Promotes Menstruation: Castleman agrees that Blue Cohosh can be used to promote menstruation, but he feels that the dose needed to do so can be dangerous. However, Tierra feels that a gynecological formula consisting of equal parts blue cohosh, black cohosh, angelica, cramp bark, and wild ginger can be very effective in treating delayed or stopped menstrual cycles. On the other hand, source after source on the Herbal Materia Medica site indicate that blue cohosh is aVERY effective herb in treating the absence of menstruation.
Prevention of Miscarriage: Unlike Castleman, all of the sources at Herbal Materia Medica suggest using Blue Cohosh to prevent miscarriages.
According to Herbal Materia Medica--Decoction: Put l teaspoonful of the dried root in a cup of water, bring to the boil and simmer for l0 minutes. This should be drunk three times a day.
