2 cents worth...
a very small informal study was conducted a few years back by my four
(of five) children. To sleep outside on a deck, built directly over a
creek, and retain an adequate blood supply upon awakening the next
morning, each child would voluntarily swallow a peeled garlic clove
(single or a good sized chuck of a too-large-to-swallow 0ne) WHOLE.
Mashed garlic on french bread or lots of garlic in salad/sauce wasn't
enough for protection. They all swore (heck and gee whiz) by it.
