Inflammation reducer (7)
I believe the answer is:
steroid
'inflammation reducer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for steroid that I've seen before include "Type of hormone" , "Body-building drug" , "Compond such as many hormones and vitamins" , "Type of drug, maybe anabolic" , "Editors (anag.)" .)
