Strange poems about some salts (5)
I believe the answer is:
epsom
'some salts' is the definition.
(as in Epsom salts)
'strange poems' is the wordplay.
'strange' indicates an anagram.
'poems' with letters rearranged gives 'EPSOM'.
'about' is the link.
(Other definitions for epsom that I've seen before include "The Oaks and Derby are run here" , "Racetrack" , "Home to the Derby and the Oakes" , "- Salts are a purgative" , "Derby course" .)
