Seafood was not allergic before. Now eating allergies means that your health has dropped. Some small molecules of protein in seafood are directly absorbed by human body, which causes immune response. General anti-allergic drugs are not suitable for this situation. So the best way is not to eat it, not to find any medicine to treat it. (Avoid scratching the affected part strongly, scalding with hot water and topical irritant drugs)

Traditional Chinese medicine believes that allergic patients are prone to allergic reactions due to deficiency of spleen and stomach and imbalance of internal organs.

Traditional Chinese medicine is to treat symptoms (wind, cold, dampness and heat)

From the viewpoint of traditional Chinese medicine, it is mainly caused by the dysfunction of lung, spleen and kidney.
