How to make it
2–3 thin slices steeped in hot water, re-steep through the day; or double-steam 6 g with chicken. Small daily amounts through winter beat occasional large doses.
Why it works
Keep away from strong tea/coffee (tannins bind the active ginsenosides).
Classical source
Ginseng is the most revered herb in the Shennong Bencao Jing — "lightens the body and extends the years".
