Pine extract (5)
I believe the answer is:
resin
'pine extract' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for resin that I've seen before include "frankincense, for instance?" , "Fiddler's need" , "Sticky substance exuded by pine trees" , "Unprocessed pine secretion" , "Sticky material" .)
