What is the primary use of black cohosh?

The primary use of black cohosh is for the relief of menopausal discomfort. This herbal supplement is particularly noted for its effectiveness in managing symptoms such as hot flashes, night sweats, and mood changes that many women experience during menopause. Black cohosh is believed to have phytoestrogenic properties, which may help to mimic estrogen in the body and relieve these hormone-related symptoms.

While there are other options listed, they do not accurately reflect the most recognized and researched application of black cohosh in clinical practice. It is especially important to note that its role in managing ailments such as allergies, hair loss, or weight management is not well-supported by scientific evidence, making its primary indication clear when considering its use in the context of women's health during the menopausal transition.
