GINSENG - AMERICAN (Panax quinquefolium)
COMMON NAME : Ginseng, American ginseng
LATIN NAME : Panax quinquefolium
DESCRIPTION : Panax quinquefolium is a deciduous perennial shrub whose fleshy root requires 4 years of cultivation to reach maturity. Traditionally the wild root was consumed by American Indians as a general tonic, as a natural restorative for weak and wounded, and to help the mind. American ginseng is now used as a natural preventive and restorative remedy and valued for its adaptogenic properties. American ginseng (Panax quinquefolium) is more sedative and relaxing and increases "yin" energy while Korean ginseng is more stimulating and increases the "yang" energy. American ginseng is suitable for females and young people as well as males and older people.
PHYSIOLOGY : The main active ingredients of ginseng are the more than 20 saponin triterpenoid glycosides called ginsenosides whose names relate to their chromatographic position (Ra, Rb, etc.). American ginseng is rich in the Rb1 group of ginsenosides which have more sedative and metabolic effects on the central nervous system, compared to the Rg1 group of ginsenosides which are more arousing and stimulating. Rb1 Ginsenosides have CNS-depressing activity, have weak anti-inflammatory action, and increase digestive tract peristalsis. Laboratory animals given Rb1 ginsenosides have improved stamina and increased learning abilities. Other studies have shown that Rb1 ginsenosides also have anti-fatigue, anti-convulsant, antipyretic, antipsychotic, analgesic, and ulcer protective effects.
ACTIVE PROPERTIES : American ginseng has been used for stress and fatigue characterized by insomnia, poor appetite, nervousness, and restlessness. The root has been used for conditions of weakness, convalescence, low resistance, poor immunity or debility due to chronic disease. Scientific support is now emerging for its use in the regulation of various metabolic disturbances including blood sugar and lipid levels.
