Hyssop gets its name from the Greek word azob, which means "holy herb". The plant has a long recorded history of use in cleansing rituals as described in several passages of the Holy Bible, including the significance of the plant being used to mark the doorways of Jewish homes in Egypt so that the plague might "pass over" its occupants.
The dried herb imparts a minty flavor to teas and other beverages, and is used as seasoning in Middle Eastern cuisine.
