A return to health (8)
I believe the answer is:
recovery
'a return to health' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for recovery that I've seen before include "Rally" , "A return to original state, health say" , "A return to good health" , "A return to a normal state of health" , "Green shoots could be a sign of this" .)
