Here is a pesto recipe that is used for oral chelation of mercury. It is also delicious.
1 clove garlic
1/2 cup almonds or other nuts
1 cup packed fresh cilantro leaves
2 TBLS. Lemon juice
6 TBLS. Olive oil
Put the cilantro and olive oil in blender and blend until cilantro is chopped. Add the rest of the ingredients and process to a lumpy paste. (You may need to add a touch of hot water and scrape the sides of the blender.) You can change the consistency by altering the amount of olive oil and lemon juice, but keep the 3:1 ratio of the oil and lemon juice. This freezes well if you want to make several batches.
It is recommended a couple of teaspoons a day for two or three weeks, once or twice a year.
