Yes, Liver Cleansing is essential when you have fibroids. The liver is responsible for taking estrogen and progesterone out of the bloodstream after it's been manufactured. If the liver is clogged, it cannot do this properly, and so the hormones get attached to fats and end up creating fibroids and endo tissues.
Be sure to do a comprehensive Liver Cleansing program, not just flushes. See the Liver Notes in the FAQ for more options and do as many as you can.
Avoid the more potent estrogen foods like Soy. Soy is the #1 cause of fibroids in otherwise healthy women.
