Just as with prescription drugs, natural health products can present substantial risks and prompt the same areas of concern.

With the use of natural health products on the rise, physicians require quality evidence with which to make evidence-based decisions and provide answers to their patients. Herbal Medicines in Pregnancy and Lactation focuses entirely on the therapeutics, safety and risk information of herbs and supplements used during pregnancy and lactation for obstetricians, maternal-fetal medicine specialists, and primary care physicians.
