“Like cures like” is a natural principle first expounded by Hippocrates, the ancient founder of medicine. Centuries later, inspired by that idea, German physician Samuel Hahnemann found that some of the very substances that cause illness could also be used as cures—a discovery that led to the holistic healing system known as homeopathy. And the procedures he developed keep growing in popularity. Those who want to understand and apply homeopathy now have a comprehensive and authoritative reference that recounts its history, explains its enlightened principles, and—best of all—includes a full A-to-Z encyclopedia of remedies. So it’s simple to find safe, dependable treatments for colds, digestive ailments, skin irritation, sensory and nervous complaints, and many other diseases and conditions.
