Wear it in good health (6)
I believe the answer is:
amulet
'wear it in good health' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for amulet that I've seen before include "Charm to protect from evil" , "Charm worn to ward off evil" , "Lucky trinket" , "Lucky charm, talisman" , "Protective ornament" .)
