Chang Gung Memorial Hospital24 enrolled

Overview

The aim of this study is to investigate the effects of topical herbal medicine in the patients with rosacea.

Rosacea is a chronic inflammatory disorder which affects the cheek, nose, chin, forehead and eyes. It is typically characterized by cutaneous signs such as flushing, erythema, telangiectasia, papules, and pustules in the face. The pathogenic mechanism of rosacea is unknown, and there is no cure for rosacea. The therapeutic approaches include oral medicine, topical medicine and surgical interventions depending on the different subtypes of rosacea. The recent study demonstrates that combination therapy may be more effectively improved the symptoms of rosacea. Dian dao san is a topical herbal compound for reducing the features as flushing, erythema, papules, and pustules for years. The investigators hypothesize that dian dao san can be more beneficial in treating the patients with rosacea and improving the quality of life.

Scale Range:The DQoL consists of 10 questions, each scored on a scale from 0 to 3: 0 = Not at all, 1 = A little,2 = A lot,3 = Very much The total score ranges from 0 to 30, where higher scores indicate a greater negative impact of the skin condition on quality of life. Interpretation of Scale Scores: Total Score 0-1: No or minimal impact; 2-5: Mild impact; 6-10: Moderate impact; 11-20: Significant impact; 21-30: Severe impact Higher DQoL scores indicate worse quality of life due to the skin condition, while lower scores suggest minimal impact. Computation of Scores:DQoL total score is calculated as the sum of the 10 item scores. Unit of Measure: "Scores on a scale" should be used as the Unit of Measure if no other units apply.
