Ginseng, a perennial herbaceous plant with a cool, humid climate, grows mostly in coniferous and broad-leaved mixed forests or in mixed forests on alpine slopes with 500 to 1,100 meters above sea level.
Flavor function: Gan, slightly bitter. Mild temperature, qi, Shengjin soothe the nerves, Qi, containing a variety of saponins and polysaccharides. The research report of the reference class points out that most of the ginseng is produced in Jilin Changbai Mountains, Liaoning, Heilongjiang, Hebei, Shanxi and Hubei.
The growers are "ginseng" and the wild are "ginseng." More than the autumn excavation, washing; garden ginseng after drying or drying, known as "raw sun ginseng"; ginseng dried, called "sun ginseng," after steaming, drying, said "red ginseng" . Red ginseng: Steam with high-temperature steam for 2 hours until fully cooked, remove the ginseng after drying, and press into an irregular square column. Efficacy: Warming. White ginseng: Choose ginseng that is short and of inferior quality, boil for a while with boiling water, and then dry. Efficacy: mild. Let's take a look at the efficacy and role of ginseng.
The efficacy and role of ginseng
1 Regulation of the central nervous system
Ginseng can regulate the central nervous system, improve the brain's excitement and inhibition process, and make it more balanced; it can improve the mental and physical labor ability, improve work efficiency, and have anti-fatigue effect.
2 Promote the use of energy substances in the brain, can improve learning and memory ability The effective component of ginseng to enhance learning and memory ability is ginsenosides, among which ginsenosides rb1 and rg1 have good effects on learning and memory functions.
3 Improve heart function
Ginseng can increase myocardial contractility, slow heart rate, increase cardiac output and coronary blood flow, anti-myocardial ischemia and arrhythmia. Has a certain influence on heart function, cardiovascular, and blood flow. Ginseng has obvious hypoxic tolerance and its preparation can effectively counteract sinus arrhythmia. Ginsenosides can accelerate lipid metabolism and have a significant effect of lowering high cholesterol. Small doses of ginseng can increase blood pressure in anesthetized animals, while high doses decrease blood pressure. Different ginseng preparations enhance the function of the isolated heart and heart of rabbits, cats, and dogs, and can improve myocardial weakness during ventricular fibrillation .
4 hypoglycemic effect
Ginseng contains ginsenosides and ginseng polysaccharides. In particular, ginsenoside rb2 has a significant hypoglycemic effect, and ginseng polysaccharides (or glycopeptides) are another hypoglycemic component of ginseng.
5 Enhance the body's immune function
Ginseng saponins and ginseng polysaccharides are active ingredients of ginseng to regulate immune function, and not only to normal people but also to immunocompromised individuals. Ginseng polysaccharide is a high-molecular acid polysaccharide purified from ginseng and is an immunopotentiator. After animal experiments and human clinical experiments, it has been confirmed that it can significantly enhance human immunity, and has a certain curative effect on malignant tumors; clinical experiments can also prolong the patient's survival time, improve the body's cellular immune function, and reduce the toxic side effects of radiotherapy and accelerate the damage tissue. Repair. After clinical observation, it was confirmed that ginseng polysaccharide has obvious leukocyte-increasing effect, and it can be used concurrently with radiotherapy and chemotherapy to reduce the toxic and side effects of radiotherapy and prevent leucopenia and enable patients to complete treatment successfully. There are no side effects in the application of ginseng polysaccharides, which proves that the drug is safe and reliable.
6 Improve the ability to resist harmful stimuli, enhance the body's stress and adaptability
Ginseng contains ginseng glycosides, which can increase anti-stress effects. It is resistant to hypoxia, high temperature and low temperature.
7 Anti-tumor effect
Ginsenosides in ginseng, ginseng polysaccharides, ginsenosides, ginsenoside triols, and volatile oils. These substances have a certain inhibitory effect on tumors, but the mechanism is very complicated.
8 Antioxidant effect
Ginseng contains a variety of antioxidants, ginsenosides, ginseng polyacetylene compounds, and panaxadiol saponins. These compounds have anti-lipid peroxidation and are the basis of anti-aging effects. In addition to its anti-aging effects, it regulates neurological, endocrine, immune functions, and substance metabolism. In addition, ginseng also has anti-virus, anti-shock, weight loss and many other aspects. Although ginseng is a high-value supplement, it is not suitable for everyone. Protein factors in ginseng can inhibit lipolysis and aggravate vascular wall lipid deposition. Therefore, ginseng should be treated with caution in patients with coronary heart disease, hypertension, cerebral vascular sclerosis, diabetes, and vasculitis. Increased blood viscosity will cause poor blood circulation. Chinese medicine calls it blood stasis. Ginseng has the effect of promoting the growth of red blood cells, with an increase in red blood cells and a thicker blood station.
