Dried plant product, a treatment for warts (5)
I believe the answer is:
straw
'dried plant product' is the definition.
The definition and answer can be both substances as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'a treatment for warts' is the wordplay.
'a treatment for' is an anagram indicator (I've seen this in other clues).
'warts' anagrammed gives 'STRAW'.
Can you help me to learn more?
(Other definitions for straw that I've seen before include "Dry stalk of grain" , "Plant fibre used as fodder" , "'It is the last ..... that breaks the camel's back'" , "corny stuff" , "Pale-yellow - through which one can drink" .)
