The regulation of sperm capacitation is important for successful fertilization. Ginsenosides, the biologically effective components of ginseng, have been found to enhance intracellular nitric oxide (NO) production and the latter has recently been indicated to play a significant role in modulation of sperm functions.

In Asia, ginseng is commonly included in herbals used for the treatment of sexual dysfunction. Recent studies in laboratory animals have shown that both Asian and American forms of ginseng enhance libido and copulatory performance.

Single doses of the traditional herbal treatment Panax ginseng have recently been shown to elicit cognitive improvements in healthy young volunteers. The mechanisms by which ginseng improves cognitive performance are not known. However, they may be related to the glycaemic properties of some Panax species.

Single doses of the traditional herbal treatment Panax ginseng have recently been shown to lower blood glucose levels and elicit cognitive improvements in healthy, overnight-fasted volunteers. The specific mechanisms responsible for these effects are not known.

To compare the anticarcinogenic effects of fresh, white, and red ginseng (Panax ginseng C A Meyer) roots and their saponins. 

Methods:
Lung adenoma in newborn N:GP (S) mice was induced by a subcutaneous injection of benzo(a)pyrene 0.5 mg. After weaning, ginseng powders or extracts were given in the drinking water for 6 wk. In the 9th wk the incidence and multiplicity of lung adenoma were counted.

Ginseng, a panacea in the Orient, has been widely investigated in the last two decades and found to possess a wide range of pharmacological activities including anti-fatigue properties, a transient regulatory action on metabolism and blood pressure, and an increase in the hypothalamo-pituitary-adrenocortical activities.

The root of Panax ginseng C.A. MEYER has been reported to have an anti-stress action.

Therefore, the effects of ginseng components on functions of adrenal medulla, which is one of the most important organs responsive to stress, were investigated in vitro.

Background & Objectives:
Panax ginseng has been used as a traditional medicine for many years mainly among Asian peoples for developing physical strength. We undertook this study to determine the immune-enhancement effect of P. ginseng using a forced swimming test (FST) and by measuring cytokine production in MOLT-4 cell culture and mouse peritoneal macrophages. 

The present study aims to demonstrate the ability of ginseng total saponin (GTS), ginsenosides Rg3 and Rb1 to reduce brain polyamine levels in immobilization-stressed gerbil mice. A previous study reported that ginsenosides had an anti-stress property.

So, we tested the anti-stress effect of ginseng by investigating the brain level of polyamine, a well-known stress stimuli marker. We determined the brain polyamine levels under 30-min immobilization stress in pretreating GTS (100 mgkg(-1), oral), ginsenosides Rg3 and Rb1 (10 mgkg(-1), oral, respectively).
