In China, ginseng has always been regarded as the king of all herbs.
Paleogeologists and paleontologists infer that ginseng is one of the oldest relict plant on earth. In the Tertiary period (65 million-1.8 million years ago) when angiosperms were extremely prosperous on earth, ginseng was widely propagated in the plant kingdom. It is recognized that ginseng is distributed between 33 and 48 degrees north latitude in the world. Records in Chinese herbal literature confirm that the distribution of Chinese ginseng is consistent with the history of paleogeology and paleontology.
Ginseng is a perennial perennial root herb. Its main root is 30-60cm high, thick, fleshy, yellowish-white, cylindrical or spindle-shaped, with slightly branched below. Rhizome (reed head) is short and erect.
Ginseng stem erect, cylindrical, unbranched; The annual plant has only one leaf at the top of its stem and three leaflets, commonly known as " three flowers"; The biennial stem is still only one leaf, but has 5 leaflets, which is called " slap"; The three-year-old has two opposite compound leaves with 5 leaflets, called " dicotyledons"; The number of four-year-olds increased to 3 compound leaves with whorls, called " Dengtaizi". The number of five-year-olds increased to four compound leaves with whorls, called " four leaves"; Six-year-olds have five whorled compound leaves on the top of their stems, called " five leaves."
