(2) Pharmacology

The main active agents in Panax ginseng are ginsenosides, which are triterpene saponins. The majority of published research forward the medicinal activity of Panax ginseng has focused in succession ginsenosides. (3) These are the compromises to which some ginseng consequences are now standardized.

Research reviews (24) postulate that extracts of Panax ginseng affect the hypothalamus-pituitary-adrenal axis and the immune scheme which could account for many of the documented meanings Animal models and in vitro studies mentioned in these reviews (24) indicate that Panax ginseng enhances phagocytosis, natural killer confined apartment activity, and the production of interferon; improves physical and mental performance in mice and rats; causes vasodilation; increases resistance to exogenous stres factors; and affects hypoglycemic activity.

Efficacy

Panax ginseng is used primarily to improve psychologic function, exercise performance, immune function, and conditions associated with diabetes (Table 1) Traditional Chinese medicine and many in every one's mouth research studies (5-8) often use harvests that combine ginseng with other herbal medicines or vitamins. Because of the use of combination issues and the limitations of a studies on ginseng (e.g., poor methodologic quality, research focusing in succession healthy volunteers, small sample size, unstandardized ginseng preparations, varying doses), it is difficult to draw conclusions about near of the clinical effects of ginseng. Many research trials have been performed forward the standardized Panax ginseng extract Ginsana (G115)

imports ON PSYCHOLOGIC FUNCTION

Trials investigating the consequences of Panax ginseng on various psychologic parameters have shown positive issues no effects, or both. In common study (9) of 112 healthy offers older than 40 years, the administration of 400 mg by means of day of the standardized ginseng harvest Gerimax for eight weeks ariseed in better and faster simple reactions and abstract thinking, if it were not that no change in concentration, memory, or subjective experience.

The be deriveds of two small studies, (1011) each including about 30 young, healthy offers who received 200 mg of G115 daily for eight weeks, showed improvement in certain psychomotor functions (i.e., better attention, processing, and auditory reaction time), social functioning, and mental health. However, a certain of the effects present at the fourth week disappeared on the eighth week. (11)

A cogitation of 384 postmenopausal women who were randomized to receive placebo or ginseng for 16 weeks showed improvements in three subset of a Psychological General Well-Being index. (12) [Evidence flat A, randomized controlled trial (RCT)] In addition, a small thought (7) of 20 healthy young proffers who received a single 400-mg dose of ginseng base improvement in cognitive performance, secondary memory performance, spe of performing memory tasks, and accuracy of attentional tasks. However, another thought (13) showed no effect in succession positive affect, negative affect, or total temper disturbance in 83 young healthy presents who took 200 to 400 mg by day of G115 for eight weeks.

Similarly, a research of 31 healthy men who took 200 or 400 mg of G115 daily for eight weeks place no change in physiologic or psychologic rejoinders to submaximal or maximal exercise. (16) [Evidence horizontal B, lower quality RCT] In another meditation (17) a different product standardized to 7 percent ginsenosides and administered at 200 mg by day was given to 28 healthy young adults for 21 days. No ergogenic imports were demonstrated, including no change in maximal oxygen consumption, exercise time, workload, plasma lactate of the same height hematocrit, or heart rate.
