In modern dermatology, psoriasis belongs to the category of erythematous scales, which as the name implies is a red papule or plaque covered with multiple layers of silvery white scales. There are several types of psoriasis, which are classified into four categories according to the current conventional modern dermatological classification: the common type, the arthritic type, the pustular type, and the erythrodermic type, and the manifestation of the lesion pattern is different for different types or for the same type at different stages. The diagnosis of psoriasis needs to be differentiated from other erythematous scaling diseases such as pityriasis rosea and parapsoriasis. If erythematous scales appear on the body, it is recommended that patients go to a professional doctor to confirm this, rather than judging it on their own, so as not to make a wrong judgment and delay treatment. The diagnosis of this disease in professional doctors is generally not easy to make mistakes, but the treatment is a challenge. More than 90% of the patients with psoriasis clinically are of the common type. In the treatment system of the wide sweat method, the common type psoriasis is divided into acute punctate pancytopenia, large plaque type, large plaque type, small plaque type, etc. Psoriasis patients should be mentally stable It can be clearly said that psoriasis is a psychosomatic disease. Psychosomatic disease refers to a type of physical disease in which psycho-social factors play a leading role in the whole process of disease occurrence, development, treatment, regression and prevention. In today’s society, psychosomatic diseases account for an increasing proportion of the overall diseases, and most chronic diseases belong to psychosomatic diseases. It is the result of the mutual influence and vicious circle between the body and the mind, or the manifestation of the psychological problems projected onto the body. The vicious circle of body and mind is the state of disease, or is trapped in a disease circle, and when a breakthrough point is found, transformation, body and mind to achieve a virtuous circle state, treatment will be more and more smooth, close to health. This is proven by a large number of facts in the clinic, some patients do not go through medication, have not seen a doctor, but know how to use some methods to put the mind in a good state, relax, or use biofeedback therapy, abdominal breathing therapy, etc., can slowly achieve a cure. This is to treat entirely from a psychological point of view, and it is also effective for some people; of course, there are also some patients with acute onset of psoriasis that are not particularly related to psychology, and they can also achieve good results by treating them with drugs alone. In most cases, the occurrence and development of psoriasis are closely related to the patient’s personality, emotions, tension, worries and other psychological factors and social environment. These factors are important factors in the occurrence and aggravation of psoriasis, so we need to pay attention to both physical and psychological aspects. Let’s say that some patients are always in a hurry during the treatment process, always asking, “When will it be ready?” In this case, the anxious psychology will directly affect the effect of the treatment (it is useless to be anxious when the work is done naturally). Some patients are already stable, but when something unexpected happens at home, their condition will rapidly worsen, which also suggests that we should pay attention to the stability and calmness of mind.
