Menopause is the stage in a woman’s life when the levels of the female hormones, estrogen and progesterone, occur. This gives rise to unpleasant symptoms such as hot flashes, night sweats and insomnia. Estrogen deficiency also contributes to osteoporosis and heart disease. Hormone replacement therapy (HRT) is designed to compensate for hormonal changes in the body, but it is associated with unwanted side effects. Black cohosh is a natural herbal remedy that does not have an estrogenic effect but still relieves hot flashes and other estrogen deficit effects without having the unwanted side effects of HRT drugs.
