[Introduction]

Urticaria is a commonly encountered allergic derma-tosis due to eating fish, shrimps and crabs; or due to stin-ging of flies and injection of animal serum; or due to con-tact with pollen, nettle and certain chemicals; or due to stimulation of cold or hot air. The clinical manifestations are different-sized red or pale urticaria and abnormal pru-ritus with sudden onset and sudden disappearance. Acute case may heal in several days, while chronic case may lin-ger for months and years. Urticaria is usually caused by retention of exogenous pathogenic wind-cold or wind-heat in the skin; or by excessive intake of greasy food leading to retention of endogenous damp-heat in the skin.
