银屑病
Alias白疕
Traditional Chinese Medicine Definition
In traditional Chinese medicine, psoriasis is known as "白疕" (Bái Pi), a common chronic and recurrent dermatological condition. As recorded in "Traditional Chinese Internal Medicine," the pathogenesis is attributed to either endogenous blood heat or blood deficiency with dryness and wind, presenting with symptoms such as red rashes and scales on the skin.
In clinical practice of traditional Chinese medicine, the core pathogenesis of psoriasis is often related to endogenous blood heat or blood deficiency with dryness and wind. The endogenous blood heat pattern is commonly characterized by fresh, red skin lesions with rapid progression and pruritus; while the blood deficiency with dryness and wind pattern manifests as a longer course with pale red, dry skin lesions and thick scales. Common precipitating factors in clinical settings include emotional disturbances, irregular diet, and overexertion. During the differential diagnosis, attention should be paid to distinguishing cold, heat, deficiency, and excess. The treatment approach for the endogenous blood heat pattern focuses on clearing heat, cooling the blood, detoxifying, and resolving rashes. For the blood deficiency with dryness and wind pattern, the primary focus is on nourishing the blood, moistening the dryness, expelling wind, and stopping itching. The overall treatment direction suggests harmonizing the nutrient and blood, expelling wind, and stopping itching to improve the quality of life of patients.
