What are the risks of taking St. John's wort?

ANSWER

Given the lack of evidence about its safety, St. John's wort is not recommended for children or for women who are pregnant or breastfeeding.

You should not take St. John's wort if you're using antidepressants, birth control pills, blood thinners, medicines for HIV, cancer drugs, cyclosporine, or digoxin.

St. John's wort has ingredients that can affect many drugs. Talk with your doctor or pharmacist if you're on any medication and decide to use St. John's wort.
