The FDA says that since it regulates chemical drugs, and all living things produce chemicals, then all living things fall under FDA jurisdiction.
But I'm sure that's nothing to worry about. Right? They'd never use that authority to say, stop you from using something from your own body to cure itself or anything ... would they?
Well ok, maybe they would, but they wouldn't take it any further than that ... I mean, it's not like the Federal Government wants to take control over decisions about health care, is it?
