Fo ti is a perennial flowering vine that reaches heights of 3–6 ft (0.97–1.8 m). It is native to southwestern China, Japan and Taiwan, but can be cultivated in many regions, including parts of North America. The root of the plant is the part most frequently used for medicinal purposes, although Chinese herbalists occasionally use the stems for different applications. The root has a sweet and slightly bitter taste. Chinese herbalists claim it has slightly warming effects in the body, and works by increasing levels of blood and vital essence.
