What is the cause of eczema?

Eczema is a skin inflammatory reaction with severe itching caused by a variety of internal and external factors. It is divided into three stages: acute, subacute and chronic. In the acute stage, it tends to ooze, while in the chronic stage, it becomes infiltrative and hypertrophic. Some patients directly present with chronic eczema. The skin lesions are characterized by polymorphism, symmetry, itching, and prone to recurrence.

The causes of eczema are complex and often result from the interaction of internal and external factors. Internal factors such as chronic digestive system diseases, mental stress, insomnia, excessive fatigue, mood changes, endocrine disorders, infections, metabolic disorders, etc. External factors such as living environment, climate change, food, etc. can affect the occurrence of eczema. External stimuli such as sunlight, cold, dryness, heat, hot water scalding, and various animal furs, plants, cosmetics, soaps, artificial fibers, etc. can all induce it. It is a delayed allergic reaction caused by complex internal and external factors.

Traditional Chinese medicine theory believes that acute cases are dominated by dampness and heat; sub-acute cases are mostly related to spleen deficiency and poor luck and lingering dampness; chronic cases are due to long-term illness and blood damage, blood deficiency causes wind and dryness, and the skin loses It is caused by nourishment; or it is caused by abnormal movement of qi and blood and obstruction of dampness and heat. Recurrent and stubborn eczema, with correct "syndrome differentiation analysis" and internal and external treatment, is far more effective than simple Western medicine treatment.
