Ethnobotanical Survey of Medicinal Plants: Knowledge, Use and Origin

Abstract

Medicinal plants play an important role in curing various diseases, so the aim of this work was to conduct a study on the ethnobotanical survey of medicinal plants with students from the agronomy course at the Federal Institute of Pará Campus Castanhal. The methodology used to carry out the study was an interview, guided by a semi-structured questionnaire. After the information collected, the systematization of the data was carried out, followed by using medicinal plants of mixed, diverse and common use as classification criteria. The results obtained were that the interviewees have considerable knowledge about medicinal plants, mentioning 48 species of plants used for the treatment of various diseases, with plants standing out for diseases with symptoms of cough, flu, inflammation and diarrhea, with different forms of preparation, among the most cited were decoction, tea, bath and juice. Despite the diverse knowledge about the use of species for medicinal purposes, this knowledge over time is lost and needs to be recovered through ethnobotanical study.
