Rue, scientifically known as Ruta graveolens, is a perennial herb belonging to the Rutaceae family. Native to the Mediterranean region, it has a strong history in traditional medicine and folklore, known for its distinct aroma, vibrant appearance, and reputed protective qualities.

Characteristics

• Appearance: Rue is a small shrub that grows up to about 2-3 feet tall. It has blue-green, feathery leaves that emit a potent, sometimes unpleasant smell when crushed. The plant produces clusters of small, yellow flowers that bloom in the summer.
• Aroma and Taste: The leaves have a strong, acrid smell, and a bitter taste that makes it less suitable for culinary use compared to other herbs.
• Toxicity: Rue contains volatile oils and compounds, such as rutin and furocoumarins, which can cause skin irritation in some people. It’s advised to handle the plant carefully to avoid contact dermatitis.

Common Uses

• Traditional Medicine: Rue has been used in traditional systems, particularly in the Mediterranean, for a range of purposes, from supporting digestion to easing discomfort. However, it’s generally advised to avoid large doses due to potential toxicity.
• Repellent and Protection: Historically, rue was used as an insect repellent and as a symbol of protection. In folklore, it was thought to ward off negative energies.
• Ornamental: Due to its attractive blue-green foliage and bright flowers, rue is often grown as an ornamental plant.

Due to the potential risks associated with its use, rue should be handled carefully and generally avoided in high quantities, especially in homemade remedies or culinary uses.
