Shaelee is both a natural healer and has some magical abilities.  Her knowledge won't go anywhere, of course, but I think that she will get at least a part of her healing abilities back that are magical.  Or never lose all of them.  Maybe because she never wanted to be a priestess, never wanted to take the vow of chastity and was forced into it by her aunt, she doesn't lose all of her ability to heal.  She will assume she does and not even try to heal, though.
