Coriander (cilantro) has been proven to chelate toxic metals from our bodies in a relatively short period of time. Combined with the benefits of the other ingredients, this recipe is a powerful tissue cleanser. Two teaspoons of this pesto daily for three weeks is purportedly enough to increase the urinary excretion of mercury, lead and aluminum, thus effectively removing these toxic metals from our bodies. We can consider doing this cleanse for three weeks at least once a year. The pesto is delicious on toast, baked potatoes, and pasta.
