I can't speak to the legality but the current setup is shady. I am much more well informed about medications than the average and very anti homeopathy. It still takes me 5 minutes of reading the fine print of several bottle to avoid accidently picking up a homeopathic treatment.
It might be better if there was just a regulation that the active ingredient(s) in each product had to be printed on the front of the box, in letters as big as the rest of the branding. That would correctly label homeopathy ("water"), as well as chase some of the woo out of actual medicine.
