Supplementation of garlic conferring 1.2mg of allicin thrice daily to workers in a car battery plant was able to reduce symptoms of lead toxicity after four weeks, while the reference drug (D-penicillamine) failed to do so. Both D-penicillamine (24%) and garlic (19%) were equivalent in reducing lead accumulation in the blood.
