According to WebMD, 37 million Americans suffer from at least one episode of sinusitis each year. Sinus troubles leave many struggling for weeks and months on end. Stuffy and congested nose, pain between the eyes or in the forehead and upper teeth ache, are just some of the irritating and painful symptoms of a sinus infection. But there is a natural cure for sinus infection: grapefruit seed extract (GSE) is an extremely potent natural remedy that can effectively fight sinus infections.


From my own personal experience, I know that sinus infections can be truly debilitating and I’ve written a number of articles on how to beat sinus infection: the best home remedies for sinus infection and how to use horseradish to treat sinus infection. I believe that if you want to beat a sinus infection, it’s best to combine different types of treatments. In this article I want to describe how I virtually solved my chronic sinus infection using grape fruit seed extract (GSE).

Grapefruit seed extract (GSE), which is made from the pulp and the seeds of the grapefruit, acts as a natural antibiotic. It has antioxidant, antibacterial and antiviral properties and is a very versatile natural remedy. The grapefruit’s high vitamin C content and other healing nutrients help the body defeat infection and relieve congestion. GSE is considered to be an effective way to deal with sinusitis and has long lasting results.

I’ve used grapefruit seed extract when I had sinus infection that lasted a few weeks and I had great results. Within days I’ve noticed an amazing improvement: the pressure that I had in my sinuses has disappeared and I was able to breath properly through my nose. I found out that many other people had great experience when using GSE to treat their sinus infection.


What Can You Expect From GSE?

  • It’s antibacterial and antiviral but it doesn’t harm beneficial intestinal flora in the intestines.
  • It’s natural and safe and doesn’t contain any potentially harmful chemicals.
  • Unlike some other treatments, it doesn’t dry and dehydrate the body.
  • It stabilizes the body’s pH, which has an overall positive effect on the body and aids disease prevention.
  • It works as a natural antiseptic.
  • It’s easy to use.
  • It provides the body with some additional nutrients that support health and well-being.

How to Use Grapefruit Seed Extract to Treat Sinus Infections

You can take GSE in different forms: you can irrigate the nasal passages, take it in a capsule or tablet form or drink it mixed with water (or other fluid).

Based on my own experience, the most effective way to use GSE for sinus infection is to irrigate your sinuses using saline water mixed with a few drops of GSE. You should always mix the GSE with water as it’s extremely concentrated and it may burn and irritate your sinuses if it’s too concentrated.

How to Irrigate Your Sinuses With GSE

Mix a few drops of GSE with ¼ teaspoon of salt in a glass of warm water (240ml  / 8 fl oz). You should NEVER use tap water for your sinus irrigation – use bottled water that has been distilled or sterilized, or previously boiled and cooled down water to make sure it is free from bacteria. Use the mixture to irrigate the nasal cavities – this is best done by using a sinus rinse bottle or a neti pot.


For those unfamiliar with a neti pot, this is a ceramic or plastic pot that has been used for centuries in Ayurvedic medicine. It acts as a container and is designed to rinse debris or mucus from your nasal cavity. The other option is to use a squeeze bottle (this is what I’ve used) and I found it very easy to use. You can find more information about the type of bottle I’ve used (including an image) in my post about the best home remedies for sinus infection.


When using GSE for the first time, start with only one drop to see how your body reacts to the GSE and this would also allow you to get used to the smell and taste of GSE as it’s quite bitter. You can gradually increase the number of GSE drops you mix with your saline water. I’ve used 6 drops and I believe that this is the maximum that you should use. I’ve experimented with more than 6 drops but I found out that it started to irritate my sinuses.

I’ve washed my sinuses 3 times per day for a period of one week. It shouldn’t irritate your sinuses and it shouldn’t burn but it does have a certain bitter taste and smell. But don’t worry, you get used to the taste and smell quickly and after a few washes you won’t notice the taste or the smell.

Drink GSE Mixed With Water

Another option is to use GSE mixed with water (you can also use juice) – I’ve mixed 20 drops of GSE with half a glass of water and drank it 3 time a day. You should always start with just a few drops to see how your body reacts and then gradually increase the number of GSE drops you put in the water. Your GSE may be more concentrated than mine so you may need to put a smaller number of drops and you should have the instructions on your GSE bottle.

Allergic Reactions To GSE

In rare cases, there have been reports of an allergy to GSE. The allergic reaction will usually present with rash, facial swelling, lightheadedness or a drop in blood pressure. If you experience such symptoms, you need to contact a doctor immediately.

Most people, however, report excellent results with no side effects, and the benefits of GSE can usually be observed very soon after taking the extract.

I am curious to know if you’ve used GSE in the past and what was your experience – please leave your message in the comments below.

    I am a very long time sufferer of allergies that often manifest in sinus infections. I missed work and spent a great deal of money on OTC’s and or Rx’s from a physician. I currently am oxygen dependent because of COPD and sinus issues are segue for hospitalization for worse infections.

    About six months ago, I discovered Xylitol. Since then I have not been troubled with respiratory or sinus difficulties, and am not as stressed with COPD as well.

    I recommend you consider this as a suggestion in your letters.

    I use the nasal spray and the mints. I cannot use the gum, I have dentures. I would if I could and my grandson is chewing the gum now each day to prevent tooth decay.

    Xylitol is the best to come along for my family and I. Pass it on please?

    In EU we used Citrosept made in Sveden. Very good result on infected sinuses and fungal ,bacterial infection.I practiced with my patients few years ago../thank you for post Thank you

  4. Kim says:

    I had a terrible sinus infection for a couple of months back in November. I have completly lost my sense of smell & taste. Took two rounds of antibiotics to feel better then doctor tried a third round to try to get my taste & smell back, which did not help. Has anyone experienced this?

    • Petra Kues says:

      Yes, I have. A roaring sinus infection!
      I had sinus surgery twice (ethmoidectomy) and I had used GSE for years to keep my sinuses clear of infection. Recently I had a very bad cold with a roaring sinus infection – Dr gave Rx Ceftin but there was still that horrible yellow discharge. So I used a couple of drops more of GSE than usual…(3 in all)
      BAD MISTAKE! I thought my sinuses were on fire. Re- rinsed with plain salt water (Dr. Neil) without much difference.
      Now several days later, infection gone – but so is my sense of small and taste. Will that come back?

      • Jenny says:

        Hi Petra, I am sorry to hear about your sinus infection. GSE is extremely strong and potent and every person reacts differently to GSE – I was okay with 6 drops but everyone is different. This is why I mentioned that one needs to gradually add more drops to the water rinse bottle. You mentioned that you are okay now but did you try horseradish? you can read about it in my post on How To Use Horseradish For Sinus Infections also make sure to read my other post about sinus infection: The Best Home Remedies For Sinus Infection. It took me quite a while to recover from my sinus infection and even now my nose feels partially blocked. The doctors can’t really explain what’s the reason for that. I sure hope that you will get your sense of smell back but if you have any concerns it’s best to see your doctor. All the best!

  5. Valarie Gregory says:

    Thank you for your post. People, like myself, that take certain prescription medications cannot drink grapefruit juice. Would GSE have the same effect as the juice? I would love to be able to use it for my sinusitis.

    • Jenny says:

      Hi Valarie, I’ve seen in Livestrong website that grapefruit seed extract can impair your body’s ability to absorb certain medications and can interfere with them (see more information here). You should definitely consult with a doctor before taking it.

  6. Laura says:

    I used GSE in a netipot for a recurring sinus infection that I had previously taken steroids and antibiotics to get rid of….it came back a week after I finished the antibiotics so I went to the healthfood store and bought GSE extract to put in my neti pot. Results were amazing and it truly got rid of the infection. The infection was so bad I could smell it in my nasal passages, didn’t think anything was going to work. My dad caught also came down with the bug I had caught and the day that he did, I told him to go get GSE. His symptoms only lasted a day and never got to an infection. From now on, I will always know how to prevent this from happening again.

  7. Dawn says:

    I had an awful sinus infection and nothing seemed to work. I got NutriBiotic’s Nasal Spray Grapefruit Seed Extract. Took it three times a day and the very next day I started to feel better. It’s not too expensive and it’s very easy to use. My son also has problems with chronic sinus infections and I started him on a spray up each nose once a day and he hasn’t gotten an infection since he started.

    • Sue Ann says:

      Hello, i am perusing through remedies for sinus infections and saw that you responded about a year ago. Was curious to know how the grapefruit seed nasal spray has been effective over the course of a year with you and your son. Seriously considering it. Thanks so much for your help.

  9. Joanne says:

    I have sinus issues and found an opened 2 oz. bottle of ADVANTAGE Liquid concentrate WISDOM OF THE AGES in my medicine cabinet, but no expiration date – wondering if this stuff lasts forever??? Thanks!

  10. Melissa says:

    To drink it, you’re supposed to mix 10 drops with juice, 1 to 3 times a day (that’s what mine says to do) , but it doesn’t say, for how many days to do this… help?

  11. Tina says:

    I’ve been using YL essential grapefruit oil for 6 weeks in my water all day long. I had rotator cuff surgery and slacked on the water with the oil. Got a sinus infection! Started back with water and Grapefruit oil now for three days and am starting to feel much better. I also use YL R.C., Thieves, and Peppermint together and inhale it out if my hands after I rub it on my chest and temples. I also diffuse R.C. and peppermint!! Sleeping like a baby! Oils work and are awesome!!

  12. Deb says:

    I have found that if you mix a few drops of GSE in black coffee, it counteracts the bitterness and isn’t quite so bad. I usually use a teeny dixie cup and mix the coffee a with 10-12 drops and down it and then chase it with regular coffee, or juice. I still have my sinus infection and I’m sure I need to be more persistent. Fairly certain it’s a fungus since antibiotics did’t do anything. Trying to stay off the surgeons table. Been there…done that with BOTH sides.

    • Michael D says:

      You probably should irrigate your sinuses with gse and a bit of salt in a Neti Potti to get better results as it would get straight to the problem area . I had serious sinus issues which eventually resulted in perpetual bleeding . Not even normal salt an bicarbonate of soda in a netti potti helped . But 3 days after using gse , bleeding virtually all stopped and now I am on the recovery path .Still use gse twice daily to continue healing . Benefits are my sinuses are no longer swollen , blocked and I can breath again after months .. And I have stopped snoring .. my wife is delighted !

  13. Rachel says:

    I’ve been using nutribiotic gse nasal spray for a month and I’ve been able to stop using be conservation, which is great. One thing I’m getting though is as soon as I spray I sneeze anything from 15 mins to 1/2 hour sometimes. Would you know what causes it.

    • Jenny Hills says:

      Hi Rachel, I’ve seen other people complain about this issue in several forums, but I couldn’t find an answer from an authority source. I’m thinking maybe it’s allergic reaction to GSE but I cannot be really sure. You may wish to try using another nasal spray that doesn’t contain GSE and see if you have the same response or not.
