Today, the roots and underground stems of black cohosh are turned into herbal supplements — in the form of capsules, powders and teas — and marketed as a way to reduce hot flashes. Symptoms can range from mild to severe and include:.
But can black cohosh actually help get rid of hot flashes? Lin explains. One study found no significant difference between participants who took black cohosh and those who took a placebo.
Lin advises. People who are pregnant or breastfeeding also should not use black cohosh due to its impact on the hormones.

The use of herbs is a time-honored approach to strengthening the body and treating disease. However, herbs contain active substances that can trigger side effects and interact with other herbs, supplements, or medications.
For these reasons, you should take herbs only under the supervision of a health care provider. Some people who take high doses of black cohosh report side effects, including abdominal pain, shortness of breath, diarrhea, dizziness, headaches, joint pains, nausea, slow heart rate, tremors, visual dimness, vomiting, and weight gain.

It is not clear whether black cohosh stimulates the growth of breast cancer cells or inhibits their growth. Research has been limited and has produced mixed results.
Women with a history of breast cancer, and those at a high risk for developing breast cancer for example, a strong family history like a mother or sister with breast cancer , should not take black cohosh without talking to a provider. A few cases of liver toxicity have been reported, but a direct association with the ingestion of black cohosh has not been demonstrated.
However, you should not use black cohosh if you have liver damage or drink alcohol in excessive quantities.

It is also possible that taking black cohosh could alter the effects of drugs that are metabolized by the liver. Speak with your physician and see the Precautions section. Taking black cohosh can interact with other medicines, vitamins, and certain foods. Talk to your health care provider about possible interactions.
