Back in 1965 I first read a book by Dr. D.C. Jarvis called Vermont Folk Medicine. It was most likely the best book I ever read about natural cures. It remain one of my favorite books because of its simplicity and straightforward methods.
He details how he cured so many maladies with a simple solution(s)...apple cider vinegar and honey. He used these to cure everything from morning sickness to arthritis. I still recommend using the combination to "fix" acid reflux. Yup. It works.
Dr. Jarvis was ahead of his time (or behind, depending upon your view) and his book is available here from Amazon. It is probably in its 100th reprinting. But, it's worth the 7 bucks.
