Mechanism of Traditional Chinese Medicine in the Prevention and Treatment of Psoriasis： A Review / 中国实验方剂学杂志

ABSTRACT

Psoriasis is a common clinical chronic inflammatory skin disease with a complex and diverse etiology and unrevealed pathogenesis. In traditional Chinese medicine （TCM）， psoriasis is caused by internal and external factors. To be specific， external factors such as external wind， cold， dampness， heat， insects， and other pathogenic factors can result in Qi obstruction， blood stasis， and loss of nourishment in the skin， and internal and external factors such as wind， dampness， and toxic qi attacking the exterior， heat and dryness in the blood aspect， difficulty in flourishing due to blood dryness， and blood deficiency in the body， combined with external contraction of wind and dryness trigger the disease. Modern doctors have conducted research from the blood aspect， including blood heat， blood deficiency， blood stasis， and blood dryness. Modern medicine believes that it is related to genetics， immunity， infection， and other factors， and the research on its mechanism focuses on genetic susceptibility， immune system disorder， bacterial infection， and other aspects. At present， various clinical therapies are available， mainly including systematic treatment and local external application of drugs. While treating psoriasis， TCM mainly employs oral administration or external application of Chinese medicine and traditional therapies to regulate the immune system and gene targets and resist oxidation， with high safety and few adverse reactions. At present， although the research on the mechanism of TCM in the treatment of psoriasis has been gradually deepened， there are few detailed summaries on the mechanism of TCM in the prevention and treatment of psoriasis. Based on the research on TCM and western medicine in the treatment of psoriasis， this paper reviewed the mechanism of TCM in the prevention and treatment of psoriasis and proposed a comprehensive clinical and experimental research profile， aiming to provide references for further exploring the pathogenesis， treatment， and corresponding mechanism of psoriasis.
