Arrowroot is the starch of the Maranta Arundinacea (dictionary says). It is considered to be highly digestible and was used in infant foods. Tapioca is derived from the cassava root (of the genus Manihof). I believe the root itself is poisonous, unless it is thoroughly processed. Considering possible plant toxins, I would say tapioca is somewhat suspect. I use arrowroot in the place of cornstarch for thickening stirfries and gravies. (Don't use flour at all due to celiac condition.) Lynnet
