Cure for all ills (7)
I believe the answer is:
panacea
'cure for all ills' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for panacea that I've seen before include "wonder drug" , "Universal medicine" , "Cure-all in a canape" , "universal solution" , "A soldier in the World War One Aus. and NZ Army Corps" .)
