Basil or dill
I believe the answer is:
herb
I believe this is a double definition.
'basil' is the first definition.
(basil is an example)
'dill' is the second definition.
(thesaurus)
(Other definitions for herb that I've seen before include "Plant with leaves or seeds used medicinally" , "Maybe sage" , "Type of plant used in medicine" , "Savoury plant" , "Plant used for flavour" .)
