Ringworm is a generic term with many classifications, the common ones being tinea corporis and psoriasis. Different types of ringworm are treated differently. Before treatment, a smear test for fungus is performed, and if the stain results suggest a positive result, antifungal treatment is required. If it is negative, other diseases are ruled out and treated symptomatically. Tinea corporis is common in summer and fall and is often caused by fungal infections. Topical antifungal creams, such as miconazole and ketoconazole, are generally recommended for small areas of tinea corporis; additional antifungal medications, such as terbinafine or itraconazole, are recommended for large areas of tinea corporis and generally have a good prognosis. Psoriasis, commonly known as psoriasis, is a chronic inflammatory skin disease that may be related to genetic, autoimmune, and environmental factors. Mild patients take oral Chinese medicine anti-silver granules as prescribed by the doctor, while topical application of carbotriol or carbotriol betamethasone ointment is recommended. Moderate and severe psoriasis need to follow the doctor’s prescription to take oral medications such as Avi A capsules and methotrexate tablets. Patients are advised to pay attention to personal hygiene, keep the skin clean and dry, wear loose clothing as far as possible, avoid spicy and stimulating food during medication, and quit smoking and drinking.
