Abstract
We evaluated the long-term safety of eight adult volunteers (male 7, female 1: average age 47.4 years) ingesting powdered foods containing Coix-seed Reactive Derivatives (CRD/2.2g/day or 4.4g/day) for 1 year 8 months to 5 years (average 2 years 9 months). Body weight, vital signs (blood pressure, pulse rate), peripheral blood test, blood biochemical test, etc. were observed. We also investigated the presence or absence of side effects. The results showed no notable changes in vital signs or blood test results. From the above, it was speculated that long-term intake of CRD would not pose a safety problem. We plan to continue the study by increasing the number of observation cases in the future.
