As this quote shows, it seems that bacta use has pushed other medical treatments out as obsolete:
"Everyone uses Bacta. We've been using it so long, it's replaced most conventional medicine."
Did other medical treatments exist? How advanced were they? (No need for a list, just some general information please).
Edit:
Whilst alternatives to bacta are nice, I was hopping if someone could say if other procedures as well as medicines existed, like anti-biotics, surgery, blood transfusion or if they had been replaced by bacta.
