(Gosh I can't explain this very well, sorry if I hurt your brain) I think that maybe because Emilia's projecting her [i]own[/i] emotions onto someone, it could be as if like a parasite - a foreign invader of sorts because its not him actually feeling it, but its her making him to so. I think of it like that, but I'm not too sure whether I explained it very well D:

Ah ok, I understand what you mean now, but nonetheless, I don't think it would fit either way. After all, it heals physical injuries, even if she's imposing her emotions, it's not a physical change to his brain, it's not physical damage, what then could his healing factor fight against?

Of course this is all just theorising, but I do enjoy theorising super powers perhaps a little too much XD
