At least homeopathic anything is not directly harmful in the context of ingesting it, because it contains no active ingredient.

It's only harmful in that people don't understand that it's bullshit and therefore believe that it works, and might skip actual effective treatment for whatever their ailment is in favor of cheaper (and totally ineffective) homeopathic whatever-the-hell. For that reason it should at least be regulated to the extent of having a big neon warning sticker on it that says, "This product is completely ineffective and accomplishes nothing other than setting your money on fire."

I'm all for outlawing it from a consumer advocacy standpoint because it's a scam, but otherwise it's just expensive water.
