Most run away from remedy (7)
I believe the answer is:
nostrum
'remedy' is the definition.
(I know that nostrum is a type of remedy)
'most run away' is the wordplay.
'away' indicates an anagram (letters move away from their original places).
'most'+'run'='mostrun'
'mostrun' anagrammed gives 'NOSTRUM'.
'from' is the link.
(Other definitions for nostrum that I've seen before include "Ineffective medicine" , "Quack remedy or pet scheme" , "Quack cure" , "Some think it helps" , "Supposed remedy" .)
