This product is no longer sold by Raintree Nutrition, Inc. See the main product page for more information why. Try doing a google search or see the rainforest products page to find other companies selling rainforest herbal supplements or rainforest plants if you want to make this rainforest formula yourself.

A powerful formula of 8 rainforest botanicals which have been traditionally used in South America for arthritis, and muscle and joint pain, strains, and injuries.* For more information on the individual ingredients in Amazon Joint-Muscle Support, follow the links provided below to the plant database files in the Tropical Plant Database.

Ingredients: A herbal blend of cat's claw, chuchuhuasi, amor seco, tayuya, picão preto, iporuru, sarsaparilla, and guaco. To prepare this natural remedy yourself: Use 2 parts cat's claw and one part of each of the remaining plants listed. To make a small amount... "1 part" could be one tablespoon (you'd have 9 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 1/2 grams by weight (or 1 1/2 to 1 teaspoon by volume) every 4-6 hours as needed.

  • Not to be used during pregnancy or while breast-feeding.
  • Several plants in this formula contain coumarin which has an anticoagulant effect. Individuals with blood disorders such as hemophilia, or those on blood thinning medications should be monitored for this effect.
  • This product should not be used with medications intended to suppress the immune system.
Drug Interactions: May potentiate anticoagulants such as Warfarin®. May reduce the effect of immune suppressive medications. May enhance the effect of antihypertensive medications.

Other Practitioner Observations:
  • Picão preto contains a small amount of naturally occurring caffeine. Those individuals sensitive or allergic to caffeine should avoid this formula.
  • Cat's claw has been documented to have an anti-fertility effect. Those seeking to become pregnant or those undergoing treatment for infertility should consult their doctor prior to use.
