Overview

Panax ginseng, also known as Korean ginseng, is an herb that has been used for various health purposes. It should not be confused with other forms of ginseng.

Panax ginseng is a plant that grows in Korea, China, and Siberia. It's considered an adaptogen, which are natural substances that are believed to stimulate the body's resistance to stressors. Panax ginseng contains many active chemicals. The most important are called ginsenosides or panaxosides.

Panax ginseng is taken by mouth for memory and thinking skills, Alzheimer disease, depression, and many other conditions, but there is no good scientific evidence to support many of these uses.

Don't confuse Panax ginseng with other plants sometimes referred to as ginseng like American ginseng, Blue Cohosh, Canaigre, Codonopsis, Eleuthero, or Panax Notoginseng. These are different plants with different effects.

Uses & Effectiveness ?

Possibly Effective for

  • Memory and thinking skills (cognitive function). Taking Panax ginseng by mouth might improve thinking, arithmetic skills, and reaction times in healthy, middle-aged people but not in young adults. Taking panax ginseng alone doesn't seem to help memory, but taking it with ginkgo leaf extract seems to improve memory in healthy people between the ages of 38 and 66.
  • Erectile dysfunction (ED). Taking Panax ginseng by mouth seems to improve sexual function in adults with ED.
  • Flu (influenza). Taking a specific Panax ginseng extract by mouth appears to reduce the risk of getting a cold or the flu. But it doesn't seem to reduce flu symptoms or the length of the illness.
  • Fatigue in people with multiple sclerosis (MS). Taking Panax ginseng by mouth daily for 3 months reduces feelings of tiredness and improves quality of life in females with MS.
  • Increasing response to sexual stimuli in healthy people. Taking Panax ginseng alone or with other ingredients by mouth seems to improve sexual arousal and satisfaction in postmenopausal adults. It also seems to improve sexual desire in females who report sexual problems.

Possibly Ineffective for

  • Athletic performance. Taking Panax ginseng by mouth for up to 8 weeks doesn't improve athletic performance.
There is interest in using panax ginseng for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.

Side Effects

When taken by mouth: Panax ginseng is likely safe when taken for up to 6 months. Panax ginseng is possibly unsafe when taken for more than 6 months. It might have some hormone-like effects that could be harmful when used long-term. The most common side effect is trouble sleeping. Uncommon side effects that have been reported include severe rash, liver damage, and severe allergic reactions.

When applied to the skin: There isn't enough reliable information to know if Panax ginseng is safe. It might cause side effects such as irritation and burning.

When applied to the skin: There isn't enough reliable information to know if Panax ginseng is safe. It might cause side effects such as irritation and burning. Pregnancy: Panax ginseng is possibly unsafe when taken by mouth during pregnancy. One of the chemicals in Panax ginseng has been found to cause birth defects in animals. Do not use Panax ginseng if you are pregnant.

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

Children: Panax ginseng is likely unsafe in infants and children. Panax ginseng has been linked to fatal poisoning in newborns. It's not clear if it's safe in older children. Until more is known, do not use Panax ginseng in children.

"Auto-immune diseases" such as multiple sclerosis (MS), lupus (systemic lupus erythematosus, SLE), rheumatoid arthritis (RA), or other conditions: Panax ginseng seems to increase the activity of the immune system. It might make auto-immune diseases worse. Don't use Panax ginseng if you have any auto-immune condition.

Bleeding conditions: Panax ginseng seems to interfere with blood clotting. Don't use Panax ginseng if you have a bleeding condition.

Heart conditions: Panax ginseng can affect heart rhythm and blood pressure slightly on the first day it is used. Use Panax ginseng with caution if you have heart disease.

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

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

Suppressed immune system: Panax ginseng might make the immune system more active. This could interfere with the effects of medications that suppress the immune system, such as those given after an organ transplant. If your immune system is suppressed, don't use Panax ginseng.

Schizophrenia: High doses of Panax ginseng have been linked with sleep problems and agitation in people with schizophrenia. Be careful when using Panax ginseng if you have schizophrenia.
