Condemn complicated cures (5)
I believe the answer is:
curse
'condemn' is the definition.
(thesaurus)
'complicated cures' is the wordplay.
'complicated' indicates an anagram.
'cures' anagrammed gives 'CURSE'.
(Other definitions for curse that I've seen before include "Execrate" , "Imprecation or oath" , "Wish harm on" , "Profanity" , "Malediction or expletive" .)
