Observation of the clinical efficacy of traditional Chinese medicine detoxifying wash in treating tinea versicolor with gastrointestinal dampness-heat syndrome

Objective: To observe the clinical efficacy and safety of traditional Chinese medicine (TCM) detoxifying wash in the treatment of tinea versicolor with gastrointestinal dampness-heat syndrome. Methods: Ninety-three patients with tinea versicolor were randomly divided into observation group (48 cases) and control group (45 cases). This study was a single-blind, randomized controlled trial. The observation group was treated with external application of detoxifying wash, whereas the control group was treated with 1% bifonazole solution. Both groups received treatment for 20 days, with 10 days as one course. The clinical efficacy and adverse reactions were recorded after treatment. Results: After treatment, the observation group showed significant improvement in clinical indicators, including erythema, scales, itching, and skin greasiness. After 10 days of treatment, there was no significant difference in clinical efficacy between the two groups. After 20 days, the cure rate, effective rate, and fungal clearance rate in the observation group were higher than those of the control group, indicating superior clinical efficacy. No significant adverse reactions were observed in either group during treatment. Conclusion: Detoxifying wash is safe and effective in treating tinea versicolor with gastrointestinal dampness-heat syndrome.
