This integrative literature review aims to analyze researches that approach the insertion of using MP in PHC. PICO strategy was used as a guideline in search of evidence, reuniting 18 articles published between January 2015 and August 2020, in the Virtual Health Library and PubMed databases. The variables of analysis were knowledge of PHC healthcare professionals about MP and associated policies, MP use by its users, highlighting their profile, the reasons that lead to the use and lack of security in MP use. The results show insufficient knowledge of healthcare professionals about Integrative and Complementary Practices policies and the medicinal uses of plants. The main users are women, elderly, with low income and education, either in Brazil or other countries. Regarding safety in MP use, frequently there is no correct identification of species, its origin, its preparation and the appropriate dose for each case. Finally, failure to approach these contents during training of healthcare professionals generates less knowledge, less research and more prejudice due to lack of information, impairing incentive and dissemination to the community.677-686engMedicinal herbsMedicinal plantsPrimary health careArtigo10.1590/1413-81232022272.463120202-s2.0-85124297509
