Ginseng has been one of the most popular herbs said to improve human exercise performance. The purpose of the present study was to investigate the effect of ginseng supplementation on lactate threshold in physically active young men. Sixty men from the Naval Medical Corps, Royal Thai Navy, aged 17- 22 years old, were randomized into either the ginseng or placebo group. The ginseng group took 3 grams of 100% ginseng orally, while the placebo group took an equal amount of lactose powder each day, for 8 weeks. Daily administration of 3 g of ginseng for an 8-week period did not improve lactate threshold nor did it affect physical performances. Therefore, ginseng supplementation did not exert an ergogenic property on aerobic fitness enhancement in well-fit individuals.

Ginseng is a very popular food supplement, and is in high demand particularly in China and surrounding countries. Raising ginseng is something that can be very profitable in combination with maple sugaring. It requires patience, hard work, some capital investment and is by no means guaranteed income. Age, appearance, and method of cultivation determine the price received by the grower. Ginseng is sorted into 40 different grades based on root shape, color, taste, and age. The current estimated market price for field cultivated ginseng can be between $12 to $20 per dry pound.

Ginseng has long been reported to have aphrodisiac properties. It is likely that such effects reflect the non-specific tonic or adaptogen actions referred to above. However, recognition of importance of NO (nitric oxide) in the mechanism of penile erection led to consideration of the rabbit as a model. NO is released from non-adrenergic, non-cholinergic nerves. It relaxes both the human and rabbit penile corpus cavernosum... permitting penile erection. Since endothelial cells and perivascular nerves in the corpus cavernosum contain NO synthase, ginsenosides may relax the corpus secondary to the release of endogenous NO. By means of an in vitro superfusion technique, ginseng extract relaxed the corpus cavernosum in a concentration-dependent manner.

Ginseng is sweet and sligtly bitter in flavour, slightly warm in nature, and acts on the heart, spleen and lung channels. It can strongly invigorate the original Qi (yuan qi), quickly restore collapse and slowly tonify the deficiency. It is the first important herb to treat collapse due to extreme deficiency of original Qi caused by overwork. It invigorates spleen-qi and lung-qi, promoting the production of the body fluids s. When the original Qi is invigorated the nevous system is calmer. Therefore ren shen can tranquilize and can treat palpitations and insomnia.

Ginseng is widely available and comes in various forms. Typical recommendations for the powder form range from one-half to one teaspoon per day. A common method is to add one-half a teaspoon of the dried, pulverized root to one cup of boiling water. The dose for this method is two cups per day. Note: You probably won't get an immediate energy boost; instead, your energy should increase over time. Some herbalists suggest using ginseng for a month, followed by a two-month hiatus.

Ginseng has been used in traditional Chinese medicine for thousands of years as an aid to prevent and treat many kinds of disease. It has been called a panacea. After intensive pharmacological investigations during the last 50 years, ginseng has developed a great reputation for marked effects on the body. From the viewpoint of preventive medicine, ginseng tonics can stimulate the body’s defence system. This aids the body to overcome some insults and to adapt to stressful environments. This paper will review the source, chemistry, pharmacology and clinical applications of ginseng.
