What is it?

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.

The effectiveness ratings for PANAX GINSENG are as follows:

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.
