Can I take black cohosh if I am having hot flushes? How much?

Yes, depending . . . . . . On what other medicines you're taking and medical conditions you have. Please consult your physician first. But in research tests black cohosh (actaea racemosa) has been found to be safe in doses between 40-80 mg/day, for 6 months. The tablets should be standardized to contain 1 mg of 27-deoxyactein.
