Chinese herbal treatments are being promoted as a treatment for eczema. The aim of this study was to systematically review the evidence for or against this notion.
Extensive literature searches were carried out to identify all randomised clinical trials on the subject. Data were extracted from these in a predefined standardized fashion.
Only two randomized clinical trials were located. Both imply that a complex mixture of Chinese herbs is more effective than placebo in treating eczema. Yet several caveats exist, most importantly the lack of independent replication. Adverse effects have also been reported.
At present it is unclear whether Chinese herbal treatments of eczema do more good than harm.
中草药疗法正被推广用于治疗湿疹。本研究旨在系统评价支持或反对这一观点的证据。
进行广泛的文献检索以识别关于该主题的所有随机临床试验。以预先定义的标准化方式从这些试验中提取数据。
仅找到两项随机临床试验。两者均表明,中药复方在治疗湿疹方面比安慰剂更有效。然而,存在一些警告,最重要的是缺乏独立重复验证。也有不良反应的报道。
目前尚不清楚中草药治疗湿疹是利大于弊还是弊大于利。
