"This book is a reference guide. The techniques and suggestions found in it are designed to help you make more informed choices about your child's and your own health. This book is not intended to provide personal medical advice or treatment or to be a substitute for your usual medical care. Any consideration given to changes in your own or your child's care should be thoroughly discussed with your personal physician. Many medical problems are totally unrelated to the environment and these require the individual attention of the doctor who is most knowledgeable about your child's or your own specific health needs. Never taper, stop, or alter your own or your child's medications without specific guidance or advice a personal physician."
