Antihyperlipidemic and antihyperglycemic effects of Red Ginseng (RG, steamed and dried root of Panax ginseng C.A.Meyer, family Araliaceae), major component of which is ginsenoside Rg3, and Bifidodoterium-fermented RG (FRG), major component of which is ginsenoside Rh2, were investigated. Orally administered RG and FRG potently reduced the serum triglyceride levels in com-oil-induced hypertriglycemidemic mice as well as total cholesterol and triglyceride levels in Triton WR-1339-induced hyperlipidemic mice. Of the saponin and polysaccharide fractions of RG and FRG, the polysaccharide fraction inhibited postprandial blood glucose elevation of maltose- or starch-loaded mice and reduced the blood triglyceride levels in com-oil-induced hypertriglycemidemic mice. The saponin fraction and its ginsenosides Rg3 and Rh2 reduced blood triglyceride and total cholesterol levels in Triton WR1339-induced hyperlipidemic mice. The inhibitory effect of FRG and its main constituents against hyperlipidemia and hyperglycemia in mice were more potent than those of RG. These findings suggest that hypolipidemic and hypoglycemic effects of RG can be enforced by Bifidus fermentation and FRG may improve hyperlipidemia and hyperglycemia.

Background: Ginseng (Panax ginseng Meyer) is an important medicinal herbs in Asia. However, ginseng varieties are less developed. Method: To developed ginseng varieties, a pure line selection method was applied in this study. Results: Gumpoong was testing of 4-yr-old specimens in 2002, the proportions of the below-ground roots that were rusty colored for Gumpoong was 1.29 in Daejeon and 1.45 in Eumseong, whereas the proportions for its yellow berry variant were 2.60 and 2.45 in the two regions, respectively. Thus the Gumpoong was resistant to root rust. Sunpoong has a high yielding property. Its average root weight is 70.6 g for 6-yr-old roots. Its yield is 2.9 kg/$1.62m^2$ and the rate of heaven- and earth-grade product is 20.9%, which is very high compared to 9.4% for Yunpoong. Sunone is resistance to root rot and the survival rate of 4-yr-old roots was 44.4% in 1997, whereas that of the violet-stem variant landrace was 21.7%. Sunhyang has content of arginyl-fructosyl-glucose (AFG), which produces the unique scent of red ginseng, is $95.1{\mu}mol/g$ and greater than the $30.8{\mu}mol/g$ of Chunpoong in 6-yr-old plants. Sunun and Cheongsun are being nurtured to protect genetic resources. Conclusion: Developed ginsneg varieties will be used as the basis for the protection of genetic resources and breeding.

Ginseng is being distributed in 35 countries around the world and there are differences by each country in the distribution volume and amount. However, since there is no accurate statistics on production and distribution amount by each country, it is very difficult to predict the world ginseng market. Ginseng trading companies and governments are in desperate need of comprehensive data that shows the world ginseng market status for sales and marketing. For that reason, this study will look into the approximate size of the world ginseng market based on recent ginseng distribution amount by each country and production by major ginseng producing nations. In addition, the review sets an opportunity to check the status of ginseng (Korea) in the world and presents future direction by examining recent history of ginseng development in Korea, which is one of the world's largest ginseng distributers. Since ginseng is cultivated in limited areas due to its growth characteristics, ginseng distributing countries can be divided based on whether they grow it domestically or not. In general, four countries including South Korea, China, Canada, and the US are the biggest producers and their total production of fresh ginseng is approximately 79,769 tons which is more than 99% of 80,080 tons, the total ginseng production around the world. Ginseng is distributed to different countries in various forms such as fresh ginseng, dried ginseng, boiled and dried ginseng (Taekuksam), red ginseng and the related products, etc. and is consumed as food, dietary supplements, functional food, medical supplies, etc. Also, the world ginseng market including ginseng root and the processed products, is estimated to be worth $2,084 million. In particular, the size of the Korean market is $1,140 million which makes Korea the largest distributer in the world. Since the interests in alternative medicine and healthy food is increasing globally, the consumer market of ginseng with many features and the processed products are expected to expand continuously.

Background: During the aging process, skin shows visible changes, characterized by a loss of elasticity and the appearance of wrinkles due to reduced collagen production and decreased elasticity of elastin fibers. Panax ginseng Meyer has been used as a traditional medicine for various diseases due to its wide range of biological activities including skin protective effects. Ginsenosides are the main components responsible for the biological activities of ginseng. However, the protective activities of an enzymatic preparation of red ginseng against human skin aging have not been investigated. Methods: The efficacy of an enzyme-treated powder complex of red ginseng (BG11001) in preventing human skin aging was evaluated by oral administration to 78 randomized individuals. All patients were requested to take three daily capsules containing either 750 mg of BG11001 or a placebo vehicle for 24 wk; at the end of the testing period, skin roughness, elasticity, and skin water content were measured. Results: BG11001 significantly reduced the average roughness of eye wrinkles and the Global Photo Damage Score compared with the placebo, although there were no significant differences in arithmetic roughness average between the groups. In addition, gross elasticity and net elasticity values increased, and transepidermal water loss level decreased, indicating improved skin elasticity and moisture content. Conclusion: In conclusion, enzyme-treated red ginseng extract significantly improved eye wrinkle roughness, skin elasticity, and moisture content. Moreover, enzyme-treated red ginseng extract would be useful substance as a bio-health skin care product.

We previously reported that in vitro anti-platelet activity of tissue-cultured mountain ginseng (TCMG) ethanol extracts show improved efficacy when compared with commercial ginseng products such as Korean red ginseng and Panax ginseng. However, information on the anti-platelet activity of the ethyl acetate fraction from TCMG adventitious roots is limited. Therefore, in this study, we further investigated the effects of an ethyl acetate extract of TCMG (EA-TCMG) adventitious roots on in vitro antiplatelet activity in whole human blood and its effect on peripheral blood flow in mice. We found that EA-TCMG inhibited platelet aggregation with $IC_{50}$ values of 271, 180, and 147 ${\mu}g$/mL induced by collagen, adenosine-5'-diphosphate, and arachidonic acid, respectively. Among the three agonists used, thromboxane $A_2$ formation induced by arachidonic acid was markedly suppressed. Furthermore, EA-TCMG improved the peripheral circulatory disturbance by improving vascular blood flow. In conclusion, these results suggest that ethyl acetate extracts from TCMG adventitious roots might inhibit vascular platelet aggregation and thrombus formation.

Fresh Panax gineng C.A. cultivated in Korea(Korean red ginseng) was found to be ineffective as anticarcinogenic or cancer preventive in experimental animal model or in human case-control and cohort study. However, when treated with heat, the fresh ginseng, white ginseng were highly effective cancer preventives. Four compounds including 20(S)-ginsenoside Rh$_1$(Rh$_1$), 20(S)-ginsenoside Rh$_2$(Rh$_2$), 20(S)0-siwenoside Rg$_3$(Rg$_3$) and sinsenoside Rg$\sub$5/ were consequently purified from Korean red ginseng, and they were tested by Yun\`s 9 week medium-term anticarcinogenicity test model. Rg$_3$ and Rg$\sub$5/ statistically significantlydecreased the incidence of benzo(a)pyrene-induced mouse lung tumor, Rh$_2$showed tendency of decrease, and Rh1 showed no effect. It is, therefore, concluded that Rg$_3$ and Rg$\sub$5/ are active anticarcinogenic components in res ginseng and they either singularly or synergistically act in the prevention of cancer.

Ginseng was the most revered of the herbs in ancient times in China, Korea, Japan, America. Ginseng was discovered over 5000 years ago in the mountains of Manchuria, China. References to ginseng are found in books dating back more than two millennia. It is revered by the Chinese people as it is considered a herb for everything use and therefore for a wide range of diseases (currently its Latin name derived from the Greek panacea, meanings, that is, for everything). So, it was used exclusively by the Chinese Emperor's, and they were willing to pay the price without problems. Increasing its fame, ginseng brought a flourishing international trade that allowed Korea to supply China with silk and medicines in exchange for wild ginseng and later along with what grows in America.

We reported previously that the administration of Korean red ginseng water extract (KRG-WE) protected the guinea pig testis against damage induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (a potent endocrine disruptor). We also found that crude saponin from ginseng was the active ingredient responsible for this protection. Here, we examined the biological role of KRG-WE in an animal model of age-induced dysfunction of spermatogenesis. Twenty-four male Sprague-Dawley (six 2-month-old and eighteen 12-month-old) rats were used. The young and old control groups received only vehicle. The ginseng saponin (GS)- and KRG-WE-treated groups received GS (40 mg/kg body weight/day) and KRG-WE (200 mg/kg body weight/day), respectively, for 4 months. The number of cells, Sertoli cell index, Johnsen's score, and sex hormone levels decreased significantly with age. However, the administration of KRG-WE and GS markedly improved the number of germ cells, seminiferous tubular size, and Johnsen's score in the old rats. Ginseng produced a distinct testicular histological improvement in old rats. KRG-WE and GS elevated testosterone levels, while attenuating the aberrant increase in follicle stimulating hormone and luteinizing hormone levels. Sperm kinematics evaluated by a computer-assisted sperm analyzer demonstrated improvement in the percentage of motile sperm, progressive sperm motility, and curvilinear velocity associated with sperm quality, supporting the beneficial role of red ginseng in senile spermatogenesis. Overall, the total water extract had a more potent effect than the corresponding saponin fraction. In conclusion, Korean red ginseng rejuvenated age-induced testicular dysfunction. Additionally, the total water extract was more potent than the corresponding saponin fraction.

This study was conducted to investigate the characteristics of aboveground plants and red ginseng of polystem ginseng in 6 years of age having two or more stems in a plant. Total leaf weight and area of polystem ginseng were larger, while its stem diameter, and the leaf weight and area of the big­gest stem in each plant were decreased with increase the stem numbers in a plant. The ratio of shoot weight to root weight in the polystem ginseng with three or more stems was higher than that in the monos­tem ginseng and the polystem ginseng with two stems, In ginseng plants with no more than 2 stems, there were positive correlations between root weight and total leaf weight, and leaf area, but not between leaf weight and area of the biggest stem. Inner cavity and inner white, limiting factors for redginseng quality grade, occurred more in tri-stem ginseng than mono- and di-stem one. Percentages of Heaven (1st grade) and Earth (2nd grade) red ginseng in tri-stem ginseng were decreased compared with mono stem and di-stem ginseng.
