Description
Common rue is an evergreen Mediterranean subshrub usually growing 30–50 cm tall, rarely to 100 cm. Its blue-green, two- to three-times pinnate leaves give off a strong, pungent odour when bruised. Greenish-yellow flowers appear from June to November. For centuries it was an important medicinal, culinary and protective ('anti-witch') herb, but it is now regarded as toxic and phototoxic. Germany's Commission E rejected therapeutic use in 1989.
Externally the plant was applied for joint pain, skin conditions and warts. Caution: skin contact combined with sunlight can cause severe blistering burns (phytophotodermatitis).
Historical documentation only — do NOT use
These internal applications are historically documented. This plant is highly toxic — self-treatment can cause severe poisoning or death. For documentation only, explicitly NOT a recommendation.
Historically a leaf infusion was used for menstrual and digestive complaints. Internal use is now discouraged because of abortifacient effects, liver toxicity and poisoning risk – strictly forbidden in pregnancy.
In Mediterranean cuisine tiny amounts of leaf were used as a strong, bitter seasoning. Traces only – larger amounts are toxic.

Phototoxic (severe blistering phytophotodermatitis on skin contact plus sunlight). Abortifacient and teratogenic – strictly forbidden in pregnancy. High doses cause gastric pain, vomiting, liver damage and even death; mutagenic and hepatotoxic.
Harvested part: Flowering aerial parts (leaves and shoot tips)
- Furanocumarine (Psoralen, Bergapten, Xanthotoxin)Glycoside
Light-sensitizing furanocoumarins – the main cause of phototoxicity.
- RutinFlavonoid
The eponymous flavonoid glycoside, capillary-strengthening.
- Ätherisches Öl (2-Undecanon)Essential oil
Essential oil dominated by 2-undecanone; responsible for the pungent smell.
- Acridon-Alkaloide (Rutacridon, Skimmianin)Alkaloid
Alkaloids such as rutacridone and skimmianine; partly mutagenic.
