You can do anything you want, but none of the greatest natural healers of the 20th century suggested brown rice purges with parasite cleanses, that I am aware of. The greatest master herbalists *did* recommend a combination of IF 1 and 2 (or very similar recipe) to aid tens of thousands of patients over the course of over 50 years.
What is happening with the IF 2? Maybe we can figure out what is going on so that you can tolerate it. :)

When I read this it reminded me of what Dr. Christopher always said, it goes something like this; if it doesn't come up when you plant it in the garden then you don't eat it lol!
Every time I eat something I shouldn't I think of good ole Doc Christopher! :)
