Which is a common contraindication for Actaea racemosa (Black Cohosh)?

• A. Pregnancy
• B. Regular exercise
• C. Vitamin C deficiency
• D. Diabetes

Answer: (A)

Black cohosh can have estrogen-like effects and may influence uterine tone. In pregnancy, anything that could stimulate the uterus or alter hormonal balance is approached with caution because it could affect implantation, maintenance of pregnancy, or trigger contractions. Because the safety data are limited and there is theoretical risk, pregnancy is a contraindication for Actaea racemosa. Regular exercise is safe during pregnancy, and neither vitamin C deficiency nor diabetes constitute a specific contraindication for this herb in this context.
