Little Evidence That Herbal Medicines Relieve Menopausal Symptoms

A systematic review has found little evidence that herbal remedies help relieve menopausal symptoms

18 jan 2009--Among the findings, published online in Drug and Therapeutics Bulletin:

• Black cohosh: Three controlled trials suggested a salutary effect, whereas four others did not. The herb has been linked to liver toxicity.
  
• Red clover: A meta-analysis found no benefit.
  
• Dong quai: The remedy was no better than placebo in one trial, but better than placebo in another, where it was combined with chamomile. It's contraindicated in patients taking warfarin, as it may increase the risk for bleeding.
  
• Evening primrose: The treatment was not superior to placebo in one trial. Evidence suggests that it may further increase the risk for seizures when used along with other drugs that can cause seizures.
  
• Ginseng: Two trials showed no effect.
  

(These findings are similar to those of a previous systematic review.)
