Herbs to avoid during pregnancy

Although herbs are natural and very effective at treating certain ailments, not all herbs are safe to take during pregnancy. The FDA advises pregnant women not to take any herbal products without talking to their health-care provider first. Women are also urged to consult a trained and experienced herbalist/naturopathic doctor if they want to take herbs during their pregnancy.

Some herbal products may contain agents that are dangerous in pregnancy. Herbs may contain substances that can cause miscarriage, premature birth, uterine contractions, or injury to the fetus.
