Psoriasis is a frequently encountered chronic inflammatory dermal disease. The duration of this disease is long, and occurs mostly in young adults. The etiology and pathogenesis of this disease is still unknown and may be related to genetic, infective, and metabolic, endocrine, nervous, mental, and immmunological disturbance. In Chinese medicine this disease is called “Bai Pei” and “Song Pi Xian”. It is mostly caused by Blood Heat, Blood Dryness or Blood Stasis. If prolonged accumulation of blood heat is attacked by pathogeneic damp toxin simultaneously, it can cause complication of heat toxin mixed with dampness. If the meridians and collaterals are obstructed by exogenous wind, dampness and heat toxin, it can lead to joint affection.
