How does Chinese herb Panax Ginseng work for impotence?

Condition analysis:
Asian ginseng, often used for its ability to improve mental and physical vitality, shows great promise among impotence herbs.

Studies in Asia have shown that this herb taken over a period of two to three months may improve sexual function and sperm count and motility. This supplement may also reduce fatigue which can lead to impotence issues.

Ginseng is generally safe, although large amounts may cause over-stimulation leading to insomnia or irritability. Combining this herb with caffeine may also lead to over-stimulation.

Instructions:
Tribulus (Tribulus terrestris): This is another important selection in the list of herbs for impotence. It has been shown to increase testosterone levels, especially in those whose levels may be low, and increase sexual desire.

This herb works at the hormonal level by increasing Gonadotropin-releasing hormone (GnRH), in turn increasing LH and FSH which increase testosterone release. Tribulus is a safe herbal treatment, although some people do notice an upset stomach.
