Castor oil, slippery elm, powdered toothepaste, and bromo seltzer keep me from aging.
I’ve never had the need to use slippery elm for myself. But I use it for my dogs when they get diarrhea. The stuff is magic. I boil a teasponn in a cup of water until it becomes “gooey” (about 3 or 4 minutes) then add honey, and give a few tablespoons to the dog every 4 hours. It works better and quicker than anything we’ve ever been given by the vet.
