The emergence of real notoginseng (pure seven)
Panax notoginseng is the dried root and rhizome of Panax notoginseng. ) F.H. Chen of Araliaceae is mainly produced in Wenshan, Yunnan, Tian Yang, Jingxi, Baise and other places. It is large, heavy, firm and slippery, and its cross section is grayish green or yellowish green. Generally, it is harvested 3-4 years after planting and excavated before flowering in autumn, which is called "Spring Qi", full and strong, solid and not empty, with good quality; After flowering and fruiting in winter, it is called "Winter Seven", which is shriveled, emaciated, shriveled, sparse and loose, with poor quality.
Notoginseng medicinal materials are classified according to the quantity of each 500g, generally weighing more than 20 heads, such as 20 heads, 30 heads, 40 heads and 60 heads. The fewer heads, the higher the grade, and the fourth class (60 heads) is the most commonly used. Individual merchants will assemble Panax notoginseng with glue to improve the quality of medicinal materials. Sanqi is ground into fine powder, which is called "Sanqi".
Three-step identification method of panax notoginseng
A look at the shape:
Conical or cylindrical, the surface is grayish brown or grayish yellow, with intermittent longitudinal wrinkles and root marks. There are stem marks on the top and tumor-like processes around. Thin, not full contraction, sparse edema may be "winter seven"; There are obvious ligature marks on the surface, and some residual rubber bands may be "assembling Sanqi".
Second, look at the section:
Solid texture, gray-green, yellow-green or gray-white cross section. If the cross section is white, it means that the flesh of Panax notoginseng is insufficient, and it may have been sick during its growth. The light yellow part may be forged.
Three flavors:
Slight breathing, extremely bitter taste, immediately sweet, generally not as bitter as the throat. If it is not sweet or spicy, it may be a fake. In addition, Panax notoginseng should be dried to the extent of "leaving no trace of teeth", and it is not easy to preserve if the water content is too high.

Three-step identification method of panax notoginseng
Look at the color:
Grayish yellow. Too yellow may be processed from the velvet roots of Panax notoginseng, too white may be mixed with rice flour, and green may be mixed with fine powder of Panax notoginseng leaves.
The second taste:
Bitter tastes sweet. It tastes extremely bitter, but it should be sweetened immediately, otherwise it may be a fake.
Three blisters:
Put notoginseng in water, shake well and let it stand. The foam should be white, uniform and last for several hours. Adulterated people have fewer bubbles, which will disappear after standing for a period of time (note: the finer the grinding of Panax notoginseng, the more bubbles).

1, the difference in brewing
The real panax notoginseng will bubble a lot, and it is difficult to stir it evenly. This is because Panax notoginseng is rich in Panax notoginseng saponins, which is a surfactant, and the most obvious characteristic reaction is foaming. If there is no foaming, it is pseudo-notoginseng, and less foaming means less saponin content.
2. Different tastes
The real entrance of panax notoginseng is extremely bitter, but the bitterness will not stay in the mouth for a long time. It can be summarized in five words: the mouth can't reach the throat, that is, it can't reach the throat. If you think your throat is bitter or spicy, don't think too much, it's fake.
3, the color difference
The normal color of Panax notoginseng is not white or green, but gray, and the color of Panax notoginseng is abnormal. Most of the green Panax notoginseng is added with leaves or stems of Panax notoginseng; Whitening is close to the color of wheat flour, which may be mixed with rice flour or flour; Notoginseng, which is too yellow in color, may not be washed before pulverizing, or it may be processed with notoginseng velvet roots, which is neither hygienic nor safe, and its efficacy is not guaranteed.

In recent years, Wenshan Sanqi has become a popular Chinese medicine for health preservation, bringing good news to many friends suffering from cardiovascular and cerebrovascular diseases. However, good things are often easy to attract imitation, some are shoddy, some are fake, and many unscrupulous traders make profits that are harmful to human health, leading to death. Therefore, it is very important to know about pearls. How to distinguish the quality of Sanqi?
The key to identify the quality of Panax notoginseng at a glance is "the heart of a lion's head and a chrysanthemum".
"Copper skin" means that the surface of Panax notoginseng is as smooth as possible and as hard as copper. It can't be cut with a knife, and it is particularly hard to bite with teeth. If you hit it with a stone or iron, it will make a crisp sound! The surface is as hard as copper "iron bone" means that the internal structure of Panax notoginseng is as hard as iron, full, yellow-green, dark green, dark green and so on.
The flesh color of the "lion head" of Sanqi means that there are bumps around the position of Sanqi head, which are shaped like lions. It is said that pimples are propped up by panax notoginseng saponins, so the more pimples, the better the efficacy. The "chrysanthemum heart" of the lion's head Notoginseng cuts the cross section of Notoginseng, and the cross section inside is chrysanthemum-shaped, with one ring buckled. The color is normal, it is not black on a white background, and it is not hollowed out. Chrysanthemum heart slice
The routine is very deep. It is to sell high-priced money with low-priced Sanqi, take countless heads as 160 heads, and mix 20 heads with 40 heads.

Most importantly, the xylem and phloem are obviously separated (skin-bone separation, no fiber) when broken open with a hammer, showing a light green color.
