Wild ginseng is called "wild ginseng" and cultivated ginseng is called "garden ginseng". The difference between them in medicinal materials is as follows:
Wild ginseng: a dense reed bowl on the upper part of the rhizome, and a long reed on the lower part of the rhizome. There is a thin and deep dense spiral at the upper end of the main root. Generally, there is no grain in the middle and lower parts. The fibrous roots are sparse and long, and are not easy to break. There are obvious verrucous protrusions on it.
Garden ginseng: there is a reed bowl on one or both sides of the rhizome, but there is no garden reed. There are thick horizontal stripes on the upper end of the taproot, which are not spiral, and sometimes horizontal stripes can be seen all over the body. The fibrous root is broom-shaped, short and brittle, and there is no obvious wart on it.
