Johanna,
Thank you for your book suggestion. I'm looking forward to seeing what it has to say.

There's also something that I think I need to clarify about the liver. My ND (Naturopathic Doctor) has me on a therapeutic level of progesterone in order to address the estrogen dominance in my uterus (which has caused both fibroids - excessive bleeding - & pre-cancerous cells). Since she wants the FULL potency to be at work, she chose to have me use the suppositories so that my liver wouldn't have a chance to break any of the progesterone down, thus weakening the dose. The purpose is to get my hormones back into balance.

Having said that, she is also working on getting my liver to function at an optimal level through detoxification so that it can handle all of the hormones properly when I begin using the natural progesterone cream, which will be when the estrogen is no longer dominant.

I hope this explanation helps.

Cheryl
