Medical questions!

1. Does healing a wound with Mercalan magic cleanse it of infections and the likes?

2. How advanced is medical technology in a general sense?

3. Do pills exist? Or is it just potions, herbs, liquid medicines, etc.

(Edit) Bonus question

4. What would happen if one were to have nullstone impaled or lodged in them? I'm imagining something like the 'Origin Bullet' from Fate/Zero.
