Ox bile is very helpful for folks who have had their gallbladder removed. It becomes more difficult to digest fats which can lead to "discomfort".
He recently had his gallbladder removed. I saw your comment, did some searching, and asked if he'd heard about it. Apparently he never had.
His wife has a variety of health issues, too, and it sounds like it may help her out, too, so two birds with one ox bile comment, apparently!
