Sheng Mai Yin (Ginseng, Ophiopogon & Schisandra Formula)

First recorded by the Jin-dynasty physician Zhang Yuansu, Sheng Mai Yin — “generate the pulse” — is a three-herb classic: ginseng to replenish qi, ophiopogon to moisten, and schisandra to gather and hold. It is a traditional choice after exertion, heavy sweating or long stretches of fatigue.
