Drinks sent east (4)
I believe the answer is:
teas
'drinks' is the definition.
(tea is a kind of drink)
'sent east' is the wordplay.
'sent' is an anagram indicator (send can mean to excite or stimulate).
'east' anagrammed gives 'TEAS'.
(Other definitions for teas that I've seen before include "Afternoon meals" , "Beverages from leaves" , "Beverage made by steeping leaves in water" , "Hot drinks" .)
