          Abstract

          O objetivo desta pesquisa foi realizar levantamento etnobotânico sobre o conhecimento e uso de plantas medicinais por especialistas locais na comunidade do Lami, situada na região sul de Porto Alegre, Rio Grande do Sul. A metodologia envolveu a aplicação de entrevistas semi-estruturadas e excursões guiadas. Para cada citação as seguintes informações foram registradas: nome botânico e vernacular, uso terapêutico, parte da planta utilizada, preparação e forma de administração. Foi calculado o valor de uso e a porcentagem de concordância quanto aos usos principais corrigida para cada planta citada, bem como o fator de consenso entre informantes para as diferentes categorias de doenças consideradas. Registrou-se o conhecimento sobre 141 espécies medicinais, pertencentes a 63 famílias botânicas. O conhecimento dos especialistas é bastante amplo e inclui o uso de plantas nativas e exóticas quase na mesma proporção. As plantas medicinais representam uma importante alternativa terapêutica na comunidade estudada. O uso associado das medicinas tradicional e convencional, bem como as formas de transmissão e conservação do conhecimento são também discutidos neste artigo.

          The aim of this study was to conduct an ethnobotanical survey focusing on the knowledge and use of medicinal plants by local experts from Lami community, located in the south region of Porto Alegre, Rio Grande do Sul, Brazil. The methodology involved semi-structured interviews and guided excursions. For each citation the following data were recorded: botanical and vernacular name, therapeutic use, part used, preparation and administration form. The use value was calculated, as well as the corrected percentage of agreement concerning the main uses for each cited plant and the factor of consensus among informants for the different categories of the considered diseases. Knowledge about 141 medicinal species of 63 botanical families was recorded. The experts have an extensive knowledge including the use of native and exotic plants almost at the same proportion. Medicinal plants represent an important therapeutic option in the studied community. The associated use of traditional and conventional medicines, besides the forms of knowledge transmission and conservation are discussed in this paper.

            Medicinal plants in Mexico: healers' consensus and cultural importance.

            Medicinal plants are an important element of indigenous medical systems in Mexico. These resources are usually regarded as part of a culture's traditional knowledge. This study examines the use of medicinal plants in four indigenous groups of Mexican Indians, Maya, Nahua, Zapotec and - for comparative purposes - Mixe. With the first three the methodology was similar, making a direct comparison of the results possible. In these studies, the relative importance of a medicinal plant within a culture is documented using a quantitative method. For the analysis the uses were grouped into 9-10 categories of indigenous uses. This report compares these data and uses the concept of informant consensus originally developed by Trotter and Logan for analysis. This indicates how homogenous the ethnobotanical information is. Generally the factor is high for gastrointestinal illnesses and for culture bound syndromes. While the species used by the 3 indigenous groups vary, the data indicate that there exist well-defined criteria specific for each culture which lead to the selection of a plant as a medicine. A large number of species are used for gastrointestinal illnesses by two or more of the indigenous groups. At least in this case, the multiple transfer of species and their uses within Mexico seems to be an important reason for the widespread use of a species. Medicinal plants in other categories (e.g. skin diseases) are usually known only in one culture and seem to be part of its traditional knowledge.
