Background

Peony (Paeonia lactiflora) is an herb. The roots are commonly used in Traditional Chinese Medicine (TCM) for many purposes.

Peony might block chemicals that can cause pain and swelling. It might also prevent blood clotting, kill cancer cells, and act as an antioxidant. Peony is sometimes called red peony and white peony. This refers to the color of the processed root, not the color of the flowers.

People use peony for menstrual cramps, aging skin, cough, epilepsy, psoriasis, and many other conditions, but there is no good scientific evidence to support these uses.
When taken by mouth: Peony is possibly safe when used for up to 6 months. It can cause stomach upset in some people. There isn't enough reliable information to know if peony is safe to use long-term.

When applied to the skin: There isn't enough reliable information to know if peony is safe. It can cause rash in some people.

Special Precautions & Warnings:

Pregnancy: Peony is possibly unsafe when taken by mouth during pregnancy. It might cause uterine contractions. Until more is known, don't use peony during pregnancy.

Breast-feeding: There isn't enough reliable information to know if peony is safe to use while breast-feeding. Stay on the safe side and avoid use.

Children: Peony is possibly safe when taken by mouth for up to 12 months by children at least 1 year old.

Bleeding disorders: Peony might slow blood clotting. Don't use it if you have a bleeding disorder.

Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Peony extract might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don't use peony.

Surgery: Peony might slow blood clotting. This might increase the chance of bleeding during and after surgery. Stop using peony at least 2 weeks before a scheduled surgery.
