GSE stops Bacteria, Fungi, Candida Yeast, Parasites, and More.

Grapefruit seed extract (GSE) is being used to kill bacteria like Strep, Staph, Salmonella, E. Coli, and also to fight Candida, Herpes, Influenza, parasites, fungi and traveler's diarrhea. This has been proven in laboratories all over the world, and is supported by feedback from doctors, veterinarians, farmers and consumers. Non-toxic, biodegradable, economical, with no harmful side-effects.

Discovered in 1972 by Dr. Jacob Harish, a physicist, GSE has been used all over the world for the better health of people, plants and animals. Grapefruit extract is used as an antibiotic, antiseptic, disinfectant, and as a preservative in food and cosmetics. GSE is also non-toxic, environmentally safe, and quickly bio-degradable. It causes no side effects and is often dramatically less expensive than existing treatments or chemicals for similiar applications, whether human, animal, or agricultural in scope.

How was GSE Discovered?

grapefruitJacob Harish was eating a grapefruit for breakfast one morning in France and savoring its taste.

World War II had just ended and since fresh fruit was a rare treat in Europe at that time, Jacob savored it all the more - until, that is, he bit into a seed! The extremely bitter taste of the seed interrupted his enjoyment of breakfast but also prompted him to wonder, 'What makes it so bitter?'

For many, such a question would have been of mere passing interest, but for Jacob, a budding scientist, it inspired a compelling inquiry, one that would take decades to answer and years more to 'bear fruit'.

Jacob Harich was born in Yugoslavia in 1919 and educated in Germany. WWII interrupted his studies in nuclear physics. After witnessing the horrors of war as a fighter pilot, young Harich was inspired to devote the rest of his life to improving the human condition. To this end, he augmented his studies in physics with a full university course in medicine, specializing in gynecology and immunology. Arriving in the United States in 1957, Dr. Harich furthered his education at Long Island University, N.Y. But it wasn't until 1963, after moving to the heart of grapefruit country in Florida, that he received the necessary support to carry out his research.

Harich approached Dr. Steven Otwell and Dr. Wayne Marshall, both leading researchers on the effects of microbes on food. Although initially skeptical, they were won over by the demonstration of GSE's amazing ability to protect produce, fish, and poultry from the assault of bacteria, fungi, and parasites. The reputation of these two doctors and the renown of the food science laboratory at the University of Florida, Gainesville, their home base, prompted other institutions to consider the claims being made by Dr. Harich.

Finally, by 1990, holistic health practitioners in the United States began to hear about this remarkable product, understand the implications for their patients, and thereby gave Dr. Harich's work the boost it deserved into scientific credibility.

In 1995 Dr. Harich was invited to Europe as a guest of honor of the Pasteur Institute of France, Europe's leading AIDS research center. For several years the Institute has been researching the potential of GSE as a prophylactic against the HIV virus as well as against some of the secondary infections associated with AIDS. He was also honored by farmers in Europe who now use a powdered form of GSE in fish and poultry feed to fight two potentially lethal bacteria, Salmonella and E. Coli.

Dr. Harich died in May of 1996. It is pleasant to think that he did receive in his lifetime the recognition he deserved for a life devoted to a revolutionary approach to controlling dangerous germs.


University of Georgia Evaluates GSE

grapefruit Testing was conducted by the University of Georgia, in Athens, GA, to evaluate GSE as a disinfectant in tests against E. Coli, Salmonella sps., and Staph aureus. Roger Wyatt, Ph.D., and Microbiologist for the University of GA, reported, "Our studies indicate excellent potential for these products(GSE). ...The toxicological that I have reviewed indicated that this product and the active ingredient poses very low toxicity. As you know this is important because most disinfectants that are currently used in either animal or human environments have moderate to high toxicity and extreme care must be exercised when these products are used. The lack of any significant toxicological properties of (GSE) is also impressive when one views the efficacy data where extemely small concentrations of the product can be used with marked beneficial results."

Dr. Wyatt continued, "In view of the reports that we have discussed, the wide spectrum of activity that (GSE) offers(antiviral, antibacterial; Gram+ and Gram-, antimycotic, and antiprotozoan) will undoubtedly aid in its acceptability." Dr. Wyatt's findings have also been confirmed by a variety of clinics and labs, as well as universities from around the world, including the University of Arkansas, the University of Malaya, the U. of Sao Paulo, and the University Ricardo Palma, to name a few.


Germ-Killing Skin Cleanser Touted by University of Sao Paulo

grapefruitNot since hexachlorophene has anything been such a powerful germ killer and deep cleanser. Fortunately for us, GSE when mixed with soap and cleansing products only kills the germs, not the skin or the environment. Its efficacy is corroborated by Dr. J. A. Rotino of the University of Sao Paulo in Brazil. Dr. Botino was testing GSE against alcohol in emergency field prep situations and reported, "... (GSE) was 100% effective(at 100 ppm) in skin disinfection when used as a pre-surgical prep compared to 72% effective for alcohol."

Dr. Botino also found that GSE was "...100%(effective at 100 ppm) as compared to 98% for commercially available surgical soap" when used as a pre-surgical scrub for l minute.

A growing number of dermatologists, aestheticians and cosmetologists are now using GSE mixed in soaps, skin cleansers or as a direct treatment itself, to cleanse, purify, and balance facial skin and other areas of the body.

As a super facial cleanser aestheticians apply 2-3 drops of GSE to their moistened fingertips and gently massage the wetted facial area in circular motions for about a minute, rinsing thoroughly with cool water. Patients often report a tingling sensation of the skin following the treatment which is indicative of the cleansing action and bacteria-killing properties of the GSE.


Enjoy Your Holiday!

grapefruitUp until now, about the only way you could avoid the awful race to the bathroom while traveling abroad was to boil or chlorinate everything you ate or drank, and sterilize all utensils. Even those extremes could be for naught if you inadvertantly moistened your toothbrush with tapwater. GSE has proven to be an exceptional, and simple alternative!

Doctors recommend as little as one or two drops in a glass of water each day as a preventative for "Traveler's Diarrhea" aka "Montezuma's Revenge". It is also used as a curative as reported by Dr. C. W. Lynn, M.D., of Orlando, Florida. He reports that while traveling in South America, a patient and traveling companion suffered severe diarrhea three days after eating way-side strawberries en route from Argentina to Churin. Dr. Lynn prescribed two drops in a glass of water at noon and once again at bedtime.

Dr. Lynn's Clinical Investigational Form reports that the next morning, the patient "...was down to breakfast and eating. No further bowel problem."

In another trip to Mexico and South America, Dr. Lynn traveled with a group of 38 patients ages 10 - 68 years both male and female. Half of the group took 1 drop of GSE daily while the other half did not. Of those taking the GSE "...not one acquired diarrhea", while the other half suffered.


First Aid for Drinking Water

grapefruitGSE is ideal as a safe and simple way to disinfect drinking water when camping, back packing or in any emergency situation where safe drinking water is not obtainable, and boiling(or distilling) is not practical.

Available water should first be filtered. (At the very least, let suspended particles settle.) Retain the clear water and add 10 to 25 drops of GSE (less for questionable tap water, more for stream or pond water) for each one gallon of water. Shake or stir vigorously and let sit for a few minutes. A slightly bitter taste may be noticed. This is just the inherent taste of the GSE.

Safe and easy to carry!

A word on humidifiers: Put 3 or 4 drops GSE per gallon of reservoir water into your humidifier, and voila! The slimy algae will not grow! This will work whenever standing water is present. Safe and non-toxic. 


Stops sore throat, Kills Strep!

grapefruitSuch a simple remedy for a problem that is usually candy-coated instead of cured.

Gargling with GSE and water will handle the most resistant Strep germs. The necessary dilution of GSE against Streptococcus faecalis is only 1:80,000, in vitro. In vivo, doctors are recommending gargling with 2 to 3 drops in 5 ounces of water. This gives an effective and potent dilution ratio of about 300 - 500 ppm. (For small children, mix one or two drops into any palatable heavy syrup, which will slow the product as it goes down the throat, and conceal the bitter taste, which kids don't like.)

Unlike many currently marketed products for sore throat pain, after gargling with GSE, it is completely healthful to swallow the solution.


"When my son came home from school, he looked terrible. He said his throat was killing him. work for a few hours, but when he came home, he said he already felt better! After 2 more days of gargling and swallowing GSE in water, he was fully recovered and full of energy!"
- D. M., Vermont


"The next major advance in the health of the American people will be determined by what the individual is willing to do for himself."

grapefruit Dr. Jay Gordon, M.D.: Candida diaper rash and thrush stopped

January 30, 1996

The Townsend Letter
To the Editor: I am writing to you because I know that your readers are always interested in new and better ways to treat patient's problems. Like most other pediatricians and family physicians, I have seen many children with candida diaper rashes and oral monillasis. Treating rashes and thrush with nystatin preparations is not always successful and many parents strongly object when they read the label and see what I've asked them to put into their baby's mouth three times each day for a week or two or more. I began using GSE about five years ago after a mother in my practice told me about her success in using an extremely dilute(a few drops to three or four ounces of water) solution to treat a yeast infection in her baby. the results were wonderful and the families in my practice were very happy to listen to a much more natural suggestion for curing this very common problem. The parents are very pleased to be using a product which is not only more naturally derived but is also free of the additives found in nystatin products; they are tired of all the artificial colors and sweeteners. My first experience was with a thirteen-month-old baby who had transferred to my practice after multiple courses of antibiotics to treat an ear infection. The otitis media was finally in remission, but the bright red candidiasis in the diaper area was causing as much distress to the infant and her parents as had the ear infections. I recommended that they add five drops of GSE to four ounces of water and leave it on the changing table to wash the baby's bottom as part of each diaper change. A miraculous overnight cure did not occur, but within a few days the rash was receding and infection was gone within another week. A second similar adventure with a two-year-old boy convinced me that I was onto something. I have used the same dilute solution to treat refractory diaper rashes and oral yeast infections in many children and I'll continue to look for new uses for what I regard as an innocuous, natural antimicrobial. I have found this weak citrus solution to be completely safe for even the very youngest babies in my practice. (I once tried putting an undiluted drop on my own tongue and learned a valuable lesson which I pass on to all the parents about taking great care in diluting the extract.) ...I now recommend it(GSE) at least three or four times each day for fungal and minor bacterial infections...

Sincerely,
Jay N. Gordon, M.D.

GSE Saves Peru's Alpacas

grapefruit

This test was conducted by Dr. Guillermo Calderon, Associate Professor of Immunology at the University of San Marcos in Lima, Peru. Five hundred and sixty baby alpacas ranging in age from 2 - 6 weeks were divided into five different groups, two receiving placebos, two receiving alternative medications, and one group receiving 400 ppm doses of GSE, 1 dose daily for three days. Dr. Fernando Scheelje of Interfab, S.A., reports, "For many years decreases in alpaca have been difficult to cope with. Enterotoxemia, colibacilosis, and enteritis are the major infectious problem in baby alpacas. Vaccines and antibiotic treatment have proven to have different and non-stable results." The tests conducted by Dr. Calderon indicate that GSE "...at 400ppm given orally, out-performed competitive drugs and reduced the average death rate from over 50% to less than 2%."

In conclusion, Dr. Scheelje wrote that GSE "gave a promising solution for a traditional problem in two ways: (A.) Preventative, and (B.) Curative."


A New AntiViral

grapefruit

In laboratory tests conducted by Southern Research Institute and reported by William M. Shannon, Ph.D., head of the Microbiology-Virology Division, GSE "...was effective in inactivating HSV-1 (herpes symplex virus type 1) after a 10 minute exposure at a 1:256 dilutions." Against human influenza virus type A2/Aichi/2/68 in vitro, the MIC(minimum inhibitory concentration) for GSE was the same, 1:256. Dr. Shannon reported, "The fact that GSE effectively inactivated both HSV-1 and influenza A virus suggests that an EPA type viricidal assay might demonstrate significant efficacy for this product." In South America, Interlan, S.A. reports that GSE has been tested effective against the measles virus. The United States Dept. of Agriculture tested GSE and found it effective against four animal viruses: Foot and Mouth Disease, African Swine fever, Swine Vesicular Disease, and Avian influenza.

As to exactly what the viricidal possibilities are for GSE, only time will tell. We do know that it has been acclaimed effective in the aforementioned applications, and off the record, we have heard reports from many people who claim GSE has cured or dramatically lessened symptoms of even the common cold and flu viruses. So, given its efficacy as an antiprotozoan, we will be closely watching for evidence of GSE's effectiveness against these molecular parasites. 


Poison Oak and Ivy, Warts and Dermatitis

grapefruit

Many forms of dermatitis, poison oak, poison ivy, cysts and other skin disorders are being effectively treated with GSE. The healing antibacterial, antifungal, antiviral effects of this product seem to promote the healing of almost any atypical skin condition. Applying GSE topically, we have had reports of cysts dissolving with only a few treatments, stubborn warts removed with only a few applications, and poison oak and ivy almost miraculously healed, sometimes overnight. The recommended application for most skin disorders is to mix GSE at about a 1% concentration (alternatively, with other essential oils like chamomile and tea tree), and applying from a spray bottle, leaving on the skin. Alternatively, 2 to 3 drops can be applied by fingertip to the wetted affected area, leaving on for a few minutes, then rinsing thoroughly with cool water.

An even more concentrated application is often needed for cysts and warts, with doctors recommending direct application of a single drop on the cyst or wart and covering with a bandaid after the GSE is allowed to be absorbed.
