Do we know what causes greyscale? It could just be skin infection that can be treated by paste. Afterall, it's only contagious if you touch it and the one maester said that Jorah should have just cut off his arm to prevent it from spreading in the first place. Of course, if it does eventually go to the mind...it may be more than just a skin infection.
