weird marketing strategies

So I was buying some mouthwash, and saw the weirdest ad line on a nearby toothpaste I've encountered yet.

In the prominent byline place near the brand name, where normally you'd see claims like "recommended by dentists" or such it advertised with "compatible with homeopathy". Just what? And it wasn't a toothpaste of the organic/all natural/no mineral-oil derived ingredients kinds or some other niche product either.
