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.     

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.     

Traditional use of the native medicinal plant resource of Mt. Rtanj (Eastern Serbia): Ethnobotanical evaluation and comparison

Ethnopharmacological relevance

This study reports on the uses of medicinal plants and ethnobotanical significance of Mt. Rtanj, Eastern Serbia. The aim of the study was collecting information on plant utilization and creating the list of medicinal plants collected by local community in the region of Rtanj Mt. in Serbia.

Methodology

A group of generally elderly people from the region were interviewed, asked to identify a certain number of plant taxa used against various human ailments. A quantitative ethnobotanical comparison has been performed in relation to other studies concerning the central Balkan Peninsula.

Results

There is an inventory of 45 plant species recorded. At the family level, the most common in traditional usage were species of Labiatae (22%), Rosaceae (20%) and Compositae (13%). The results of the survey suggested that Hypericum perforatum was the most popular medicinal plant. Among the 7 different recorded types of preparation, the aerial parts of plants were the most popular (47.3%). The most frequently reported medicinal uses of herbal drugs include remedies for immune system (22.97%), respiratory system (15.77%) and digestive system disorders (15.32%). However, a comparatively small number of available plant species was used for medicinal purposes while the level of ethnobotanical diversity was lower when compared to adjacent regions.

Conclusions

Ethnobotanical knowledge in this area is decreasing due to high emigration rates during the last period. The historically developed ethnobotanical heritage should be preserved and promoted on the larger level, getting the special position in the future management plans for this area.     

Ethnobotanical uses of medicinal plants in the highlands of Soan Valley,Salt Range,Pakistan

Ethnopharmacological relevance

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.

Ethnobotany of medicinal plants used in Eastern Mallorca (Balearic Islands, Mediterranean Sea)

Ethnopharmacological relevance

This paper represents the first large-scale ethnobotanical study in the island of Mallorca, and provides significant information on pharmaceutical plant uses, built up from interviews with native people from this touristic hotspot, demonstrating its ethnopharmacological importance.

Aim of the study

To collect, analyse and evaluate the ethnobotanical knowledge concerning medicinal plants in a north-eastern Mallorcan area (municipalities of Artà, Capdepera and Son Servera; 298 km², 31,764 inhabitants).

Materials and methods

We performed semi-structured interviews with 42 informants (mean age 77; 40% women, 60% men), identified the plant taxa reported and analysed the results, comparing them with those found in the current Mallorcan ethnobotanical information and in other territories.

Results

The informants reported data on 121 human medicinal plants representing 64 botanical families. Around 45 medicinal uses reported, concerning 37 species, have not or have very rarely been cited as medicinal. An index of medicinal importance is proposed.

Conclusions

All efforts addressed to compiling ethnobotanical information in industrialised or touristised areas such as Eastern Mallorca are still valuable. New possibilities can be explored to give practical value to Mallorcan ethnobotanical data in the frame of considering traditional plant knowledge as part of the islanders’ lifestyle and healthy habits.
