Query: A doctor without this book is missing a lot ...

It is a book worth keeping all the time around you, in the clinic, in the ward and everywhere. I being a homeopathic doctor felt that in the beginning the text teaching almost everything needed to hunt for the clues, symptoms and signs to pin-point the problme and later serves as a reference. This new edition has many added features along with the all previous ones. I usually didn't need to consult anyother book while using it.
