Psoriasis can eat eggs because patients with psoriasis can produce scales, and scales are proteins, and psoriasis patients lose proteins, which can be replenished by eating eggs. Patients with psoriasis should not smoke, drink alcohol, or eat spicy and stimulating diet, such as raw onion, raw garlic, strong tea and coffee. In terms of treatment, patients with psoriasis can take compound glycyrrhizin capsules and compound aminoglutethimide tablets orally. In terms of topical medications, topical glucocorticoid ointment can be used, such as hydrocortisone butyrate ointment, dinaide ointment, mometasone furoate ointment, halometasone ointment, or fluticasone propionate ointment. Topical carbotriol ointment or carbotriol rub can also be used. And patients with psoriasis can do phototherapy as well as medicated bath treatment, and phototherapy medium-wave narrow-spectrum ultraviolet radiation is good.
