They developed a water-wash and sieving method of extracting starch from the root, similar to what we use today. Native people prized arrowroot as a dietary staple and medicinal plant. It was applied to wounds and insect bites to draw out toxins. Today, moms the world over trust this classic starch in baby biscuits and instant cereals.
