I need to refer your questions to Emofree.com. They have everything and more you need to know about EFT. My goal was to help gargajan with his knee problem. EFT will likely do that if it's properly applied.
I'm not able to devote too much time to a forum as I am really busy with other stuff.
EFT works for me and it does no harm. Any one considering themselves a healer would be well served to add EFT to their tool kit.
