He Xi Feng (Crane's Knee Wind) is caused by the accumulation of Wind, Dampness, and Heat pathogens in the knee joint. When Heat is predominant, swelling occurs; severe swelling leads to muscle atrophy and wasting, making the knee resemble a crane's knee. Severe pain is often due to Wind pathogen, for which the following formula or Du Huo Ji Sheng Tang (Saposhnikovia and Dangshen Decoction) is suitable.

Decoct with 4 liang of fresh ginger and 2 bowls of wine, leave exposed overnight, then decoct again. Take warm, stopping when sweating occurs. For pain in the upper body, add Qianghuo (Notopterygii Rhizoma et Radix); for pain in the lower body, add Niuxi (Achyranthis Bidentatae Radix) and Yiren (Coicis Semen).
