This book is not about heartburn. The first part of the book is about all manner of digestive problems, and then even about disorders purportedly related to digestive disorders. The second part of the book suggests that good diet (especially yogurt), enemas, and something called probiotics will cure all diseases, and therefore incidentally also heartburn (which thus has served only as a marketing come-on to lure in buyers). I believe there is much to be learned from alternative medicine, but this book actually offers very little rigorous (supported) information. For entertainment, and in closing, let me quote a tidbit. "Make the coffee enema by boiling six heaping tablespoons of ground coffee (not instant) in two quarts of water for fifteen minutes, cooling to a comfortable temperature, and straining..." It is probably a very good idea to let that boiling coffee cool a little before the anal consumption, but why is instant coffee not good, and how does this fix heartburn?
