Three species are sold under the same common name and they are not interchangeable. This one is grown here and verified against a retained specimen, which is why the species appears on the label rather than only the common name.
The aerial part is used, not the root. Both are legitimate materials; they are simply different, and a label that says neither is telling you nothing.
