Query: An Oldie, but a GOODIE!

The Vinegar Book is a short book of folklore and historical solutions using apple cider vinegar. It is filled with old home remedies, but is not meant to be used as medical advice or medical care. It also has some interested solutions to cleaning problems using vinegar. I bought the book because I had heard of the benefits of using apple cider vinegar for nighttime leg cramps. I was surprised, but it worked! It's an interesting read on this product, to say the least.
