What the Science Says
Study results are mixed on whether black cohosh effectively relieves menopausal symptoms.
Studies to date have been less than 6 months long, so long-term safety data are not currently available.
NCCAM is funding studies to determine whether black cohosh reduces the frequency and intensity of hot flashes and other menopausal symptoms.
There are not enough reliable data to determine whether black cohosh is effective for rheumatism or other uses.
