    Black Cohosh is the most popular supplement for menopause in North America, but the results of human studies are mixed. It holds some benefits for controlling hot flashes and night sweats.

    Overview

    Dosage information

    If using an isopropanolic extract (usually sold under the brand name of Remifemin), 20-40mg daily is used in doses of 20mg; taking 20mg results in a once daily dosing, whereas taking 40mg is twice daily dosing of the 20mg. This dosage (20-40mg) confers 1-2mg of triterpenoid glycosides.

    If using an aqueous:ethanolic extract of black cohosh root (ie. not Remifemin) then doses range from 64-128mg daily which are usually taken in two divided doses. This contributed about the same amount of triterpenoid glycosides.

    It is not known whether or not black cohosh needs to be taken with food, although it is sometimes recommended to do so out of prudency.
