American ginseng is known by the Chinese as the "cooling" ginseng, because it
stimulates the Yin. It is believed to be more effective in combating the effects
of stress than Korean ginseng, which is considered warming and stimulates the
Yang.
Ginseng has traditionally been used to treat insomnia, nervous dyspepsia,
stomach cramps, and other signs of stress. Because of its ability to reduce
stress, some herbal specialists consider ginseng as part of the treatment for
depression. A study of 501 men and women in Mexico City found significant
improvements in quality of life measures (energy, sleep, sex life, personal
satisfaction, well-being) in those taking American ginseng.
Animal experiments have demonstrated the ability of American ginseng root powder
to significantly reverse acute stress-induced changes in spleen weight and
plasma and stress-associated plasma enzymes (ALT, AST, and CK). It also
significantly reversed chronic stress-induced gastric ulcers and adrenal gland
weight changes.
Stress can to lead to the development of many types of diseases. The adrenal
gland is an indispensable organ that responds to stress. It secretes
catacholamines and cortisol which stimulate the body to respond to stress.
However long term or excessive stress results in over-secretion of
catecholamines and cortisol, leading to over-reaction and exhaustion of the
organs. This results in gastrointestinal symptoms (anorexia, dyspepsia, gastric
ulcer etc), fatigue, psychoneurosis (anxiety, depression, amnesia etc),
hypertension and immunosuppression.
Laboratory experiments show that the
ginsenoside fraction of ginseng (mainly the protopanaxatriols), and in
particular Rg2 and the metabolite M4, reduce the secretion of catecholamines by
the adrenal gland. American ginseng appears to inhibit catecholamine secretion
by blocking acetylcholine induced sodium ion influx into the cells through
nicotinic acetyl choline receptor-operated cation channels.
