We reported 2 cases of plantar keratosis (59 years of age, female/39 years of age, male) successfully improved by intake of hot water extract of Coix lacryma-jobi L. var. ma-yuen Stapf with Husks. Both subjects were administered coix seed extract containing food for 20 weeks. The lesions improved gradually after 12 weeks, and almost cured by 20 weeks of administration. Although the food seemed to be effective in these cases, further studies are needed to define the optimal dose and duration.
