Ginseng is a very precious medicinal material. There are many kinds of ginseng in the market with different qualities, so it is necessary to learn some identification knowledge. Among ginseng, only wild ginseng is a precious medicinal material, and its growth period ranges from several decades to more than a hundred years, so it is expensive. Because the yield of ginseng is scarce, the phenomenon of passing the fake as the real and passing the inferior as the good occurs from time to time, so attention should be paid to identification. In order to identify ginseng well, we must master the following points: we must not only see the "five shapes" clearly, but also identify the "six bodies" Five shapes refer to whiskers, reeds, skins, lines, and bodies (1) whiskers: long and thin, long and long, with millet-shaped pimples, which are called "pearl spots". Those who are white and tender (commonly known as water beard) are not pure wild ginseng. (2) Reed: Reed is long and divided into two-section reed, three-section reed, line reed and wild-necked reed. Two-section reed-there are horse-tooth reed and round reed. Three-section reed-there are horse-tooth reed, round reed and piled reed. The so-called horse tooth reed is characterized by obvious stem marks on the rhizome, which are shaped like horse teeth, mostly in the upper part of the rhizome. The so-called round reed is that the stem mark on the rhizome grows flat and cylindrical with age. The so-called wild goose-neck reed is slender and slightly curved, like a wild goose-neck. The so-called line reed is because of its long age, the reed bowl on the rhizome is long and flat, and the rhizome is thin and long. (3) Leather: Old leather, yellow-brown, compact and shiny. Those who are tender and white are not pure ginseng. (4) Striation: There are fine and deep screw-like horizontal stripes at the upper shoulder of the hair root. Those whose stripes are rough, superficial and incoherent are not pure ginseng. (5) Body: refers to hairy roots (see six bodies).
