The reason garlic is so toxic, the sulphone hydroxyl ion penetrates the blood brain barrier, just like DMSO, and is a  specific poison for higher life forms and brain cells.

 We discovered this much to our horror, when I was the world's largest manufacturer of ethical EEG biofeedback equipment.  We'd have people come back from lunch that looked clinically dead on the encephalograph, which we used to calibrate their  progress. "Well, what happened?" " Well, I went to an Italian restaurant and there was some garlic in my salad dressing!".  So we had 'em sign things that they won't touch garlic before classes or we were wasting their time, and money and my  time. I guess those of you who are pilots or have been in flight tests... I was in flight test engineering in Doc Hallan's  group in the 1950's.
 
 The flight surgeon would come around every month and remind all of us: "Don't you dare touch any garlic 72 hours before  you fly one of our airplanes, because it'll double or triple your reaction time. You're three times slower than you would  be if you'd [not] had a few drops of garlic." Well, we didn't know why for 20 years later, until I owned the Alpha-Metrics  Corporation. We were building biofeedback equipment and found out that garlic totally desynchronizes your brain waves.
 
 So I funded a study at Stanford and, sure enough, they found that it's a poison. You can rub a clove of garlic on your  foot - on the sole of your foot - and you can smell it shortly later on your wrists. So it penetrates the body. This is  why DMSO smells a lot like garlic: that sulphone hydroxyl ion penetrates all the barriers including the corpus callosum in  the brain.
 
 Any of you who are organic gardeners know that if you don't want to use DDT, garlic will kill anything in the way of  insects.
 
 Now, most people have heard most of their lives that garlic is good for you, and we put those people in the same class of  ignorance as the mothers who at the turn of the century would buy morphine sulphate in the drugstore and give it to their  babies to put 'em to sleep.
 
 If you have any patients who have low-grade headaches or attention deficit [disorder], they can't quite focus on the  computer in the afternoon, just do an experiment - you owe it to yourselves.
 
 Take those people off garlic and see how much better they get, very,very shortly. And then let them eat a little garlic  after about three weeks. They'll say: "My God, I had no idea that this was the cause of our problems." And this includes  the de-skunked garlic's, Kyolic, some of the other products. Very unpopular, but I've got to tell you the truth.
 
 Bob Beck also found in his research on human brain function in the 1980's that garlic has a detrimental effect on the  brain and researching this further he learned that many yoga groups and philosophical teachings caution against the use of  garlic and onions as they are known to interfere with meditation practices. Some aware individuals have actually described  themselves as experiencing brain fog after having garlic.
