Well, still no explanation on liver phases... I've read the general info which is also accessible from Gerson's site. But here we know about Niacin and Niacinamide with regards to liver I and II phases and their correction. I would like to know how coffee enemas reflect that. Do they stimulate the 1st or 2nd phases or both, or reduce one of those while stimulating the other... Also don't forget that there is the 3rd phase...
