This info has been around for years and is disputed on both ends. It's not really cooked garlic, its raw fresh garlic and it has to be introduced direct to the bloodstream to work. It will actually seperate the two brain hemispheres supposedly, and then interferes with neuro electrical transmission. It is said that a lot of tribal people's use it for hunting and that's where the idea came from to test it. Raw onion is supposed to do something similar too.
