This product is no longer sold by Raintree Nutrition, Inc. See the main product page for more information why. Try doing a google search or see the rainforest products page to find other companies selling rainforest herbal supplements or rainforest plants if you want to make this rainforest formula yourself.

A botanical formula which combines 7 plants traditionally used in South America for asthma, COPD and other lung problems* For more information on the individual ingredients in Amazon Lung Support, follow the links provided below to the plant database files in the Tropical Plant Database.

Ingredients: A herbal blend of amor seco, embauba, avenca, mullaca, jatoba, mutamba, and samambaia. To prepare this natural remedy yourself: use three parts amor seco, two parts embauba, and one part each of the remaining plants 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 to 1.5 grams 2-3 times daily. (1 gram is approximately 1 teaspoon by volume)

  • Not to be used during pregnancy or while breast-feeding.
  • This formula should not be used in combination with digitalis.
  • Those with cardiac disorders should be monitored more closely when taking this formula.
Drug Interactions: None reported; however, based on animal studies, it may potentiate digitalis, ACE-inhibitor, hypoglycemic, and hypotensive drugs.

Other Practitioner Observations:
  • Several plants in this formula have been documented to reduce blood pressure in animal studies. Individuals with low blood pressure should be monitored for this possible effect.
  • Several ingredients have shown a hypoglycemic effect in animal studies. Those with hypoglycemia should monitor their blood sugar levels for this possible effect.
