I think you'll find Tom is the one usually recommending diluting with water
and I agree with that but I've said before pineapple juice worked for me.
I think I may have benefitted from less than the 15 drops I used especially if I'd used water. I didnt have nausea though and as I already had chronic diarrhea
(a symptom of colitis in case you didn't know) and that gradually reduced so I must have done something right.
So are you saying Tom's tests are wrong or inaccurate?
