Peg. There are some serious studies being done to complement or replace chemical treatments. Unfortunately, there has been little chance for conventional medecine to study them using controlled methods; hence wild claims of success from a variety of natural sources, which cannot be confirmed scientifically. This has the double whammy of not allowing conventional doctors the ability to use them as a an alternate treatment. All roughage should be eliminated from diet and carefully reintroduced to find "trigger" foods. Clearly this process can a does take years of carefull dieting. Some things like seeds and nuts have to be eliminated completely. I believe that Alison's reference to Acidophilus as a very interesting treatment bears study. Repairing damage from steroidal and antibiotic treatment is an area that natural medecine can help. The problem I see is mating the two disciplines and doing proper evaluations. Yours, Aye. Dave
