The effect of BF-1 on food intake after restraint-induced stress. The net gram of food intake was measured by calculating the change of food weights before and after the voluntary intake. Standard (1x), diluted (0.3x; 0.3-fold of standard dosage) and concentrated (3x; 3-fold of standard dosage) BF-2 was tested. Among stress-induced rats, non (negative)- and acotiamide-treated animals were used as negative and positive controls, respectively. Values are mean ± S.D. *p < 0.05.
