@jellies- Has your mom tried any natural estrogen? There are quite a few plants that contain phytoestrogen. It acts like weak estrogen in the body. The phytoestrogen substances actually bond to estrogen receptors in the body. This is how they react the same, only in a weaker form.
Some of the foods containing natural estrogens include beans, pumpkin, carrots, cherries, yams, pomegranates, alfalfa, and dates. There are also herbs which have an estrogenic effect. Some of these are Sarsparilla, Sage, Black Cohosh, Red Clover, and Dong Qui.
Of course, anyone would want to be sure and consult their doctor before changing the way they take prescriptions. Herbs can interact with medications, too. If you have a natural food store around your town, it’s worth looking into.
