This study aimed to realize an integrative literature review on the prevalence of the use of medicinal plants by women during pregnancy. Between November 2019 and September 2020, a survey was performed in the Scielo database and in CAPES journals with the descriptors “medicinal plant during pregnancy”, “ethnobotany and pregnant women” and their correspondents in Portuguese: “planta medicinal durante a gravidez”; “etnobotanica e gestantes”. Among the articles published in the period from 2001 to 2020, 50 studies were appropriated in the inclusion and exclusion criteria being selected for this review. All studies (100%) were conducted through interviews. One of these studies is of a multinational character. The medicinal plants most commonly used by pregnant women are Lippia alba (lemongrass -79.5%), Peumus boldus Molina (boldo -41%), Pimpinella anisum (fennel -28%) and Matricaria recutita (chamomile -28%).
