          Abstract

          Resumen Existe una relación estrecha del hombre con los recursos naturales, en especial con las plantas, para aliviar algunas enfermedades. El estudio se realizó con el objetivo de registrar las plantas medicinales y sus usos en la zona metropolitana de Saltillo, Coahuila. Un total de 113 informantes (17 hombres y 96 mujeres, de 20 a 70 años) fueron entrevistados a través de un formato etnobotánico semiestructurado dividido en aspectos socioeconómicos y conocimiento tradicional de plantas medicinales. El reporte de usos obtenido se dividió en 13 categorías basadas en las Clasificación Estadística Internacional de Enfermedades y Problemas de Salud de la Organización Mundial de la Salud. Se registró un uso promedio de 4.6 plantas y cinco usos por planta. Las mujeres registraron 4.9 plantas y los hombres 3.1. El análisis de regresión, mostró correlación positiva entre edad y número de planta. Se registraron 82 plantas para tratamiento de enfermedades distribuidas en 37 familias botánicas. Las enfermedades más comunes son las que afectan el sistema respiratorio, gastrointestinal y nervioso. Las especies con mayor Índice de Valor de Uso fueron: Matricaria recutita (IVU = 0.65) y Litsea parvifolia (IVU = 0.35). Las familias más representativas fueron Asteraceae (10 especies, 125 reportes de uso), Lamiaceae (12 especies, 119 RU) y Lauraceae (cuatro especies, 64 RU). Las formas de preparación más comunes fueron: infusión (88.6%) y emplasto (3.68%). Aunque no existe un arraigo étnico ni cultural, los pobladores de la zona metropolitana recurren al uso de remedios herbolarios, fomentando el conocimiento a través de sus usos y forma de consumo.

          Abstract A close relationship exists between man and natural resources, especially plants, to alleviate some diseases. The study was carried out with the objective of registering medicinal plants and their uses in the metropolitan area of Saltillo, Coahuila. A total of 113 informants (17 men and 96 women, aged 20 to 70) were interviewed through a semi-structured ethnobotanical format divided into socioeconomic aspects and traditional knowledge of medicinal plants. The report of uses obtained was divided into 13 categories based on the International Statistical Classification of Diseases and Health Problems of the World Health Organization. An average use of 4.6 plants and five uses per plant was recorded. Women recorded 4.9 plants and men 3.1. The simple regression analysis shows a positive correlation between Age and Plant Number. A total of 82 plants were recorded to treat diseases, belonging to 37 botanical families. The most common diseases are those that affect the respiratory, gastrointestinal, and nervous systems. The medicinal species with the highest Use Value Index were: Matricaria recutita (IVU = 0.65) and Litsea parvifolia (IVU = 0.35). The most representative families were Asteraceae (10 species, 125 use reports), Lamiaceae (12 species, 119 RU), and Lauraceae (four species, 64 RU). The most common form of preparation was infusion (88.6%) and poultice (3.68%). Although there are no ethnic or cultural roots, the residents of the metropolitan area resort to the use of herbal remedies, promoting knowledge through their uses and forms of consumption.

            Traditional knowledge on medicinal and food plants used in Val San Giacomo (Sondrio, Italy)--an alpine ethnobotanical study.

            This work increases the ethnobotanical data from Northern Italy and, in particular, the Lombardy region, till now poorly documented, safeguarding the local folk knowledge, and provides information on new or scarcely reported properties of medicinal plants, whose traditional use needs to be validated experimentally. The present study aimed to gather, analyse and evaluate the ethnobotanical information on the species used for medicinal and food purposes by the native people of Val San Giacomo. The plant use was documented by speaking with more than 100 people, mainly over 60 years old, born and resident in Val San Giacomo. Information was collected using semi-structured interviews and then analysed by indices such as Ethnophytonomic Index (EPI), Ethnobotanicity Index (EI), relative frequency of citation (RFC), use value (UV), relative importance (RI) and factor informant consensus (FIC). Information on 66 plants belonging to 35 families (Asteraceae, Rosaceae and Lamiaceae, mainly) was gathered. The preference ranking placed Achillea moschata Wulfen at first place, both for the citation number and for RFC and UV. Arnica montana L., Thymus pulegioides L. and Artemisia genipi Stechm. were also in relevant use. Sixty species were wild and six were cultivated. Leaves, flowers, complete aerial parts and fruits were the plant parts most commonly used for remedy preparation (infusion, especially). The interviewees collected local flora for medicinal purposes, specifically. About 51.5% of the plant species were used to treat gastrointestinal tract of humans as digestive, depurative, appetiser, laxative, astringent and carminative remedies. About 56% of the plants were used in cookery, 24.2% in veterinary field, and 3% as cosmetics. The calculated indices demonstrated that in the studied area there is a small retention of plant knowledge. Only 6.2% of the autochthonous plants proved useful in folk tradition. Despite this, the uses of Sempervivum montanum L., Rhododendron ferrugineum L. and Panicum miliaceum L. were never documented by other ethnobotanical investigations conducted in the alpine area. This survey was an extension of the ethnobotanical investigations performed in the Italian Alps. A study like this, though performed in a small area with a reduced traditional knowledge, could be the basis for subsequent research on the species that are interesting from a phytochemical point of view and on the potential use of their active metabolites.

              Ethnopharmacological field studies: a critical assessment of their conceptual basis and methods.

              Ethnopharmacology as a well-defined field has a relatively short history, but for centuries researchers have been interested in the observation, description, and experimental investigation of indigenous drugs and their biological activities. Today, such articles are published in a variety of journals among which the Journal of Ethnopharmacology has a prominent position as well as in book monographs. As any other area of scientific endeavour, this field requires a critical and engaged discussion about the conceptual basis, the relevant methods and the overall standards necessary for excellence. Here we review recent ethnopharmacological field studies in order to highlight achievements and future needs for improving the quality of such studies. The basis for this review is 40 field studies published in the years 2007 and 2008 in the Journal of Ethnopharmacology. Researchers need to have a clear vision for what and how they want to achieve a conceptually and methodologically sound approach and as in all disciplines adherence to internationally recognized methodological standards is essential. Here we review not only the basic conceptual requirements but also the minimal methodological (i.e. botanical, anthropological/historical,ethnomedical) standards and ways how to quantify ethnopharmacological information. Future uses of such information both in the context of experimental research and in applied projects highlight the multiple roles of such data generated in ethnopharmacological field studies. This review cannot be a book of recipes on how to conduct such research but highlights minimal conceptual and methodological requirements for use in future projects.
