Two thirds of the world’s population relies on medicinal plants for centuries for several human pathologies. Present study aimed to identify, catalogue and document the large number of medicinal plants used in traditional medicine in Soan Valley, Salt Range, Pakistan.

Materials and methods

Informal interviews were conducted involving a total of 255 villagers (155 male and 65 female and 35 herbalists) to elicit the knowledge and use of medicinal plants.

Results

Local communities possessed knowledge of fifty eight (58) medicinal plant species belonging to thirty five (35) families to treat fifteen ailment categories. Whole plant and leaves were the most frequently used plant parts (24%) followed by seed (14%), root (12%), flower (7%), bulb (6%), fruit (4%), stem (3%), latex and rhizome (2%) and sap and gum (1%). Frequently used growth forms of medicinal plants were wild herbs (63%) followed by cultivated herbs (14%), wild trees (11%), wild shrubs (10%) and wild and cultivated herbs (2%). Preparations were administrated generally through oral and topical routes. Local people were familiar mostly with the species in order to deal common ailments particularly cough, cold, digestive problems, fever, headache, and skin infections. Complex ailments were treated by traditional healers. Justica adhatoda, Olea ferruginea, Amaranthus viridis and Mentha royleana were identified as plants with high use value (UV).

Conclusions

This study revealed that the area harbors high diversity of medicinal flora. Despite gradual socio-cultural transformation, local communities still hold ample knowledge of plants and their uses. The reliance on traditional medicines was associated with the lack of modern health care facilities, poverty and the traditional belief of their effectiveness. Medicinal plants play a significant role in management of various human diseases in the study area. A high degree of consensus among the informants was an indicative that plant use and knowledge were still strong, and preservation of this knowledge showed good foresight in the future. Awareness was thus needed to be raised among local people on sustainable utilization and management of plant resources.

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.

Traditional uses of medicinal plants against malarial disease by the tribal communities of Lesser Himalayas–Pakistan

Ethnopharmacological relevance

Malaria is among the most prevalent infectious diseases in the developing countries of world. Estimated number of annual malaria episodes in Pakistan is 1.5 million, but very little is known about medicinal plant species of Pakistan, which have great potential against malarial disease. Present study was aimed to document medicinal plant species used by the local inhabitants of Lesser Himalayas–Pakistan to treat malaria.

Materials and methods

Data were collected through interviews, questionnaires and contributor observation. A total of 55 informants aged between 25 and 80 years who were familiar with malarial disease participated in the survey.

Results

A total of 84 plant species belonging to 69 genera and 50 families were recorded to treat malaria. Asteraceae was found as most cited botanical family with (11.9%) representation, followed by Lamiaceae (5.9%), Solanaceae and Verbenaceae (4.7%) and Violaceae (3.5%) respectively. About 60% of the inhabitants prefer herbal treatment by local herbalists or self-treatment with locally available medicinal plant species. Of the plants identified during present investigation against malaria, Azadirachta indica, Swertia chirayita and Swertia ciliata exhibited uppermost frequency of encounter (36.3%) and corresponding PR value 5. About 67.2% of the botanical taxa are reported for the first time in the treatment of malaria. It was observed thatover harvesting is the foremost threat to medicinal plant species of the study area.

Conclusion

Present survey indicates that traditional knowledge about the use of plant species against various diseases and particularly to treat malaria is in decline. Similarly anthropogenic pressure, over exploitation and grazing of the botanical taxa are the major concerns regarding medicinal plant biodiversity loss. Frequently utilized plant species with significant malarial reduction should be authenticated by in vitro and in vivo standard tests     

Medico-religious plants used by the Hajong community of Assam,India

Ethnopharmacological relevance

The Hajong people use many medicinal plants in their different rituals. The information generated from the present study regarding the medico-religious plants used by the Hajong tribes need a thorough phytochemical investigation. This could help in creating awareness regarding the need for conservation of such plants and also in the promotion of ethno-medico-botany knowledge within the region besides contributing to the preservation and enrich- ment of the gene bank of such economically important species before they are lost forever. Medico-religious plants so found out in this study should be screened for their efficacy by which new drugs or products could be brought out. There is also need to document this information and compare with that of other tribes in the state and region.

Materials and Methods

The diseases found during the research work among the Hajong community were grouped in 11 categories. The category of diseases includes plants used for both human and animal diseases. The informants having good knowledge on medico-religious plants were chosen for the interview. Kabiraj or Vaidyas were also included among the informants though they were not available in all villages. The informants were asked about the ritual and religious importance and the medicinal properties of the plants used in different cultural practices.

Results

Some 36 plant species including herbs, shrubs and trees are used for curing 51 different diseases with 63 formulations which are recorded during the study. Most of the medicinal plants were collected from their own homestead and rest from the forest. Hajongs make sustainable use of available natural resources that include both medicinal and religious plants. They lead a much disciplined life. They are very much religious and knowledgeable. The survey revealed that not only the Kabiraj but also the elder community member have good knowledge of the medicinal value of some plant usually those species used to treat common diseases like cough, cold, fever, viral fever, headache, stomachache, joint pain, diarrhea, dysentery, minor wounds and cuts etc. Thus 36 plants are found to be used by Hajong in different medico-religious practices. These are regarded as holy plants. These plants are strictly protected by the community. Traditional conservation and management on cultural grounds, therefore, represents a historic contribution to the present day rich biodiversity in the region.

Conclusion

The whole life system and socio-economic as well as religious and cultural activities of Hajongs were totally dependent upon forests. It reflected their high possession of knowledge on medico religious plants which allowed them to apply their indigenous knowledge regarding various aspects of exploitation of such resources. Different types of important species have been disappeared from the study area, which ultimately creates social, economical and religious problem in Hajong community. The information generated from the present study regarding the medico-religious plants used by the Hajong tribes need a thorough phytochemical investigation. This could help in creating awareness regarding the need for conservation of such plants and also in the promotion of ethno-medico-botany knowledge within the region besides contributing to the preservation and enrichment of the gene bank of such economically important species before they are lost forever. Traditional culture in different Hajong populated areas is very fast declining with lot of traditional knowledge under the influence of dominant culture. Cultural diversity conservation is needed urgently.

To collect, analyze and evaluate the ethnobotanical knowledge about these medicinal plants in the Sinai Peninsula region with 61,000 km² and 379,000 inhabitants.

Methodology

Field work was concluded between March 2006 and May 2011, using semi-structured questionnaire with 700 informants (mean age: 59; 100% men) from 117 settlements of 17 Bedouin tribes. Transects walks in wild herbal plant collection areas and bibliographical review on the collected plants were also conducted. The Interview/ Inhabitant index (I/P), relative importance value of the species and informant consensus factor (FIC) were calculated.

Results

More than 300 species were traditionally used in folk medicine in the Sinai Peninsula; 101 of these species belonging to 40 families were reported as useful in different CNS disorders. Only 5 species are endemic of the studied area. All different part plants were used, leaves and aerial parts being the most frequent. Most of the remedies were prepared as infusion or decoction, while oral administration was the most common way to be used. Gastrointestinal (67.3%) and respiratory disorders (42.57%) were also reported as frequently treated by Bedouins with herbal remedies.

Conclusions

Only a few species were found where the traditional use is supported by pharmacological studies (Acacia nilotica, Achillea fragrantissima, Ajuga iva or Mentha longifolia). No bibliographical references in the scientific literature were found for 22 species (21.78%); finally, several studies were published with different pharmacological activities than those provided by Bedouins.

Around 800 medicinal uses, concerning 200 species, have not, or have very rarely been cited as medicinal; of these, 32 uses of 30 species have been reported by three or more independent informants.

Conclusions

The folk knowledge about medicinal plant use is still alive in the studied region, and a number of scarcely reported plant uses has been detected, some of them with promising phytotherapeutical applications.     

Traditional knowledge on medicinal plant of the Karen in northern Thailand: A comparative study

Ethnopharmacological relevance

We studied traditional medicinal plant knowledge among the Karen in northern Thailand.

Aim of the study

To compare traditional medicinal knowledge in 14 Karen villages in northern Thailand and determine culturally important medicinal plant species in each Karen village.

Materials and methods

We interviewed 14 key informants and 438 non-specialist informants about their traditional knowledge of medicinal plants. We tested normality of the data and correlations with distance to the nearest city using Kolmogorov–Smirnov tests and Spearman's rank correlation coefficient. Cluster analysis and cultural importance index (CI) were calculated for the similarity of medicinal plant used and culturally importance medicinal plant species among Karen villages respectively.

Results

In total 379 medicinal plant species were used. Number of medicinal plants used positively correlate with distance to the nearest city. Relatively low similarities of medicinal plant species and different CI values for species among the different areas were found.

Conclusions

Traditional medicinal plants still play an important role in medicinal practice of the Karen. Local environments, availability of medicinal plant and distance between Karen villages and the nearest city affect the amount of traditional medicinal knowledge in each Karen village. The medicinal plants in this study with high CI values might give some useful leads for further biomedical research.

Our study presents results of an ethnobotanical inventory conducted to identify and document medicinal and nutritional plants used in the management of opportunistic infections associated with human immunodeficiency virus / acquired immunodeficiency syndrome (HIV/AIDS), the plant parts used, preparation and administration methods of herbal remedies.

Materials and methods

We performed semi-structured interviews with 79 respondents (women 78%, men 22%), who included specialists in medicinal plants (such as traditional birth attendants and herbalists) and non specialists with general knowledge of plant use. Respondents answered a semi-structured questionnaire regarding their knowledge of plants and general treatment practices including management of HIV/AIDS opportunistic infections. The reported plants were collected and identified. Data were analyzed using factor informant consensus and fidelity level to determine homogeneity of informants? knowledge on medicinal and nutritional plants suitable for different ailment categories and the most preferred plant species used to treat each ailment category in the study areas.

Results

The study revealed 148 plant species belonging to 54 families, most of which were herbs (50.7%). Leaves (61.6%) were the most frequently used parts in remedy preparations which were mainly administered orally (72%). The majority of plants (62%) were harvested from wild habitats. The most important species according to fidelity values are Hibiscus sabdariffa L. for anaemia, Mangifera indica L. for cough, Zehneria scabra (L. F.) Sond. for skin infections, Rhus natalensis Bernh.ex.Krauss for diarrhoea and Tarenna pavettoides (Harv.) Sim for appetite boosting. The factor informant consensus highlighted the agreement in the use of plants and showed that the respiratory infections category had the greatest agreement (0.60). Family Asteraceae accounted for 15% of the total species recorded. Sixty plant species (40%) of the plants provide nutritional support.

Conclusion

The study revealed that folk medicine is still widely practised. Fidelity level values indicate that these plants are the most preferred species for particular ailments. The high consensus value (0.6) indicated that there was high agreement in the use of plants for respiratory ailments among others. These preferred plant species could be prioritized for conservation and subjected to chemical screening to ascertain their pharmacological activities.
