So I've been researching this because I am in sticky situation. According to the FDA baking soda is a food. Its when compounded that it becomes a medication. Baking soda if considered a medicine would have to have to be labeled as a medicine. Baking soda is not even labeled as a medical food unless compounded. There is no standard or procedure just like prune juice, butter, pickles, bananas, yogurt. All of which can alter bodily function. Baking Soda is used as a tooth paste or mouth wash or on a tender tooth much like peppermint tea is used for upset stomach; no order needed it comes from the kitchen. We would obtain an order for sodium bicarb like we get an order for Pepto Bismal. I'll keep researching
