Ginseng belongs to the herbaceous family in biological species, so most of these plants contain tree-like rings, and ginseng can also be identified by this method. Generally speaking, ginseng with low tree age, such as ginseng under four years old, has no annual rings. Only when ginseng grows for more than four years can the annual rings be observed on the cross section. Let's take the common red ginseng as an example. Every time ginseng grows for six years, there will be two or three annual rings. Reed is the slender part at the top of the main root, also known as? Reuters? Rootstock, also known as underground stem. Every autumn, the aboveground part falls off, leaving a stem called rhizome, and its number increases with the age of ginseng, which is also the main index of ginseng age. Moreover, due to the continuous development of the environment and the influence of natural disasters, wild ginseng with long life is hard to find. But on the whole, it is always good to have a long and dense beard.
If the stems of ginseng are thick, and the iron lines on the surface of ginseng are thick and dense, and the skin is dark and black, it means that ginseng is very old. Generally speaking, ginseng has a very thin foundation. The roots are getting stronger and stronger, and the effect is getting better and better, such as nourishing the spleen and moistening the lungs, calming the nerves and improving intelligence.
Generally speaking, ginseng should be longer, longer, thicker and looser, as big as a small palm. These ginseng are usually correct. If it looks white, soft and tender, be careful. Even if he is really a ginseng, he is also a low-value ginseng planted in artificial greenhouses.
