This is a book about homeopathy: what it is, how it arose and developed, where it is today. It is a critical book but it presents its criticism from the standpoint of knowledge. Anthony Campbell was consultant physician at The Royal London Homeopathic Hospital (now The Royal London Hospital for Integrated Medicine) and is a past Editor of the British Medical Homeopathic Journal (now Homeopathy). No prior knowledge is assumed but that does not mean it is suitable only for beginners. Even if you have read a good deal about acupuncture you will probably find that you view it differently when you have finished.
