Descripción
This work compiled Brazilian articles regarding medicinal plant use by local communities in order to analyze the most common sampling problems and if research characteristics can influence on the presence of sampling irregularities. We focused on studies about medicinal plants that exhibit a species-indications list and had a quantitative nature. The proportion of works with and without sampling problems was evaluated considering the journal impact factor, period of publication, community status(urban x rural), type of sample, presence of hypothesis testing and presence of research questions. We found that an alarming proportion of papers had some kind of sampling problems (48.39% serious and 19.35% moderate). The most common problems were related to: lack of information regarding the sample size or the universe, small sample sizes and selection of specialists based on obscure criteria. We could not find a significant influence between our tested variables and the occurrence of sampling problems, except for the community status (urban x rural). Results indicate that a significant amount of intracultural diversity is not being properly captured, considering both the population as a whole and a group of interest in the community (e.g. healers).
