Boericke's Pocket Manual is the classic, usually well worn reference book, found in the library of most naturopathic and homeopathic physicians. If I could only have one book about homeopathy, this would be it. William Boericke was an MD/Botanist, and his works form the basis of most modern materia medicas. This volume includes homeopathic uses of hundreds of plants and natural substances, many of which are not found elsewhere. Latin and common names are cross referenced, a list of remedy duration of action, and a limited repertory is provided. While the Indian re-printed edition is a poorly bound version from the 1927 manuscript, my copy is still holding up after 10 years. It is an excellent, affordable reference source. The newer versions can be more costly, but are no more valuable to me than my old copy, which I still carry, with my own practice notes in the margins.
