Psoriasis is a chronic, relapsing, inflammatory disease and so far the mechanism of action of psoriasis is not clear, its not caused by a single bacteria or virus. It is also impossible to have a vaccine in this area, because its mechanism of action is different and its targets are also different, so its impossible to have a vaccine. But psoriasis does have a greater impact on patients in their lives and is a major disease. A series of advances have been made in various aspects of clinical research, including the use of biological agents, and the rate of improvement has increased significantly. Chinese traditional medicine in China plays an increasing role in the treatment of psoriasis and is increasingly valued by the state. With the joint efforts of Chinese medicine and Western medicine, there will be more and more means of treatment for psoriasis, and the treatment effect will become better and better, which can enable patients to live a more decent and better life.
