In recent years, FDA-approved drugs like sildenafil among others has been approved to treat this disorder however the drug is not without its own side effects. In a bid to develop alternative therapeutic option, scientists have now turned to traditional medicine in search of a treatment regimen. Africa is blessed with numerous medicinal plants used in the treatment and management of several diseases including erectile dysfunction. Due to limited access to modern medicine and high-quality medical facilities, a significant number of individuals in Africa continue to depend on traditional medicine as a means of addressing critical health issues. Perhaps one of the grossly explored medicinal properties of plants in Africa is for erectile function. Through years of extensive research in medicinal plants, several plants indigenous to Africa have been identified to show profound ability to mitigate erectile dysfunction. While previous reports have indeed corroborated the ability of this plant to abate erectile dysfunction, there is still a dearth of information regarding the mechanistic aspect of these plants.
