I think definately, emotional distress will open wide the door for any illness--consequently if you don't work on the emotional issues TOO, you'll keep getting hit with illness after illness even if you do get them healed, which you can---the results just won't last, but I do think there is a purely physical component that needs addressing. Maybe before they started dumping soo many toxins on us, you might have been able to deal with things only thru healing your emotional field, but I think now-a-days, you will also need to deal with the physical component, too, since we've all pretty much been steeped in toxins from birth, so a good de-tox is always helpful.
