Oriental blend of teas (4)
I believe the answer is:
east
'oriental' is the definition.
(thesaurus)
'blend of teas' is the wordplay.
'blend of' indicates an anagram (I've seen this in other clues).
'teas' anagrammed gives 'EAST'.
(Other definitions for east that I've seen before include "Bearing of 90 degrees" , "Asia" , "One of four at table" , "On most maps it's right!" , "the way the Wise Men came from" .)
