I must leave medicine out for local (7)
I believe the answer is:
endemic
'local' is the definition.
(I've seen this before)
'i must leave medicine out' is the wordplay.
'must leave' suggests deleting specific letters.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'medicine' with 'i' taken out is 'medcine'.
'medcine' anagrammed gives 'ENDEMIC'.
'for' acts as a link.
(Other definitions for endemic that I've seen before include "Confined to a particular area" , "Native to (med.)" , "locally confined" , "Restricted to a certain area" , "Only found in a particular region, or regions" .)
