Unguent (5)
I believe the answer is:
salve
'unguent' is the definition.
(I know that unguent can be written as salve)
This is all the clue.
(Other definitions for salve that I've seen before include "Ointment from the vales" , "Soothing cream" , "Soothing ointment - may also be applied to feelings" , "Welcome" , "healer" .)
