Criticise expert primarily advocating non-specific cure (7)
I believe the answer is:
panacea
'non-specific cure' is the definition.
'panacea' can be an answer for 'cure' (panacea is a kind of cure). I am not certain of the 'non-specific' bit.
'criticise expert primarily advocating' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'expert' becomes 'ace' (ace is a kind of expert**).
'primarily' says to take the initial letters.
The first letter of 'advocating' is 'a'.
'pan'+'ace'+'a'='PANACEA'
Can you help me to learn more?
(Other definitions for panacea that I've seen before include "A cure-all for diseases or troubles" , "Cure-all in a canape" , "Cure for all ills" , "wonder drug" , "that's going to help a lot" .)
