Word with salts or Downs (5)
I believe the answer is:
epsom
'word with salts or downs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for epsom that I've seen before include "Poems about the race-course" , "Downs" , "Derby race track" , "English town, of course?" , "Location of English Derby" .)
