Would alchemy fall under the category of science or magic?

It is magic through science. That's how I see it.

Etrigans is Magic. But the one in Full Metal is described as science.

Magic.

Personally, I'm putting it into fringe science. Like some sort of esoteric part of chemistry we don't fully master yet.

Magic

It's one of those grey areas, with elements of both. I'll call it fringe science.

Hokum.

Science because magic ain't real

@jayc1324:

So far.

A bit from both. Or least some dark and mysterious science.

A scientific reaction that's activation energy requires magic.

So both IMHO.

Either or both.

Magic

Fictionally speaking I think it really depends upon what your definitions for science and magic are or from within what universe they arise. For example what Victor Frankenstein (in Mary Shelley's classic) uses is a mixture of science and alchemy which frees up the narrative to leave the cause of the monster's resurrection to remain ambiguous.

If you are talking about the real world then by definition alchemy would fall into the category of magic while chemistry occupies the same category within science.
