Frankincense, Copal, Turpentine, Balsam, Kauri at the end give this resin (5)
I believe the answer is:
elemi
'this resin' is the definition.
(elemi is a kind of resin)
'frankincense copal turpentine balsam kauri at the end' is the wordplay.
'at the end' says to take the final letters.
The final letters of 'frankincense copal turpentine balsam kauri' are 'ELEMI'.
'give' acts as a link.
(Other definitions for elemi that I've seen before include "It's fragrance" , "Fragrant substance" , "Fragrant tree resin used as incense - I'm Lee (anag)" , "Fragrant resin used as incense - Emile (anag)" , "Tree resin; ie, elm (anag.)" .)
