What is the cause of eczema?

Eczema is an inflammatory reaction of skin caused by many internal and external factors, accompanied by severe itching. There are three stages: acute, subacute and chronic. There is a tendency of exudation in acute stage and infiltration and hypertrophy in chronic stage. Some patients directly show chronic eczema. Skin lesions are polymorphic, symmetrical, itchy and prone to recurrent attacks.

The etiology of eczema is complex, which is often the result of the interaction between internal and external factors. Internal factors such as chronic digestive system diseases, mental stress, insomnia, excessive fatigue, emotional changes, endocrine disorders, infections, metabolic disorders, etc. And external factors such as living environment, climate change and food. Will affect the occurrence of eczema. External stimuli such as sunshine, cold, dryness, high temperature, scalding of hot water and various animal skins, plants, cosmetics, soap and artificial fibers can be induced. It is a delayed allergic reaction caused by complex internal and external factors.

According to the theory of Chinese medicine, acute patients are mainly damp-heat; Subacute patients are mostly related to spleen deficiency and dampness resistance; Chronic patients suffer from long-term blood injury due to illness, and blood deficiency leads to wind dryness and skin dystrophy; Or due to abnormal operation of qi and blood and accumulation of damp-heat. Recurrent intractable eczema, after correct "dialectical analysis", is treated both internally and externally, and the curative effect is far better than that of simple western medicine treatment.
