Homeopathy is a system of alternative medicine that was developed by Samuel Hahnemann (1755-1843). Makers of more than-the-counter (OTC) homeopathic drugs and merchandise that claim to remedy or treat ailments will now have to clearly disclose in their advertisements and labeling that: 1) there is no scientific evidence that they are efficient, and two) that any claims of effectiveness are only based on homeopathic theories, which are not accepted by modern day medical authorities.
