Herbal mixture left out in recovery centre (5)
I believe the answer is:
rehab
'herbal mixture' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'left out in recovery centre' is the wordplay.
'left' becomes 'red' (red can informally mean communist).
'out' means to remove the last letter.
'in recovery centre' becomes 'hab' (I can't explain this - if you can you should give a lot more credence to this answer).
'red' with its final letter taken away is 're'.
're'+'hab'='REHAB'
Can you help me to learn more?
(Other definitions for rehab that I've seen before include "Treatment centre (abbrev.)" , "Health-restoring process" , "Treatment for dependency" , "Restorative care" , "Process of restoring, eg, an addict to health" .)
