Healing or cosmetic preparation (8)
I believe the answer is:
ointment
'healing or cosmetic preparation' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ointment that I've seen before include "Soothing cream 98)" , "Medicinal unguent" , "Medicinal application" , "Preparation for the skin" , "Medicinal rub" .)
