Native to the Mediterranean, as well as Macaronesia and Southeast Asia. Different sources attribute between 8 and 40 different species of Rue.
Rue is very easily reproduced by cuttings.
Cut a small branch from an existing plant, and strip the leaves from the bottom 2/3 of the branch.
Place in a pot of well draining soil and pinch the soil around the branch to hold it in place. In wetter climates, the branch can be placed directly in the garden.
If it is very dry where you live, trim the tops of the leaves to prevent water loss and consider covering with a cloche or misting regularly with water.
The more space you give it, the bigger it will grow. Some sources recommend up to half a meter (one and a half feet) on all sides, but can be planted closer.
Seeds and rooted cuttings can be planted outside in the spring or summer.
The ideal conditions for Rue are dry and sunny. Watering once or twice a week is sufficient. Keep dry to encourage flowering.
Rue prefers rocky, chalky, well draining soils. Does not tolerate compact earth or soil with a high percentage of clay.
Sand (without salt), small rocks, and powdered eggshells can be dug into the earth in preparation for the Rue plant.
Protect from winds and cold temperatures.
Tolerates frost until -15 °C (5 °F) but thrives in warmer climates.
Usually resistant to pests, but can be vulnerable to aphids and white fly when under watered.
Can be toxic depending on the dose, so it is advised to keep out of reach of small children and non-human animals. Wearing gloves when harvesting will protect against phototoxic burns.
Fresh Rue has more essential oil, and is thus more potent than the dried herb.
Infusion in warm water is more effective at extracting the properties of the plant than tinctures using alcohol.
Extracted oil may be given on sugar, or in hot water.
Large doses (more than 100 mL of the oil or approximately 120 g of the leaves in 1 dose) can cause violent gastric pain, vomiting, and systemic failure.
Side effects can include mood changes, rash, sensitivity to sunlight, dizziness, sleep problems, spasms, and damage to the liver, kidney, and stomach. Better avoided by people with kidney, liver, stomach, and intestinal weaknesses.
The recommended doseis 0.5 to 30 g of fresh herb daily or 65 mg of essential oil.
Tests done on humans involving daily doses of 30 mg during 3 months found no abnormal hepatic function.
