There are a few well known herbal supplements that work well for impotence and erectile dysfunction.
These come from nature and can transform your body.
Most people think they do not need them or they do not work.
But if you have an erection problem then what do you have to lose? These herbs are:

• Muira Puama-Increases libido and sexual function
• Guarana-Increases libido, stimulates and dilates blood vessels
• Maca- An aphrodisiac
• Tibullus Terrestris-Fertility and helps raise hormone levels
• Horny goat weed- Increase levels of testosterone
• Tongkat Ali-Testosterone booster
• Catuaba- Aphrodisiac, dilates and relaxes blood vessels
• L-argnine- Increases the amount of nitric oxide and helps dilate blood vessels, resulting in an erection.
  
• Gingko Biloba- Boosts oxygen supply to the blood, it enhances blood flow, particularly to the penis
• Yohimbe-Aphrodisiac and helps dilate small blood vessels, particularly in the penis
• Ginseng- Increase stamina

Put these drugs into a combination together and you have a dynamite pill.
