(For other uses, see Arrowroot (disambiguation).) Arrowroot is a starch obtained from the rhizomes (rootstock) of several tropical plants, traditionally Maranta arundinacea, but also Florida arrowroot from Zamia integrifolia, and tapioca from cassava (Manihot esculenta), which is often labelled as arrowroot. Japanese arrowroot, Pueraria lobata, also called kuzu, is used in similar ways.
