Effects of Korean red ginseng (KG) and western ginseng (WG) on body temperature, pulse rate, clinical symptoms and hematological changes in human were studied after administration p.o. with Korean red ginseng and western ginseng for 10-days. KG was more effective in keeping homeostsis in than western ginseng in the changes of body temperature and pulse rate. KG was more effective in low body temperature and SOEVMIN (소음인), while inducing tachycardia especially in SOYANGIN (소양인) and TAEEUMIN (태음인). WG tended to drop temperature abruptly and also descended pulse rate with greater range than KG. KG and WG could cause side effects such as headache and gastrointestinal syndromes and induce hypertension or hypotension abruptly in specific constitutions. However, KG and WG did not cause abnormal changes in urinalysis and hematology.

Ginsenf Radix (Panax ginseng C. A. Meyer) has been traditionally used as a herbal medicine for many therapeutic or prophylactic purposes in the oriental countries such as Korea, Japan and China for at least two thousand years and also extensively studied in the modern scientific field of chemistry, biochemistry and pharmacology. The herb is now also indicated for use as tonic or a prophylactic and restorative agent for enhancement of mental and physical capacities, in case of weahess exhaustion tiredness loss of concentration, impotence, cold limbs, during illiness anuor convalescence. Ginseng is commonly used in the form of detections, extract and powderl and ginseng products, in the form of capsules tablets and drinks. And also ginseng radix has been widely traditionally prescribed as an important comuonents of manny Chinese prescriptions or alone in various diseases and for health with its different dosages. Nowadays since rinsenf can be generally classified into food or medicine in many nations, it is very difficult to give any exact desnition on the dosage, which may be of particular importance in clinical applications. In addition, the establishment of the reasonable dosage is currently of great significance to meet the demand for such wide applications. Accordingly in this review paper we summarized the dosage of ginseng on the basis of oriental medical books oriental and western pharmacopeias and modern scientific clinical data. The recent survey demonstrated that the averare dosare of finsenf is considered to be three to four grams per day unless prescribed apart, while one to two grams per day in western countries from the western viewpoint of classification of ginseng as a medicine, surrorted by the dosage of not more than one gram per day in most clinical studies. For that reason, it seems likely that the dosage in western countries is ascribed to the safety of ginseng considering side or unwanted effects. Consequently whether the differences of dosage between oriental and western countries depend on dietary habits and races should be closely investigated. Besides, further studies on the pharmacokinetics and bioavailability of ginseng components in clinical trials need to be done to decide optimum dosage of ginseng.

Background: Past studies suggested that ginseng extracts and ginseng-derived molecules exerted significant regulatory effects on skin. However, no reports have described the effects of ginseng-derived nanoparticles (GDNPs) on skin cell proliferation and wound healing. In this study, we investigated whether GDNPs regulate the proliferation of skin cells and promote wound healing in a mouse model. Methods: GDNPs were separated and purified via differential centrifugation and sucrose/D2O gradient ultracentrifugation. GDNP uptake, cell proliferation and cell cycle progression were measured by confocal microscopy, CCK-8 assay and flow cytometry, respectively. Cell migration and angiogenic effects were assessed by the wound scratch assay and tube formation assay, respectively. ELISA was used to detect extracellular matrix secretion. The relevant signaling pathway was confirmed by western blotting. The effects of GDNPs on skin wound healing were assessed by wound observation, HE staining, and western blotting. Results: GDNPs possessed the essential features of exosomes, and they were accumulated by skin cells. Treatment with GDNPs notably enhanced the proliferation of HaCaT, BJ and HUVECs. GDNPs also enhanced the migration in HaCaT cells and HUVECs and angiogenesis in HUVECs. GDNPs increased the secretion of MMP-1, fibronectin-1, elastin-1, and COL1A1 in all three cell lines. GDNPs regulated cell proliferation through the ERK and AKT/ mTOR pathways. Furthermore, GDNPs facilitated skin wound healing and decreased inflammation in a mouse skin wound model. Conclusion: GDNPs can promote skin wound healing through the ERK and AKT/mTOR pathways. GDNPs thus represent an alternative treatment for chronic skin wounds.

Background: Black ginseng (Ginseng Radix nigra, BG) refers to the ginseng steamed for nine times and fine roots (hairy roots) of that is called fine black ginseng (FBG). It is known that the content of saponin of FBG is higher than that of BG. Therefore, in this study, we examined antitumor effects against MCF-7 breast cancer cells to target the FBG extract and its main component, ginsenoside Rg5 (Rg5). Methods: Action mechanism was determined by MTT assay, cell cycle assay and western blot analysis. Results: The results from MTT assay showed that MCF-7 cell proliferation was inhibited by Rg5 treatment for 24, 48 and 72 h in a dose-dependent manner. Rg5 at different concentrations (0, 25, 50 and $100{\mu}M$), induced cell cycle arrest in G0/G1 phase through regulation of cell cycle-related proteins in MCF-7 cells. As shown in the results from western blot analysis, Rg5 increased expression of p53, $p21^{WAF1/CIP1}$ and $p15^{INK4B}$ and decreased expression of Cyclin D1, Cyclin E2 and CDK4. Expression of apoptosiserelated proteins including Bax, PARP and Cytochrome c was also regulated by Rg5. These results indicate that Rg5 stimulated cell apoptosis and cell cycle arrest at G0/G1 phase via regulation of cell cycle-associated proteins in MCF-7 cells. Conclusion: Rg5 promotes breast cancer cell apoptosis in a multi-path manner with higher potency compared to 20(S)-ginsenoside Rg3 (Rg3) in MCF-7 (HER2/ER+) and MDA-MB-453 (HER2+/ER) human breast cancer cell lines, and this suggests that Rg5 might be an effective natural new material in improving breast cancer.

Since immemorial time Panax ginseng has been known as therapeutic, tonic, prophylactic and restorative agent in ancient Korea, China and Tibet and at present time is also used as a food supplement by Western societies (6). Various ginseng preparations in a form of powders, teas, tinctures or extracts, very often mixed with other substances are recommended for attenuation of degenerative processes caused by aging or fatigue, as well as for treatment of various disorders and diseases in several organs (e.g. circulatory and nervous system, liver, kidney). One of the most commonly known properties of ginseng is its possibly positive influence on physical and mental performance and general well being. Because of these adaptogenic properties promoting vitality and resistance to stress ginseng is considered as an ergogenic aid. During almost 40 years in many laboratories attempts have been made to find out whether ginseng can be 'a remedy for today's problems'. The present work is focused on the results obtained in human studies and concerning an influence of ginseng root extracts on exercise and mental performance.

Background: Fermented black ginseng (FBG) is produced through several cycles of steam treatment of raw ginseng, at which point its color turns black. During this process, the original ginsenoside components of raw ginseng (e.g., Re, Rg1, Rb1, Rc, and Rb2) are altered, and less-polar ginsenosides are generated (e.g., Rg3, Rg5, Rk1, and Rh4). The aim of this study was to determine the effect of FBG on wound healing. Methods: The effects of FBG on tube formation and on scratch wound healing were measured using human umbilical vein endothelial cells (HUVECs) and HaCaT cells, respectively. Protein phosphorylation of mitogen-activated protein kinase was evaluated via Western blotting. Finally, the wound-healing effects of FBG were assessed using an experimental cutaneous wounds model in mice. Results and Conclusion: The results showed that FBG enhanced the tube formation in HUVECs and migration in HaCaT cells. Western blot analysis revealed that FBG stimulated the phosphorylation of p38 and extracellular signal-regulated kinase in HaCaT cells. Moreover, mice treated with $25{\mu}g/mL$ of FBG exhibited faster wound closure than the control mice did in the experimental cutaneous wounds model in mice.

Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

Objective; Antistress effect of Korean red ginseng (RG) on postmenopausal women with severe climacteric syndrome (CS) were evaluated from the viewpoint of traditional KAMPO-medicine and Western medicine. Methods; All patients with CS were treated with daily oral administration of 6g RG for 30 days. Nine patients with CS were evaluated with the use of diagnostic scores for KI-deficiency (deficiency of vital energy) and OKETSU (blood stagnation) syndrome from the viewpoint of KAMPO-medicine. In the same patients with CS, peripheral blood levels of ${\beta}$-endorphin and total plasminogen activator inhibitor-1 (t-PAI-1) were measured before and after treatment with RG. In another group, 12 patients with CS, psychological test using CMI, STAI and SDS were performed from the viewpoint of Western medicine. Stress related hormones, such as ACTH, cortisol and DHEA-S in those 12 patients with CS were also measured before and after treatment with RG. Results; KI-deficiency score and OKETSU score in patients with CS were significantly (p<0.001) higher than those in patients without CS. After treatment with RG, both scores were markedly (p<0.001) decreased compared to before treatment with RG. ${\beta}$-endorphin levels in patients with CS were significantly (p<0.05) higher than those in patients without CS. Total PAI-levels in patients with CS were increased before treatment with RG. No significant difference, however, were observed between patients with and without CS. After treatment with RG, both levels of ${\beta}$-endorphin and total PAI-1 in patients with CS were significantly (p<0.001 and p<0.05, respectively) decreased compared to before treatment with RG. CMI and STAI scores in patients with CS were significantly (p<0.05) higher than those in patients without CS. SDS scores in patients with CS were also markedly (p<0.00l) higher than in those without CS. After treatment with RG, all scores decreased within normal range. DHEA-S levels in patients with CS were about a half of those without CS. Consequently, cortisol/DHEA-S (C/D) ratio was significantly(p<0.001) higher in patients with CS than in those without CS. Although the decreased DHEA-S levels were not restored to the levels in patients without CS, the C/D ratio decreased significantly (p<0.05) after treatment with RG. Conclusion; Reinforcement of vital energy and improvement of stagnant blood circulations by oral administration of RG were elucidated from the viewpoint of traditional KAMPO-medicine. From the viewpoint of Western medicine, effect of RG on postmenopsusal women with CS seemed to be brought about in part by not only an improvement of psychoneuroendocrine dysfunctions but also an amelioration of blood coagulation systems.
