''Ginseng'' is found only in the Northern Hemisphere, in North America and in eastern Asia (mostly Korea, northern China (Manchuria), and eastern Siberia), typically in cooler climates. ''Panax vietnamensis'', discovered in Vietnam, is the southernmost ginseng known. Ginseng is characterized by the presence of ginsenosides.

The English word ginseng derives from the Chinese term rénshēn (simplified: 人参; traditional: 人蔘). Rén means "man" and shēn means a kind of herb; this refers to the root's characteristic forked shape, which resembles the legs of a man.[2] The English pronunciation derives from a southern Chinese reading, similar to Cantonese jên shên (Jyutping: jan4sam1) and the Hokkien pronunciation "jîn-sim".

The botanical/genus name ''Panax'' means "all-heal" in Greek, sharing the same origin as "panacea", and was applied to this genus because Linnaeus was aware of its wide use in Chinese medicine as a muscle relaxant.

Besides Panax ginseng, there are many other plants which are also known as or mistaken for the ginseng root. The most commonly known examples are Xiyangshen, also known as American Ginseng 西洋参 (''Panax quinquefolius''), Japanese ginseng 东洋参 (''Panax japonicus''), crown prince ginseng 太子參 (''Pseudostellaria heterophylla''), and Siberian ginseng 刺五加 (''Eleutherococcus senticosus''). Although all have the name ginseng, each plant has distinctively different functions. However, true ginseng plants belong to the ''Panax'' genus.

Organoleptic Characteristics

[Panax ginseng (root)] has a feeble odor, and a sweet, slightly aromatic taste, somewhat analogous to that of licorice root.

Source: United States Dispensatory (1918) [1]

Macroscopic Characteristics

The root is fleshy, somewhat spindle-shaped, from 5 to 12 cm. long, and 1 to 2.5 cm. thick, and terminated by one or more stem scars. Frequently there are two portions, sometimes three or more, connected at their upper extremity, and bearing a supposed, though very remote, resemblance to the human figure, from which circumstance it is said that the Chinese name ginseng originated. When dried, the root is yellowish-white and wrinkled externally, and within consists usually of a hard central portion, surrounded by a soft whitish bark.
