Homeopathy is a distinct philosophy of medicine that has its roots in eighteenth-century Germany, and subsequently spread to Europe, India, Australia, South America, the United States, and Canada. The underlying basis of homeopathy is the principle that “like cures like”: the idea that a substance given at a toxic dose can produce a certain set of symptoms, but given in much lower doses, it can cure the same set of symptoms, regardless of their perceived cause. As veterinary homeopathy gains acceptance, there are an increasing number of veterinarians in private practice who possess the necessary training and experience.
