A synergistic formula of 8 rainforest botanicals traditionally used in South America for hypertension.* For more information on the individual ingredients in Amazon Heart Support, follow the links provided below to the plant database files in the Tropical Plant Database.
Ingredients: A proprietary blend of Brazilian peppertree, abuta, chanca piedra, picão preto, erva tostão, mulungu, graviola, and mutamba. To prepare this natural remedy yourself: use two parts abuta, two parts Brazilian peppertree and 1 part each of the remaining herbs in the list. To make a small amount... "1 part" could be one tablespoon (you'd have 10 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 (by weight) twice daily or 1/2 to 1 teaspoon (by volume) twice daily.
Contraindications: Not to be used during pregnancy or while breast-feeding.
Drug Interactions: May enhance the effect of diuretic, ACE-inhibitor, antihypertensive and cardiac depressant medications.
Other Practitioner Observations:
- Plants in this formula have been documented to reduce blood pressure. This product is contraindicated for persons with low blood pressure.
