Traditional chinese medicine and herbal supplements for treating overactive bladder

Overactive bladder (OAB) has a high prevalence of approximately 16%–18% of the population worldwide. Currently, the understanding of and strategies for pharmacological treatment of OAB remain limited to antimuscarinics and β3 agonists. Ethnopharmacology applies knowledge from traditional medicine to treat diseases. For example, several presently used drugs, such as aspirin, digoxin, and artemisinin, have originated from plant extracts. Ancient people have historically required treatments for urinary urgency, urinary frequency, nocturia, and urgent incontinence. Traditional Chinese medicine (TCM) has been developed in China over the course of thousands of years. Some regimens and single-herb medicines of TCM have been demonstrated to manage such OAB symptoms. Herein, we summarize the evidence, obtained through current scientific methodology, which supports the use of regimens and single-herb medicine for treatment of OAB. An understanding of the pros and cons of TCM from the viewpoint of current science would improve future research and provide patients with more alternative and complementary therapies.
