Korean Ginseng Berry
Extract Effect on Sexual Function in ED - Medscape, 5/6/13 -
"were administered 4 tablets of either standardized
Korean ginseng berry (SKGB, 350 mg ginseng berry extract per tablet), or
placebo, daily, for 8 weeks. Efficacy was assessed with the International
Index of Erectile Function (IIEF)-15 and premature ejaculation diagnostic
tool (PEDT) at the end of the 4th and 8th week. We observed that the total
and each of the individual domain scores of IIEF-15 increased from
40.95+/-7.05 to 46.19+/-12.69 significantly in the SKGB by the 8th week
(P<0.05). The erectile function domain of IIEF changed slightly from
17.17+/-2.57 to 18.59+/-5.99 in the SKGB group by the 8th week (P<0.05). In
addition, PEDT scores significantly improved from 9.14+/-4.57 to 7.97+/-4.4
and 7.53+/-4.26 in the SKGB group after 4 and 8 weeks of treatment (P<0.05).
Safety markers including hormone and lipid in the blood were assessed at the

Protects Hematopoietic Stem Cells against G-CSF-Induced DNA Damage - Cancer
Prev Res (Phila). 2014 Mar 10 - "Granulocyte
colony-stimulating factor (G-CSF) has been utilized to treat neutropenia in
various clinical settings. Although clearly beneficial, there are concerns that
the chronic use of G-CSF in certain conditions increases the risk of
myelodysplastic syndrome (MDS) and/or acute myeloid leukemia (AML). The most
striking example is in severe congenital neutropenia (SCN). SCN patients develop
MDS/AML at a high rate that is directly correlated to the cumulative lifetime
dosage of G-CSF. MDS and AML that arise in these settings are commonly
associated with chromosomal deletions. We have demonstrated in this study that
chronic G-CSF treatment in mice results in expansion of the hematopoietic stem
cell population. In addition, primitive hematopoietic progenitors from
G-CSF-treated mice show evidence of DNA damage as demonstrated by an increase in
double strand breaks and recurrent chromosomal deletions. Concurrent treatment
with genistein, a natural soy isoflavone, limits DNA damage in this population
... The protective effect of genistein was accomplished with plasma levels that
are attainable through dietary supplementation" - See

forced swimming test and a tail suspension test on day 20 and day 21,
respectively, and were sacrificed on day 22. Results of Experiment 1 revealed
that GTS (50 and 25 mg kg(-1) d(-1)) exhibited antidepressant activity and not
statistically altered hippocampal protein levels of brain-derived neurotrophic

Immunomodulatory Activity of Red Ginseng against Influenza A Virus Infection
- Nutrients. 2014 Jan 27;6(2):517-29 - "We investigated
whether red ginseng extract (RGE) has preventive effects on influenza A virus
infection in vivo and in vitro. RGE was found to improve survival of human lung
epithelial cells upon influenza virus infection. Also, RGE treatment reduced the
expression of pro-inflammatory genes (IL-6, IL-8) probably in part through
interference with the formation of reactive oxygen species by influenza A virus
infection. Long-term oral administration of mice with RGE showed multiple
immunomodulatory effects such as stimulating antiviral cytokine IFN-γ production
after influenza A virus infection. In addition, RGE administration in mice
inhibited the infiltration of inflammatory cells into the bronchial lumens.
Therefore, RGE might have the potential beneficial effects on preventing
influenza A virus infections via its multiple immunomodulatory functions"
Rg3 Up-regulates the Expression of Vascular Endothelial Growth Factor in Human

Immunohistochemical analysis showed that expression of VEGF was significantly
up-regulated by Rg3 in a dose-dependent manner in human DP cells and in mouse
hair follicles. In addition, the CD8 and CD34 were also up-regulated by Rg3 in
the mouse hair follicles. It may be concluded that Rg3 might increase hair

Ginsenoside Rg1 Supplementation Improves Age-Related Cognitive Decline by
Promoting Synaptic Plasticity Associated Protein Expression in C57BL/6J Mice
- J Gerontol A Biol Sci Med Sci. 2013 Jul 5 - "In aging
individuals, age-related cognitive decline is the most common cause of memory
impairment. Among the remedies, ginsenoside Rg1, a major active component of
ginseng, is often recommended for its antiaging effects ... This study employed
a scheme of Rg1 supplementation for female C57BL/6J mice, which started at the
age of 12 months and ended at 24 months, to investigate the effects of Rg1
supplementation on the cognitive performance. We found that Rg1 supplementation
improved the performance of aged mice in behavior test and significantly
upregulated the expression of synaptic plasticity-associated proteins in
hippocampus, including synaptophysin, N-methyl-d-aspartate receptor subunit 1,
postsynaptic density-95, and calcium/calmodulin-dependent protein kinase II
alpha, via promoting mammalian target of rapamycin pathway activation. These

Prevention and Immuno-Enhancement Mediated by Daily Consumption of a Proprietary
Extract from North American Ginseng by Elderly Mice of a Cancer-Prone Strain
- Phytother Res. 2012 Nov 7 - "We have previously shown
in a leukemia-induced tumor model (mouse) that a proprietary extract (CVT-E002),
of North American ginseng, administered in the diet, significantly increased the
absolute numbers of NK cells, significantly decreased leukemia cells and
significantly increased the life span of CVT-E002-fed leukemic mice. In the
present study, we assessed the efficacy of this extract to inhibit the
spontaneous development of tumors in elderly mice of the cancer-prone C3H
strain. Dietary CVT-E002 was fed for approximately a year beginning when mice
were almost 2 years of age. Control mice, consuming the same chow without
CVT-E002, all developed assorted, palpable tumors between 22 and 33 months,
while all mice consuming CVT-E002 remained alive and tumor-free until they were
purposely euthanized as healthy animals. The absolute numbers of NK cells at
euthanasia, in CVT-E002-consuming mice, were significantly elevated in both the
spleen and bone marrow. Given these profoundly positive results and the fact
that CVT-E002 already exists in the marketplace under the label Cold-fX®, the

Synergistic Apoptotic Interaction of Panaxadiol and Epigallocatechin Gallate in
Human Colorectal Cancer Cells - Phytother Res. 2012 May 8 -
"Panaxadiol (PD) is a purified sapogenin of ginseng
saponins, which exhibits anticancer activity. Epigallocatechin gallate (EGCG), a
major catechin in green tea, is a strong botanical antioxidant ... Cell growth
was suppressed after treatment with PD (10 and 20 µm) for 48 h. When PD (10 and

antiproliferative effects were observed in both cell lines. Combining 20 µm of
PD with 20 and 30 µm of EGCG significantly decreased S-phase fractions of cells.
In the apoptotic assay, the combination of PD and EGCG significantly increased
the percentage of apoptotic cells compared with PD alone (p < 0.01). The
synergistic apoptotic effects were also supported by docking analysis, which
demonstrated that PD and EGCG bound in two different sites of the annexin V

"Many studies have documented that ginseng has antidiabetic and antiobesity
effects, but the mechanism of the effects has not been elucidated. The aim of
this study was to determine the effect of Korean red ginseng (KRG, Panax

in obese insulin resistant animal models. Sprague-Dawley (SD) rats were divided
into three groups: a control group (group I) fed a normal diet, another group
(group II) fed only high fat diet (HFD) and a third group (group III) fed HFD
with KRG (200 mg/kg, oral) for 18 weeks ... A significant weight reduction,
especially fat mass reduction, was observed in the KRG treated group. Increased
insulin sensitivity was found in the KRG treated group. We observed increased
insulin signalling, increased phosphorylation of IR, IRS-1, Akt, and membranous
GLUT4 in muscle by Western blotting assay. In conclusion, KRG may have
antidiabetic and antiobesity effects due to partly increased insulin sensitivity

Action of Panax ginseng Roots in Hypercortisolism-induced Impairment of
Hippocampal Neurons in Male C57BL/6N Mice - Phytother Res. 2011
Aug;25(8):1242-5 - "An increasing number of people
suffering from hypercortisolism are at risk of developing hippocampus impairment
and mental disorders. The aim of this study was to investigate whether the water
extract of Panax ginseng roots (GWE) could prevent hypercortisolism-induced
adverse consequences. Hypercortisolism was experimentally induced by repeated
corticosterone injection in male mice. Treatment with corticosterone alone
resulted in a significant decrease in hippocampus neurofilament light chain
(NF-L) protein expression and induced depression-like behavior. Serum
corticosterone was significantly increased in the corticosterone-treated mice.
Treatment with GWE (800 and 400 mg/kg) during corticosterone treatment reduced
or partially antagonized the effects induced by corticosterone toward the normal
values of the controls; however, it failed to normalize increased corticosterone
levels in corticosterone-treated mice. Overall, ginseng conclusively exhibited a

Ginseng Rhizome and Ginsenoside Ro on Testosterone 5α-Reductase and Hair
Re-growth in Testosterone-treated Mice - Phytother Res. 2011 May 2 -
"Extracts of red ginseng rhizome showed greater
dose-dependent inhibitory effects against testosterone 5α-reductase (5αR) when
compared with extracts of the main root. Ginsenoside Ro, the predominant
ginsenoside in the rhizome, and ginsenoside Rg(3) , a unique ginsenoside in red
ginseng, showed inhibitory activity against 5αR with IC(50) values of 259.4 and
86.1 µm, respectively. The rhizome of P. japonicus, which contains larger
amounts of ginsenoside Ro, also inhibited 5αR. Topical administration of
extracts of red ginseng rhizomes (2 mg/mouse) and ginsenoside Ro (0.2 mg/mouse)
to shaved skin inhibited hair re-growth suppression after shaving in the
testosterone-treated C57BL/6 mice. These results suggest that red ginseng
rhizomes containing both oleanane- and dammarane-type ginsenosides are a
promising raw material for cosmetic use. This is the first report that
ginsenoside Ro enhances in vivo hair re-growth based on their inhibitory
activity against 5αR in the androgenetic alopecia model"

erectile dysfunction (ED) ... penile erection index (PEI) ... At a 7.5 mg
kg(-1) single dose, the percentage of responding rats was 53+/-7 with a PEI
of 337+/-72 compared with 17+/-6 with a PEI of 30+/-10 for control animals.
This PEI was significantly (P<0.001) higher than each single component and
than the sum of any two herbal components of Etana. When compared with
sildenafil citrate, Etana induced more pronounced PEI than 0.36 mg kg(-1),
but similar to 0.71 mg kg(-1) of sildenafil. Furthermore, full acute and
sub-acute toxicity studies showed no toxic effects of Etana. In conclusion,
this study describes a new and safe combination of herbal components that

of ginsam, a vinegar extract from Panax ginseng, on body weight and glucose
homeostasis in an obese insulin-resistant rat model - Metabolism. 2009
Jan;58(1):8-15 - "We evaluated the antihyperglycemic
and antiobesity effects of ginsam, a component of Panax ginseng produced by
vinegar extraction, which is enriched in the ginsenoside Rg3 ...
Insulin-resistant rats treated with ginsam had lower fasting and
postprandial glucose concentrations compared with vehicle-treated rats.
Importantly, overall glucose excursion during the intraperitoneal 2-hour
glucose tolerance test decreased by 21.5% (P < .01) in the treated rats,
indicating improved glucose tolerance. Plasma insulin concentration was
significantly lower in ginsam-treated rats. These changes may be related to
increased glucose transporter 4 expression in skeletal muscle.
Interestingly, when the data from both ginsam-treated groups were combined,
body weight was 60% lower in the ginsam-treated rats than in the controls (P
< .01). Liver weight and serum alanine aminotransferase concentrations were
also lower in the ginsam-treated rats. These effects were associated with
increased peroxisome proliferator-activated receptor gamma expression and
adenosine monophosphate-activated protein kinase phosphorylation in liver
and muscle. Our data suggest that ginsam has distinct beneficial effects on
glucose metabolism and body weight control in an obese animal model of
insulin resistance by changing the expression of genes involved in glucose
and fatty acid metabolism" - See

Panax Ginseng Enhances
Cognitive Performance in Alzheimer Disease - Alzheimer Dis Assoc Disord.
2008 Jun 17 - "ginseng group was treated with Panax
ginseng powder (4.5 g/d) for 12 weeks ... After ginseng treatment, the
cognitive subscale of ADAS and the MMSE score began to show improvements and
continued up to 12 weeks (P=0.029 and P=0.009 vs. baseline, respectively).
After discontinuing ginseng, the improved ADAS and MMSE scores declined to
the levels of the control group. These results suggest that Panax ginseng is
clinically effective in the cognitive performance of AD patients" -
