Ginseng (American ginseng, Asian ginseng, Chinese ginseng, Korean red ginseng, Panax ginseng: Panax spp. including P. ginseng C.C. Meyer and P. quinquefolius L., excluding Eleutherococcus senticosus)


The term ginseng refers to several species of the genus Panax of the Araliaceae family. The two most commonly used ginseng species are Asian ginseng (Panax ginseng) and American ginseng (Panax quinquefolius). Panax species should not be confused with Siberian ginseng (Eleutherococcus senticosus), which is from a different plant family.
The word "ginseng" comes from ren-shen, the Chinese word for the plant, which means "essence of the earth in the form of a man" or "man-root," referring to the root's human-like shape.
Panax ginseng has been used in traditional Chinese medicine (TCM) for more than 2,000 years. Its uses include increasing appetite and strength, enhancing memory and physical performance, reducing fatigue and stress, and improving overall quality of life. Shengmai (also called shenmai) is a combination of Panax ginseng, Schisandra fruit, and Ophiopogon japonicus that has also been used in TCM to treat heart and respiratory diseases.
American ginseng has been used as a folk remedy by many Native American tribes, as a mild stimulant, digestive aid, and for ailments such as headache, female infertility, fever, and earache.
Ginseng has been used traditionally to treat cancer and, in modern times, to prevent cancer. Evidence supports ginseng use in decreasing cold symptoms, and improving mental performance.
The primary active parts of ginseng are ginsenosides. When purchasing ginseng products, experts suggest products labeled as Panax ginseng and standardized to 4-7% ginsenosides.

Note: This review is focused on Panax ginseng species. Kaempferia parviflora is referred to as Thai ginseng and is in the ginger family. It is not related to Panax ginseng and is not included in this bottom line. In Russia, Siberian ginseng has been advertised as a cheaper type of ginseng with identical benefits. However, it lacks the the same effects as the Panax ginseng. Other species may be referred to as ginseng as well, but they are different. Examples include: Eleutherococcus senticosus (Siberian ginseng), Pseudostellaria heterophylla (prince ginseng), Angelica sinensis (female ginseng, or dong quai), Withania somnifera (Indian ginseng or ashwagandha), Pfaffia paniculata (Brazilian ginseng), Lepidium meyenii (Peruvian ginseng or maca), and Gynostemma pentaphyllum (southern ginseng or jiaogulan). These species are not covered in this bottom line.
