Abstract:
Adlay has been used as a traditional Chinese medicine and nutrient for its beneficial effects on bowel movements and skin care. This study examined the effect of enzymatic degradation product of adlay, “Super Hatomugi” (SPH) on human skin and the intestinal flora in a randomized, double-blind placebo-controlled study. The subjects were divided into three groups: 500mg SPH, 1000mg SPH, and placebo, taken daily for 4weeks. Hematological and skin condition examinations as well as an analysis of intestinal flora were performed 2weeks before and 10weeks after the start of the SPH intake. Skin condition was improved by SPH intake as revealed by a reduction in the number of nucleated epidermal cells. In addition, an increase in the fecal population of Bacteroidetes followed the SPH intake. These results show the possibility that SPH improves the skin condition and changes the proportions of intestinal flora.
