The term "allopathy" was coined in 1842 by C.F.S. Hahnemann to designate the usual, or normal, practice of medicine (allopathy) as opposed to homeopathy, the system of therapy that he founded based on the concept that disease can be treated with drugs (in minute doses) and so produce the same symptoms in healthy people as the disease itself.

3. Having separate and mutually exclusive areas of geographical distribution.
allopatrically (adverb)
Characterizing populations or species; especially, those that are closely related to each other, that inhabit geographically different areas: "The allopatrically different species of birds were living on an island where the other group did not exist."
allopatry (s), allopatries (pl) (nouns)
The geographic isolation of populations of organisms or species; especially, from other populations that are closely related to them: "Allopatry involves different but related species that are always separated in some way in nature so they can't interbreed."

"Mountain ridges that separate small tropical valleys and which are very high and steep, and conditions on them that can form barriers, are examples of allopatries."
