American Ginseng

Overview

American ginseng (Panax quinquefolis) is an herb that grows mainly in North America. Wild American ginseng is in such high demand that it has been declared a threatened or endangered species in some states in the United States.

People take American ginseng by mouth for stress, to boost the immune system, and as a stimulant. American ginseng is also used for infections of the airways such as colds and flu, for diabetes, and many other conditions, but there is no good scientific evidence to support any of these uses.

You may also see American ginseng listed as an ingredient in some soft drinks. Oils and extracts made from American ginseng are used in soaps and cosmetics.

Don't confuse American ginseng with Asian ginseng (Panax ginseng) or Eleuthero (Eleutherococcus senticosus). They have different effects.

How Does It Work?

American ginseng contains chemicals called ginsenosides that seem to affect insulin levels in the body and lower blood sugar. Other chemicals, called polysaccharides, might affect the immune system.

Uses

  • Diabetes. Some research shows that taking American ginseng by mouth, up to two hours before a meal, can lower blood sugar after a meal in patients with type 2 diabetes. Taking American ginseng by mouth daily for 8 weeks might also help lower pre-meal blood sugar levels in patients with type 2 diabetes.
  • Infection of the airways. Some research suggests that taking a specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) 200-400 mg twice daily for 3-6 months during flu season might prevent cold or flu symptoms in adults. In adults older than 65, a flu shot at month 2 along with this treatment is needed to decrease the risk of getting the flu or colds. In people who do get the flu, taking this extract seems to help make symptoms milder and last for less time. Some research shows that the extract might not reduce the chance of getting the first cold of a season, but it seems to reduce the risk of getting repeat colds in a season. It does not seem to help prevent cold or flu-like symptoms in patients with weakened immune systems.

Recommended Dosing

The following doses have been studied in scientific research:

BY MOUTH:

  • For diabetes: 3 grams up to 2 hours before a meal. 100-200 mg of American ginseng has been taken daily for up to 8 weeks.
  • For infection of the airways: A specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) 200-400 mg twice daily for 3-6 months has been used.
