Indications: Rue is a herb with an ancient history. The genus name " Ruta " comes from the Greek work " reuo ", to set free, showing its reputation as a freer from disease. Its main use is the regulation of menstrual periods, where it is used to bring on suppressed menses. The oil of Rue is a powerful abortifacient, therefore the plant is best avoided during pregnancy. The other area of usage is due to the plant's anti-spasmodic action. It may be used to relax smooth muscles, especially in the digestive system where it will ease griping and bowel tension. The easing of spasm gives it a role in the stopping of spasmodic coughs. It also increases peripheral circulation and lowers elevated blood pressure. If the fresh leaf is chewed, it will relieve tension headaches, ease palpitations and other anxiety problems.
To quote King's Dispensatory - " Its action is chiefly directed upon the uterus, and is capable of exciting menorrhagia, inflammation and miscarriage. It has been successfully used in flatulent colic, hysteria, some nervous complaints, epilepsy, and as an excellent vermifuge. Rue is a stimulant to the genito-urinary tract, and, in small doses, might prove a remedy in atonic conditions of those parts. Owing to its affinity for the nervous system, it relieves irritation and pain when administered in small amounts.
CAUTION: Avoid during pregnancy.
Combinations: For use in the regulation of periods it will combine well with False Unicorn Root and Life Root.
Preparations & Dosage: Infusion: pour a cup of boiling water onto l-2 teaspoonfuls of the dried herb and leave to infuse for l0-l5 minutes. This should be drunk three times a day. Tincture: take l-4ml of the tincture three times a day.
