People often refer to psoriasis as “psoriasis”, but in fact psoriasis is not the same as psoriasis. According to Chinese medicine, psoriasis is a skin disease that looks like the skin of a cow’s collar, thick and hard, and is usually found on the neck. The Chinese medicine psoriasis is also known as “regal sores”, “urchin”, equivalent to the Western medicine neurodermatitis. Psoriasis is characterized by flaky red patches, layers of scales, and flaking like loose skin, so Chinese medicine calls it “loose skin ringworm”, and it also has names such as dry ringworm and snake lice. Western medicine believes that psoriasis (equivalent to neurodermatitis in Western medicine) is a neurological dysfunctional skin disease, caused by mental tension, eating spicy seafood and other hair products, indigestion and endocrine reasons; psoriasis onset is related to genetics, viral and cellular infections, mental, diet, trauma, metabolism and other factors. Since the etiology and clinical manifestations of the two are different, the treatment plan and prognosis are also different. Therefore, although both Chinese medicine and Western medicine have the term “psoriasis”, they are different in name and should not be confused. Psoriasis in Chinese medicine is equivalent to neurodermatitis in Western medicine; psoriasis in Western medicine is also called psoriasis, which is equivalent to dry psoriasis and snake lice in Chinese medicine. The two should be distinguished.
