Drug interactions are complicated, so have all of your medications -- even herbals, vitamins and other OTCs -- screened by your doctor or pharmacist to review for Black Cohosh drug interactions.

Black Cohosh is a shrub-like plant found in North America. It is often used for menopausal disorders ("hot flashes"), painful menstruation, uterine spasms, and vaginitis. However, prescription drugs broken down by certain liver enzymes may accumulate in the body and lead to toxicity if used with black cohosh.

Signs of liver disease include:

• fever
• chills
• joint pain or swelling
• unusual bleeding or bruising
• skin rash
• itching
• loss of appetite
• fatigue
• nausea, vomiting
• abdominal pain
• dark urine
• pale stools
• yellowing of the skin or eyes.

If you notice these symptoms, call your doctor right away.
