Ginseng Types Compared: Asian, American, Siberian, Indian and Others

"Ginseng" on a label can mean more than one plant. Asian ginseng (Panax ginseng) and American ginseng (Panax quinquefolius) are different species. [1] "Siberian ginseng" is eleuthero, a different genus that LactMed says is not related to true ginseng, and "Indian ginseng" is ashwagandha, in a different family. [2][1][3] Because trials test one plant and one preparation at a time, a result for one type cannot be assumed for another. This page lists what the sources say about each. "Ginseng" is also called an adaptogen, a contested label; see what adaptogens are.

The types side by side

Scientific names were checked in the GBIF taxonomy on 2026-10-23. [1]

"Korean ginseng" is a common name NIH gives to Panax ginseng, so it is not the same as Siberian ginseng. [4] Red and white ginseng are the same plant prepared in two ways. [4] See red versus white ginseng.

Why the type matters: two documented examples

Blood sugar after a sugar drink. In a small crossover experiment, 12 healthy adults received 3 g of each of eight ginseng types before a glucose drink. Effects on blood sugar differed by type: Asian ginseng raised peak glucose, Siberian ginseng raised later glucose readings, and American and Vietnamese types tended to lower the 90-minute reading. [8] The authors concluded ginseng has variable glycemic effects, partly linked to its ginsenoside ratio. [8] This is one small experiment in healthy people, not a guide to use. More on the topic: ginseng, blood sugar and blood thinners.

Warfarin. A 4-week trial in 20 healthy people found American ginseng reduced warfarin's anticoagulant effect. [6] A separate crossover study of 12 healthy men found "ginseng" did not change warfarin's effect. [9] The two used different plants or preparations, so the results are not interchangeable. The second abstract names only "ginseng".

How the research differs by type

• Asian ginseng: NIH says the amount of research has grown but large, longer trials are still needed. [4]
• American ginseng: the evidence we read is mainly one large cancer-fatigue trial and the warfarin study. Beyond that: Proper evidence not found in the sources we read for this page. See American ginseng and the Asian versus American comparison.
• Siberian ginseng: the EU committee said shortcomings in study design prevented any firm conclusions. [7] It lists insomnia, irritability, rapid heartbeat and headaches as reported side effects. [7] See eleuthero and ginseng versus eleuthero.
• Indian ginseng (ashwagandha): NIH says some preparations may be effective for insomnia and stress, evidence on anxiety is unclear, and liver injury has been reported rarely. [3] See ashwagandha.

Reading a label

Look for the scientific name and the plant part, not just "ginseng". In a UK DNA-barcoding study, all 25 Siberian ginseng products contained E. senticosus, but 36% also contained another Eleutherococcus species. [10] Substitution or mixing was described as common in that study and in a set of rhodiola products. [10] It is one study of products sold in one country, not a rating of any product. See reading labels and quality testing and certifications. Traditions that use these roots are described at ginseng in Chinese medicine and in the American, Asian and Siberian comparison.
