Buyang Huanwu decoction has been shown to slow the progression of IDD by blocking the death receptor pathway and inhibiting the overexpression of the Fas/FasL gene, thereby promoting the regeneration of vascular buds and increasing the proteoglycan content in the CEP (Lv and Wu, 2011; Lv and Wu, 2012). This evidence concerns the gene FASLG and intervertebral disk degenerative disorder.
