Country home to the east of health centre (5)
I believe the answer is:
spain
'country' is the definition.
(Spain is an example)
'home to the east of health centre' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'to the east of' means one lot of letters go next to another.
'health centre' becomes 'spa' (I've seen this before).
'in' put after 'spa' is 'SPAIN'.
(Other definitions for spain that I've seen before include "Pains badly to be in the country" , "EU country" , "ditto" , "location of Estoril" , "It pains one to be out in this country" .)
