It has been shown that garlic and its main bioactive component, allicin, as natural chelating agents can reduce blood and tissue lead content in animal models. In this study the effect of allicin, alone or combined with meso-2,3-dimercaptosuccinic acid (DMSA), in decreasing lead content of blood and tissues of mice was evaluated. Swiss albino mice were exposed to 1000 ppm of lead in water for 35 days and then placed in various treatment groups including groups administered oral allicin, DMSA, or their combination. The concentrations of lead in blood, kidney, liver, bone and brain were measured using atomic absorption spectrophotometry. Both, allicin and DMSA decreased the blood and tissue lead concentration. There was an additive effect of the combined administration of allicin and DMSA in reducing bone lead. No side effect was observed in all treated groups. Combined use of DMSA and allicin seems to be a better choice in the treatment of chronic lead intoxication.

The objective of this study was to evaluate the effects of allicin, the main biologically active component of garlic clove extracts, on lead levels in different common carp tissues including liver, kidney, brain, bone, and blood following experimental lead poisoning. Fish were divided randomly into five groups depending on the combination of lead acetate and allicin treatments. Lead acetate exposure (7.0 mgL(-1), 10 days) caused a significant increase in mean Pb concentrations in all examined tissues in comparison to control unexposed fish (p < 0. 001). The results showed that allicin supplementation is effective in decreasing lead accumulation in all examined tissues of common carp. The promising ameliorative effects of allicin on tissue lead levels of common carp make it a good candidate for therapeutic intervention of lead poisoning. However, more studies are required to elucidate the pharmacokinetic effects of allicin and also molecular basis of the ameliorative properties of allicin in lead poisoning.

Garlic (Allium sativum) is known to reduce lead toxicity in some species of animals. The objective of this study was to evaluate the efficacy of allicin, one of the most active components of garlic, in the treatment of subacute lead intoxication in sheep. Nine female sheep weighing 25-29 kg orally received a daily dose of 80 mg/kg body weight of lead acetate for 5 days. The animals were then assigned into two groups. Group 1 did not receive any further treatment and was used as the control group and group 2 was treated orally by 2.7 mg/kg body weight of allicin twice daily for 7 days. Within one day following allicin treatment, group 2 blood lead levels were significantly lower than that in group 1 (mean of 616.9 microg/l and 290.02 microg/l, respectively; P < 0.05). Also, allicin treatment significantly reduced kidney lead content and considerably reduced bone and ovary lead contents. These results suggest that allicin might have some therapeutic effects on lead poisoning.
