Natural remedies for hot flashes include evening primrose oil, soy products and flax seed, according to WebMD. Black cohosh root is another recommended natural remedy.
Evening primrose oil is a botanical that is commonly used to treat hot flashes. Soy products are also recommended as a natural remedy for hot flashes. The plant estrogens that are present in soy products are considered to have weak estrogen-like effects that could help reduce these symptoms. Flax seed, also referred to as linseed, is also thought to reduce menopause symptoms, notes WebMD. Black cohosh may be useful for a limited period of six months or less for treating hot flashes.
