Black Cohosh has been known as the herb for womanly symptoms and has been used by Native Americans for more than two hundred years to help relieve menstrual cramps and symptoms of menopause. These days it is still used for menopausal symptoms such as hot flashes/flushes, irritability, mood swings and sleep disturbances. It may also help with the following symptoms: PMS, menstrual irregularities, uterine spasms. This tincture has been made with 80 proof vodka. Dosages - Tinctures are meant to be used as medicine in small amounts. Add 10-20 drops to your tea, juice, water or directly into your mouth (under your tongue) when needed. I use the folk method for making all my tinctures, which uses no measurements except sizing things up with your eyes. So I put the plant material in a jar and then fill with alcohol.
