Definition & Meaning of "rue"

What is "rue"?

Rue is an herbaceous plant with blue-green leaves and small, yellow flowers, native to southern Europe and western Asia. It has a strong, pungent aroma and bitter taste, which comes from the presence of compounds such as rutin and volatile oils. Rue has a long history of use in traditional medicine and culinary practices, although its use has declined in modern times due to its potential toxicity. In culinary applications, rue leaves were traditionally used to flavor sauces, soups, and meat dishes, particularly in Mediterranean cuisine. However, it is important to note that rue contains toxic compounds that can cause skin irritation and gastrointestinal upset if ingested in large quantities. As a result, rue is not commonly used in modern culinary practices, and its use as a medicinal herb is also discouraged. It is primarily grown today as an ornamental plant or for its historical and cultural significance.
