A botanical formula which combines 8 plants used by the shamans of the rainforest and herbal practitioners in South America for male vigor, libido, and as specific tonics for men.* For more information on the individual ingredients in Amazon M-T-Tonic, follow the links provided below to the plant database files in the Tropical Plant Database.

Ingredients: A herbal blend of muira puama, maca, suma, sarsaparilla, catuaba, chuchuhuasi, nettle, and jatoba. To prepare this natural remedy yourself: use two parts muira puama, two parts maca, 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)

Contraindications: None.

Drug Interactions: May enhance the effect of high blood pressure medications.

Other Practitioner Observations: Several plants in this formula have been documented to reduce blood pressure. Individuals with low blood pressure should be monitored for this possible effect.
