USA: Homeopatía "No funciona"...recordar.

“Creer que la homeopatía funciona … 
es creer en la magia“.
Timothy Caulfield

Homeopathy, which dates back to the late-eighteenth century, is based on the view that disease symptoms can be treated by minute doses of substances that produce similar symptoms when provided in larger doses to healthy people. Many homeopathic products are diluted to such an extent that they no longer contain detectable levels of the initial substance. In general, homeopathic product claims are not based on modern scientific methods and are not accepted by modern medical experts, but homeopathy nevertheless has many adherents. 

In 1988, the Food & Drug Administration (FDA) issued a Compliance Policy Guide (CPG) entitled “Conditions Under Which Homeopathic Drugs May be Marketed,” which permitted marketers to distribute OTC homeopathic products without demonstrating their efficacy. 

Under the CPG, only homeopathic products intended solely for self-limiting disease conditions amenable to self-diagnosis of symptoms and treatment may be marketed OTC. 

The CPG requires that OTC homeopathic drugs be labeled as homeopathic and that their labeling display at least one major OTC indication for use. 

The FTC Act does not exempt homeopathic products from the general requirement that objective product claims be truthful and substantiated. 

Nevertheless, in the decades since the Commission announced in 1972 that objective product claims must be substantiated, the FTC has rarely challenged misleading claims for products that were homeopathic or purportedly homeopathic.
(...) 

In summary, there is no basis under the FTC Act to treat OTC homeopathic drugs differently than other health products. Accordingly, unqualified disease claims made for homeopathic drugs must be substantiated by competent and reliable scientific evidence. 
Nevertheless, truthful, nonmisleading, effective disclosure of the basis for an efficacy claim may be possible. The approach outlined in this Policy Statement is therefore consistent with the First Amendment, and neither limits consumer access to OTC homeopathic products nor conflicts with the FDA’s regulatory scheme. It would allow a marketer to include an indication for use that is not supported by scientific evidence so long as the marketer effectively communicates the limited basis for the claim in the manner discussed above.(Más)
