The specific name ‘Ginseng’ is thought to originate from the Chinese names ‘Jin-chen’, ‘Jen-chen’ or ‘Schinseng’. There is an ongoing question over the labeling of some plants as "Ginseng". Currently, the word "Ginseng" is used to sell a variety of herbs associated with certain therapeutic qualities. This can be confusing as they do not all demonstrate the same biochemical properties. Panax, derived from a Greek word meaning cure-all, is thought by some to be the only "true" Ginseng, and is certainly the most famous.
A list of Relevant Ginseng types is given below:
| Genus Panax | Common Name |

Panax ginseng is indigenous to Manchuria, Chinese Tartary, and other areas of Eastern Asia. 1,2 By some it is considered one of the most utilized and highly regarded of the medicinal Chinese herbs, and its usage can be traced back over approximately 5,000 years.
It is a smooth herbaceous perennial belonging to the ivy family Araliaceae. It has a large, fleshy, and very slow-growing root which usually grows to 2 to 3 inches in length 1/2 to 1 inch in thickness. It is spindle-shaped and annulated with a round summit. The color is pale yellow to brown. It’s erect stem grows to over 1 foot and usually has three leaves divided by 5 leaflets and a singular terminal umbel. It produces bright red pea-sized berries in clusters. In the wild it can be found growing in the deciduous hardwood forests of Asia. It prefers shade and is slow to germinate both in captivity and the wild. Roots are usually harvested in the fall. It is thought that the roots should not be harvested until they are at least 5 years old or older for optimum medicinal strength [Ginsenoside (an active constituent) 3,4,5,6 content has been said to increase within the root up until it’s 6 th year, with slow or no increase from that point on]. In one study "the contents of panaxadiol-and panaxatriol-saponins gradually increase with the growth year, whereas an oleananesaponin, ginsenoside-Ro, drastically increases at the 6 th year and goes to 15-fold." 3
Originally harvested from the wild, now cultivated worldwide, ginseng mostly originates from China, Korea and Japan. Both the red and white varieties originate from the same genus, but are prepared differently. White ginseng is dried, and has been outperformed by red ginseng containing a higher content of saponins, and which is steamed before drying. Red Ginseng has been shown to contain a higher content of saponins and has outperformed white ginseng in most therapeutic studies. 7,8,9,25
Wild roots are thought to have stronger therapeutic qualities and at least one study backs this claim. 10 Even without further studies the wild roots sell for thousands of dollars each. The more the root resembles the human form, the higher the value. However, for most of us, roots that have been allowed to mature for 5 years or longer in good soil and environmental conditions, and harvested at the correct time of year 3,4,5,6 are thought to have stronger therapeutic qualities.
Other factors to be aware of when purchasing Ginseng is the diversity within the Genus. The healing abilities contributed to Ginseng may not be present in some or may be present but in significantly different potencies. A good example of this is the difference between Panax ginseng (documented as having 44 chromosomes) and Panax Japonicus (documented with 24). 173 Differences in DNA 11,12,13,14 and therefore biochemical constituents most probably mark a difference in the plant’s assigned healing characteristics.
Ginsenosides are usually considered the main constituents to the therapeutic effect of Ginseng (see Pharmacology and Clinical Studies), and when procuring the herb in forms other than the natural root (i.e. capsules, tonics, etc.), the amount and types of ginsenosides included should be noted. They include Rgl, Re, Rf, Rbl, Rc, Rb2 and Rd. Although not clinically documented it is thought that at least seven of these ginsenosides should be present within the product and in a high percentage. Improper storage or preparation of the herb is thought to reduce the ginsenoside content.
When purchasing Panax ginseng labels should be checked for clear identification of the plant genus utilized, as substitution occurs. Even if the correct genus is listed, toxic or stimulant adulterations, absence of the constituent ginsenosides, mixing species, labeling that is either erroneous or lacking in information make it adviseable to look for the U.S.P. notation on a product showing that the manufacturer follows standards established by the U.S. Pharmacopoeia.
Second to the raw herb concentrated and standardized products may be the most reliable. Also, carefully prescribed and utilized standardized product have, to date, shown little or no side effects while there have been reports of severe incidents with adulterated products.
Medicinal Qualities
E. Ginseng root (Ginseng radix) has been an approved herb since 1991 by The Complete German Commission E Monographs (B. ANZ. No. 11). 16 The United States Pharmacopoeia/National Formulary published a monograph and compendial standard for Ginseng (in the Ninth Supplement to the USP 23NF 18) as p.r. of it’s Botanical monograph series. (Note: the USP was established in 1820 to create standards for the use and quality of pharmaceuticals and combined with the National Formulary in 1980). 18,19
Throughout the ages 15 medicinal and magical qualities ascribed to Panax acted as a tonic, maintaining a healthy body, rejuvenating and prolonging life and acting as a sexual enhancer balancing "Yin" and "Yang".
There is large amount of good research currently being done on Panax ginseng and it’s medicinal effects. Since the 1990s differentiation and research on the various varieties of Panax is also being reported and the use of advanced techniques of layer, gas and high performance liquid chromatography have enabled efficient separation and isolation techniques allowing accurate research and development of Ginseng products. 20,21,22
Ginseng has been listed by some as useful in the treatment of diabetes, anemia, cancer, depression, insomnia, shock, fatigue, hypertension, effects of radiation, effects of morphine and cocaine use, environmental, physical and mental stress, and chronic illness. It has been said to act as a stimulant, promote endurance, increase life expectancy, relax the nervous system, improve mental awareness, encourage proper hormonal functions, improve lipid levels, lower cholesterol, improve nerve growth, and increase resistance to disease. It is said to act as an antioxidant, autoimmune stimulant, psychotropic and have anti-tumor actions 23 (see Pharmacology and Clinical Studies).
Research has shown that Ginseng may have the ability to act as an "adaptogen", prolonging life by combating viral infections and Pseudomonas aeruginosa. Research continues to support ginseng’s protective role against anti-cancer treatments and drugs, perhaps even countering the side effects of chemotherapy. There is some thought that Ginseng may be useful "clinically for the prevention of abuse and dependence of opioids and psychostimulants." 137
Panax ginseng is still a main staple in Chinese medicine. "There have been more than 300 original papers (written) in Chinese and in English during the last 10 years in China" 22 as well as studies in Europe and America that may support this usage. Though some subjects s.c. as "Quality of Life" remain controversial due to the inability to measure accurately an intangible term, there is no doubt that ginseng has therapeutic qualities. 23
Taste: Sweetish, bitter, can be licorice-like
Parts utilized: Root – fresh or dried; leaf (all of the plant can be used, however the root is the most highly regarded for it’s medicinal effects)

Biochemical Constituents Studies:
"The dried roots and rhizomes of ginseng (P. ginseng C. A. Meyer) contain many physiologically important constituents s.c. as ginseng saponins, ginseng oils and phytosterol, carbohydrates and sugars, organic acids, nitrogenous substances, amino acids and peptides, vitamins and minerals, and certain enzymes that have been isolated and characterized. Among these, ginseng saponins are proven to be the principal and most active constituents. So far 13 saponins have been isolated and identified and these, which have been called ginsenosides or panaxosides, are triterpenes of dammarane and oleanane structures." 39,41,43 Also, compound K (C-K), is a major metabolite of ginsenoside Rb1 (G-Rb1) from Panax ginseng root …" 30. "Germanium is believed to be abundant, but little toxic, in natural drugs s.c. as ginseng." 31
"Ginseng root, a traditional oriental medicine, contains more than a dozen biologically active saponins called ginsenosides, including one present in only trace amounts called ginsenoside-Rf ." 29 Ginsenosides (Rf, Rh3, Rh4, R1, R2, Rbl, -Rb2, -Rd, Rg2, Rg4) have been isolated and quantified in several studies. 25,27,32,33,37,38,42,50
It has been found that "ginsenosides are therapeutic dammarane-type oligoglycosides isolated from the water-soluble portion of the dried roots and leaves of Panax ginseng C. A. Meyer (Araliaceae)" 28. A study of dammarane oligopeptides from ginseng isolated a new biologically active peptide which exhibits somnogenic effect 26.
The ginsenoside composition of the main root, lateral root, rhizome, leaves and seeds of Panax ginseng cultivated in Jilin, China was studied. Total saponin content showed a mid-range value as compared to those in ginsengs reported in literature. A high percentage of Rg1 in the main root of fresh and sun-dried specimens from the same batch "might account for the traditional preference of this plant p.r. despite its lowest percentage of saponin in the whole plant." 40
Tests have found 17 amino acids, which reach their peak point during sprouting period in April. 24
Polysaccharides from the root of ginseng have shown considerable dose-dependendent immunological, phagocytic, and anti-complement activities in several studies. 34, 35,36
Above Ground Parts:
Numerous studies have shown that polysaccharides found in the leaves of the Panax ginseng have immunological, anti-ulcer and anti-complement activities. 44, 45, 48, 49
In studies isolation and identification of compounds from the fruit of cultivated Panax ginseng was made "on the basis of physicochemical constants and spectral evidences." 46, 47
