Rhubarb

Rhubarb

A herbaceous plant from the Polygonaceae family. Cultivated and used in Asia since ancient times, it was then used as a tonic and laxative remedy. Its leaves are toxic, only the stalks (petioles) are eaten raw or cooked. It has only been cultivated in Europe since the sixteenth century and it was only consumed two centuries later for its gastronomic value.
