Abstract
Objective: To identify the popular uses of P. pilosa in the Brazilian Amazon region, and to verify if there are studies that confirm its biological activity. Methods: This is a qualitative study of a bibliographic review of ethnobotanical studies conducted in the Brazilian Amazon region and pharmacological studies. The literature search was performed in scientific databases without date restrictions, in national, international journals, books and academic papers. Results: Several use claims were found, among them are liver diseases, stomach problems, diarrhea such as deworming, antimalarial, combating hair loss, healing, anti-inflammatory and analgesic. The pharmacological potential of the last three indications has been proven. Final considerations: Despite the medicinal importance of the plant species for the Amazon, pharmacological studies are still scarce, and studies that validate its use for the treatment of liver and gastric diseases, as well as their anti-inflammatory activity, are urgent. P. pilosa presents itself as a plant of great interest to the Amazonian community as well as to the scientific community.
