Widely used by Chinese doctors who are known to hail Tienchi Ginseng as the "Miracle Root for Preservation of Health," and because of its isotonic properties, botanists have classified it as an adaptogen.

Flavonoids, or bioflavonoids, play a major role in nutrition. While most ginsengs are deemed to be either yin or yang in action, Tienchi is considered to be neutral.
