Cures heartbreak over Collingwood (9)
I believe the answer is:
therapies
'cures' is the definition.
Although both the answer and definition are plural nouns, I don't see how one could define the other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for therapies that I've seen before include "aids to recovery" , "Treatments designed to relieve or cure" .)
