The traditional knowledge can be defined as to know and knowing to make, regarding the natural and supernatural world, generated in the scope of the not urban society/verbally transmitted industrial and of generation in generation. One of the approaches that more contribute to study the knowledge of the traditional populations is the etnocincia, that has left of the linguistics to study the knowledge of the populations human beings on the natural processes, trying to discover underlying logics to the human knowledge of the natural world. Berkes & Folke (1998), uses the term traditional ecological knowledge to mention to a cumulative body of knowledge and beliefs, passed between the generations for cultural transmission, on the relation of the existence of its life (including human being), with other factors and its environment. The same authors use the traditional word to relate historical and cultural the continuity, recognizing that the society is constantly redefining what is considered ‘ ‘ tradicional’ ‘. The etnoecologia she is one disciplines in charge studying the conceptions, perceptions and knowledge on the nature, that the agricultural societies allow to produce and to reproduce the material conditions and spirituals of its social existence in the handling of its natural resources or ecosystems (TOLEDO, 1992). The same author standes out the forms of appropriation and creation of knowing of the populations regarding its natural environment, observing systems of knowledge of the natural world established by these productive practical populations and its. Batistella et al (2005), standes out that it is necessary to recognize the existence, between the traditional societies, of other forms, equally rational to perceive biodiversity, beyond the offered ones for modern science, considering that this knowledge assures the fast access the elementary information for scientific research, beyond giving subsidies to the local population in the defense of ‘ ‘ its lugar’ ‘. I begin it, the use of these products was established only in the popular knowledge passed of generation for generation.
However with passing of the years these knowledge come gaining each time more scientific character and this has only enriched the armory pharmaceutical and proven the veracity of the popular wisdom. Kupchan (1971) apud Ribeiro (1987), standes out is unquestionable that the natural products come contributing and very with the development of the pharmaceutical armory and the medical clinic in its diverse specialties. However what it calls attention for dangerous a curious situation and at the same time: the popular fact of the same plant to possess one or more names or of different plants to possess name the same. It is not something How much is kind worth would like to discuss. This cause confusion, from there the necessity of if knowing the plant well used, therefore many still can possess unknown toxic effect. Therefore the plants must be acquired of laboratories or people (razeiros etc) idoneous this guarantees quality and correct identification. The vegetable use for medicinal ends is old and comes more if accenting each time which had the deficiency of the health system, whose access presents diverse difficulties, between them the interminable lines to obtain a consultation and the high price of medicines (VIEIRA, 2003). In this direction the popular medicine is a natural and accessible alternative in such a way in the search of the definitive cure how much in the relief of momentneas pains. Therefore many are the populations that possess in its houses the calls medicinal yards, this custom are present mainly in old communities that still today preserve its traditions.
