Harvesting: The shoots are
gathered before the plant flowers.
Uses: The bitter leaves, rich in iron and other
minerals, when used sparingly add a musky tang to food and
to grappa and other alcoholic drinks. Rue is a stimulant,
abortifacient and strengthens capillaries. Its antispasmodic
action treats high
blood pressure, epilepsy,
and
colic. A leaf wash treats
tired
eyes. The dried leaf is a
powerful insecticide and a germicide for wounds. The oil is
used in the perfume industry. The stem sap may cause a skin
rash.
