The flame vine is native to Brazil. This beautiful vine with long orange tuber flowers has become a common accent to many gardens and has attracted pollinators including hummingbirds. However, the flame vine grows like wildfire and can become invasive rather quickly (University of Florida).
Indigenous people of Brazil used the plant to treat several conditions including skin irritations, diarrhea, coughing, respiratory infections, bronchitis, flu, and cold. Research has found several pharmaceutical properties in the plant including antioxidant, anti-inflammatory, analgesic, antinociceptive, wound healing properties, antimicrobial, reduction in cold and fever symptoms, treatment of menopause, and melanogenesis. These properties can be carefully extracted and refined to produce a number of medications (Mostafa, El-Dahshan, and Singab 2013).
