Abstract
BACKGROUND: Individuals develop crucial survival knowledge in the juvenile phase, including understanding medicinal plants. The family context or contact with resources can influence this dynamic knowledge. By investigating the influence of these factors on young people's understanding of medicinal plants, we aimed to enhance our understanding of the knowledge-building process. METHODS: The study was conducted in three communities in the State of Alagoas, Brazil: Lagoa do Junco, Serrote do Amparo, and Brivaldo de Medeiros. Semi-structured interviews were conducted with young people aged between 11 and 19 to assess their knowledge of medicinal plants. We used a generalized linear mixed model (GLMM) with the number of therapeutic targets and known medicinal species (knowledge proxy) as response variables. As predictors, we included the number of individuals per family unit and the gender distribution within the famimunícpily (family context proxy), as well as dependence on the use (contact proxy). Location (city) was added as a fixed effect to the model. We investigated how knowledge of medicinal plants correlates with the practice of collecting these species. RESULTS: We did not identify a relationship between the number of individuals per household, gender distribution within the family, and the frequency of medicinal plant use with knowledge about these species. However, we observed a positive, albeit weak, correlation between knowledge of medicinal species and the number of species collected. CONCLUSION: These results highlight the importance of investigating how young people acquire knowledge about medicinal plants, emphasizing the complex interactions between humans and nature, and providing a basis for future research.
