After administering 15 g/day of Ninjin-Yoei-To (NYT) for one week to healthy people whose NK activity had already been increased by physiological response, a further increase in NK activity was observed after two days. This increased level of NK activity continued during the administration of NYT for a one-week period. The maintaining and reinforcing effect on the immune surveillance system by NYT may be useful for prevention of carcinogenesis.
