What is panax ginseng, and what is it used for?

Panax ginseng is an herbal supplement prepared from the root of the Panax ginseng plant. Panax ginseng is one of the most commonly used herbs in the world and has been used for thousands of years as a medicinal ingredient in traditional Chinese medicine.

Panax ginseng is an herbal adaptogen, a substance that is believed to help people adapt to and manage stress, anxiety, and fatigue, and is believed to enhance overall health, stamina and cognitive function.

The main active compounds in panax ginseng are ginsenosides and most studies have focused on the medicinal effects of ginsenosides. Panax ginseng, however, contains many other bioactive ingredients including phytosterols, sesquiterpenes, flavonoids, polyacetylenes, alkaloids, and phenolic compounds, and it is not clear if ginsenosides act alone or all these ingredients work together. Some of the ginseng products are now standardized to specific concentrations of ginsenosides.

Ginsenosides are believed to have antitumor, antioxidant and anti-inflammatory effects, and may produce therapeutic effects on various body systems including the nervous system, cardiovascular system and the immune system. Uses of panax ginseng include:

There is limited evidence that panax ginseng may have some effect in cognitive function, diabetes, erectile dysfunction and premature ejaculation, however, there is very little scientific evidence to support most of its other uses.

Panax ginseng is available as standardized extract capsules, dry root that can be brewed as tea, root powder that can be taken orally, and cream that can be applied on the penis for erectile dysfunction. Panax ginseng is also added to energy drinks, foods and skin care products.
