The efficacy of traditional Chinese herbal therapy in atopic eczema.

A traditional Chinese herbal therapy (Zemaphyte) for the treatment of atopic eczema (AE) is currently being assessed. This review attempts to highlight its success in patients who are recalcitrant to Western forms of treatment and the rationale behind its use. The herbal preparation is a mixture of 10 herbs with some known pharmacological agents and actions. The concept of such a complex mixture in clinical treatment is anathema to Western medicine but acceptable in traditional Chinese medicine. As this formation has been shown to be effective in two double-blind crossover trials, investigative work on components from the mixture must be established in order to find the active constituent(s) and describe their mode of action. This research will also lead to a greater understanding of the complex immunopathology of AE.
