To examine the effect of overdosed functional food in liver-injured patients, we tried to investigate the dose effect of Allium sativum L. (also called garlic) extract on rats with CCl4-induced liver damage, by comparatively examinating the hepatic function of each group. 42 male Sprague-Dawley rats were selected and divided equally (n=7) into normal, control, positive control, and three experimental subgroups (E1, E2 and E3), respectively. For each kg of body weight, hepatic injury was induced by intraperitoneal administration of $0.5\;m{\ell}$ (0.20 g/kg/day) $CCl_4$, which was diluted in equal amount of olive oil, once a day on every other day for total 5 times. Hot water extraction was performed using domestically cultivated organic garlics, and the obtained extract was injected by sonde, once daily during 4 weeks, to each experimental subgroups by different dosage of 0.35 g/kg(E1), 0.70 g/kg(E2), 1.40 g/kg(E3), respectively. Results showed that the injection of garlic extract positively influenced the physiological activation which lowered the oxidative stress, changed the toxicity, and functionally improved the hepatic condition. Comparing the dose effect between the three experimental subgroups (E1, E2, E3), results of the maximal-dosed subgroup (E3) showed less significance compared with the lower-dosed subgroups(E1 and E2), which seems to resulted from the (increased) toxicity of garlic.
