I woke up with a sinus infection on Thursday and suffered through the day on Dayquil. Friday morning, I drank 2 tbs of ACV in 8 oz of water. That helped a little bit. I found this website and read posts about GSE, oil pulling and the neti pot. I went to Whole Foods for the neti pot and GSE. Friday afternoon and evening, the neti pot helped ease sinus pressure and prompted drainage. This morning Saturday, I woke up and did oil pulling. Then, I added 4 drops of GSE to the neti pot (8 oz water with 1/4 tsp salt). I used this combo-one for each nostril.
Right now, I feel great. My sinus pressure is gone and my congestion is rapidly draining as I type this post. I am pretty sure combining the GSE with the neti pot treatment did the trick and I will continue this for at least five days to cure my sinus infection. Good luck and be peaceful!

Amazing! I regularly suffer from sinus infections and had been using apple cider vinegar in warm water to treat it. This time it was just not doing the trick. I tried 4 drops of grapefruit seed extract in my neti pot this evening, and just 3 hours later I am feeling the release of pressure and drainage. I have my fingers crossed for the futher improvement over the next few days with continued treatment - but already I am impressed!

I also had a great experience with grapefruit seed extract. At work a girl came in sick (thanks pal) sore throat, very bad, and flu type ailments. Sure enough we all got it, my throat was not just sore, it felt like it was swollen. Maybe glands, my ears hurt down into my neck. After 2 days of getting worse, I started grapefruit seed extract. 10 drops 4 times a day, after the first day I felt a little better. I put it in warm water and drank it. This was very soothing to the throat. After two full days I was almost all better, I did continue four days, six days total

My coworkers who just let it pass naturally were sick for two weeks, some longer. I really think this stuff helped me, next time I will use it at the onset of an illness.

I just wanted to share my story as well. I became ill when my son contracted viral meningitis on a trip. Traveling back in the car, I could only take lots of EmergenC. For the next few days, I took the EmergenC with GAIA Echinacea three times a day and got lots of rest. It seemed to work after four days, so I stopped the treatments. Well I think I got a secondary infection because my lymph nodes became swollen and my sinuses became infected. I irrigated my nose with grapefruit seed extract (diluted) but some undiluted liquid got in my right sinus and caused a lot of pain. Discouraged and about to go to the doctor for antibiotics, I come across your wonderful website. I first started back on the C & Echinacea but added the Grapefruit seed extract (5 drops in 12 oz water). My sinuses were cured in one day! That same day I drank 12 oz of water with 3 tbsp. of ACV. The next day the affected area was in my throat. I made warm ACV with lemon (3 tbsp) and honey (2tbsp) and drank as much as I could. The day after that I felt I only had laryngitis. So I found Ted's wonderful receipe for Green Tea with baking soda (1/4 tsp). I have done this for two mornings and feel almost back to normal. Thanks to all your contributors, I am cured in a matter of a few days! You guys are awesome, especially Ted.

I just wanted to say that I have been taking grapefruit extract in tablet form for years whenever I get a cold or sinus infection. I take 2 little tablets three times a day for about a week and on the third day, I always feel better. Colds do not go into sinus infections if I take it and if I do get a sinus infection (like I did recently from swimming in the ocean), it goes away within a couple of days when I take the tablets. If I don't tke them, I stay miserable. I had a naturalpathic doctor tell me it was okay to take them for as long as a month at a time, but I never need to. They always make me feel better, so I take them anytime I feel a little under the weather and it always works. My husband does the same thing and it works for him too. The tablets are small and easy to get down. No bad side effects for us, only good effects.

I have been reading your website and have been especially interested in your sinus remedies. I have been trying acv and grapefruit seed extract. I have been battling sinus infections since September have been on about 5 courses of antibotics. I am on antibotics right now because when I went to the ENT docter he said I have a sinus infection. What I find strange is I never get a runny nose I just get a lot of pain in my teeth pressure on the side of my nose and headache and I feel allergic to everything. Anyway was wondering I notice I started getting the sinus infections when I started taking these diets products that are soy based. Do you think there is a connection ? I feel that the grape fruit seed extract and acv are working the only thing that I notice is about 2 hours after I take the grape fruit seed extract I feel alot of chest congestion then I get this dry cought for a bit. I think its the grape fruit seed extract working. I am looking into the candida possibilities.

20 years ago, I had chronic sinus infections that no doctor could explain. I went to a nutritionist who prescribed Grapefruit Seed Extract for yeast buildup. I started doing a sinus rinse with it and cured the infections. I haven't had one since. GLORY! Cathy

A safer option for people who are interested in using Grapefruit Seed Extract (GSE) in their nose is Xlear Nasal Spray (XNS) which contains purified water, xylitol, GSE and sodium chloride.

The GSE is a potent antimicrobial and has antibiofilm effects. The xylitol also has antibiofilm effects while cleansing and moisturizing at the same time to offset the drying effects of the saline solution. XNS has been around for a long time and is made in safe proportions of ingredients. Here is a link to the product on Amazon, but XNS is available at many drug stores :
