With a list of ten (deca) or five (penta) keynotes per remedy, this handy little book is an excellent basis for further study. It can grow with the knowledge and experience of the user, as there is an empty page after each remedy. So users can make their own notes or add further information from other sources, enabling the book to become a trusty companion during daily practice.
When first introduced to the Materia Medica the student is bewildered by the mass of symptoms presented under each drug and he often seeks in vain for a way out of the seeming maze. “Decachords” will provide the earnest student with some necessary clues guiding him to a practical acquaintance with more frequently used remedies. By request, a number of additional remedies have been included at the end of the book, the indications taking the from of “Pentachords”. These bring the total of drugs dealt with up to one hundred and twenty. The notes are gathered from various sources. Due acknowledgments are made to Sir John Weir and Dr. Wheeler, whose valuable lectures have furnished much of the material. Well-known works by Drs. Allen, Cowperthwaite, Nash and others have also been drawn upon for many keynotes.
