Ginseng root

Latin Name: Panax ginseng
Pharmacopeial Name: Ginseng radix
Other Names: Asian Ginseng, Chinese ginseng, Korean ginseng, true ginseng


Ginseng is a slow-growing perennial herb native tothe mountain forests of northeastern China, Korea, and the far eastern regions of the Russian Federation. In China, the natural range for ginseng extends from Hebei Province to the three northeastern provinces of Liaoning, Jilin, and Heilongjiang. It is cultivated extensivelyin China, Japan, Korea, and Russia. The Changbai mountain range is reportedly the only area in China where wild ginseng still occurs naturally(Bone, 1998; Foster and Chongxi, 1992; Leung and Foster, 1996; Melisch et al., 1997; Wichtl and Bisset, 1994).It usually starts flowering at its fourth year and the roots take four to six years to reach maturity. "White" ginseng root (unprocessed) is sometimes bleached and then dried and "red" ginseng is prepared from white ginseng by various processing methods, such as steaming the fresh root before drying. There are many types and grades of ginseng, depending on the origin, root maturity, parts of the root used, and methods of raw material preparation or processing (Bradley, 1992; Foster and Chongxi, 1992; Leung and Foster, 1996). In Russia, Panax ginseng comes mostly from cultivation and partly from permitted or illegal harvest in the wild. Wild ginseng is listed under protected status in the Russian Red Data Book and, therefore, its harvest and trade is prohibited under Russian law. Under China's nationally protected species schedule, ginseng is subject to the Protection Category 1, comparable to its status in the Russian Federation (Melisch et al., 1997). In China, North and South Korea, and Japan, P. ginseng comes from cultivated sources (Yen, 1992).

Ginseng's genus name Panax is derived from the Greek pan (all) akos (cure), meaning cure-all. The transliteration of the word gin (man) seng (essence) is derived from the Chinese ideogram for "crystallization of the essence of the earth in the form of a man" (Foster, 1991; Hu, 1976). Ginseng's therapeutic uses were recorded in the oldest comprehensive materia medica, Shen Nong Ben Cao Jing, written around two thousand years ago. In Asian medicine, dried ginsengis used as a tonic to revitalize and replenish vital energy (qi). The usual effect of replenishing qi is not to give an energy boost like that of caffeine or amphetamine (Dharmananda, 1999). It is traditionally used as an aid during convalescence and as a prophylactic to build resistance, reduce susceptibility to illness, and promote health and longevity. Its activity appears to be based on whole body effects, rather than particular organs or systems, which lends support to the traditional view that ginseng is a tonic that can revitalize the functioning of the organism as a whole. There is no equivalent concept or treatment in Western conventional medicine. However, multivitamins are used in a similar manner. In traditional Chinese medicine it is usually prescribed in combination with other herbs and taken in an aqueous decoctiondosage form(Bone, 1998; Foster and Chongxi, 1992; Leung and Foster, 1996; Wichtl and Bisset, 1994).Today, ginseng is official in the national pharmacopeias ofAustria, China, France, Germany, Japan, Switzerland, and Russia(Bradley, 1992; DAB 10, 1994; JP XII, 1993; AB, 1981; Ph.Fr.X, 1990; Ph.Helv.VII, 1987; Tu, 1992; USSR X, 1973; Wichtl and Bisset, 1994).The Pharmacopoeia of the People's Republic of China indicates its use for prostration with impending collapse marked by cold limbs and faint pulse; diminished function of the spleen with loss of appetite; diabetes caused by "internal heat""; general weakness with irritability and insomnia in chronic diseases; impotence or frigidity; and heart failure and cardiogenic shock (Tu, 1992).[It should be noted that in traditional Chinese medicine, the term "spleen" does not correlate to the western anatomical definition of spleen but rather to the entire digestive system, with regard to its functions of digestion, transport and distribution of nutrients, blood flow, and reinforcement of vital energy (qi). "Diabetes caused by internal heat" is a specific condition with symptoms including excessive thirst and urination, and sometimes accompanied by excessive eating (Tu, 1992; Yen, 1992).]

In Germany, ginseng is one of a few economically important herbal drugs listed separately in the Foreign Trade Statistics. In 1992, Germany imported 174.6 tons, mainly from China and Hong Kong. A considerable amount of the roots are value-added in Germany and then exported mostly to France, Italy, and Argentina (Lange and Schippmann, 1997).Ginseng is official in the German Pharmacopoeia, approved in the Commission E monographs, and usedin geriatric remedies, roborants (invigorating and strengthening medicines), and tonic preparations. The Commission E specifies powdered root or tea infusions (BAnz, 1998; Bradley, 1992; DAB 10, 1994;Meyer-Buchtela, 1999;Wichtl and Bisset, 1994).In the United States, it is used by itself and as a main ingredient in a wide range of tonic, energy, and immunostimulant dietary supplements. It is also used extensively in traditional Chinese medicine herbal teas and other fluid or solid forms prescribed to patients by licensed acupuncturists and naturopathic physicians.

During the past fifty years, numerous scientific studies of varying quality have been published on ginseng (Foster and Chongxi, 1992). Modern human studies have investigatedits preventive effect on several kinds of cancer (Yun et al., 1993; Yun and Choi, 1995, 1998), its effect on newly diagnosed non-insulin-dependent diabetes mellitus patients (Sotaniemi et al., 1995), its long-term immunological effect on HIV patients (Cho et al., 1994; Cho et al., 1997; Sankary, 1989), its ability to treat "qi-deficiency" and blood-stasis syndrome of coronary heart disease and angina pectoris (Jiang et al., 1992), its ability to treat hepatotoxin-induced liver disease in the elderly (Zuin et al., 1987), its effect on cell-mediated immune functions in healthy volunteers (Scaglione et al., 1990), its ability to induce a higher immune response in vaccination against influenza (Scaglione et al., 1996), its effect on blood pressure in patients with hypertension (Han et al., 1998), its effect on alveolar macrophages from patients suffering with chronic bronchitis (Scaglione et al., 1994), its ability to treat severe chronic respiratory diseases (Gross et al., 1995), its use in the treatment of functional fatigue (Le Gal et al., 1996), its ability to improve quality-of-life in persons subjected to high stress (Caso Marasco et al., 1996), its effect on psychomotor performance in healthy volunteers (D'Angelo et al., 1986), its effect on physical performance during exercise (Pieralisi et al., 1991), its ability to treat erectile dysfunction (Choi et al., 1995), and its ability to treat male infertility (Salvati et al., 1996).

Some clinical trials have suggested the use of ginseng for fatigue and the improvement of physical and mental performance (Dorling and Kirchdorfer, 1980; Forgo et al., 1981). Ginseng has been studied for treatment of cerebrovascular insufficiency (Quiroga and Imbriano, 1979; Quiroga, 1982), psychophysical asthenia and depressive symptoms (Rosenfield, 1989), immunomodulation (Scaglione et al., 1990; Scaglione et al., 1996). Trials have also reported favorable results in treating post-menopausal symptoms (Reinold, 1990) and improving athletic performance (Forgo and Kirchdorfer, 1981, 1982). A review in a popular newsletter has raised questions regarding the design and results of some of these studies (Schardt, 1999). Several recent trials have reported negative results for improvement of performance during aerobic exercise (Allen et al., 1998; Morris et al., 1996; Engels and Wirth, 1997; Cherdrungsi et al., 1995) and in the secondary treatment of geriatric patients (Thommessen and Laake, 1996).

Many of the clinical studies published in the scientific literature have been conducted on a proprietary extract of P. ginseng standardized to 4% total ginsensenosides (G115®, Ginsana®, Pharmaton, Lugano, Switzerland). There have been four studies conducted on G115 to measure the effect of ginseng on endurance and vitality (Dorling and Kirchdorfer, 1980; Forgo et al., 1981; Gross et al., 1995; Sandberg, 1980). Three studies have been conducted on psychoasthenia (Mulz et al., 1990; Rosenfeld, 1989; Gianoli and Riebenfeld, 1984). Ten clinical trials have attempted to determine if ginseng affects physical stress and psychomotor functions (Forgo and Kirchdorfer, 1981; Forgo and Kirchdorfer, 1982; Forgo, 1983; Forgo and Schimert, 1985; Van Schepdael, 1993; Pujol et al., 1996; Engels and Wirth, 1997; Engels et al., 1996; Collomp et al., 1996; D'Angelo et al., 1986). Two clinical trials have investigated cerebral blood flow deficits (Quiroga and Imbriano, 1979; Quiroga, 1982). Two studies on pharmacodynamics measured the immunomodulatory effects (Scaglione et al., 1990; Scaglione et al., 1994), oxygen uptake (von Ardenne and Klemm, 1987), doping substances in urine (Mulz and Degenring, 1989; Forgo, 1980), and serum glucose, serum cholesterol, and serum triglyceride levels (Cheah, 1994).

One double-blind placebo-controlled study investigated the effect of ginseng on newly diagnosed non-insulin-dependent diabetes mellitus (NIDDM) patients (Sotaniemi et al., 1995). Thirty-six NIDDM patients (20 women and 16 men) were recruited in five health centers and were treated for eight weeks. Patients were randomized to ingest one tablet daily containing 0 (placebo), 100, or 200 mg ginseng, presumably an extract, but the authors did not state the type of preparation used in the study (manufactured by Dansk Droge, Copenhagen). Effects on psychophysical tests, measurements of glucose balance, serum lipids, aminoterminalpropeptide (PIINP) concentration, and body weight were tested.Ginseng therapy elevated mood, improved psychophysical performance, and reduced fasting blood glucose (FBG) and body weight. The 200 mg dose of ginseng improved glycated hemoglobin, serum PIINP, and physical activity. The authors concluded that ginseng may be a useful therapeutic adjunct in the management of NIDDM, but because the active material was not adequately identified, it is difficult to draw meaningful conclusions from this study.

To test for possible anticancer effects, one case-controlled study, conducted at the Laboratory of Experimental Pathology at the Korea Cancer Center Hospital with 1,987 pairs of subjects, investigated the preventive effect of ginseng intake against various human cancers (Yun and Choi, 1995). In this study, those participants ingesting ginseng had a decreased risk for cancer compared with non-users. A decrease in risk with increased frequency and duration of ginseng ingestion was reported, showing a dose-response relationship. The preventive effect was reported with the ingestion of fresh undried root extract, white dried root extract, powdered white dried root, and red steamed root. Other ginseng dosage forms tested in this study did not show a decrease in cancer risk including fresh sliced root, fresh root juice, and white root tea. The authors concluded that their findings support the view that patients who take ginseng have a decreased risk for most cancers compared with those who do not.

In a subsequent prospective study the non-organ specific cancer preventive effects of ginseng were investigated in 4,634 people over 40 years old, residing in ginseng production areas, from August, 1987 to December, 1992 (Yun and Choi, 1998). Among ginseng preparations, fresh ginseng extract consumers were associated with a significantly decreased risk of gastric cancer. The authors concluded that their results strongly suggest that ginseng has a non-organ specific preventive effect against cancer, providing support for the previous case-control studies.

The approved modern therapeutic applications for ginseng appear to be generally supportable based on its history of use in well established systems of traditional medicine, extensive phytochemical investigations, pharmacological studies in animals, and human clinical studies. However, recent studies do not support results from earlier research. The World Health Organization (WHO) has issued a monograph reviewing standards and therapeutics of Asian ginseng, concluding that some general uses are warranted by clinical data (see Uses below) (WHO, 1999).

Chinese and Japanese pharmacopeial grade ginseng must be composed of the dried mature root, collected in autumn, from which the rootlets have been removed.Botanical identity must be confirmed by thin-layer chromatography (TLC) as well as by macroscopic and microscopic examinations and organoleptic evaluation. It must contain not less than 14% dilute ethanol-soluble extractive, among other quantitative purity standards (JP XII, 1993; Tu, 1992).The British Herbal Pharmacopoeia requirements are comparable to the Asian monographs with some exceptions, including not less than 20% ethanol-soluble extractive (70%), calculated with reference to the oven-dried material (BHP, 1996). The German Pharmacopoeia requires not less than 1.5% total ginsenosides calculated as ginsenoside Rg1, botanical identification by TLC, macroscopic and microscopic examination, organoleptic evaluation, and some quantitative purity standards (DAB 10, 1994). The Swiss Pharmacopoeia requires not less than 2% total ginsenosides calculated as ginsenoside Rg1 (Ph.Helv.VII, 1987).


Ginseng root consists of the dried main and lateral root and root hairs of P. ginseng C.A. Meyer [Fam. Araliaceae] and their preparations in effective dosage. The root contains at least 1.5% ginsenosides, calculated as ginsenoside Rg1.

Chemistry and Pharmacology

The biologically active constituents in P. ginseng are a complex mixture of triterpene saponins known as ginsenosides (Lewis, 1986; Ng and Yeung, 1986; Liu and Xiao, 1992). The root contains 2–3% ginsenosides of which Rg1, Rc, Rd, Rb1, Rb2, and Rb0 are quantitatively the most important.

At least 30 ginsenosides have been isolated and characterized (Ng and Yeung, 1986). The pharmacological actions of individual ginsenosides may work in opposition. For example, the two main ginsenosides, Rb1 and Rg1, respectively suppress and stimulate the central nervous system (Chong and Oberholzer, 1988). These opposing actions may contribute to the "adaptogenic" description of ginseng and its purported ability to balance bodily functions. Ginseng's pharmacological activities may be multiple and complex, due not only to ginsenosides but to a variety of compounds such as panacene (a peptidoglycan), which has exhibited hypoglycemic activity (Konno et al., 1984), a peptide with insulinomimetic properties (Ando et al., 1980), and salicylate and vanillic acid, which showed antioxidant and antifatigue effects in animals (Han et al., 1983).

The Commission E reported that in various stress models such as immobilization test and coldness test, the resistance of rodents was enhanced. Ginseng is reported to possess hormone-like and cholesterol-lowering effects, promote vasodilatation, and act as an anxiolytic and antidepressant (Choi et al., 1995; Chong and Oberholzer, 1988). Many studies on animals have found ginseng extracts and ginsenosides to be effective in stimulating learning, memory, and physical capabilities (Petkov and Mosharrof, 1987), supporting radioprotection (Takeda et al., 1981; Takeda et al., 1982), providing resistance to infection (Singh et al, 1984), demonstrating antioxidant and antifatigue effects (Han et al., 1983; Saito et al., 1974), enhancing energy metabolism (Avakian et al., 1984), and reducing plasma total cholesterol and triglycerides while elevating HDL levels (Yamamoto et al., 1983). A recent study at Yale University has suggested that ginseng's vasodilatory action may be due to nitric oxide synthesis (Gillis, 1997).


The Commission E approved ginseng as a tonic for invigoration and fortification in times of fatigue and debility or declining capacity for work and concentration. Ginseng was also approved for use during convalescence.

The World Health Organization (WHO) monograph section on 'uses supported by clinical data' re-affirms the Commission E approved uses: ' used as a prophylactic and restorative agent for enhancement of mental and physical capacities, in cases of weakness, exhaustion, tiredness, and loss of concentration, and during convalescence' (WHO, 1999).


Hypertension (Bradley, 1992).

Side Effects

None known.

Use During Pregnancy and Lactation

The Commission E reports no known restrictions on the use of ginseng during pregnancy and lactation. Although the British Herbal Compendium contraindicates ginseng during pregnancy, this is not substantiated by use in Asia or by the Commission E (McGuffin et al., 1997). However, controlled, long-term safety studies have not been conducted. WHO has also reiterated that the safety of ginseng use during pregnancy has not been established, although it noted that ginseng is not teratogenic (WHO, 1999).

Interactions with Other Drugs

The British Herbal Compendium contraindicates the use of ginseng with stimulants, including excessive use of caffeine (Bradley, 1992). The WHO monograph cites two cases of ginseng interaction with phenelzine, a monoamine oxidase inhibitor, although the clinical significance of this interaction was yet to be determined (WHO, 1999).
