People often refer to psoriasis as “psoriasis”, and both Chinese medicine and Western medicine have “psoriasis”, but the two names are the same and different and should not be confused. Psoriasis in Chinese medicine is equivalent to neurodermatitis in Western medicine, and it occurs on the neck, elbows, and eyelids, and is characterized by thick and hard local skin, rough surface, and itching. Psoriasis, as it is called in Western medicine, is psoriasis, which is equivalent to “white diphtheria” in Chinese medicine, manifesting itself as flaky red patches, layers of scales, flaking like loose skin, and itchiness that varies from person to person, and often it is not obvious. The causes and mechanisms of the two are also different. In Chinese medicine, psoriasis is caused by wind-damp-heat evil blocking the skin, or by friction on the collar, and blockage of Qi and blood. In psoriasis, it is due to the loss of blood, wind and dryness, and loss of nourishment of the skin. According to Western medicine, psoriasis (equivalent to neurodermatitis in Western medicine) is a neurological dysfunctional skin disease caused by mental stress, consumption of spicy seafood and other hair products, indigestion and endocrine factors, while psoriasis is related to genetic, viral and bacterial infections, mental, dietary, traumatic and metabolic factors. Because the causes, pathogenesis and clinical manifestations of both are different, the treatment options and prognosis are also very different. In Chinese medicine, psoriasis is often treated with treatments to dispel wind and relieve itching, while in Western medicine, nerve regulation and topical medications are used, with a good prognosis. In Western medicine, psoriasis (i.e., psoriasis) is classified according to the tongue and pulse, and most of the treatments are based on clearing heat and cooling blood and nourishing blood and moistening dryness, while Western medicine is divided into four types: common, pustular, arthritic, and erythrodermic. It is easy to recur.
