Although many of us think of rhubarb as a fruit and use the stems similar to other fruits such as in a jam, compote, chutney or in cake, rhubarb is considered a vegetable.
Rhubarb is incredibly healthy and fits perfectly with Metabolic Balance. It contains large amounts of vitamin K and C, potassium, and calcium. This vegetable is also packed full of malic acids, various glycosides, tannins, essential oils and pectin which can be soothing for the intestine. Rhubarb is perfect for “internal cleansing”. The contained anthraquinones strongly stimulate the digestive system and have a laxative effect.
