Homeopathic products are extreme dilutions of some active ingredient. They are often so diluted that they don't contain any active medicine. Homeopathic products are permitted for sale in the U.S. due to legislation passed in 1938 sponsored by a homeopathic physician who was also a senator. The law still requires that the U.S. Food and Drug Administration (FDA) allow the sale of products listed in the Homeopathic Pharmacopeia of the United States. However, homeopathic preparations are not held to the same safety and effectiveness standards as conventional medicines.
Oscillococcinum is used for symptoms of influenza infections ("the flu") and H1N1 (swine) flu.
