Cure sipped, say, for indigestion (9)
I believe the answer is:
dyspepsia
'for indigestion' is the definition.
(synonyms)
'cure sipped say' is the wordplay.
'cure' is an anagram indicator (I've seen 'cured' mean this).
'sipped'+'say'='sippedsay'
'sippedsay' with letters rearranged gives 'DYSPEPSIA'.
(Other definitions for dyspepsia that I've seen before include "internal upset" , "stomach complaint" , "It was enough to make any man sick" , "it could result from rushing courses" , ""It gives me wind problem"" .)
