Ginseng, a perennial herb, like a cool, moist climate, more growth in the small diurnal temperature of 500 to 1100 m altitude mountain ramp or slope land in conifer or weed. Because the roots of the mast, if the spindle-shaped, often forked, picture resembling the man's head, hands, feet and limbs, and therefore called ginseng. Ancient Ginseng called Ya Huang Jing, goblins, God grass. Ginseng is known as the "King of Herbs" is the famous "Northeast Sambo" (ginseng, mink, deer horn), one
From red ginseng, ginseng or white ginseng were isolated more than 30 kinds of ginsenosides (can be divided into three groups, namely oleanolic acid group, and the original protopanaxdiol Panaxatriol group), are called ginsenosides (Ginsenoside) -RX (Note: X = 0, a1, a2, a3, b1, b2, b3, c, d, e, f, g1, g2, g3, h1, h2, h3, s1, s2), still false ginsenosides (Pseudoginsenoside saponin) F11 and so on. Ginseng saponin material basis of physiological activity. Protopanaxadiol (Protopanaxadiol) and the original Panaxatriol (Protopanaxatriol) is ginsenosides exist in the original form, in the separation of aglycone, the role of acid and hydroxyl side chain part of the molecule and the ethylenic cyclization From panaxadiol (Panaxadiol) and Panaxatriol (Panaxatriol), panaxadiol and Panaxatriol are triterpenoids.
Ginseng can adjust the balance of the central nervous system stimulant and inhibitory processes process. By studying the influence of ginseng animal EEG activity, the results showed that: two of its excitatory and inhibitory neural processes affected both, but mainly to strengthen the excitement of the cerebral cortex. Because at the same time acting on the inhibition process, it tends to focus on the inhibition, making differentiation accelerated and more complete. Ginseng can regulate nerve function, so nervous disorders caused by neural processes are restored.
Ginseng on cerebral blood flow and cerebral energy metabolism also significantly affected. Ginseng preparation can increase glucose uptake in rabbit brain, while reducing the ratio of lactate, pyruvate and lactate / pyruvate and glucose utilization make the transition from anaerobic to aerobic metabolism pathway. Ginseng also make the cerebral cortex of free inorganic phosphate increased by 25%. Ginseng fruit saponins can improve brain oxygen uptake capacity. Ginsenosides, ginseng root saponins on cerebral ischemia / reperfusion injury have a protective effect.
