Ingredients: A proprietary blend of chanca piedra, boldo, erva tostão, cipó cabeludo, and abuta. To prepare this natural remedy yourself: Use 4 parts chanca peidra, two parts boldo, erva tostão, and cipó cabeludo and one part abuta. To make a small amount... "1 part" could be one tablespoon (you'd have 11 tablespoons of the blended herbal formula). For larger amounts, use "1 part" as one ounce or one cup or one pound. Combine all the herbs together well. The herbal mixture can then be stuffed into capsules or brewed into tea, stirred into juice or other liquid, or taken however you'd like.

Suggested Use: Take 1-2 grams three times daily. (1 gram is about 1/2 teaspoon by volume).

Contraindications: Not to be used during pregnancy or while breast-feeding.

Drug Interactions: May potentiate diabetic, heart, anticoagulant, and diuretic medications.

Other Practitioner Observations:
  • Several plants in this formula have been documented to reduce blood pressure and/or have a mild cardiac depressant effect in animal studies. Individuals with low blood pressure should be monitored for this possible effect.
  • Several plants in this formula contain coumarin which thins the blood. Those individuals with blood disorders such as hemophilia should be monitored closely for this possible effect.
  • Plants in this formula have a diuretic activity. Chronic long-term use of any diuretic can cause electrolyte and mineral imbalances which should be monitored more closely.

Chanca Piedra (Phyllanthus niruri)
In human studies, researchers reported that chanca promoted the elimination of stones and produced a significant increase in urine output as well as sodium and creatine excretion.* In in vitro and animal studies, researchers indicated that chanca piedra had the ability to block the formation of calcium oxalate crystals and prevent kidney stone formation.*
