We investigated the effects of ajoene on intestinal IgA production. Ajoene (1.35, 4.5, and 13.5 µg/kg/d) was administered to mice for 4 weeks. The fecal IgA level in the 13.5 µg/kg/d group increased after 3 weeks. The intestinal IgA level also increased in a dose-dependent manner upon ajoene administration. An oil-macerated garlic extract, with 1500 µg/g of ajoene, enhanced the intestinal IgA production.
