I'm sorry I can't/do all the things you ask me for. I'll give you what I can as I have the time, ok? I'll not saying I won't answer as much as I can, tho' it may not be all at once.
*I just started IP6 2 weeks ago after a friend did extensive research on it and felt it might help me. Be sure to NOT eat or take any other supplements within a couple of hours of taking it.
*Many have found Pau d'Arco tea to be much stronger and more effective than the Esssac tea.
*I was going to use the Wobenzyme but did much research after reading that the most important ingredients in the cancer enezyme therapy was Trypsin and Chymotrypsin. I found that Omnizyme FORTE (not plain Omnizyme but Omnizyme FORTE) has the largest amount I found. Trypsin - 125 mg
a-Chymotrypsin - 45 mg. I just began the Omnizyme Forte about a month ago.
I have no data or statics in regards to therapies against GIST, as GIST is so rare there's not been alot of research.
I still don't understand why they must remove SO MUCH on your dad??? That seems too drastic.
*About the Ellagic Acid comment. It was in a powerpoint presentation done by the doctor at iknowthecause.com website. That was the only sentence in the whole presentation that mentioned Glevic, but I grabbed on to it because I recognized the name of the drug.
I also use Graviola, can't remember if you said your dad was or not. The only other therapy that comes to my mind right now is the L-lysine, L-proline program that I am on. Have you heard about it? There's much good research on it and it's another one of those "natural" things that can't hurt.
