Parsley-family member (5)
I believe the answer is:
anise
'parsley-family member' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anise that I've seen before include "Aromatic Mediterranean plant" , "Plant giving ouzo flavour" , "Plant providing flavour similar to liquorice" , "Plant with liquorice-flavoured seeds" , "Plant with seeds used as flavouring" .)
