Common Rue is a perennial herb which grows up to 2-3 ft in height. This native of Southern Europe has established well in India’s Western Ghats. Its aromatic, evergreen bluish-green leaves have medicinal qualities, and the yellow flowers and fruits blossom from June to September.
In Ayurveda, the plant has an antiseptic and anti-inflammatory effect. The juice of the plant has expectorant, antispasmodic properties which both promotes the onset of menstruation and treats painful menstruation. In Kerala the oil of Rue is used as a traditional remedy for the common cold and cough. Historically, the fresh rue was rubbed on floors to repel fleas and other insects.
