Traditional Chinese medicine is one of the most frequently chosen alternative therapies in China and Taiwan, and psoriasis has been treated for centuries with topical and oral herbal preparations. Topical indigo naturalis ointment has been reported to exhibit potential anti-psoriatic efficacy. The study objective is to investigate pharmacological effect and explore targeting mechanisms of Traditional Chinese Medicine (TCM) Indigo Naturalis topical ointment as a single treatment agent in Chinese subjects with mild to moderate plaque-type Psoriasis.\n\nThis was a single site, randomized, double-blinded, placebo controlled study of topical indigo naturalis vs. vehicle alone (placebo) to treat mild to moderate plaque-type psoriasis during an 8-week period. Pharmacological effect will be evaluated by biomarker evaluation and clinical evaluation. The trial was conducted at the China Medical University Hospital (CMUH), Taichung, Taiwan. All patients provided written informed consent before inclusion in the study. The study protocol was approved by the institutional review board (IRB) of CMUH.', 'detailedDescription': 'Estimated enrollment:\n\nTotal of 24 subjects:\n\nmild to moderate psoriasis patients will be randomized into treatment group (n=16) placebo group (n=8)\n\nStudy evaluation:\n\nA baseline and end of the study evaluation on the patients will be performed, including physical examination, hemogram and blood biochemical analysis (including glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, and creatinine measurement). The baseline and end of the study of total body surface area involvement and Psoriasis Area Severity Index (PASI), PGA, OTPSS scores will be also calculated.'}, 'eligibilityModule': {'sex': 'ALL',
