Rhubarb is a popular vegetable often used in pies, tarts, and other desserts, prized for its tart flavor and versatility in both sweet and savory dishes. However, while the stalks of the rhubarb plant are edible and widely consumed, the leaves are a different story altogether. Eating rhubarb leaves can have serious health consequences due to their high concentration of toxic compounds. In this article, we will delve into the specifics of what happens if you eat rhubarb leaves, the reasons behind their toxicity, and how to safely enjoy rhubarb while avoiding its harmful parts.
Introduction to Rhubarb and Its Toxicity
Rhubarb, scientifically known as Rheum rhabarbarum, is a member of the Polygonaceae family. It is native to Asia and has been cultivated for centuries, not only for its culinary uses but also for its medicinal properties. The plant consists of large, leafy greens and long, fleshy stalks. While the stalks are safe to eat and are used in a variety of dishes, the leaves contain high levels of oxalic acid and anthraquinone glycosides, which are toxic to humans and animals.
