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.

N-TENSE Topical combines the rainforest's most potent and powerful plants into one synergistic formula for topical use on the skin. These power plants have been independently documented around the world with anticancerous actions.* More information can also be found in the new Anti-Cancerous Guide

Ingredients: A herbal blend of sangre de grado, copaiba, graviola, espinheira santa, suma, pau d'arco, mullaca, vassourinha, and mutamba extracted in distilled water and alcohol. To prepare this natural remedy yourself: combine equal parts of graviola, espinheira santa, suma, pau d'arco, mullaca, vassourinha, and mutamba and make a tincture following the instructions on the Methods of Preparing Herbal Remedies page. To make a small amount... 1 part could be a tablespoon (you'd have 7 tablespoon of the blended herbal formula). Once the tincture is finished, measure it. For every 4 parts of the finished tincture, add one part sangre de grado resin and one part copaiba oil. Mix together and bottle it in a dark glass bottle (it will naturally separate... just shake well before using).

Suggested Use: Shake well and apply directly on the skin several times daily. Allow to dry completely before covering with clothing.

Contraindications: None reported

Drug Interactions: None known.

Other Observations: This extract will stain clothing and other textiles.

Vassourinha (Scoparia dulcis)
A crude extract of vassourinha was reported to be active against human oral epidermoid carcinoma cells (66% inhibition) in vitro.* Crude extracts from the plant demonstrated cytotoxicity towards six human stomach cancer cell lines.* These antitumor actions were linked to two phytochemicals, scopadulcic acid B and betulinic acid. These two chemicals have been documented with anticarcinomic, antimelanomic, cytotoxic, and antiviral properties in other research studies.*

Mutamba (Guazuma ulmifolia)
Mutamba, in one in vitro study, exhibited strong activity against human oral epidermoid carcinoma cells by inhibiting growth by 97.3%.* Mutamba also contains procyanidin B-2 which has shown in other in vitro studies to have antitumor activity.* In one study it showed activity towards melanoma cells with an ED50 of 1-4 mcg/ml.* Some of the latest research on mutamba has focused on the antioxidants in the plant and their ability to interfere with prostaglandin synthetase.*
