Psoriasis, commonly known as “psoriasis” and “white H” in Chinese medicine, is one of the most common skin diseases in dermatology. When patients come to the doctor, besides being concerned about the efficacy and side effects of the drugs, the most common question they ask is whether psoriasis can be “eradicated”. As a doctor, it is the greatest wish to relieve the pain of patients, but unfortunately, medical development to date, most diseases can not be eradicated, psoriasis is one of them. Despite the persistent efforts of scientists, the exact cause of psoriasis remains an unsolved mystery. Current research suggests that the onset of psoriasis is related to a variety of factors such as polygenic inheritance, infection, metabolic disorders, and immune dysfunction, but the exact cause and pathogenesis have not yet been clarified. The existing treatment drugs can only control the symptoms and reduce recurrence, but cannot fundamentally cure the disease, that is to say, there is no method to “root out” psoriasis. In the clinic, we often encounter some patients who blindly believe in the so-called “root” propaganda of irregular hospitals or clinics, pursue the rapid effect of drugs and blindly seek treatment, which not only costs money and time, but also leads to aggravation of the disease or causes damage to internal organs, which is very distressing. As a doctor, it is most common to use some oral Chinese medicine or injections with unknown ingredients, which have obvious effects for a short time, but once the drug is stopped, the skin lesions recur, so the long-term use of these drugs, or the formation of dependence on drugs, after half a year or even longer, what was originally the lightest type of common psoriasis turns into a serious type, such as pustular psoriasis, erythrodermic psoriasis; Others have caused damage to liver and kidney functions due to drug abuse, and there are even patients whose use of some toxic drugs has led to the occurrence of skin cancer. Under the guidance of doctors, the rational use of drugs can well control the psoriasis condition and reduce recurrence; greatly improve the quality of life, and also do not harm the health of internal organs. At present, many countries in China, Europe and America have issued guidelines for the diagnosis and treatment of psoriasis, advocating regular and safe treatment of psoriasis; Chinese medicine has its own unique insights into the etiology and pathogenesis of psoriasis, and at present, many doctors recognize the “treatment from blood”, believing that blood heat is an important pathogenesis of psoriasis, and Chinese medicine has achieved good results in treating psoriasis with evidence-based treatment. The use of oral and topical Chinese medicine can effectively control and reduce the recurrence of psoriasis; Chinese medicine bath therapy with light therapy can promote the faster fading of psoriasis skin lesions. Therefore, do not be nervous and anxious when you have psoriasis, ask a doctor for treatment at a regular hospital, do not blindly believe in advertising; be calm and relaxed, learn to “live peacefully” with psoriasis, use safe and effective methods to control the disease, reduce recurrence, and minimize its interference with daily life and learning.
