Hmmm let's see it works great on animals I wonder if they just knew it was going to work.
I used it on my infant several times for colic relief...she must have saw it coming and her expectation was so great it knocked her out and made her sleep peacefully for 12 hours.
I still use it on her at 2 but by now her expectation is that it's gonna heal me so it works!!
get a life
try it for yourself and see what happens
