Black cohosh is one of the most popular herbs used to treat hot flash. The root of this plant is used in capsules and teas, both of which are easily available in health food stores and online.

However, this herb has some minor side effects like stomach aches and rash. Additionally, even liver failure was reported in a few individuals taking black cohosh, which is lethal. Therefore, you should talk to your doctor before taking it and inform your doctor about any pre-existing conditions.
