Are Rhubarb Leaves Poisonous?

  • Oxalic acid: Rhubarb contains a high amount of oxalic acid, which can bind to minerals in the body and prevent their absorption. Because of this, it is recommended to consume rhubarb in moderation and to avoid consuming large amounts of raw rhubarb leaves, which contain even higher concentrations of oxalic acid and can be toxic if consumed in large quantities. Symptoms of toxicity include mild gastrointestinal symptoms, as well as more serious problems, such as kidney stones and kidney failure.

It’s important to note that the nutritional content of rhubarb can vary depending on factors such as the variety of rhubarb, where it was grown, and how it was prepared.
