Grapefruit Seed Extract Rx for Cold and Flu Season

I’ve got some good news and some bad news…

Good news is that during the Fall/Winter months, our thoughts turn to holiday gatherings and events when we get to see family and friends.

The bad news is that with the children back in school, the increase in indoor activities, and the participation in holiday festivities, there is such an increase in illness, we now define five seasons: Spring, Summer, Fall, Winter, and “Cold and Flu Season”.

A Must-Have For Every Home During Cold and Flu Season

How to Defend You and Your Family During Cold and Flu Season with Grapefruit Seed Extract

Sometimes, you may find that every time you turn around, a child or spouse has picked up a virus and passes it on to the next family member. This is certainly the case when children are in school, or your family is involved in more public activities. More exposure to public areas means more exposure to germs.

Of course, it’s not just exposure that encourages the proliferation of viruses. Also, there are the simple carbs and sugary treats that accompany holidays or special celebrations. Consumption of these goodies is almost a requirement, without regard to the burden placed on the immune system and increased susceptibility to the next passing virus.

Whether it’s a sore throat, earache, viral infection, intestinal problem, or anything else related to a virus, fungus, or bad bacteria, if you are the main caregiver in your home, Grapefruit Seed Extract is a must-have for your cupboard.

Do not confuse Grapefruit Seed Extract with Grape Seed Extract – though both are healthy – it is “Grapefruit” Seed Extract (abbreviated as GSE or GFSE) that works as a natural antibiotic with anti-viral, anti-bacterial, and anti-fungal properties.

GSE extract is derived by using crushed grapefruit seeds and the pulp. There are a few brands available at health food stores, and it’s sold in liquid, tablets or capsule forms. Usually, 10 drops of liquid is similar in strength to 1 capsule (125 mg).

The liquid (somewhat bitter flavor) can be used easily for a variety of benefits – internal and external. It has a slightly bitter taste and is highly acidic – 2.2 – which is why you should always dilute the liquid before using.

Liquid GSE can be diluted in water or juice, or you may purchase empty capsules and put the drops in a capsule each time you take a dose.

GSE capsules can be the handiest for swallowing since they come already prepared for swallowing. However, whichever form you use for internal purposes, be sure you start with a lower dose for the first few days, and slowly increase to your tolerance level – no more than the maximum recommended daily amount.

Award-winning and internationally recognized internist, Dr. Leo Galland, M.D. has used GSE extensively and found that, “GSE can be administered for weeks or months…. Immunosuppressed patients taking the preparation for over a year (have had) no apparent development of side effects….”

Listed below are a variety of ways to use GSE for you and your family’s health.

Internal Uses:

Fight Colds, Flus, Viruses

Reach for the GSE at the first symptoms of flu or cold.

For children under 10, use no more than 3 to 5 drops of GSE in 5 ounces of juice, up to 3 times a day.

For adults, take 10 to 15 drops of GSE in 5 ounces of water or juice, up to 3 times a day.

Or, you can also mix up to 50 drops in a quart of water/juice to be consumed through the day.

If you prefer, take two capsules or tablets, three times a day. Continue to take a couple of days beyond when the symptoms disappear to be sure the “bad guys” are being well-controlled by your immune system.

Sore Throat

For the onset of a sore throat, dilute 3 drops of GSE in about 5 ounces of water and gargle for several minutes. Spit out the liquid and do not swallow.

This can be repeated every couple of hours.

GSE may even help fight Strep germs when in the beginning stages. However, if symptoms continue to get worse, see your healthcare provider.

For simplicity, commercially prepared Throat Sprays Throat Sprays containing GSE can be purchased.


For an earache, commercially prepared Ear DropsEar Drops are available at health food stores or online.

However, if you prefer to make your own, mix 3 to 4 drops of liquid GSE into 1 ounce of vegetable glycerin.

Put a few drops in the infected ear.

Cover with a warm cloth or heating pad.

Be careful to dilute and mix very well to avoid irritating the sensitive lining of the ear.

Repeat every few hours until the earache is gone.

This use may be combined with internal GSE consumption, for double protection.

Sinus Infections

Mix 2 ounces of saline water (1/4 teaspoon salt with 8 ounces distilled water – NOT “tap” water) with 1 to 2 drops of GSE, and use in each nostril.

Then, tilt head forward toward floor in an upside down position.

This allows the GSE mixture to reach the sinus passages.

This may sting a bit depending on how much the sinuses are irritated.

With tissues handy, after a minute or two, return to an upright position – allowing the sinuses to drain.

Do not sniff or inhale through the nose, but instead allow the liquid to drain well from the sinus cavity.

Start with a low concentration of GSE to know what your sinuses will tolerate.

If the dosage is too mild, slowly increase each time with a maximum of 20 drops of GSE in 8 ounces of distilled water, to be used every few hours – approximately 3 to 4 times per day until symptoms have cleared.

This mixture is not for young children.

There are commercial Nose SpraysNose Sprays with GSE available online, or at health food stores.

Gums and Gingivitis

As a mouth rinse, dilute 5 to 10 drops of GSE in 6 to 8 ounces of water.

Rinse thoroughly for 10 seconds, once or twice a day, and spit.

Do not swallow the solution.

You can also clean your toothbrush by soaking it for 15 minutes or more in a similar mixture of 5 to 10 drops to a glass of water.

Rinse brush afterwards.

Candida and Intestinal Microflora Imbalance

An overgrowth of Candida or general imbalance of all microflora in the intestines (aka: Dysbiosis) can cause a long list of temporary to chronic health problems.

More information on the dangers and treatment of Candida can be found here.

GSE is highly effective at rebalancing and differentiating between the “good” microflora (bacteria) and the bad.

By destroying the bad bacteria, fungus, and pathogens, the good bacteria has a stronger opportunity to do its work and keep you healthy.

Your body will also have a much stronger resistance to stomach and intestinal ailments.

Suffice it to say, the more balanced the microflora, the healthier you will be.

Start slow with GSE, perhaps one capsule (125 mg) or ten drops twice to three times each day. If needed, you may decide to increase your dosage of GSE to between 600 – 750 mg a day.

More Intestinal Concerns

Since GSE has components that provide broad-spectrum benefits for the intestines and promotes a healthy environment for balanced microflora, it is reasonable that it can help as a preventative or in situations of intestinal distress:

  • Traveler’s Diarrhea – As a preventative when traveling in areas with questionable water, mix 1 or 2 drops GSE in each glass of water, or on your toothbrush to disinfect and help prevent Traveler’s diarrhea.
  • Diarrhea – If you do experience a case of diarrhea, take 15 to 25 drops GSE every 3 to 4 hours in water or juice – no more than 75 drops per day. Or, 2 capsules/tablets (no more than 6 per day) every 4 hours.
  • Parasites – Affecting a significant number of adults in various ways, parasites can become more of a concern when traveling where the opportunity for food and water contamination increases. Use the same amount of GSE as for diarrhea, with possibly increasing to a maximum of 5 doses per day. Be sure to consult a healthcare professional if the condition does not show improvement within a few days. Parasites take longer to destroy – sometimes, many months – so be patient with your body and be committed to staying on track with the treatment.


There have been anecdotal reports of GSE helping some serious illnesses, such as Chronic Fatigue Syndrome, AIDS, and even Cancer. If GSE is used for these type of diseases, please start very slow and only under the supervision of your health care provider.

External Uses:

Cold sores, Cuts, Wounds

As a highly effective anti-bacterial agent, frequent applications of GSE on sores and cuts may help promote faster healing.

When Dr. J.A. Botino (University of Sao Paulo, Brazil) tested GSE in comparison to alcohol for disinfecting, he discovered that GSE was 100% effective (at 100 ppm) for disinfecting skin in preparation for surgery.

Alcohol was 72% effective and surgical soap showed 98% effectiveness, in contrast.

For simple cuts, wounds or cold sores, dilute 1 to 5 drops of GSE in 50 drops of purified water and apply with spray bottle or cotton ball.


GSE can be used to cleanse the face by adding 2 or 3 drops to your face cleanser. Remember, it is imperative that you avoid contact with the eyes (it stings!) when using GSE on the face.

The bacteria-killing and cleaning properties of GSE may cause a tingling feeling for a few minutes. If too much tingling, dilute with water.

For an internal cleanse (or natural antibiotic) to help fight acne, dilute 10 to 15 drops of liquid GSE in water/juice (or take 1 to 2 capsules/tablets), and consume 3 times a day.


Add a few drops into your hand (with your shampoo) and mix before applying on your scalp. Massage into scalp for at least 2 minutes, and then rinse. Always rinse with plenty of water if you should accidently get GSE in your eyes.

Household Uses: 


Using 10 to 15 drops in the final rinse water can help kill fungus, bacteria, and viruses.

Household cleaners

Add 15 to 20 drops to a bottle of your favorite natural cleaning product (or vinegar and water) to help disinfect cutting boards, and other kitchen or bathroom surfaces.

GSE can be effective at killing most pathogens, such as staph, strep, or salmonella.

Nebulizers and Humidifiers

In a nebulizer, put 1 drop GSE for every ounce of saline water to help prevent or control respiratory infections. For a humidifier, use 3 to 4 drops per gallon of water to prevent algae growth.


GSE has been used as a natural preservative and may be more effective than some chemical preservatives on the market. This may explain the extended shelf life of GSE, whereas batches that are more than six years old have tested as strong as a new batch.

Some farmers have had success with using GSE in animal feed and water to reduce the spreading of infectious diseases.

There are reports that adding GSE to hot tubs and swimming pools have lessened the need for high levels of chlorine, though no dilution ratio could be found.

Drug Interactions:

For internal use, some pharmaceuticals – including birth control pills – interact with grapefruit (the fruit and juice) as it increases the absorption rate of certain drugs. Though GSE is not known to have demonstrated similar interactions, if you are on any medications, please be sure to check with your healthcare provider prior to consuming GSE.


There are many more uses for GSE. Once you have successfully used it for something simple, like fighting a cold, you may find yourself reaching for it, regularly, whenever you find a need for  its anti-viral, anti-fungal, and anti-bacterial properties.
