Wild roots are hand harvested from December to March when the sap gathers in the root, carried down from the mountains on backpacks and cleaned. Each root is hand-cut into chunks that are crushed into fibers, soaked and rinsed, creating a thick paste. The paste is repeatedly washed and filtered in cold mountain spring water until it becomes a pure white starch. The kuzu starch is then allowed to dry naturally for 90 days, crushed into small chunks and packed.

The kuzu Pueraia lobata plant is a prolific, tough, fibrous vine with heart-shaped leaves that was used as a food in China for more than 2,000 years, and praised in Japanese poetry and legend as a bracing health food and ideal thickener for over one thousand years. Its roots are among the largest in the world, ranging in length from three to seven feet and weighing between 200 to over 400 pounds. Traditionally the leaves, seeds, flowers and roots were used in making vegetable dishes, noodles, dumplings, beverages, desserts and pickles. The vines were used to weave baskets and in making clothing, fishing line, and paper.

In traditional Oriental medicine kuzu is valued as a digestive aid, to strengthen vitality, and fortify the body in cold weather.
