Chloroform comes as a liquid that you soak a cloth in and hold over the persons mouth. It wouldn't be that hard to pin an injured person down and slap a cloth over their face to knock them out for a while.

Besides, if they're physically injured they likely don't have aura left anyway. So the whole worry about Aura becomes moot point.
