Red clover (Trifolium pratense) is a flowering plant that grows 15-40 cm high. It's eaten as a legume and used in supplements marketed for female health.

Soy (Glycine max) comes from soybeans. The beans are a legume that come from China. They can be processed into soy protein, soy milk, or soy fiber. Soy contains isoflavones which are changed in the body to phytoestrogens. Phytoestrogen molecules are similar in chemical structure to the hormone estrogen.

Red clover contains chemicals called phytoestrogens that are similar to the hormone estrogen. It grows in many areas, including Europe, central Asia, and northern Africa.

In some cases, these phytoestrogens can mimic the effects of estrogen. In other cases, these phytoestrogens can block the effects of estrogen. Soy is used for high cholesterol, high blood pressure, heart disease, diabetes, symptoms of menopause, and premenstrual syndrome (PMS). It is also used for many other conditions.

People commonly use red clover for symptoms of menopause, weak and brittle bones, breast pain, male-pattern baldness, and many other conditions.
