Parsley or oregano (4)
I believe the answer is:
herb
This clue is a double definition.
'parsley' is the first definition.
(thesaurus)
'oregano' is the second definition.

(Other definitions for herb that I've seen before include "Plant used in medicine or cookery" , "Basil, for example, is one" , "Aromatic plant used in cookery" , "man's name" , "Eg, sage" .)
