At present, traditional Chinese medicine cannot completely cure psoriasis. Traditional Chinese medicine believes that psoriasis is the result of the joint action of internal and external factors, and according to the diagnosis and treatment of psoriasis, psoriasis is usually divided into blood-heat, blood-stasis, blood-dryness, heat-poison incandescence, damp-heat accumulation and wind-damp paralysis. TCM practitioners can also choose to treat psoriasis with topical Chinese medicine preparations, including Chinese herbal ointments and Chinese herbal oils, such as Pulian Ointment and Compound Qing Dai Ointment. Chinese medicine also has external treatment methods, including rubbing therapy, Chinese medicine sealing therapy and Chinese medicine fumigation therapy, etc. Chinese medicine can be used as an auxiliary treatment for psoriasis.
