Psoriasis recurrence should be actively consulted, and standardized and reasonable treatment should be given under the guidance of doctors. For example, if the rash is large in scope, you can take oral Aviatica capsule, which has the function of anti-inflammation, regulating immunity and inhibiting excessive epidermal proliferation, or you can also take oral compound glycyrrhizin tablets for anti-inflammation. Oral herbs that clear heat and detoxify the toxins and cool the blood to dispel wind can also be taken, together with topical medication, such as topical application of zinc oxide ointment of boric acid and dinaide cream. The causes of psoriasis recurrence should also be corrected, for example, some patients are overworked and poorly rested, resulting in a decline in immunity, so they need to pay attention to rest and strengthen nutritional intake so that immunity can be restored as soon as possible. There are also patients whose relapse is due to upper respiratory tract infection, for which active anti-inflammatory treatment is needed, which is beneficial to psoriasis recovery.
