GINSENG, AMERICAN Overview Information

American ginseng is an herb. The root is used to make medicine.

American ginseng is used for stress, to boost the immune system, and as a general tonic and stimulant.

American ginseng is often used to fight infections such as colds and flu. There is some evidence that it might help prevent colds and flu and make symptoms milder when infections do occur.

American ginseng is used for other infections including HIV/AIDS, infections of the intestine (dysentery), and particular infections (Pseudomonas infections) that are common in people with cystic fibrosis.

Some people use American ginseng to improve digestion and for loss of appetite, as well as for vomiting, inflammation of the colon (colitis), and inflammation of the lining of the stomach (gastritis).

American ginseng is also used for low iron in the blood (anemia), diabetes, trouble sleeping (insomnia), nerve pain, erectile dysfunction (ED), fever, hangover symptoms, attention deficit-hyperactivity disorder (ADHD), blood and bleeding disorders, cancer, painful joints, dizziness, headaches, convulsions, fibromyalgia, “hardening of the arteries” (atherosclerosis), memory loss, and as an anti-aging aid.

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 Siberian ginseng (Eleutherococcus senticosus) or Asian ginseng (Panax ginseng). They have different medicinal effects.

Wild American ginseng is becoming rare because it is so popular and has so many uses. Some states have declared American ginseng a threatened or endangered species because so many people try to harvest it.

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.

GINSENG, AMERICAN Uses & Effectiveness What is this?

Possibly Effective for:

  • Diabetes. Taking 3 grams of American ginseng by mouth, up to two hours before a meal, can lower blood sugar after a meal in patients with type 2 diabetes. However, larger doses do not seem to lower blood sugar more. Different American ginseng products may have different effects. Researchers think that is because they contain different amounts of the active chemicals called ginsenosides.
  • Respiratory tract infections. Some evidence suggests that taking a specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences, Canada), 200 mg twice daily over a 3-4 month period during flu season, might prevent cold or flu symptoms in adults between the ages of 18 and 65. People older than 65 seem to need a flu shot at month 2 along with this treatment in order to decrease their risk of getting the flu or colds. This extract also seems to help make symptoms milder and last a shorter length of time when infections do occur. Some evidence suggests 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.

Possibly Ineffective for:

  • Athletic performance. Taking 1600 mg of American ginseng by mouth for 4 weeks does not seem to improve athletic performance; however, lab tests show that it might decrease muscle damage during exercise.
  • High blood pressure. Research suggests that taking 3 grams of American ginseng daily for up to 12 weeks does not affect blood pressure in people with high blood pressure.

Insufficient Evidence for:

  • Attention deficit-hyperactivity disorder (ADHD). There is early evidence that a specific product (AD-fX, Afexa Life Sciences, Canada), containing American ginseng extract in combination with ginkgo leaf extract, might help improve ADHD symptoms such as anxiety, hyperactivity, and impulsiveness in children aged 3-17 years.
  • Breast cancer. Some studies conducted in China suggest that breast cancer patients treated with any form of ginseng (American or Panax) do better and feel better. However, this may not be a result of taking the ginseng, because the patients in the study were also more likely to be treated with the prescription cancer drug tamoxifen. It is difficult to know how much of the benefit to attribute to ginseng.
  • Cancer-related fatigue. Early research suggests that taking 700-2000 mg of American ginseng daily for 8 weeks does not reduce fatigue in people with cancer.
  • Mental performance. Some evidence suggests that taking one 100-400 mg dose of American ginseng improves short-term memory and reaction time before a mental test.
  • Menopausal symptoms. Early evidence suggests that taking a product containing American ginseng, black cohosh, dong quai, milk thistle, red clover, and chasteberry tree (Phyto-Female Complex) twice daily for 3 months reduces menopausal symptoms, including hot flashes, night sweats, and sleep quality.
  • Stress.
  • Anemia.
  • Insomnia.
  • Gastritis.
  • Impotence.
  • Fever.
  • HIV/AIDS.
  • Fibromyalgia.
  • Other conditions.
More evidence is needed to rate the effectiveness of American ginseng for these uses.


GINSENG, AMERICAN Side Effects & Safety

American ginseng is POSSIBLY SAFE in adults and children when used short-term. It can cause some side effects including diarrhea, itching, trouble sleeping (insomnia), headache, and nervousness. In some people, American ginseng might also cause rapid heartbeat, increased blood pressure or decreased blood pressure, breast tenderness, vaginal bleeding in women, and other side effects. Uncommon side effects that have been reported include a severe rash called Stevens-Johnson syndrome, liver damage, and severe allergic reaction.

Special Precautions & Warnings:



Pregnancy and breast-feeding: American ginseng is POSSIBLY UNSAFE in pregnancy. One of the chemicals in Panax ginseng, a plant related to American ginseng, has been linked to possible birth defects. Do not take American ginseng if you are pregnant.

Not enough is known about the safety of American ginseng during breast-feeding. Stay on the safe side and avoid use.

Diabetes: American ginseng might lower blood sugar. In people with diabetes who are taking medications to lower blood sugar, adding American ginseng might lower it too much. Monitor your blood sugar closely if you have diabetes and use American ginseng.

Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: American ginseng preparations that contain chemicals called ginsenosides might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don’t use American ginseng that contains ginsenosides. However, some American ginseng extracts have had the ginsenosides removed (Cold-fX, Afexa Life Sciences, Canada). American ginseng extracts such as these that contain no ginsenosides or contain only a low concentration of ginsenosides do not appear to act like estrogen.

Trouble sleeping (insomnia): High doses of American ginseng have been linked with insomnia. If you have trouble sleeping, use American ginseng with caution.

Schizophrenia (a mental disorder): High doses of American ginseng have been linked with sleep problems and agitation in people with schizophrenia . Be careful when using American ginseng if you have schizophrenia.

Surgery: American ginseng might affect blood sugar levels and might interfere with blood sugar control during and after surgery. Stop taking American ginseng at least 2 weeks before a scheduled surgery.
