Hi @LisaO, It's Lisa from the Policy Team. Like @socoda and @TonyaM have said, Memorial Sloan Kettering Cancer Centre's
'About Herbs' website can be helpful as you can type in specific vitamins, herbs or botanicals that you are interested in and get information about the products as well as possible interactions with medications. Though, we always recommend talking to your doctor before taking anything new as some products can reduce the effectiveness of medications, such as hormone therapy.
I just wanted to add that our
Hormone Therapy booklet might be useful. It has information about strategies that can help reduce the side effects of hormone therapy as well as information about complementary medicines and therapies.
Warm regards,
Lisa
