Finland’s Poison Information Centre is cautioning consumers about the toxicity of rhubarb leaves during peak season. While rhubarb stalks are a popular and healthy seasonal treat, the plant’s leaves contain poisonous substances and should never be consumed. The warning, issued via social media, emphasizes that only the stalks are safe for eating, and even those must be cooked before consumption. The centre highlights that many home gardeners may be unaware of this danger. Rhubarb is currently in season and widely available, making the warning particularly timely. Improper handling can lead to poisoning, so awareness of which parts of the plant are edible is crucial.
