I know of a naturopath (as I am training to be one herself) who through her training and knowledge has cured herself and many others through lifestyle change and herbs of endometriosis.
I've heard good reports of success with this type of treatment.
This is quite a simple link from a website I've found with every cure both holistic and allopathic.
If I can find out any herbs that are good etc, will post them later.
A couple of things that spring to mind off the top of my head as good treatments as ginko as it increases the circulation and accupuncture.
