An epidemic of obesity in both humans and companion animals has spawned a large trade in weight loss supplements. Some, such as those which contain ephedrine, have been eliminated from the market in the United States and Canada due to potential adverse cardiac effects.
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', or that a substance that is capable, in toxic doses, of producing a set of symptoms is also capable, in much lower doses, of curing the same set of symptoms regardless of their perceived cause.
The underlying philosophy of all alternative medical therapies is the 'holistic' approach, in which the patient is treated as a whole being rather than as a collection of organs and parts. The patient is treated as an individual rather than as a diagnosis, and the treatment is determined by the way that he or she is responding to illness.
