Streams able to put right ailments (5)
I believe the answer is:
rills
'streams' is the definition.
(rill is a kind of stream)
'right ailments' is the wordplay.
'right' becomes 'r' (common abbreviation).
'ailments' becomes 'ills' ('ill' can be a synonym of 'ailment').
'r'+'ills'='RILLS'
'able to put' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rills that I've seen before include "Rivulets, runnels" , "Small streams" .)
