This type of natural hormonal replacement is best applied through the skin in a cream form. The reason is that very little progesterone is actually assimilated via the digestive tract. PMS, Peri-Menopause, and Menopause symptoms can be traced to an imbalance of progesterone to estrogen. A deficiency of progesterone develops in relation to an excess of estrogen. This imbalance results in an abnormal excess of estrogen.
Excess estrogen can also cause a lack of libido.
Besides this imbalance, which usually begins in the hypothalamus, there are zeno-estrogens in our environment that can enter into our bodies, both men and women. These estrogens can be found in herbicides, pesticides and the foods we eat. Some women may say they are on birth control pills and therefore they receive their proper supply of progesterone. Birth Control Pills contain Progestin, which is a synthetic form of progesterone. Progestin has been known to cause breast cancer.
