THIS PRODUCT IS DANGEROUSMy daughter took this product for 6 months and developed toxic poisoning as a result. She developed tremors, had trouble walking, experienced short term memory problems and confusion. Doctors thought it was a brain tumor or ALS. Finally diagnosed by Harvard hospital doctors as experiencing toxic poisoning by bismuth which is the ingredient in Devrom. It took her 3 months to get it out of her system and now she is healthy again. This medicine needs to include warnings.
