Raintree's guaco leaf powder (Mikania guaco) has been milled into a fine powder which is suitable to stuff into capsules or to prepare your own teas, tinctures or extracts. It has been sustainably wild-harvested in the Brazilian Amazon and it is rich in active and beneficial phytochemicals that occur naturally in this plant. Guaco is a significant source of the natural plant chemical, coumarin (as high as 11% in some guaco plants). Coumarin is used to produce the commonly used anticoagulant and blood thinning drug called coumadin.* Besides courmarin, other active plant chemicals in guaco include caffeolylquinic acids, cinnamic acid, glycosides, kaurenoic acids, germacran-olides, stigmasterol, tannins, and resins.*

Traditional Uses:* for upper respiratory problems (coughs, bronchitis, colds/flu, asthma, allergies, etc.); for various internal and external bacterial and protozoal infections; for Candida and yeast infections; for snakebite and insect bites and stings; as an analgesic (pain-reliever) and anti-inflammatory for arthritis, rheumatism, intestinal inflammation, and ulcers

Ingredients: 100% pure guaco leaf (Mikania guaco). No binders, fillers or additives are used. This product is non-irradiated and non-fumigated. It is a wild harvested product—grown naturally in the Brazilian Amazon without any pesticides or fertilizers.

Suggested Use: This plant is best prepared as an infusion (tea). Use one teaspoon of powder for each cup of water. Pour boiling water over herb in cup and allow to steep 10 minutes. Strain tea (or allow settled powder to remain in the bottom of cup) and drink warm. It is traditionally taken in 1/2 cup amounts, 3-4 times daily.

Contraindications: Guaco contains a significant amount of coumarin which is the plant chemical coumadin drugs are derived from. Coumarin/coudamin has an anti-coagulant and blood thinning effect and the use of guaco may demonstrate anticoagulant effects due to the coumarin content. Consult with your physician before taking this plant if you are taking coumadin drugs or if coumadin anticoagulant type drugs are contraindicated for your condition.

Drug Interactions: Will potentiate or enhance the effect of Warfarin® and other coumadin drugs.

Other Observations: In large dosages (three times or more the suggested use above) guaco has been reported to cause nausea, vomiting, and diarrhea.
