Initial Yang syndrome: After a diaphoretic is adopted, profuse perspiration will exhaust the Stomach Body Fluid. Consequently the patient feels restless, unable to fall asleep, and thirsty. Drinking a little water will harmonize the Stomach function and therefore bring about a recovery. When a floating pulse, dysuria, light fever and great thirst are observed, Wuling Powder can be prescribed as a remedy.

Wuling Powder

(Wuling San):

Polyporus Umbellatus                                18 zhu

Rhizoma Aismatis                                       1 liang 6 zhu

Rhizoma Atractylodis Macrocephalae         18 zhu

Poria                                                            18 zhu

Ramulus Cinnamomi                                   0.5 liang

Pound the above drugs into powder. Wash down the powder with rice soup. Each dose one fangcunbi. Three doses a day. Drink plenty of hot water. The syndrome is gone after perspiration.
