Comic actress Imogene
I believe the answer is:
coca
'comic actress imogene' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for coca that I've seen before include "Source of drug" , "S. American drug crop" , "Narcotic shrub" , "Shrub whose leaves are chewed in the Andes as a stimulant" , "South American plant from which a narcotic drug is obtained" .)
