Can Garlic Replace Viagra for Erectile Dysfunction?

I stumbled upon a BBC health article about garlic’s use for erectile dysfunction treatment.

A study was conducted on eight men with impotence. And for three months, each of those men were fed four cloves of raw garlic daily. The results were that six out of seven of the men who participated in the study did notice an improvement on their erectile function by just eating garlic.

The magical component of garlic that has Viagra-like effect is allicin, which helps increase blood flow and thus enhance erection hardness and endurance.

Garlic may be an effective and natural alternative to Viagra, but is it worth the smell?
