For anyone interested in discovering the fountain of youth, the 12 cell salts are IT. It is precisely BECAUSE this book was written in the 1930s that it's so important. This was when Big Pharma was just beginning to get its stranglehold on the medical "profession," and i use that term loosely. Most doctors don't have a clue. For Pete's sake, the Father of Medicine, Hippocrates, made it absolutely clear that a doctor needed to check the stars before performing any kind of surgery. No wonder so many people die on the operating table.
Anyway, the cell salts (triturated minerals) are the builders of the body. IMHO, this book is probably the most important book on the planet for those who are interested in regeneration, age reversal, obtaining perfect health, etc. This is a huge Secret that no one is supposed to know about. Read it for yourself and decide.
By the way, the salts are inexpensive (Hyland's brand).
