Traditionally the wild root was consumed to vitalize, strengthen, and rejuvenate the entire body. Widely cultivated, ginseng is now used as a natural preventive, restorative remedy and valued for its adaptogenic properties.
Korean ginseng is most suitable for males and older people.
Ginseng extracts have been shown to have antioxidant activity and to protect against radiation damage. European clinical trials have found an increase in reaction times, alertness, concentration, and visual and motor coordination. Rb1 group of ginsenosides have more sedative and metabolic effects on the central nervous system, while the Rg1 group of ginsenosides are more arousing and stimulating at low doses. These activities contrast with those of Rg1 ginsenosides which have weak CNS-stimulating activity, protect against fatigue, and cause an increase in motor activity. Both Rg1 and Rb1 ginsenosides act on the adrenal and pituitary glands and help them respond to stress more rapidly.
