If you are thinking that the only way to cure impotence is to use man made drugs think again because, there are some time tested herbs which have been used for centuries to get men harder erections and even better, the herb will also improve overall health and wellness at the same time which is something synthetic drugs cannot do. These herbs are doing exactly the same as man made drugs but naturally, with no dangerous side affects. If you don't secrete enough nitric oxide, you simply will never get an erection but the good news is you can boost levels with the following herbs - Ginseng, Cnidium and Horny Goat Weed and another advantage of these herbs is they prevent PDE5 build up which can cause serious erection problems. If you want a hard erection, you need to have strong blood flow to the sex organs and to let the blood into them you must secrete high levels of nitric oxide. Man made drugs can of course give you an erection but they don't increase libido and this leaves many men.

Nitric oxide is the chemical which allows the blood vessels to widen and allowing more blood into the penis to create an erection.
