Homeopathy is a form of alternative medicine that was discovered in the late 1700s. It encompasses the idea that ‘like heals like.’ In other words, natural substances that cause symptoms can also heal them by stimulating the immune system, suggesting that it produces the proper reaction to fight off disease and infection. With homeopathy, less focus is put upon the problem or diagnosis, and more upon the symptoms themselves. These symptoms are then stimulated by tiny amounts of a natural substance causing a similar reaction. The natural substance then replaces the disease, providing the immune system the strength to begin healing itself. Homeopathy is becoming an increasingly popular method of alternative medicine for dogs.
