Some TCM dermatologists are usually more strict about psoriasis, advising patients not to eat spicy and seafood foods, and not to drink alcohol, some including beef, mutton, chicken or pig’s head and feet, offal, etc., are not recommended, as well as green vegetables with pungent smell, such as celery and parsley, and raw food of onion, ginger and garlic are not recommended. However, if the patient has had the disease for a long time, or if his disease is in a stable stage and there is no new rash for a long time, the avoidance of food may not be so strict. Usually avoid spicy food, seafood and wine, other foods are based on personal feelings, if you do not feel significantly worse after eating, it is recommended that you can eat less.
