TurkishStirfry: That raises questions about that slobbery greeting you receive from the Emir/Saurus upon purchasing him. Also, where did the hair come from that was used in the dispel potion? Sauruses or Sauri appear pretty bald to me.
The remake addresses this plot hole - if you talk to the Apothecary about the Saurus after you find out he's the Emir (but before you leave for Rasier, obviously), he mentions that he's going to look into a way to make a dispel potion that doesn't require hair.
Even if you don't do this, though, in the ending, the text changes to mention that it's a "specially prepared" dispel potion.
As for the slobbery greeting, well... the hero
is an attractive man...
