Incense resin (5)
I believe the answer is:
elemi
'incense resin' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elemi that I've seen before include "Oleoresin" , "Fragrant substance" , "Fragrant resin used as incense - Emile (anag)" , "aromatic resin" , "It's fragrance" .)
