Plantas medicinales utilizadas por una comunidad Mapuche en las cercanías de Junín de los Andes, Neuquén

ABSTRACT Se comparó el uso de plantas medicinales en la comunidad Mapuche Painefilú utilizando dos metodologías etnobotánicas: entrevistas individuales y un taller participativo. Se trabajó con el 67% de la población, registrándose un total de 42 especies. Las más citadas fueron: ajenjo (Artemisia absinthium), nalca (Gunnera tinctoria), ñanculahuén (Valeriana carnosa) y carqueja (Baccharis trimera). Las plantas citadas con ambas metodologías se asemejaron en un 41 %. Los efectos más reportados en las entrevistas fueron: digestivos (39%), analgésicos (20%) y síndromes de filiación cultural (8%), siendo éstos últimos los más frecuentemente citados en el taller (30%). Este trabajo pone de manifiesto la importancia de complementar distintas metodologías en este tipo de estudios

    • "En el uso contra las dermatitis, la decocción puede combinarse con Erodium cicutarium (L.) L'Hér. ex Aiton ( " alfilerillo " ), una reconocida planta medicinal vulneraria (Martinez Crovetto 1980), y acompañarse con la toma de una infusión de Ribes magellanica Poir ( " parrilla " ), también de virtudes vulnerarias, anti-inflamatorias y analgésicas (Estomba et al. 2005; Meza & Villagrán 1991). La cantidad que habitualmente se prepara es de uno a dos litros, para lo cual se utilizan dos o tres ramas enteras, de aproximadamente 30-40 cm de longitud. "

    ABSTRACT: Baccharis obovata Hook. et Arn. is an aromatic species known as "wautro", and is an important part of the Mapuche herbolarium of Patagonia Argentina. The objectives were to investigate its ethnobotany and shoot anatomy, as well as to characterize physically and chemically its essential oil. Rural informant-interviews were conducted in two Mapuche communities of Northwestern Patagonia, Argentina. In addition, we collected plant material for observation at optical and scanning environmental microscope, and for hydro-distillation of essential oil. Informants cited with a high level of consensus that this plant is principally used for hair loss, dandruff, some dermatitis, and headaches. The main leaf features were: isobilateral mesophyll, anomocytic stomata, glandular and pluricellular trichomas and squizogen cavities that secrete essential oils. Primary stem presented trichomas and secretory cavities similar to those of the leaves, collenchyma in ribs, chlorenchyma in valleys interrupted by air spaces, continuous vascular cylinder, uni-seriated and by sectors bi-seriated endodermis, discontinuous sclerenchyma, and acicular crystals in peripheral marrow cells. In terms of its essential oil, annual average yield, optimum time for distillation, relative density, specific rotation and refractive index was also obtained. B. obovata is an interesting cosmeceutical species, this work contributes to its general knowledge providing useful information for future quality control tasks, in addition to its bio-cultural conservation.

    ABSTRACT: This paper aimed to present a quantitative review of information on Mapuche ethnobotany published for Argentina and Chile in the period 1955-2007. Sixteen ethnobotanical articles were studied quantitatively by utilizing ethnobotanical indices, non-parametric and multivariate tests. A total of 505 medicinal species, 304 native (60%) and 196 exotic (39%) were registered. Ailments were treated with both native and exotic species, although native showed higher values of consensus (between studies) than exotic, and were more frequently used in all cases. The most common ailments were gastro-intestinal pains (26%). Most cures used herbs (56%). Native species were obtained mainly by gathering in forests and ecotones (40%), and exotics by gathering in anthropogenic environments (28%). Our results demonstrate the existence of a common, shared body of knowledge of the medicinal flora at a regional level, integrating ancestral knowledge with foreign knowledge accumulated over time. Finally, reflecting cultural erosion, modern articles cited significantly fewer native plants than older articles; a trend not found with exotic species. The information offered can be used as a guide for future work on promising species for health care, and as background information for the development of bio-cultural conservation strategies.

    ABSTRACT: En 9 poblaciones rurales pertenecientes a tres regiones de Córdoba, Argentina fue estudiado el uso de plantas medicinales. Mediante 192 encuestas (80-100% de la población de cada comunidad) fue descrito el uso de 120 plantas medicinales, considerando aspectos botánicos, diversidad de especies, usos, criterios de selección e identificación y pautas culturales asociadas. También se analiza el uso según edad y género. Se concluye acerca de la importancia de las plantas medicinales en el sistema etnomédico, se señalan las diferencias en el uso y su relación con los roles sociales, alertando acerca de la necesidad de revalorizar estos recursos como una alternativa de conservación.
