American Ginseng Extract Panax quinquefolius L.
American Ginseng is a species of ginseng that grows wild in North America. In the 18th century, wild ginseng was discovered in North America, and was called, not surprisingly, “American ginseng.” Since then, many ginseng farms have sprouted up, though it is still possible to find wild American ginseng. The state of Wisconsin is the capital of American ginseng. American ginseng is used as a energy booster and to improve circulation as well as strengthen immune system. It works on the spleens and lungs The spleen assimilates external energy and transforms it into internal energy. The lungs govern the body’s physiological energy and distributes around the body. Even if you are not ill, ginseng can help increase your vitality, improve your energy level and promote general good health. The major difference between panax red ginseng and American ginseng is its potency. American ginseng has a milder qi boosting effect and so is suitable for people of all ages and conditions. American ginseng is mainly used for clearing the body’s inner heat and tonifying the qi. Our bodies accumulate inner heat when we consume too much fried or spicy foods, don’t get enough sleep, or during the hot summer months. American ginseng is good for gently boosting your energy level and for helping to overcome the irritability that comes from lack of sleep, or to help the acne resulting from too much fried foods.

American ginseng, Panax quinquefolius L. [Fam. Araliaceae], is closely related to Asian ginseng, Panax ginseng C. A. Meyer, and has many medicinal virtues. The genus name Panax is derived from the Greek words pan (all) and akos (cure) meaning cure-all. Panax quinquefolius contains many of the same active ginsenosides as Panax ginseng. According to Dr. James Duke in the book, The Green Pharmacy, America exports close to $100 million worth of American ginseng annually, mostly to Asians who regard it as an herbal fountain of youth. Controlled studies of Asian ginsengs have repeatedly found improvements in exercise performance (including muscular strength, maximal oxygen uptake, work capacity, serum lactate, heart rate, visual and auditory reaction times, alertness, and psychomotor skills) with a daily dosage greater than 1g of dried root (or equivalent) when taken for at least 8 weeks, particularly with older subjects. Most clinical studies on American ginseng relate to its property of reducing hyperglycemia in normal and hyperglycemic persons. A preliminary short-term clinical study involving 10 normal subjects and 9 blood-sugar control patients randomized to receive 3g ginseng or placebo was conducted to assess whether American ginseng affects after-meal glycemia in humans. The ginseng (or placebo) was given 40 minutes before or together with a 25g oral glucose challenge. In normal subjects, ginseng taken 40 minutes before the glucose challenge significantly reduced after-meal glycemia. In subjects with blood-sugar control problems, the same was true whether capsules were taken before or together with the glucose challenge. The researchers concluded that American ginseng attenuated after-meal glycemia in both study groups. American ginseng also combats stress, boosts the immune system, provides antioxidants to fight chronic disease and aging and prevents endothelial cell damage considered to be the initial step in the genesis of thrombosis and artery damage, the precursors of vascular disease.
Standardized extracts of American ginseng root contain: 4-5% ginsenosides. The Swiss Pharmacopoeia requires ginseng roots to contain at least 2% ginsenosides while the German standard license requires only 1.5% or more.Triterpene saponins known as ginsenosides ?at least 31 different ones have been identified ?including 7 ginsenosides used as marker compounds for Panax species, which include Asian and American ginseng; Sesquiterpenes; Polyacetylenes And Polysaccharides; Panax Quinquefolius Contains: Acetic Acid; Adenine; Adenosine; Alanine; Alloisoleucine; Aluminum; Alpha-Aminobutyric Acid; Beta-Aminoisobutyric; Beta-Aminobutyric Acid; Amylase; Arabinofuranose; Arabinose; Arasaponin A And B; 1.2-1.76% Arginine; 0.1-0.4% Aspartic Acid; Bicyclogermacrene; Biotin; Boron; Calcium; Campestrol; Approximately 70% Carbohydrates; Caryophyllene; 0.1-0.2 Choline; 0.3% Citric Acid; Escin; Estradiol; Estrol Estrone; 1.0% Fat; 5.9-24.5% Fiber; 0.4-0.5% D-Fructose; Ginsenin; Ginsenosides Ro, Rb, Rb1, Rb2, Rc, Rd, Re, Rf, Rg 1 And 2; 0.5-1.5% D-Glucose; Glutamic Acid; Glycine; Histidine; Alpha And Beta-Humulene; Iron; Isoleucine; Kaempferol; Ketoglutaric Acid; Leucine; Linoleic Acid; Linolenic Acid; Lysine; 0.1-0.2% Magnesium; Maltose; 1.5-2% Nitrogen; Oleanolic Acid; Oleic Acid; 0.6-0.9% Panaxadiol; 0.7-1.2% Panaxatriol; Panaxoside A-F; Phosphorus; 0.6-3.4% Potassium; 12.2% Protein; 0.7% Pyruvic Acid; Resin; 0.75-1% Saponin; Alpha, Beta And Gamma-Selinene; Beta-Sitosterol; 0.05-0.48% Sodium; 8-32% Starch; 0.05% Stigmasterol; 4.0% Succinic Acid; 1.5-8.5% Sucrose; 0.15% Sulfur; Tannin; 0.05-0.1% Threonine; Tiglic Acid; Uracil; Uronic Acid; N-Valeric Acid; Valine; Vanadium; Vitamin B-12; Zinc [Information on American ginseng root taken from: Duke JA. 1992.
