Amazon Sinus Support was a formula of rainforest botanicals which have been traditionally used in South America for allergies and sinusitis.* For more information on the individual ingredients in Amazon Sinus Support, follow the links provided below to the plant database files in the Tropical Plant Database.

Ingredients: An herbal blend of nettle leaf, carqueja, gerv‚o, pic„o preto, yerba mate, jatoba, pau d'arco, and guaco. To prepare this natural remedy yourself: use 3 parts nettle leaf (don't use nettle root... it isn't the same), 2 parts carqueja, and one part each of gerv‚o, pic„o preto, yerba mate, jatoba, pau d'arco, and guaco. 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 by weight (or about 1/2 to 1 teaspoon by volume) every 4-6 hours as needed.

Contraindications: None reported.

Drug Interactions: None reported.

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.
  • Yerba mate contains naturally occurring caffeine. Those sensitive to or allergic to caffeine should avoid this formula.
  • Gerv‚o contains a small quantity of salicylic acid. Those allergic to aspirin or salicylic acid should not take this formula.
