With microorganism as a single cell model to investigate the cellular effect of total extract of ginseng powder, it was found that ginseng affects cellular respiration biphasically (Tso and Fung, 1980; Tso, 1981). As ginseng is recognized to be a tonic medicinal herb, this finding suggests a possible role of ginseng in altering cellular energy metabolism. Along this line, the same effect on mitochondrial oxygen consumption was studied. It was found that under a controlled pH condition, a significant stimulation of the mitochondrial respiration was observed. This stimulation was ginseng dose-dependent. However, when ginseng was applied at an above threshold concentration, an inhibitory effect was noted. This confirms the previous observation with single cell organism and suggests a universal regulation of energy metabolism effect that transcends cell origin.

Objective: A meta-analysis was performed to determine effect of ginseng on blood pressure. Methods: The databases of PubMed, Embase, Cochrane Library, RISS, DBpia, KISS, and Koreamed were searched for all published studies from inception to January 2016. The following terms were used: "ginseng", "hypertension", and "blood pressure". Using the Review Manager 5, mean differences (MDs) were pooled to measure the effect of ginseng on blood pressure compared to that of placebo. Results: Eleven randomized controlled trials were included. In this meta-analysis, ginseng treatment significantly lowered systolic blood pressure (SBP) in a dose-independent way (MD: -1.99, p = 0.04). In subgroup analysis, 8-12 week consumption of ginseng achieved significantly greater reduction in SBP (MD: -3.14, p = 0.03), while single administration of ginseng failed to show BP-lowering effect. When ingested over 8-12 weeks, ginseng significantly lowered diastolic blood pressure (DBP) (MD: -1.96, p = 0.03). No significant association was found between ginseng dose and the magnitude of BP-lowering effect. However, a significant positive relationship was observed between baseline SBP level and the magnitude of SBP reduction (r = 0.848, p = 0.033). Such a relationship was not seen in DBP. Conclusion: Consumption of ginseng for 8-12 weeks achieved significant reductions in SBP and DBP in a dose-independent way. There was a significant positive relationship between baseline SBP level and the magnitude of SBP reduction.

Objective : To build a basis of a research strategy for development of Korean ginseng as a global competitive medical product in the world market by Korean Oriental medicine group. Methods : Survey of all literature or analysis reports about market patterns related to ginseng or ginseng products in Korea and in other countries. Results : Korean ginseng and it products have rapidly decreased in share of the world market since the 1980s, with Korean ginseng occupying just 3% of the Hong Kong ginseng market in 2005. While Korean ginseng has been satisfied with consumption within the large Korean market itself, it now has only 1% of world market share. Conclusion : A systematic strategy is needed to strengthen global competitiveness of Korean ginseng based upon development of novel customer-tailored ginseng products. In addition, experience and science-based research in the Oriental medicine field should be involved in the process.

The purpose of this survey was to understand the attitudes, consumption patterns and preferences of domestic consumers relating to ginseng products in general. This study involved 1,305 people (420 agents, 742 ginseng farmer, 143 staff of Korea Tobacco and Ginseng Co.). The results obtained are summerized as follows. 1, Preferences for ginseng were very high for the majority of the respondents. 2. Most (80%) of the respondents had experience in taking ginseng. They expected ginseng to have efficacy as remidy for the hang-over syndrome, gastronil troubles and high blood pressure, in that order. 3. The patron of ginseng were, for the most part, men in the prime of manhood and old age. The favored products and the preferences regarding the organic condition of the ginseng products differed by sex and age. 4 To sum up the results of this study, we conclude that moderate priced ginseng products, not only easy to use and carry but also attractive to age and sex, should be developed without losing the efficacious components and characteristics.

In order to compare the ginseng consumption culture of Korean and Chinese college students, their purchase status of ginseng products, attitudes toward ginseng, and satisfaction with ginseng products were examined, and the purchase and recommendation intention of ginseng products was investigated. It targeted 267 Korean college students and 318 Chinese college students who had experience eating ginseng products. As a result of the survey, in the case of Korean college student consumers, interest in ginseng products increased compared to before COVID-19, and the intention to purchase and recommend ginseng products increased. In addition, the higher the satisfaction with ginseng, the higher the frequency of ginseng purchase experience, the higher the social benefit attitude toward ginseng, and the higher the age, the higher the intention to purchase and recommend ginseng products. Chinese college student consumers had higher parental purchases than Korea, higher positive intentions to purchase and recommend social and psychological benefits, and their 20s are already more interested and friendly than Korea. What Korean college students and Chinese college student consumers have in common is that interest in health, safety, and environment has increased since before COVID-19, and interest in ginseng-related products has changed in individual experiences, indicating that individual experiences are important and Chinese college student consumers are influenced by parents. In particular, COVID-19 is an opportunity to recognize the importance of health, which is important to those in their 20s, and is actually related to purchase intention. Focusing on these results, it seems that expansion to preferred products for college student consumers and differentiation of marketing strategies according to family influence and consumption culture should be made, and these new changes due to COVID-19 seem to be a timely opportunity. At a time when interest in health and safety has increased, strategic preparations are needed for the future consumersociety to respond to changesin product diversity and convergence, changes in marketing media to meet consumer consumption values, and changesin consumer family types, such assingle households.

Attempts were made if diol and triol fractions of ginseng saponin affect on glutamine transport into rat renal cortical mitochondria, swelling, phosphate dependent glutaminase activity, and consumption of oxygen. The following results were obtained. When mitochondrial preparation from rat renal cortex was incubated in medium containing 14C-glutamine and either triol or diol fractions, radioactivity was shown to increase at both 10-6% and 10-5% triol fractions of ginseng saponin, but reduce in case of diol fraction. The remarkable acceleration of the rate of swelling of renal cortical mitochondria was observed in the presence of 10-1% trios and diol fractions but no accerelation at lower concentrations. The activity of phosphate dependent glutaminase from renal cortical mitochondria was slightly activated at 10-2% of triol fraction. However, there was no effect in case of diol fraction. Oxygen consumption by mitochondria from renal cortex was remarkably increased at concentrations of 10-5% and 10-6% triol fractions, but reduced in the case of diol fractions. On the basis of these observations it was concluded that triol fraction of ginseng saponin might increase the transport of glutamine into mitochondria by accelerating the respiratory chain and supplying additional energy to mitochondria, and physiological role of triol fraction was entirely different from that of diol fraction of ginseng saponin.

Korean ginseng products have been fumigated with ethylene oxide (EO) for sterilization and prolongation of storage periods. However, there had been controversies indicating that the consumption of food treated with EO might cause harmful effects in human. Since, in Korea the use of EO gas for food treatment was banned in 1991. Since then, irradiation technique has been developed as an alternative. This study was carried out to investigate the effects of irradiated ginseng on fertility, and reproductive and developmental toxicity. Either EO gas fumigated or gamma-irradiated ginseng was administered to male rats by oral gavage for 63 days during the premating period. Female rats were administered from 14 days before mating to day 20 of gestation or to day 21 of lactation. The exposure amount of irradiation used was 5, 10 and 30 kGy, respectively. There were no treatment related changes of darns in clinical signs, and parturition. No treatment related changes in food consumption, body/organ weights, male/female reproductive and fertility performances were observed. F1 fetuses showed no external abnormality. Reflex/sensory junctions, physical/behavioral development, and reproductive performance of F1 rats were not adversary affected. The results of this study show that gamma-irradiated ginseng, up to 30 kGy, has no adverse effects on the fertility, reproduction and development in Wistar rats.

However, there had been controversies indicating that consumption of EO treated foods might cause harmful effects in human. In Korea, the use EO gas for sterilization of food was banned in 1991. Since then, irradiation technique has been developed as an alternative. This study was carried out to evaluate the safety of irradiated ginseng on peri- and postnatal developmental toxicity in rats. Either EO gas fumigated or gamma-irradiated ginseng was administered to pregnant Wistar rats by oral gavage from gestational day 16 to postnatal day 21. The amount of irradiation used in this study was 5, 10 and 30 kGy, respectively. There were no treatment related changes of dams in deaths, clinical signs, and parturition. No treatment related changes in food consumption, body/organ weight and lactation of dams were observed. Also, no F1 fetuses in external abnormality, physical development, reflex/sensory junctions and behavioral development were found. The results of this study showed that gamma-irradiated ginseng, up to 30 kGy, has no adverse effects on the peri- and postnatal development of rats.

This mass balance study about ginsenoside Rg1 and Re in Red ginseng processed from Fresh ginseng is useful to understand that herbal material sources of ginseng and raw material consumption in Red ginseng preparations. In our results, total molar amounts of ginsenoside Rg1, Re and their converts in Fresh ginseng, Red ginseng, and Red ginseng extract are substantially the same. The molar amounts of ginsenoside Rg1, Re (4.324, 2.880 μmol/g) as starting materials in Fresh ginseng are kept constant as total molar amounts (sum of starting and converts) in Red ginseng (4.264, 2.596 μmol/g) and Red ginseng extract (3.389, 3.129 μmol/g). This result means that protopanaxtriol type ginsenosides and their characteristic converts are not destroyed or inflowing in Red ginseng process. Therefore, it is important for quality assurance of Red ginseng preparations that the ratio between ginsenosides Rg1, Re and these converts is kept constant.
