8 Wonderful Health Benefits Of Rhubarb

Scientifically termed as Rheum rhabarbarum, rhubarb belongs to the Polygonaceae family. Having a sour taste and thick stalks, the vegetable-fruit ranges in colour from pink to red to pale green. Rhubarb is normally consumed after cooking and sweetening it with sugar. During the early times, only the roots of rhubarb were used, and that too only for medicinal purposes. However, the stalks of rhubarb are now used in the preparation of sweet soups, jams, sauces, pies, tarts, crumbles, cocktails, and rhubarb wine [1] .

Also called as the pie plant, rhubarb is packed with various benefits that are advantageous to your health. Rhubarb has a taste similar to that of green apples as well as celery [2] . Only the stalks of the plants are consumed because the triangular leaves of the plant are harmful to your health due to the presence of high content of oxalic acid. The stalks should not be stored in cold temperatures because the harmful acid can migrate to the stalk, rendering it unfit for consumption [3] .
