To be fair, is it really hard for "alternative medicines" to be worse than homeopathy? By definition homeopathic "remedies" do absolutely nothing, so being worse should be easy. ;)
"Worse" could mean that the theory behind the mechanism of action for homeopathy is worse. However, in this case the worse is about it causing harm, and the extent of harm from homeopathy is pretty much limited to patients not seeking needed medical treatment.
Scientifically speaking homeopathic remedies are placebos, and many studies have shown that placebos are remarkably effective treatments with minimal side effects.
