Eczema should not be treated with vinegar and salt. The causes of eczema include genetics or external irritation. Vinegar and salt treatment does not treat the cause of the disease, and these irritating items applied to the skin may temporarily stop the itching, but will make the skin condition worse and is not conducive to recovery. Patients should follow their doctor’s instructions for regular treatment. Eczema treatment is divided into systemic medication and topical medication. Systemic medication: anti-inflammatory and anti-itch. Oral antihistamines, sedatives and tranquilizers are available, but glucocorticoids are generally not recommended; intravenous injections of calcium, vitamin C and sodium sulfate are available in the acute phase; antibiotics are added for secondary infections. Topical drug treatment: follow the principles of topical drug use. In the acute stage, glucocorticoid cream can be used if there is no exudation or not much exudation, and cold wet compress of boric acid solution can be used if exudation is reduced, and glucocorticoid cream can be used alternately with oil; in the subacute stage, glucocorticoid emulsion and paste can be used; in order to prevent and control secondary infection, antibiotics can be added; in the chronic stage, ointment, hard cream and coating agent can be used; in stubborn limited skin lesions, glucocorticoid can be used as intra-dermal injection. Injections of glucocorticosteroids can be used for intra-lesion injections for stubborn and limited lesions (for specific medications, please refer to the doctor’s instructions). During the treatment period, avoid all kinds of suspected causative factors, spicy food and alcohol, and excessive washing and scalding should be avoided.
