Aromatic ointment extracted from certain trees (6)
I believe the answer is:
balsam
(Other definitions for balsam that I've seen before include "Fragrant medicinal gum from tree" , "Fragrant resin used in medicine and perfumes" , "Fragrant substance exuded by some trees" , "Mal, BAs can produce a healing agent" , "Fragrant ointment" .)
