Hot flashes for most women can be stop naturally by black cohosh. Adding phytoestrogens and red clover can be more helpful because phytoestrogens are those plant components that have an estrogen-like effect. They may compete with the estrogen in our bodies and it help prevent cancer before menopause. But it is not certain that this effect persists after menopause.

Further study is needed into the effects, as safety of high doses of phytoestrogens after menopause is needed before a very high intake of these compounds can be recommended for postmenopausal women.
