Rhubarb is one of those magical items that is very short in season and a treat when its here. Tart in taste and the perfect addition to any crumble but did you know there’s more than meets the eyes?
Rhubarb leaves can be poisonous. If eaten in large doses, the leaves can cause throat closure due to their high levels of oxalic acid, which is an acid used in stain remover and metal polish.
90% of the world’s sweetest rhubarb is located in The Rhubarb Triangle of West Yorkshire, England. England was the first country to grow rhubarb for eating (not just medicinal purposes).

Rhubarb is a fruit! But not botanically speaking. Rheum rhabarbarum is a part of the buckwheat family. It’s also known as the smartweed family which also includes sorrel.

Rhubarb is a laxative. 3000 years ago, rhubarb was used specifically for medicinal purposes. It was dried and consumed as a purgative (cleansing of the bowels), a carminative (reduce excess gas), and for ulcer treatment.
