Quantifying medicinal plant knowledge among non-specialist Antanosy villagers in southern Madagascar.

摘要

Medicinal plant knowledge among non-specialist Antanosy villagers of southeastern Madagascar was investigated in a two-stage study. First, free-listing was used to collect the names of medicinal plants most familiar to local people. Data were organized by habitat and frequency into a short list of the 42 most frequently listed plants by habitat. A second group of interviewees were asked to name health conditions that could be treated with plants on the short list. Age, gender, and dwelling proximity to the forest were tested across the general habitat in which medicinal plants were found: in or near the village, in disturbed buffer areas between the village and the forest, or in the forest itself. Neither age nor gender was significant in free-listing. Naming health conditions treated with specific plants showed that knowledge increases with age and that for all but the oldest age group, women knew more plant uses than men. Women knew more plants from the village and buffer areas, and fewer from the forest than men. The proximity of the home to the forest had no influence on medicinal plant knowledge. The non-specialists interviewed named an average of 14 medicinal plants and most knew an average of 37 uses for 9 of the 42 most common medicinal plants. The most common conditions for people knew of plant treatments were stomach ache, babies' fevers, and several unlisted conditions. Both exotic and endemic plant species were known to the non-specialists indicating that medicinal plant knowledge is being sustained and adapted to changes affecting both the people and their environment.Digital Object Identifier http://dx.doi.org/10.1007/s12231-011-9185-9
