I seem to remeber that a recent "House of Lords" paper concluded that alternative medicines can be categorised into 4 groups,
Those that we know work.
Those that we don't know whether they work or not.
Those that we know don't work.
Those that we know do harm.
I seem to think that homeopathy sit's in the 3rd of 4th category. (Although I'd be happy to stand corrected.)
You could argue that traditional medicine/surgery doesn't always sit in the 1st category, although hopefully, we're constantly striving to change that
