First, fresh ginseng must know the five functions:
1, cardiotonic, anti-hypoxia, anti-myocardial ischemia and anti-arrhythmia.
Ginseng can increase myocardial contractility, slow down heart rate, increase cardiac output and coronary blood flow, resist myocardial ischemia and arrhythmia and improve myocardial weakness. Fresh ginseng has obvious anti-hypoxia effect and can effectively fight against sinus heart rate abnormality.
2. Fresh ginseng can lower blood sugar and blood fat.
Ginsenoside Re contained in fresh ginseng is the main component of lowering blood sugar. Ginsenoside Re has insulin-like effect and can lower blood sugar. Ginsenoside Rb 1, another main component of ginseng, has the function similar to insulin sensitizer, which can enhance the activity of insulin, make insulin work, and thus lower blood sugar. At the same time, ginsenoside can accelerate lipid metabolism and significantly reduce high cholesterol.
3, enhance the body's resistance, improve the effect of radiotherapy and chemotherapy, and fight cancer.
Ginsenosides and ginseng polysaccharides are active components in fresh ginseng to regulate immune function, which not only have the effect and function of improving immune function for normal people, but also for people with low immune function, and have a good preventive effect on chills and colds. In addition, clinical experiments show that fresh ginseng can prolong the survival time of patients, improve the cellular immune function of the body, reduce the side effects of radiotherapy and accelerate the repair of damaged tissues. Ginseng polysaccharide has obvious effect of increasing white blood cells. When combined with radiotherapy and chemotherapy, it can reduce the toxic and side effects of radiotherapy, prevent leukopenia, and enable patients to successfully complete treatment.
4. Enhance memory, concentrate, resist fatigue and prevent Alzheimer's disease.
Ginsenosides Rb 1 and Rg 1, the effective components of fresh ginseng, can promote the utilization of energy substances in the brain, improve the ability of memory, learning and body imitation, improve memory decline, learning disabilities and forgetfulness, alleviate various brain disorders caused by aging and prevent Alzheimer's disease. Fresh ginseng can regulate the central nervous system, improve the excitement and inhibition process of the brain, and make it tend to be balanced; Can improve mental and physical labor ability, improve work efficiency, and has anti-fatigue effect.
5, longevity beauty
Fresh ginseng can transform splinter cell in aging cells into splinter cell, shortening the cell division cycle, thus having anti-aging effect.
Fresh ginseng has comprehensive effects and outstanding functions, and it is a necessary item for middle-aged and elderly people to keep healthy. Eating fresh ginseng scientifically for a long time will make you feel strong and get a second spring in life.
Second, how to identify ginseng
1. The taproot of wild ginseng (Panax ginseng) is as long or short as the rhizome, with a length of 3- 10 cm, which is herringbone, cylindrical or rhombic; The surface color is grayish yellow with longitudinal stripes. Ginseng has tight and deep annular stripes at the upper end, slender and clear fibrous roots, and two branches at the lower part, with obvious warty protrusions, commonly known as "pearl bumps". The rhizome is thin and long, with dense stem marks on the upper part, and the adventitious roots are thick, shaped like jujube pits.
2. The main roots of cultivated ginseng are cylindrical or spindle-shaped, with a diameter of 1-2cm and a length of 3- 15cm. Its surface is yellow, with obvious longitudinal wrinkles and sparse, intermittent thick horizontal stripes on the upper part or the whole, and 2-3 branch roots on the lower part, with many slender fibrous roots and usually inconspicuous small verrucous protrusions. The rhizome (reed head) has a diameter of 0.3- 1.5cm and a length of 1-4cm, which is spiral with adventitious roots and concave sparse stem marks. There are yellow-brown punctate resin grooves and radial cracks on the skin. If the texture is hard, cut it off, the color of its section is yellow-white powder, and the ring pattern of its cambium is brown; Special aroma, slightly bitter and slightly sweet taste.
3. The roots of Arctium lappa L. are oblong, hammer-shaped or spindle-shaped. The surface is brown, the root branches are few, there are obvious longitudinal wrinkles and furrows, and the skin is yellowish brown. Tough, after truncation, its cross section is translucent; The cambium ring is obvious; Its wood is yellow and white, and radial texture can be seen. The gas is slightly bitter.
4. Radix Dipsaci is long and cylindrical, branched, with grayish yellow surface, fine longitudinal stripes and horizontal lenticels, fibrous roots and fibrous root marks. Hard, yellow-white cross section, fibrous, often with large cracks, wood with radial texture, sometimes hollow. The gas is slightly fragrant and bitter.
5. The root of Allium chinense is long and cylindrical, with yellow-brown surface and 1-2 branches or no branches. Length 30-40 cm. The head near the root has a horizontal ring pattern, and the middle and lower parts have obvious longitudinal wrinkles and grooves, which are twisted. Tough and horny. After truncation, the epidermis of the section is narrow and yellowish brown, and the cambium ring is brown; The wood is wide, yellow and white, with radial texture. Slight gas, sweet taste.
6. The main root of the counterfeit product Polygonum hydropiper is relatively long and straight, and its surface is grayish yellow, which is about 4 cm long with intermittent ring lines at the upper end and obvious longitudinal wrinkles at the lower end. Fibrous roots are few, short and brittle, with three branches, and the verrucous processes of the branches are not obvious. There are sparse bowls on the head of the reed, which are staggered and have three cis-forms. If you look closely, you can see that the taproot, reed head, branch root and fibrous root are all forged by processing, bonding and forging, and blisters will be scattered.
There are many kinds of fresh ginseng, and the processed commodity ginseng is dazzling and colorful. How to identify ginseng, its quality is good or bad, is a science and can be learned. A brief understanding of the identification knowledge of ginseng will help us avoid being deceived when choosing ginseng.
