Pulverised leaves in producing ointment (8)
I believe the answer is:
vaseline
'ointment' is the definition.
(Vaseline is an example)
'pulverised leaves in' is the wordplay.
'pulverised' is an anagram indicator.
'leaves'+'in'='leavesin'
'leavesin' anagrammed gives 'VASELINE'.
'producing' acts as a link.
(Other definitions for vaseline that I've seen before include "petroleum product" , "Brand of petroleum jelly" .)
