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 Palestine. It is used for medicinal and culinary purposes. It has a powerful scent, and is a stimulant.
