Neurodermatitis, also known as chronic simple moss, is a common chronic cutaneous neurological dermatosis characterized by mossy skin and intense pruritus. The etiology of this disease is not clear, but is generally thought to be related to dysfunction of cortical excitation and inhibition. It may be related to many internal and external factors such as neuropsychiatric factors (e.g., impatience, overthinking, stress, depression, fatigue, poor sleep, etc.), gastrointestinal dysfunction, endocrine disorders, diet (e.g., alcohol, spicy food, fish and shrimp, etc.), local stimuli (e.g., hard collars, woolen fabrics, chemical substances, infected lesions, sweat impregnation). Scratching and chronic friction may be the main causative or aggravating factors, and the vicious cycle of “itching – scratching – more itching” is formed during the course of the disease. Neurodermatitis is called “psoriasis” and “regenerative sores” in Chinese medicine, and because it is stubborn and difficult to treat, it is also known as “dermatophytosis”. This disease has been recorded in the literature of Chinese medicine for a long time. In Sui’s “Treatise on the Origin of Diseases”, it is written that “the sores on the collar are like ringworm, and they are itchy and painful on the neck, and they are sharp when the collar is brushed against them. The cloud is made by wiping the collar, so it is called collar sores. That is, pointed out that psoriasis can be aggravated by local rubbing.
