To Evaluate the Mechanism of Jing Si Herbal Tea Liquid Packets and Traditional Western Medicine for Psoriasis

Study Purpose

Psoriasis is a chronic cutaneous inflammatory disease due to immune dysregulation. It caused skin lesions with thickening plaques and heavy silver scales over the patient's body surface area, including nail deformity, often accompanied by severe itching and pain. Psoriasis is not a contagious or infectious skin disorder, but patients' quality of life is often severely affected by skin symptoms. The annual prevalence of psoriasis in Taiwan is about 0.235%, and about one in 500 people may get psoriasis. Psoriasis has not just skin problems, but it often combines with other comorbidities such as psoriatic arthritis, metabolic syndrome such as diabetes, hypertension, hyperlipidemia and obesity, cardiovascular diseases such as stroke or ischemic heart disease, liver and kidney diseases, inflammatory bowel disease, iritis, and mental illness related to emotional stress and depression. Therefore, patients with psoriasis should regularly receive appropriate therapies to prevent complications and comorbidities. The current standard treatments for psoriasis include traditional topical and systemic treatments, phototherapy, and biologics. Traditional Chinese herbal medicine is also an alternative treatment for psoriasis due to considerable benefits and lower toxicity. Chinese medicine still plays a vital role in the treatment of psoriasis in Taiwanese societies. This experiment will further explore the anti-inflammatory effect of Jing-Si-Herbal-Tea combined with traditional western medicine for three months to reduce inflammatory mediators in the skin and blood and improve the disease severity and quality of life for psoriatic patients. key words:Psoriasis, Psoriatic arthritis, Comorbidities, Treatment, Jing-Si-Herbal-Tea, Chinese medicine
