Psoriasis, commonly known as “psoriasis”, is called “white H” in Chinese medicine. Through our visits and observations, many patients come to our office through regular Chinese medicine treatment for a long time without recurrence, and even some patients do not recur for life, even this can not be called a “cure”. Many patients ask about the treatment period of this disease during the consultation, but this is a question that has no answer. I suggest that the best follow-up period is half a month if the patient can get an appointment. Due to the difficulty of registration and other factors, some patients cannot come to the follow-up in time, so it is best not to stop the medication at will, but to continue taking it for a period of time according to the original prescription, but not more than a month at the latest. Psoriasis patients should avoid eating spicy and stimulating foods during the treatment process and for a period of time after the cure, eat a light diet, do not overwork, and maintain a relaxed mood to avoid aggravating the lesions or triggering the disease again. Frequent warm baths can help promote the recovery of the disease. When encountering a sudden aggravation or relapse of the disease, patients should not be impatient and panic, you can make an appointment to come to the clinic, if you can not make an appointment, you can apply for a telephone communication on the appointment.
