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 combination of rainforest plants which have been traditionally used to support memory and brain function.* For more information on the individual ingredients in Amazon Blood Support, follow the links provided below to the plant database files in the Tropical Plant Database. More information can also be found in the Organ-Specific Guide.

Ingredients: A herbal blend of samambaia, calaguala, tamamuri, catuaba, muira puama, cat's claw, suma, guarana, nettle, and sarsaparilla. To prepare this natural remedy yourself: Use three parts samambaia, three parts calaguala, two parts muira puama and one part each of the remaining plants shown in the list above. To make a small amount... "1 part" could be one tablespoon (you'd have 15 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 2 grams by weight (or about 1 teaspoon by volume) two to three times daily, or as directed by a healthcare professional.

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

Drug Interactions: None known.

Please refer to the plant database files by clicking on the plant names below to see all available documentation and research on each plant ingredient.

Samambaia & Calaguala (Polypodium decumanum & Polypodium leucotomos)
Samambaia and calaguala are closely related Polypodium ferns which have demonstrated neuropro-tective actions. In 1997, a U.S. patent was filed on a samambaia extract capable of treating brain dis-orders such as Alzheimer's disease and dementia. The patent and several in vivo clinical studies indicate samambaia protects against brain cell degeneration, promotes repair of damaged brain cells, and has a protective effect to brain cells. In a double-blind placebo human trial in 2000, researchers reported patients with senile dementia improved cognitive performance, increased the blood supply to the brain, and also increased the electrical impulses in the brain. A calaguala patented product called anapsos is now used in Spain and Europe for the treatment of Alzheimer's and dementia.

Guaraná is the subject of 6 human and animal studies concerning memory enhancement and cognitive performance. In a 2007 double-blind, placebo-controlled, multi-dose human evaluation study, guaraná improved secondary memory performance and increased alert and content mood ratings. Lower doses (75 mg) produced more positive cognitive effects than higher doses.

Sarsaparilla (Smilax sp)
Sarsaparilla, and several of its chemical constituents, were reported to provide protection of amyloid beta protein-induced neurotoxicity in several recent studies in rats. One of sarsparilla's main sapogenin chemicals, sarsasapogenin, was reported to improve memory by elevating the low muscarinic acetylcholine receptor density in brains of memory-deficit rats. This chemical, as well as others in sarsaparilla, are the subject of a 2004 U.S. patent which claim they are effective in the treatment of Alzheimer's disease. Sarsaparilla and/or it's plant chemicals have documented anti-depressant. memory enhancements and anti-Alzheimer's actions in the following studies.
