Larrea tridentata, also called Chaparral and "Shegoi", is a desert plant that has been shown throughout Native-American tradition and medical history to produce significant positive immune assistance and help with pain. 

The historical use of the plant prompted a research and development process that has led to important discoveries about larrea.

Additionally, published research performed at several well-known medical research institutions, such as the Stanford University School of Medicine1, the University of Berne (Switzerland), The Johns Hopkins University2, and King's College London, have demonstrated that chemical compounds present in the larrea plant do possess health-enhancing properties.

People with various immune challenges have sought out larrea.


More About Larrea

Larrea tridentata is a shrub, also known as chaparral and "creosote bush", that is indigenous to deserts of the southwestern United States and parts of Mexico. It has been used by many people with various conditions.

The extremely bitter taste of the larrea leaves prevents animals from grazing upon it, and it does not burn easily. It is regarded as one of the most adaptable of all the United States desert plants as it grows in depleted soil and can survive for long periods of time without rainfall.


Other Names For Larrea -- "Chaparral" and "Shegoi"

Native American Indians of the southwest named the larrea plant "Shegoi", meaning "Mother of all plants". They long ago discovered this helpful resource and used it for many conditions from respiratory ailments to arthritis. It was revered as their most important medicinal herb, calling it their "Medicine Chest".

This plant plays a prominent role in the creation stories of the Pima tribe.  They believe that Larrea was the first plant placed on the Earth by the creator, shortly after the planet itself was created.

As it turns out, modern science has, in a way, confirmed the legend of the Pimas. Recently, it has been verified that Larrea is indeed among the oldest living plants in the world.  Some currently living Larrea plants actually started growing about 12,000 years ago, shortly after the glaciers retreated during the last ice age.

Also known as chaparral, the larrea plant has perfectly adapted to survive for many thousands of years in severe conditions that can greatly challenge the survival of a human within just hours. Larrea thrives in desert regions such as Death Valley, the Mojave Desert, the Sonoran Desert and other harsh, dry areas in the southwest U.S. 


History and Scientific Development

Larrea Tridentata is the botanical designation of the creosote bush or chaparral. It is a plant that is indigenous to the southwestern United States and northern Mexico. It has been a common health aid among native Americans of the southwest for thousands of years.
Scientific analysis has revealed beneficial phytochemicals in the larrea tridentata herb. These compounds include powerful antioxidants that enhance the body's natural defenses and a substance that assists in combating invaders of the body.

The fact this waxy-leaved bush can thrive in the harsh desert and dominate its neighbors without being eaten or infected is testimonial to the potency of its chemical arsenal.

This desert chaparral plant indeed has something that we can use for better health. Research has identified dozens of special antioxidant lignans and flavonoids in chaparral. They also discovered a powerful antioxidant called NDGA.

"The chaparral (Larrea tridentata) that grows over hundreds of square miles in Arizona and California contains a powerful antioxidant called NDGA (nordihydroguaiaretic acid). NDGA was used to prevent oxidation from spoiling foods during World War II. . . . Chaparral also contains polysaccharides, which stimulate the immune system."

Tested and Used By Physicians and Athletes
Larrea products have been offered to patients by holistic oriented doctors for the great benefits and relief it can bring. Also a number of sports teams have utilized larrea as an anti-inflammatory for players.
Vitamin C Enhances Effectiveness
It is recommended that vitamin C be taken with larrea for better results. Vitamin C has been shown to improve the benefits from larrea. The combined antioxidants help prevent free radical damage from invaders and toxins.
(NOTE: The larrea extract capsules are made with an appropriate amount of vitamin C in them for this purpose.)
How Much & How Long
It would be better to start with just one capsule of larrea, whether the raw herb or the extract, for the first day or two to test whether there will be a cleansing reaction.
If there is an active issue to deal with, up to 4 capsules per day can be taken for a while to get a jump on improvement. Then reduce to 2 capsules per day. 
Concern About The Liver
After allegations in 1992 of liver toxicity associated with chaparral larrea consumption, manufacturers voluntarily restricted sales until the reports were investigated. Following a lengthy review, a panel of medical experts concluded "no clinical data was found . . . to indicate chaparral is inherently a hepatic toxin." In late 1994 this report was submitted to the FDA and the product was subsequently given a clean bill of health.
After comparing the quantity of chaparral consumed each year to the number of product complaints, industry regulators concluded chaparral does not pose a significant threat to consumer safety.
Nonetheless, the raw unprocessed chaparral larrea has some compounds in it that could accumulate in the body with excessive use, causing the liver to work harder. We suggest that every six to eight weeks users take a break of a week or so from consuming the raw larrea. It would also be wise to utilize other herbs for cleansing as well as antioxidants and foods that support the liver.
The American Herbal Products Association (AHPA), recommends the following statement be put on all chaparral product labels:

"Seek advice from a health practitioner before use if you have had, or may have had liver disease. Discontinue use if nausea, fever, fatigue, or jaundice occurs."

A major advantage of the larrea extract is that these potential irritant compounds have been removed.


Comparison Of Unprocessed Chaparral Larrea With Larrea Extract
Larrea, or chaparral, has been used for thousands of years by native Americans and many others, which is an indication of its effectiveness.

Larreastat was the trade name for the patented extract of larrea tridentata. (This extract was originally called "Virastatin" and later changed to "Larreastat".)

We had sold that product for about 14 years, ever since it was marketed to the public, but it has not been available for several years. The patent owner had repeated difficulties getting the LarreaRx products manufactured properly.

At long last a replacement for the original formerly patented larrea extract is NOW AVAILABLE!

The extract is concentrated, and some compounds that are potentially irritating with long term use of the raw herb are eliminated in preparing the extract.

A definitive comparison of the raw whole chaparral larrea herb with the extract has never been conducted. A "rule of thumb" for quantity would be about 2 or 3 capsules of chaparral larrea in place of 1 capsule of the concentrated extract.

People have taken 4 to 6 capsules per day of raw chaparral larrea, or 2 to 3 capsules of extract (spread through the day) for several days if needed. It is suggested that vitamin C be taken with the raw chaparral larrea to enhance effectiveness.

(NOTE: The former Penetrating Spray as well as the Cold Sore Lotion are still not available.)

For combating bothersome microbes, it is also suggested you consider our advanced silver products, invader fighting herbs, oregano oil and other immune support.

It is a concentrated extract of pure, clean, high quality larrea tridentata with irritant compounds removed from the raw herb by special processes.

Each capsule contains 200 mg. of larrea extract and 180 mg. of vitamin C (ascorbic acid from calcium ascorbate), which enhances effectiveness of compounds in the herb.

The recommended usage is 2 capsules per day, although more could be take for a while if dealing with an urgent challenge.

$50 per bottle

plus $5.95 per order for postage



IMPORTANT NOTE: At the start of taking either the raw larrea or the extract, it is recommended to use just one capsule the first day or two to test for a cleansing reaction. There could be a feeling of discomfort or other signs of waste materials being eliminated.

If there is such a result, it is considered advisable by those in the know to consume plenty of water and a mild diet, perhaps also using a strong probiotic supplement, a silver supplement, and other herbs and supplements.
