plant use and biomedicine complement each other to form the local health care system.

Consensus of local knowledge on medicinal plants among traditional healers in Mayiladumparai block of Theni District, Tamil Nadu, India

Aim of the study

The role of ethnobotany in drug discovery is huge but there are criticisms over such studies due to their qualitative nature. The present study is aimed at quantitatively abstracting the medicinal plant knowledge of the healers trained in traditional ways, in Mayiladumparai block of Theni District, Tamil Nadu, India.

Materials and methods

The interviews and field observations were carried out in all the 18 village panchayaths from January to June 2010, consisting of 148 field days. The interviews were conducted with 80 traditional healers, after obtaining prior informed consent. Successive free listing was used to interview the informants. The informant consensus factor (F_ic) was calculated to estimate the use variability of medicinal plants. Fidelity index and Cultural importance index were also calculated to analyze the data.

Results

This study recorded the ethno-medicinal usage of 142 ethno-species belonging to 62 families that were used to prepare 504 formulations. Jaundice had the highest F_ic value than all the illness categories studied. Phyllanthus spp. was the highly cited medicinal plant to treat jaundice and had high fidelity index value. This was followed by Senna angustifolia and Terminalia chebula as laxatives. The highly cited medicinal plants in each group with high F_ic value were Pongamia pinnata (antiseptic), Aerva lanata (antidote and snakebite), Blepharis maderaspatensis (cuts and wounds), Abutilon indicum (hemorrhoids), Ruta graveolens (spiritual medicine), Ocimum tenuiflorum (cough), and Solanum trilobatum (pulmonary ailments). Phyllanthus spp., was the most culturally significant species according to this index, followed by Borassus flebellifer.

Conclusion

The process of drug discovery has become highly expensive and post-approval and post-marketing withdrawal of drugs is continuing. In such scenario, reverse pharmacology is considered an attractive option. The medicinal plants enumerated in this study with high number of citations and high F_ic values for illness categories might give some useful leads for further biomedical research.

Screening of anti-diarrhoeal profile of some plant extracts of a specific region of West Bengal,India

Ethanol extract of four different plants of the Khatra region of the Bankura district of West Bengal, India were evaluated for anti-diarrhoeal activity against different experimental models of diarrhoea in rats. The extracts of Ficus bengalensis Linn. (hanging roots), Eugenia jambolana Lam. (bark), Ficus racemosa Linn. (bark) and Leucas lavandulaefolia Rees (aerial parts) showed significant inhibitory activity against castor oil induced diarrhoea and PGE₂ induced enteropooling in rats. These extracts also showed a significant reduction in gastrointestinal motility in charcoal meal tests in rats. The results obtained establish the efficacy of all these plant materials as anti-diarrhoeal agents.     

Ethnomedicinal practices in different communities of Uttara Kannada district of Karnataka for treatment of wounds

Ethnopharmacological relevance

Uttara Kannada district is located in the heart of the Western Ghats, one of the biodiversity hotspots, in Karnataka state of India. The thick evergreen forests are home to several ethnic communities. The study was under taken for documentation and analysis of ethnomedicinal plants in the treatment of wounds.

Materials and methods

Field trips were made in Uttara Kannada district to identify the key informants. The collection of information was through semi-structured open ended interviews with a questionnaire. The questionnaire was designed to obtain the information about their experience in the field of treatment, number of patients treated per week, knowledge about the medicinal plants, vernacular names, parts of the plants used and other ingredients added during the drug formulations. Plants mentioned for treatment were photographed in the field, cuttings of the samples were taken and voucher specimens are deposited in the herbarium of P.G. Department of Botany, Karnatak University, Dharwad. The information such as botanical name, status, family, vernacular name habit and habitat, statistical analysis like percentage of parts used, Use value (UV) and Informants Consensus Factor (ICF) are provided.

Results

Present study resulted in recording 106 medicinal plant species of 55 families and 86 formulations to treat different types of wounds by 44 key informants. Among the 106 plants recorded four species are endemic to India and 22 species have the nativity outside India. Rest of the species have nativity both in India and elsewhere. The highest number of species belonged to Apocynaceae and Rubiaceae (6 species each). Trees are used more often (35.84%), followed by herbs (28.30%), shrubs (23.58%), climbers (11.32) and parasites (0.80%). Leaves are the major part of the plants used in the formulations (28.57%). The highest Use value is for Calycopteris floribunda (1.80), followed by Rauvolfia serpentina and Achyranthes aspera (1.67). The different types of wounds treated by traditional healers are classified into 15 categories and the highest ICF scored is for the burns (0.66).

Conclusions

Ethnomedicinal survey in Uttara Kannada district of Karnataka revealed uses of 106 plants in traditional practices for curing various types of wounds. The statistical analysis confirmed high degree of sharing the knowledge amongst 44 key informants. Information about the largest number of remedies was obtained from the Havyaka Brahmin ethnic community which has strong Sanskrit background.     

Mao's heritage: Medicinal plant knowledge among the Bai in Shaxi,China, at a crossroads between distinct local and common widespread practice

Ethnopharmacological relevance

The study focuses on medicinal plant knowledge among the Bai in the Shaxi Valley, Northwest Yunnan, where no ethnobotanical study has been conducted so far. In an area of high biodiversity, distinct medicinal plant knowledge is documented and the influence of herbals on local knowledge is revealed.

Aim of the study

To analyse current medicinal plant knowledge among the Bai in the context of the influence of the Han culture and mainstream Chinese herbal medicine.

Materials and methods

During fieldwork in summer 2005, semistructured interviews were conducted with 68 stakeholders, and voucher specimens of all plants mentioned were prepared.

Results

A total of 176 medicinal plant species were documented and 1133 use-reports have been collected. Overall, 91.5% of the documented plants are already established as known drugs, and are mentioned in books on medicinal plants in Yunnan and China. Furthermore, the way in which they are used largely coincides. Fourteen plant species represent novel recordings, 9 of which were independently mentioned by three or more informants.

Conclusions

The medicinal plant knowledge of the Bai is strongly influenced by mainstream Chinese herbal medicine and especially by medicinal plant books from the 1970s, which were distributed under Mao Zedong's directive to improve rural health care. We conclude that these herbals have exerted, and continue to exert, a strong influence on the standardisation of plant knowledge among rural populations in China. However, distinct local use of plants also exists, indicating that plant knowledge specific to the Bai people is alive and practiced.     

Hot and cold: Medicinal plant uses in Quechua speaking communities in the high Andes (Callejón de Huaylas,Ancash, Perú)

Ethno-pharmacological relevance

An ethnopharmacological survey has been set up in high altitude Quechua speaking communities dwelling in Callejón de Huaylas (Ancash department, Peru) and in medicinal plant markets in order to document the medicinal plants use of 178 species within the frame of a traditional Andean medicinal system.

Materials and methods

A sound ethnopharmacological survey was performed during the years 2011, 2012 and 2013 in different places along Callejón de Huaylas valley in the peruvian Andes, were Quechua speaking communities dwell. Two different methodologies were used: first, plant uses were recorded during walks with informants and in medicinal plant markets held on a regular bases in the area (Huaraz, Carhuaz, Yungay). Secondly, traditional healers (curanderas, curanderos) were interviewed about their practices and healing sessions were observed, in order to understand better the traditional medicinal system as a whole (disease aetiology, diagnosis, treatments, healers).

Results

Altogether, 178 medicinal species were collected. Most of the plants found on the market were also found in the wild and vice-versa. Medicinal plant trade is exclusively held by women, selling their merchandise to local people or to big retailer. Plants are classified according their hot or cold virtues, this in accordance with the local conception of the body physiology and disease aetiology, based on a hot–cold polarity. Main use notified for medicinal plants is “(bath) against cold”, a prophylactic measure against diseases of cold nature. Other uses include culture bound illnesses i.e. susto, aire, nervios, or heart pain, commonly cited in South America. Regarding symptoms, rheumatic/arthritic pain, musculoskeletal traumas, cough, pulmonary and respiratory problems, gastritis and stomach ache, were the most frequently cited. Diagnosis and treatment are intrinsically linked together and mainly based upon divination techniques using egg and cuy (Cavia porcellus L., Caviidae).

Discussion and conclusion

Medicinal plants use and traditional medicinal practices are still very vivid in Callejón de Huaylas as highlighted by the abundance of medicinal plants traded in the markets. In this business, women have a key position as healers at the family and community level. Medicinal uses of the majority of the species presented here are reported for the first time. Because medicinal plants sold on the market are collected from the wild and also because high altitude medicinal plants are generally small herbaceous species pulled out with their roots, there is a serious risk of over exploitation and extinction of endemic species.

Medicinal plant diversity and use in the highlands of Dolakha district,Nepal

This paper presents the ethnomedical uses of wild species among nine rural communities managing local forest resources in the Bonch Village Development Committee (VDC), Dolakha district, Nepal. Local communities possess knowledge of 113 medical remedies derived from 58 species belonging to 40 families to treat a wide range of ailments. A review of literature indicated that 56 medical remedies reported in this paper are new. Most medicines were prepared in the form of juice and were administered orally. Roots and leaves were the most frequently used plant parts. Local people were familiar mostly with the species dealing with common ailments particularly cough/cold, digestive problems, fever, headache, and skin infections. Complex ailments were treated by traditional healers. Haphazard harvesting and over-exploitation of commercial species were also reported. Sustainable harvesting methods and domestication of potential commercial species require attention in the local forest operational plans. The present study indicates that the area harbors a high diversity of medicinal plants. Despite gradual socio-cultural transformation, local communities still possess substantial knowledge of plants and their uses. The reliance on folk medicines for health care is associated with the lack of modern medicines and medication, poverty and the traditional belief of its effectiveness. Since there is a lack of phyto-therapeutic evidence for many of the species, we recommend that phytochemical and pharmacological studies be carried out in order to confirm the validity of properties attributed to these species: this is particularly relevant for species with market potential beyond the district. With setting up management plans for their extraction, these medicinal resources can provide for both subsistence needs and income. This, however, requires detail assessment of resource quantities, productivity potential, sustainable harvesting methods, domestication possibilities, market value of potentially promising species, and importantly, equitable benefit sharing regimes.

Medicinal plant diversity and uses in the Sango bay area, Southern Uganda

An inventory is presented for the medicinal plants of the Sango bay area in Southern Uganda. Fieldwork was conducted between March and August 2004, using semi-structured interviews, questionnaires and participant observation as well as transect walks in wild herbal plant collection areas. One hundred and eighty-six plant species belonging to 163 genera and 58 families with medicinal values were recorded. Remedies from these plants are prepared mainly as decoctions and infusions and administered in a variety of ways. The majority (51.3%) of these plants are herbaceous, growing mainly in the wild. Grasslands provided the highest number of species for medicinal use (54.6%) followed by home gardens (25.4%) and fallow land (19.5%). A review of Ugandan and other literature indicated that 72 (38.5%) medicinal plants reported in this study have not been reported previously as having medicinal value. According to respondents, plant species including Hallea rubrostipulata (K. Schum) J-F Leroy (Rubiaceae) and Warburgia ugandensis Sprague (Canellaceae) are threatened because of poor harvesting techniques and unsustainable harvesting intensities. Suggestions for future conservation programs, sustainable utilization and ethnopharmacological studies are given.
