Seen in context, remedy is immoderate (7)
I believe the answer is:
extreme
'immoderate' is the definition.
(similar in meaning)
'seen in context remedy is' is the wordplay.
'seen in' indicates a hidden word.
'EXTREME' is hidden in the letters of 'context remedy is'.
(Other definitions for extreme that I've seen before include "Very great; exceptional" , "Immoderate" , "Of the greatest intensity" , "over the top" , "stiff" .)
