I have this book since its twelfth edition, we are at the 16th and it is only better, ESSENTIAL, we must have, it comforts us, heals us, saves us. It is THE book of homeopathy to have. Accurate, easily understood, complete (as far as I can tell) is on our travels and even heals family pets. Of course you need to know what we suffer for not making mistakes but with a little attention and -parfois- the help of a professional, you come to heal prsque all emergencies. If so, homeopathy also treats emergencies. I did buy my whole family and many friends around us.
