The use of medicinal plants in order to treat tropical diseases such as malaria is of extreme importance, particularly in places where the public health system is not present as in most coastal communities of the Amazonia region. That being stated, investigating and rediscovering the popular knowledge of medicinal plants used to treat malaria and its associated diseases by the residents of the Julião community, located in RDS Tupé, Manaus-AM, becomes relevant in recording how local populations prevent and treat this disease so prevalent and dangerous in this region. In order to carry out this study, it was implemented an ethnobotanical survey through workshops organized in categories and semi-structured interviews as well as guided tours by residents of the community in their backyards and nearby forest areas. The Shannon- Wiener diversity indicators were calculated, measuring equitability and concurrence regarding its main use (CUP). From the effective collaboration of 13 community members, 62 plant species belonging to 53 types and 34 botanic families were observed,which resulted in a diversity index (H ‘) and equitability of 1.62 decits 0.9. The most significant botanical families shown in the survey were: Fabaceae (7 species), Asteraceae (4 species), Lamiaceae (4 species), Solanaceae (3 species) and Rubiaceae (3 species). It is worth to highlight that 16 species (25.8%) were mentioned for malaria treatment and associated diseases, for the first time in ethnobotanical studies conducted in Latin America. © 2015, Instituto de Biociencias.
