Out of curiosity i thought i might read the latest newsletter issue on the main page of curezone. the newsletter was about someone who was testing to see whether or not the stones produced from a Liver Flush were actually stones from the liver or whether they were produced by the o/l and g/f mixture. she used various dyes in the mixture to see whether they found themselves in the stones or not....believe it or not the bright red dye she used found its way into the liver stones ...rather worrying eh. i suggest u have a look at the newsletter to judge it for yourself, but i was wondering if anyone could shed some positive light on this find! thanks!
