The etiology of psoriasis is unclear and can initially be triggered by upper respiratory tract infections. It is a common chronic recurrent inflammatory skin disease of dermatology, produced by a T-cell mediated immune response. It presents as silvery-white scaling of the skin, erythema, papules, and plaques. The disease can be cured and, without attention, is prone to recurrence. It is divided into common, arthritic, erythrodermic, and pustular types. Be careful not to drink alcohol, rub or scratch. There are no curative drugs available worldwide. The efficacy of the disease varies greatly among individuals An old professor of our department said: The treatment of psoriasis is that Western medicine is not as good as Chinese medicine, fast treatment is not as good as slow treatment, and treatment is not as good as therapy. This is only for the reference of patients and friends. Therefore, I suggest that patients should not seek excessive cure prescriptions, excessive medical treatment, but bad.
