Because atopic dermatitis has a long duration and is prone to recurrence, the main objectives of its treatment are to restore the normal barrier function of the skin, to find and remove triggering and or aggravating factors, and to reduce or relieve symptoms. 1. Avoid triggering and aggravating factors Try to avoid all possible stimuli. Avoid excessive washing of the skin, especially scalding and excessive use of soap; pay attention to maintaining a suitable environmental temperature to reduce the stimulation of sweat; pay attention to maintaining a clean living environment to reduce allergens such as house dust, mites, animal hair, pollen, fungi, etc.; pay attention to observing the reaction to the food you eat to avoid Avoid consuming allergenic food. Correcting dry skin, protecting skin barrier function and stopping itching are the key measures to treat atopic dermatitis. In the acute phase, bathing with warm water once or twice a day will increase humidity while also helping to reduce exudation and remove scabs and residual medication; in the chronic phase, bathing can be done once a day. Whether in the acute phase or in remission, the application of emollients and/or moisturizers is extremely necessary and should be applied topically (mostly advocated for systemic use) at least 1~2 times daily, especially immediately after bathing, to maintain the hydrated state of the skin and protect the barrier function and reduce itching symptoms. Atopic dermatitis (AD), also known as genetic atopic dermatitis, genetic atopic eczema, atopic dermatitis, etc., is an allergic skin disease with genetic predisposition, belonging to type I and IV concurrent allergic reactions, in clinical stages: infancy, childhood and adult. Clinical treatment is difficult to heal and prone to recurrence. It is similar to the “four bends of wind”, “milk ringworm” and “stubborn ringworm” mentioned in Chinese medicine. It is generally believed that AD occurs due to congenital deficiency of endowment, eating five pungent and hairy substances, and leaving heat in the fetus; or acquired dietary imbalance, resulting in weakness of the spleen and stomach, which causes dampness to arise from within, and external exposure to wind, dampness, and heat evil, which is depressed in the skin couples and causes the disease. The cause of the disease is due to internal causes, not other than dampness, heat and wind. Treatment should be to strengthen the spleen and dampness, clear heat and dispel wind to stop itching. For a long time, it is advisable to nourish Yin and remove dampness to relieve itching.
