Supposed healer in Gujarati medicine (4)
I believe the answer is:
time
'supposed healer' is the definition.
(proverbially, 'time heals all wounds')
'in gujarati medicine' is the wordplay.
'in' says the answer is hidden in the clue.
'TIME' is hidden in the letters of 'gujarati medicine'.
(Other definitions for time that I've seen before include "Bird" , "Finite duration" , "Great healer, so they say" , "Tempo; occasion" , "Its detonation is delayed" .)
