Jamaica pepper (8)
I believe the answer is:
allspice
'jamaica pepper' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for allspice that I've seen before include "Pill case (anag.)" , "Pimento or Jamaica pepper" , "fragrant plant" , "Aromatic dried fruit of a Caribbean tree" , "Dried aromatic fruit from the West Indies" .)
