Professor Li Yingang's Experience in Treating Alcohol-induced Osteonecrosis of the Femoral Head with Modified Yanghe Decoction

This paper introduces Professor Li Yingang’s experience in treating alcohol-induced osteonecrosis of the femoral head with modified Yanghe Decoction. Professor Li Yingang believes that the pathogenesis of alcohol-induced osteonecrosis of the femoral head is mainly for phlegm, blood stasis, and kidney deficiency. Among these three reasons, phlegm and blood stasis are more important. Modified Yanghe Decoction is based on Yanghe Decoction. It adds drugs such as leech, rhizoma drynariae and radix dipsaci, which could nourish Yin, tonify blood and reduce phlegm. There is abundant evidence that the clinical curative effect of Modified Yanghe Decoction is distinct.
