A synergistic formula of 8 rainforest botanicals traditionally used in South America for balding and hair loss.* For more information on the individual ingredients in Amazon Hair Support, follow the links provided below to the plant database files in the Tropical Plant Database.

Ingredients: A herbal blend of avenca, muira puama, nettle root, chuchuhuasi, catuaba, mutamba, gervβo, and sarsaparilla. To prepare this natural remedy yourself: use 2 parts nettle root, 2 parts muira puama, 2 parts mutamba, and one part each of the remaining herbs in the list. 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) twice daily or take 1 teaspoon (by volume) twice daily.

Contraindications: Not to be used during pregnancy, while breast-feeding or while seeking to become pregnant.

Drug Interactions: May enhance the effects of antihypertensive medications.

Other Practitioner Observations:
  • Several ingredients have been documented to reduce blood pressure in animal studies. Those with low blood pressure should be monitored more closely for this possible effect.
  • This formulation may increase body hair, including facial hair.
