How Liu Jun Zi Tang works

Tonifying a damp stomach without draining it just makes more damp. So this formula tonifies with four herbs and dries with two. Tangerine peel moves the qi so the tonic does not sit; pinellia turns the phlegm and stops the queasiness. The result is a tonic that a nauseous person can keep down.
