Panax notoginseng

Background

Panax notoginseng is a plant that grows in the mountains in Southwest China. Its root is sometimes used as medicine once it has grown for 3-5 years.

Panax notoginseng might relax blood vessels, which might improve blood flow and reduce blood pressure. Some of the chemicals in Panax notoginseng might also reduce swelling and protect the heart.

People use Panax notoginseng for chest pain, stroke, heart attack, bleeding, high blood pressure, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse Panax notoginseng with other plants with similar names, including Panax ginseng and American ginseng. These are not the same.
When taken by mouth: Panax notoginseng is possibly safe when used for up to 6 weeks. It's usually well-tolerated. Side effects might include dry mouth, flushed skin, insomnia, nausea, and rash.

When given in the rectum: There isn't enough reliable information to know if Panax notoginseng is safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Panax notoginseng is likely unsafe when taken by mouth while pregnant or breast-feeding. One of the chemicals in Panax notoginseng has caused birth defects in animals. Avoid use.

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