is miracles from the vault book from health sciences institute a lot of bunk?

Yes and no. The info is the same stuff you can find on the web with a little research, so why bother paying? Whether these work as "cures" is debatable. Some stuff has real effects on the body others just work by psyching you into feeleing better for a few months. Even if you come across an alternative medicine cure that sounds good look for some kind of research. If it's really works, research will back it up.
