What natural herbs work well for treating hot flashes?

Herbs and oils that may be effective in treating hot flashes include red clover, black cohosh, dong quai, soy and evening primrose oil, according to Healthline. There is not enough evidence to back up the herbs' effectiveness, and some may cause dangerous interactions with other drugs.

Hot flashes are sensations of intense heat that may cause sweating, a faster heartbeat and tingling in the fingers, explains Healthline. While the cause of hot flashes is unknown, hormonal changes in the body are the most likely culprit. Three in four women in the perimenopausal stage experience hot flashes, while those who have reached menopause may continue to have hot flashes for six months to five years.
