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.

Male Plus was developed exclusively for men and contains four powerful herbs from the Amazon rainforest including muira puama and catuaba—two unique rainforest plants that have been used for centuries in Brazil as male libido enhancers, male tonics, and supportive of male sexual organs, systems, and function.* To learn more about these wonderful rainforest plants, click on the plant names below to go to the Tropical Plant Database. Check out the new Discussion Forums to see if anyone is talking about how they are using this natural rainforest remedy.

Ingredients: A blend of muira puama, catuaba, huanarpo macho, and sarsaparilla extracted in distilled water and 40% ethanol. To prepare this natural remedy yourself: use three parts muira puama, two parts catuaba and two parts huanarpo macho and one part sarsparilla. To make a small amount... "1 part" could be one tablespoon (you'd have 8 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 and prepare a herbal tincture using the instructions on the Methods of Preparing Herbal Remedies page. Don't try to put this formula in capsules or prepare a tea with it. It will not be effective. Most of the active chemicals in muira puama are not soluble in water and must be extracted in alcohol.

Suggested Use: Take 60 drops (2 ml) in water twice daily or as desired.

Contraindications: None reported.

Drug Interactions: None reported.

Muira puama (Ptychopetalum olacoides)
In one French study among 262 male patients who experienced lack of sexual desire and the inability to attain or maintain an erection, 62% of the patients with loss of libido reported that muira puama "had a dynamic effect," and 51% of patients with erectile dysfunction felt that muira puama was beneficial.* The second study evaluated positive psychological benefits of muira puama in 100 men with male sexual weakness. In their final report, researchers indicated muira puama could "enhance libido [in 85% of the test group], increase the frequency of intercourse [in 100%] and improve the ability to maintain an erection [in 90%]."*

Catuaba (Erythroxylum catuaba)
According to Dr. Meira Penna, catuaba "functions as a stimulant of the nervous system, above all when one deals with functional impotence of the male genital organs. . . it is an innocent aphrodisiac, used without any ill effects at all."*

Huanarpo Macho (Jatropha macrantha)
Huanarpo macho is as popular in Peru as a male aphrodisiac as muira puama is in Brazil for the same purpose.* It is widely used in Peruvian herbal medicine systems to restore male sexual potency, for premature ejaculation, erectile dysfunction, and as a male sexual tonic and aphrodisiac.*

Sarsaparilla (Smilax officinalis, glabra)
Sarsaparilla is a rich source of phytosterols. It contains the plant steroids sarsasapogenin, smilagenin, sitosterol, stigmasterol, and pollinastanol; and the saponins sarsasaponin, smilasaponin, sarsaparilloside, and sitosterol glucoside, among others. The majority of sarsaparilla's pharmacological properties and actions have been attributed to these steroids and saponins. Sarsparilla is in this formula because many of these phytosterols aid in the gut-absorption and bioavailability of some of the other active chemicals in muira puama and catuaba which are harder to absorb.*
