Thank you very much for all the useful information. I will definitely keep you up to date about the results of the test and my condition. Yesterday I purchased the slippery elm herb, and now I will buy the probiotics and the olive leaf extract. In a Healthy Food Store I found they sell a few brands of probiotics and one of them was non-dairy. It contained four types of bacteria. Is this the best one to buy? (I will look for the UDO's brand as recommended by you)
