Asian Ginseng - Usage, Dosage, Side-Effects of Asian Ginseng

Diabetes, Type 2
Although American ginseng has been better researched for this purpose, both types of Panax ginsengs have been shown to lower blood sugar levels in those with type 2 (adult onset) diabetes.

Fertility/Sexual Performance
Ginseng is widely believed to be capable of enhancing sexual performance. However, studies in people to investigate this are limited. In animal studies, Panax species of ginseng have increased sperm production, sexual activity, and sexual performance. A study of 46 men has also shown an increase in sperm count as well as motility.

Immune System Enhancement
Ginseng is believed to enhance the immune system, which could, in theory, help the body fight off infection and disease. In one study, in fact, giving people ginseng before getting the flu-vaccine did boost their immune response to the vaccine compared to those who received a placebo.

Menopausal Symptoms
Ginseng may have estrogen-like activity. Two well-designed studies evaluating red Korean (Asian) ginseng suggest that this herb may relieve some of the symptoms of menopause, improving mood (particularly feelings of depression) and sense of well-being.

Mental Performance and Mood Enhancement
Individuals who use ginseng often report that they feel more alert. Preliminary studies do suggest that this feeling has scientific merit. Early research shows that ginseng may improve performance on such things as mental arithmetic, concentration, memory, and other measures. More research in this area, although not easy to do, would be helpful.

On the other hand, for those who report that ginseng elevates their mood, the science thus far does not support that this herb changes your mood if you are otherwise healthy.

Physical Endurance
There have been a number of studies in people looking at the effects of ginseng on athletic performance. Results have not been consistent, with some studies showing increased strength and endurance, others showing improved agility or reaction time, and still others showing no effect at all. Nevertheless, athletes often take ginseng to increase both endurance and strength.

Respiratory Disease
In patients with severe chronic respiratory disease (such as emphysema or chronic bronchitis), daily treatment with ginseng improved respiratory function, as evidenced by increased endurance in walking.

Asian Ginseng for Stress
Ginseng has long been valued for its ability to help the body deal with stress. A study of 501 men and women living in Mexico City found significant improvements in quality of life measures (energy, sleep, sex life, personal satisfaction, well-being) in those taking ginseng.

Plant Description

The ginseng plant has leaves that grow in a circle around a straight stem. Yellowish-green umbrella-shaped flowers grow in the center and produce red berries. Wrinkles around the neck of the root tell how old the plant is. This is important because ginseng is not ready for use until it has grown for four to six years.

What's It Made Of?

Ginseng products are made from the ginseng root, and the long, thin offshoots, called root hairs. Both Asian and American ginseng contain ginsenosides, saponins that are ginseng's active ingredients. In addition to ginsenosides, Asian ginseng also contains glycans (panaxans), polysaccharide fraction DPG-3-2, peptides, maltol, B vitamins, flavonoids, and volatile oil.

Available Forms

White ginseng (dried, peeled) or red ginseng (unpeeled root, steamed before drying) is available in water, water-and-alcohol, or alcohol liquid extracts, and in powders or capsules.

It is important when buying ginseng to read the label carefully and make sure that you are purchasing the type of ginseng that you want. If you are looking for Asian or American ginseng, look for a Panax species, not Siberian ginseng (Eleutherococcus senticosus) which, although there is some overlap, has different actions and side effects overall.
