Medicinal utilization of exotic plants by Bapedi traditional healers to treat human ailments in Limpopo province,South Africa

Ethnopharmacological relevance

Most exotic plants are usually labelled as alien invasives and targeted for eradication. However, some of these exotic plants play an important role in the traditional primary healthcare sector of the Bapedi culture in the Limpopo Province of South Africa. The medicinal uses of most of these species have neither been documented nor their biological activity evaluated.

Aim of the study

To make an inventory of exotic species employed by Bapedi traditional healers to treat different human ailments in the Limpopo Province, South Africa.

Materials and methods

Semi-structured interviews, observation and guided field walks with 52 traditional healers were employed to obtain ethnobotanical data during first half of 2011 on the use of exotic plant species by Bapedi healers to treat human ailments. Based on ethnobotanical information provided by these healers, specimens were collected, numbered, pressed, and dried for identification.

Results

A total of 35 exotics species belonging to 21 families and 34 genera, mostly from the Fabaceae and Solanaceae (11.4% for each), Apocynaceae and Asteraceae (8.5% for each) were used by Bapedi healers to treat 20 human ailments. Trees (45.7%) and herbs (37.1%) are the primary source of medicinal plants. Species most frequently reported were used for the treatment of hypertension (35%), diabetes mellitus, erectile dysfunction and gonorrhoea (25% for each). The highest consensus from individual accounts of the traditional healers on the use of exotic plant remedies in this study was noted for the three ailments. These were for Catharanthus roseus (gonorrhoea, 60%), Punica granatum (diarrhoea, 38.4%) and Ricinus communis (sores, 21.5%). Of the 35 exotic plant species recorded, 34.2% are regulated by the Conservation of Agricultural Resources Act (1983) (CARA) No. 43 of 1983 either as worst weeds or invaders.

Conclusion

The present study demonstrated that exotic plant species play an important part as medicinal remedies employed by Bapedi healers to treat different human diseases in the Limpopo Province. The use of these species as alternative sources of medicinal remedies could alleviate harvesting pressure of wild indigenous plants, thereby enhance biodiversity's region. However, there is a need to formulate an appropriate policy to retain some of the useful medicinal exotics (listed under CARA No. 43 of 1983) within the environment before their medicinal value vanishes as they are eradicated through management strategies adopted by the South African government.

Ethnopharmacological survey of medicinal plants used by indigenous and tribal people in Rangamati,Bangladesh

Ethnopharmacological relevance

There is very limited information regarding plants used by traditional healers in Rangamati, Bangladesh, for treating general ailments. Current study provides significant ethnopharmacological information, both qualitative and quantitative on medical plants in Rangamati.

Aim of the study

This study aimed to collect, analyze and evaluate the rich ethnopharmacologic knowledge on medicinal plants in Rangamati and attempted to identify the important species used in traditional medicine. Further analysis was done by comparison of the traditional medicinal use with the available scientific literature data.

Materials and methods

The field survey was carried out in a period of about one year in Rangamati, Bangladesh. A total of 152 people were interviewed, including Traditional Health Practitioners (THPs) and indigenous people through open-ended and semistructured questionnaire. The collected data were analyzed qualitatively and quantitatively. This ethnomedicinal knowledge was compared against the literature for reports of related uses and studies of phytochemical compounds responsible for respective ailments.

Results

A total of 144 species of plants, mostly trees, belonging to 52 families were identified for the treatment of more than 90 types of ailments. These ailments were categorized into 25 categories. Leaves were the most frequently used plant parts and decoction is the mode of preparation of major portions of the plant species. The most common mode of administration was oral ingestion and topical application. Informant consensus factor (Fic) values of the present study reflected the high agreement in the use of plants in the treatment of gastro-intestinal complaints and respiratory problems among the informants. Gastro-intestinal complaint had highest use-reports and 3 species of plants, namely Aegle marmelos (L.) Corr., Ananas comosus (L.) Merr., and Terminalia chebula (Gaertn.) Retz., had the highest fidelity level (FL) of 100%. Asparagus racemosus Willd. and Azadirachta indica A. Juss. showed the highest relative importance (RI) value of 1.86. According to use value (UV) the most important species were Azadirachta indica A. Juss. (2.48) and Ocimum sanctum L. (2.45).

Conclusion

As a result of the present study, we recommend giving priority for further phytochemical investigation to plants that scored highest FL, Fic, UV or RI values, as such values could be considered as good indicator of prospective plants for discovering new drugs. Also counseling of THPs should be taken into consideration in order to smooth continuation and extension of traditional medical knowledge and practice for ensuring safe and effective therapy.     

Plant genetic resources and traditional knowledge on medicinal use of wild shrub and herbaceous plant species in the Etna Regional Park (Eastern Sicily,Italy)

Ethnopharmacological relevance

This paper illustrates the results of a study carried out in the Etna Regional Park (Eastern Sicily, Italy) concerning the traditional knowledge on medicinal use of wild plant species. It contains the results of a quantitative analysis carried out for the first time. A total of 71 wild species are used for medicinal purposes. Two species, Astracantha sicula (Biv.) Greuter and Trifolium phleoides Willd., are little known as medicinal in the Mediterranean area. The main aim of the study was to understand to what extent current knowledge on the medicinal use of plants is still an element of the culture within the elderly population of the Etna Regional Park. A further aim was to identify species not previously reported as medicinal in the Mediterranean area with a potential agricultural interest.

Methodology

The information was obtained using a semi-structured interview format performed on a sample of 196 people over the age of 60 who were considered experts in rural traditions. The plant uses were compared with other medical-ethnobotanical studies carried out in other areas of Sicily, Italy and various other Mediterranean countries. A number of quantitative indices were also used in order to verify the incidence of the species cited in the study within the culture and traditional medicine.

Results

Local communities currently use a total number of 71 wild species (34 families) as remedies for medicinal purposes. Most of the species were used as treatments against metabolic disorders and for general health. The leaves and the aerial parts of plants are the most-used parts of the plant and the most common preparation methods are decoction and direct application of plant parts. Astracantha sicula and Trifolium phleoides have never been documented as a species with medicinal properties in the Mediterranean literature.

Conclusions

Only very few medicinal uses are widely known by all the informants and, on many occasions, a specific medicinal use is cited by only very few people. The quantitative analysis shows that the level of traditional knowledge on medicinal use of plants in the study area is poor, highlighting a considerably advanced state of cultural erosion.

Quantitative ethnobotany of medicinal plants used by Kara and Kwego semi-pastoralist people in lower Omo River Valley,Debub Omo Zone,Southern Nations,Nationalities and Peoples Regional State,Ethiopia

Aim of the study

The people in Ethiopia have been using medicinal plants over centuries and the traditional knowledge is passed verbally from generation to generation. Therefore, the aim of this study was to document the medicinal plants used by Kara and Kwego semi-pastoralist people and to establish association between the species richness and diversity, habit, parts used and administration of medicinal plants reported by the two people.

Materials and methods

Semi-structured interview was used in data collection; Chi-Square test, t-test and univariate analysis were used to compare medicinal plants knowledge between Kara and Kwego people. Informant consensus factor (ICF), fidelity level (FL), and preference ranking of medicinal plants were computed.

Results

Fifty-seven medicinal plant species were indicated that were distributed into 33 families and 52 genera. Thirty-four of them were common to both people whereas 12 were unique to Kara and 11 to Kwego. There was no significant difference (p > 0.05) between the two people in medicinal plant species richness and diversity. The growth forms, parts of medicinal plants and their conditions: fresh or dry used in the preparation of remedies and route of administration were not different (p > 0.05). Root was 55% of the plant parts used and oral was 61% of route of administration. The informant consensus factor was not significantly different (p > 0.05) between the two people. Solanum hastifolium Hochst. ex Dunal, Salvadora persica L. and Maeura sessiliflora Gilg were preferred more than the other medicinal plants reported to treat the prevalent diseases by both people.

Conclusions

The information documented on the medicinal plants of these people may be used as baseline data for future studies on semi-arid and arid pharmacologically important medicinal plants and for phytochemical investigations.
