A synergistic formula of 6 rainforest botanicals which are traditionally used in South America for syphilis (a type of spirochete bacteria) and other bacterial conditions.* Lymes Disease is also caused by a similar spirochete bacteria.* This product was featured in an article by the Health Sciences Institute (see page 4).

For more information on the individual ingredients in the Spiro formula, follow the links provided below to the plant database files in the Tropical Plant Database.

Ingredients: A herbal blend of chanca piedra, bellaco caspi, tamamuri, matico, huacapu, and ajos sacha. To prepare this natural remedy yourself: use two parts chanca piedra 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 7 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 twice daily. (one gram is approximately 1/2 teaspoon by volume)

Contraindications: None reported.

Drug Interactions: None reported.

Other Practitioner Observations:
  • All of the plants in this formula have demonstrated antimicrobial effects in laboratory studies. Supplementing the diet with probiotics and digestive enzymes is advisable when this formula is used for longer than 30 days.*
