To date there is not a lot of research published on the treatment of endometriosis with Chinese medicine that meets the standard required for us to draw firm conclusions on efficacy. One review has analysed findings from 10 small trials that used acupuncture to treat endometriosis pain, and one randomised controlled trial has examined the use of chinese medicine to prevent recurrence after surgery.

While further studies are warranted before clinical recommendations are made, this systematic review found in the trials analysed (involving 589 women) that acupuncture reduces endometriosis pain and serum CA-125 levels

A randomised and controlled trial (involving 200 women) studied the prevention of recurrence of endometriosis after surgery and showed that Chinese medicine was as effective a therapy as western pharmaceuticals in preventing recurrence but had significantly fewer side effects. Chinese medicine achieved a higher conception rate in women who had previously been infertile.

This lengthy review compares results of treatment of endometriosis with acupuncture or herbal therapies and pharmaceutical or surgical approaches. A number of therapies, including using Chinese herbs per rectum, were found to obtain relief from symptoms of endometriosis, but without the side effects caused by drugs or surgery.
The authors conclude that the active principle of such therapies has a strong foundation but that standardisation of techniques and larger RCTs are needed.
