The Pyrostegia genus of the Bignoniaceae family. This genus is consists of four species and indigenous to South America. The plants of this genus are being applied in traditional uses in Brazil. This review of the scientific work about Pyrostegia genus was highlighting and updating their traditional uses, phytochemical compounds, pharmacological activities, genotoxicity tests, and toxicity studies. The information was systematical with the scientific literature database, including Elsevier, Google Scholar, PubMed, Science Direct, and Scopus, and Springer. The literature survey showed various traditional uses of Pyrostegia genus, such as drugs to therapy diarrhea, coughing, vitiligo, jaundice, and respiratory system-related diseases, i.e., colds, coughs, and bronchitis. Phytochemical compounds from the Pyrostegia genus have shown the presence of flavonoids, phenolic compounds, phenylpropanoids, phenylethanoid glycosides, triterpenes, and sterols. The extract of Pyrostegia genus has a variety of pharmacology actions, i.e., antioxidant, antimicrobial, antifungal, anti-inflammatory, wound healing activities, antinociceptive, analgesic, vasorelaxant activities, antitumor, cytotoxic, hepatoprotective, antitussive, anthelmintic, hyperpigmented, treatment of sickness behavior, estrogenic, antihypertensive, and immunomodulatory. Pyrostegia genus is considerably used in traditional medicines and has various pharmacological activities. However, most species of Pyrostegia genus must be further researched concerning its chemical constituents and pharmacological activities.
