Evidence-Based Complementary and Alternative Medicine
Chinese data bases were screened for published studies on the effect of chinese herbal medicine on threatened miscarriage. While more than 300,000 papers were found, the trials generally did not meet the clinical research standards that would be required in the west. That said, it is not always easy or ethical to carry out placebo controlled randomised trials with pregnant women who are worried about miscarrying. Meta-analysis of some of the clinical trials indicated that Chinese medicines alone or Chinese medicines combined with Western medicines were more effective than Western medicines alone to treat threatened miscarriage in relieving the clinical signs, including vaginal bleeding, low back pain, and abdominal pains.
