Handling medicine (9)
I believe the answer is:
treatment
I believe this is a double definition.
'handling' is the first definition.
(I know that handling can be written as treatment)
'medicine' is the second definition.
(I know that treatment is a medicine)
(Other definitions for treatment that I've seen before include "Hospital care" , "Action to help" , "Method of handling or healing" , "NHS care?" , "patient progress" .)
