Neurodermatitis, also known as chronic simple lichen, is a common chronic inflammatory disease characterized by paroxysmal severe itching and lichenoid skin changes. Its causes may be related to neuropsychiatric factors, gastrointestinal dysfunction, endocrine disorders, local skin irritation, diet, and other factors. In Chinese medicine, mutton is considered a warm and hot product. It has the effects of nourishing the kidney and strengthening yang, benefiting qi and blood, and dispelling wind and cold. For this reason, it is also considered a "triggering food." Therefore, in clinical practice, we recommend that patients with neurodermatitis should be cautious in consuming mutton, dog meat, and other warm and dry products.
