While I think the parent comment does not understand what "homeopathic" means, I don't think it's correct that "[homeopathy] does not involve plants of any kind." My understanding is that the "active" ingredients are often plant based - after all, it was cinchona overdose that started this mess. If that's the case, homeopathic remedies don't contain the plants anymore (through over-dilution), but homeopathy as a process involves plants.
