Rue

a garden herb (Ruta graveolens) which the Pharisees were careful
to tithe (Luke 11:42), neglecting weightier matters. It is
omitted in the parallel passage of Matt. 23:23. There are
several species growing wild in Israel. It is used for
medicinal and culinary purposes. It has a powerful scent, and is
a stimulant. (See MINT T0002560.)
