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 7 plants which have been traditionally used to lower cholesterol levels.* 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 proprietary blend of artichoke, bitter melon, yerba mate, suma, vassourinha, pata de vaca, and sarsaparilla. To prepare this natural remedy yourself: Use three parts artichoke, two parts bitter melon 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 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 twice daily. (One gram is approximately 1 teaspoon by volume)

Contraindications:
  • Several of these ingredients contain plant saponins and/or phytosterols; as such this formula is contraindicated in hormone-positive cancers.
  • This formula contains yerba mate which has naturally occurring caffeine. Those allergic to or sensitive to caffeine should not use this formula.
Drug Interactions: May interact with MAO-inhibitors.

Other Practitioner Observations: Two ingredients in this formula have a hypoglycemic effect. Those with hypoglycemia should be monitored more closely for this possible effect.

Artichoke (Cynara scolymus)
A double-blind, randomized, placebo-controlled study was published in 2000 on artichoke leaf extract. For six weeks, 143 patients with high cholesterol were given artichoke; at the end of the test, results showed a decrease of 10%-15% in total cholesterol, low density lipoprotein (LDL), and ratio of LDL to HDL cholesterol. Scientists now report that the cholesterol-lowering effect of artichoke can be attributed to chemicals other than just cynarin, including several newly discovered ones. Another human study in 2008 re-confirmed artichoke's cholesterol lowering actions in the about the same decrease.

Bitter Melon (Momordica charantia)
Bitter melon has shown to lower cholesterol in many animal studies over the years. In one study, elevated cholesterol and triglyceride levels in diabetic rats were returned to normal after 10 weeks of treatment.

Suma (Pfaffia paniculata)
Suma root has a very high saponin content (up to 11%). In phytochemistry, plant saponins are well known to have a wide spectrum of activities including lowering blood cholesterol, inhibiting cancer cell growth, and acting as antifungal and antibacterial agents. Phytochemists report that saponins can act by binding with bile acids and cholesterol. It is thought that these chemicals "clean" or purge these fatty compounds from the body (thus lowering blood cholesterol levels).

Sarsaparilla (Smilax sp)
The majority of sarsaparilla's pharmacological properties and actions have been attributed to novel and known steroids and saponins. The saponins have been reported to facilitate the body's absorption of other drugs and phytochemicals, which accounts for its history of use in herbal formulas as an agent for bioavailability and to enhance the power and effect of other herbs.
