Asteraceae Family Species used as Medicinal Plants in the Treatment of Respiratory Diseases in the State of Amapá, Amazon – Brazil: A Systematic Review

Abstract

Purpose: To conduct a survey of species of the Asteraceae family used to treat respiratory diseases in the state of Amapá.   Theoretical framework: The use of plants is part of popular Brazilian phytotherapy. Brazilian authorities have been regulating public policies focused on medicinal plants. Ethnobotanical and ethnofarmacological studies point to traditional knowledge about Asteraceae plants in the treatment of respiratory problems in the state of Amapá.   Method/design/approach: The review method was used, and scientific databases such as articles, theses, dissertations, and monographs were used as sources. Portuguese keywords such as "Medicinal Plants," "Respiratory System," "Ethnobotany," "Ethnofarmacology," and "State of Amapá" were used, as well as their English equivalents. Studies conducted in the Amapá territory from 2001 to 2021 were selected.   Results and conclusion: Eight species of Asteraceae indicated for respiratory pathologies were found, three of which are native to Brazil. There is a predominant use of herbaceous plants, leaves, and teas, with influenza being the most common illness treated. A. triplinervis (japana) stood out, as it was cited in five studies and is indicated for several diseases. Japana has relevant chemical and pharmacological studies that validate its ethnofarmacological use.   Research implications: The study is relevant for the valorization of traditional knowledge regarding the traditional knowledge and biodiversity of the Brazilian medicinal flora.   Originality/value: This research provides relevant information for the scientific community, as it provides data on popularly used medicinal plants that can serve as a basis for future chemical and pharmacological studies with the species found.
