To report a systematic review to evaluate whether topical herbal medicine delays the progress of renal disease and improves its complications in people with chronic kidney disease.


Besides dialysis or renal transplantation, patients with chronic kidney disease, especially those with insufficient renal function, are in a great need of effective conservative treatment methods. Topical application of herbal medicine, a common treatment modality in China, has been found in some clinical studies to benefit the patients with chronic kidney disease.


The English databases including CENTRAL (February 2010), Medline (1950 to February 2010), EMBASE (1980 to February 2010), and AMED (1985 to January 2010), and several Chinese databases covering the period of 1949 to February 2010 were searched for randomized controlled trials that compared external use of herbal medicine with no treatment, placebo, or conventional treatment for chronic kidney disease and its complications.


We undertook a systematic review and meta-analysis following Cochrane processes.


Twenty-three trials with a total of 1057 patients were included. Their results suggest that herbal paste and bathing or fuming treatment might have a beneficial effect in terms of delaying the progress of renal disease, improving kidney function, and ameliorating some kidney complications in patients with chronic kidney disease. However, the low quality and poor reporting practices of the studies covered led to no definitive conclusion.


Further larger and more rigorously designed clinical trials with proper outcome measures are needed to confirm the findings.
