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 botanical formula which combines 7 plants traditionally used in South America for depression.* For more information on the individual ingredients in Amazon Mood Support, follow the links provided below to the plant database files in the Tropical Plant Database.

Ingredients: A proprietary blend of mulungu, muira puama, graviola, tayuya, damiana, passionflower, and chamomile. To prepare this natural remedy yourself: use two parts mulungu, muira puama and graviola 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 1.5 to 2 grams twice daily or as needed. (1 gram is approximately 1/2 teaspoon by volume)

Contraindications: Not to be used during pregnancy or while breast-feeding.

Drug Interactions: May enhance the effect of MAO-inhibitor and anxiolytic medications.

Other Practitioner Observations:
  • In some individuals this formula may cause drowsiness. If this interferes with daily work the dosage should be reduced.
  • Several plants in this formula have been documented to reduce blood pressure in animal studies. Individuals with low blood pressure should be monitored for this possible effect.

Mulungu (Erythrina mulungu, crista-galli)
Mulungu has demonstrated in 4 recent rat studies to possess effective anxiolytic actions and in another study it demonstrated sedative and CNS-depressant actions. In a 2006 study, mulungu was reported to increase memory and learning. In one of the studies on anxiolytic actions, the researchers reported that mulungu had an effect similar to the commonly-prescribed anti-anxiety drug, diazepam. Brazilian re-searchers reported in two 2007 animal studies that the anxiolytic action of mulungu could be atttributed to two erythravine chemicals found in the plant. In an earlier study, they suggested that these alkaloids may alter GABAergic neurotransmission. GABA (gamma-amino butyric acid) acts as a neurotransmitter in the brain; abnormalities with its function is implicated in diseases including epilepsy, anxiety, and depression. Researchers in 2012 attribute mulungu's anti-anxiety actions to an alkaloid chemical named erysothrine and continued to validate it's anti-anxiety action in animal studies.

Passionflower (Passiflora sp.)
Passionflower has long been used for stress and anxiety in many countries around the world. A good amount of research now supports these traditional uses, including some human studies. In a 2008 double-blind placebo clinical trial with patients undergoing surgery they concluded: "In outpatient surgery, administration of oral Passiflora incarnata as a premedication reduces anxiety without inducing sedation." A second human clinical study in 2012 with 60 surgical patients undergoing spinal anesthesia confirmed the same findings.

Chamomile (Matricaria chamomilla)
Chamomile is another plant with a long history of use for depression, stress and anxiety around the world. It has been documented with anti-anxiety, anti-stress and sedative effects in the research cited below. In one human randomized double-blind clinical study it was shown to be effective in treating mild to moderate anxiety.
