Origin of Rue
A native of Europe, it is an ornamental, shrubby herb with a strong, aromatic, bitter or acrid scent and has tough, woody branches and small, smooth, bluish-green leaves. Mustard-yellow, fringed 4-petalled flowers appear in summer, followed by 4-lobed capsules.
In ancient medicine, the herb was a favored remedy as an antidote to poison and was seen as a magic herb by many cultures and as a protection against evil. It was used for nervous afflictions, digestive problems and hysterics.
Rue essential oil is considered toxic, an abortifacient, an irritant to the mucus membranes, a neurotoxin, and causes sun sensitivity due to photo toxicity
Rue oil is extracted from the fresh herb by steam distillation.
The main chemical components are 2-nonanone, 2-nonyl acetate, 2-undecanone, 2-butanone, psoralen, bergaptene and xanthotoxin.
Rue essential oil should not be used in aromatherapy as it is a hazardous oil that can burn and irritate the skin.
