Treats wind-damp-cold bi-syndrome (painful obstruction syndrome caused by wind, dampness, and cold pathogens), with generalized swelling and fullness, painful numbness and insensitivity, aversion to cold in diet, shivering chills, phlegm-fullness in the chest, and stuffiness below the heart. (Formula see Wind-Stroke Section)

Joint pain, inability to flex or extend, emaciated body, swelling feeling as if detached, pain feeling as if being pulled or wrenched, pathogenic factors flowing into the bone joints, shortness of breath, spontaneous sweating, dizziness, and a sensation of nausea wanting to vomit are all caused by the struggle among wind, dampness, and cold. Pain feeling as if being pulled or wrenched indicates excess cold; swelling and fullness feeling as if detached indicates excess dampness; yellow sweat exuding from the joints indicates excess wind. According to *Zhubing Yuanhou Lun* (Source Book of All Pathologies), drinking while exposed to wind, or entering water while sweating, leads to this disease. Tracing its etiology, although it involves wind, dampness, and cold, the mention of drinking alcohol classifies it under "neither internal nor external causes" (Bu Nei Wai Yin). There are also those who suffer from this without drinking alcohol; one must investigate the cause and treat according to priority and severity. If left untreated for a long time, it causes dislocation of bone joints and transforms into epilepsy, which must not be ignored.
