My boyfriend started using pysillium husks a few weeks ago to cleanse his intestinal tract. He felt great, but my God! his breath became so foul!! After a few days of being polite, I finally figured that I needed to say something and help him find a cure. I figured it had to have been caused by a change in his intestinal flora from the pysllium. The change must have caused severe candida overgrowth. His tongue was coated in white -- a sure sign. I had him take a few capsules of ParaGone (it was what was leftover in my medicine cabinet) to start to kill off the candida. That seemed to help, but didn't completely stop the halitosis. This is going to sound gross, but I made him open his mouth to detect whether the stench was coming from his breath, or from his teeth. I have particularly good smell and pinpointed that the smell was coming from the upper right side of his mouth! Well, after that I had him soak his mouth in straight hydrogen peroxide for about 3 minutes. Once it foamed up, I had him to it again. That was the cure! No more bad breath! The peroxide did make his tongue sensitive for a few days, so I would suggest to anyone trying this that they dilute the peroxide in water. I think that bad breath is often a sign of candida or yeast overgrowth so killing it in the mouth with peroxide AND taking some kind of candida cleanse is the answer. One more note: I read on the internet that it can take up to 3 weeks to cure bad breath. Well, this took a few minutes with the peroxide. Don't believe what you read! Hope this helps some of your readers. Thanks.

Just a note to the readers and especially to Sharon from NYC. One thing that psyllium does so very well is clean out the bowell. In doing this it also cleans out toxins that have been stored in all those little folds of your intestines. The coating on your boyfriend's tongue was more likely just a sign that his body was releasing toxins and not a sign of candida overgrowth. Bad breath can also a sign of toxins being released. They have to come out somehow. Drinking more water sometimes helps. I am glad to know about the peroxide mouth wash although I don't think it would be good to do very often. BTW, Psyllium promotes growth of good bacteria for the stomach & intestines. Another reason a Candida overgrowth was unlikely.

I had bad breath really terrible. I use 3% HP drug store for mouthwash twice a day. It works. I am reading on your site I should not use 3% drug store in my mouth. I do not swallow it and I rinse my mouth with fresh water after use of H2O2 to remove the thick foam. Is 3% drug store H2O2 dangerous to use as mouthwash?

H202 helps bad breath but after a while it comes back again. I think the bacteria becomes immune to it. what should you recommend.

That sounds like a post nasal drip issue. I have the same problem and this works for me:

Try using a Neti pot. It is a small pot you fill with lukewarm water and salt solution. It is used to flush out your nasal passages. Use it 1x - 2x daily to clean out the gunk collecting in the nasal/throat area. Definitely run a search on google and youtube to learn exactly how to use it. It's painless, all natural and definitely helps.

Also, with a tongue scraper, remove any white fuzz that collects at the back of your tongue. When gargling with peroxide (2 tsp of 3% peroxide with 2 tsp of water), tilt your head all the way back and stick out your tongue to ensure the nasty germs that dwell back there are killed. I would never swallow peroxide under any circumstances because I believe it's toxic.

Make sure you rinse & gargle with water thoroughly after.

I forgot to add one thing.

Make sure you brush, tongue scrape and Hydrogen Peroxide gargle after each meal for this to work (up to 4x daily as per instructions on HP bottle).

Let us know how this works for you!!

Hello all. I have always heard of people using chlorophyll for bad breath, I do not know if it will work for everyone... But alot of people believe it to have cured their bad breath. These are people that I know personally and not something I have read.

Get you some Clorophyll pills and give it a try.

Hope this helps someone!

I have had Bad Breath for as long as I can remember, I just recently tried Hydrogen Peroxide. OMG this has worked better than anything I have ever tried, and I have tried all sorts of stuff. I am using it 100% (thats how desperate I was) but will begin to dilute 50/50. Its hard to tell if you have bad breath unless its morning breath, and that is gone too! I am so glad I read this, I hope this is a permanent remedy. Only people who have had this problem can realize my excitement. Good Luck.

My BAD breath was not from the mouth but from the Nasal area. I suffered from very bad breath and the typical mouth-teeth treatment did not work.

I used a Neti Pot with Salt Water and a "small dash" of Hydrogen Peroxide to get rid of a sinus infection. A few weeks later my wife noticed my breath was OK. Thank God...

Important: use canning/pickling salt (no additives & cheap)

Something worked for me and I hope it will help those who suffer as well. All my life I looked into mouth thinking, it was teeth, I brushed till my teeth got erosions. I had no post nasal drip so I thought that is not the case for me. But when I swallowed, I always smelled that decay somewhere but still that no, I have dry nose and no I have no drip. But few days ago, I irrigated my nose using mix of water/h202 and brushed way back my tonsils! Keeping the electronic brush to the sides so I wont gag. BOY, MIRACLE. I DID THIS BEFORE BED AND NEXT MORNING. NOW FOUL TASTE OR BAD BREATH. NOT EVEN MORNING BREATH. SO IT WAS FROM NOSTRILS AND TONSILS. I HOPE YOU WILL GIVE IT A TRY!

I got lime juice and used a tongue scraper, WOW!! Usually when I brush my teeth and use mouth wash or use hydrogen peroxide, bad breath just comes back, even if I scrape my tongue. I am amazed by how well the lime juice is working!

Try a blotting tooth brush at least nightly. I use it while watching tv at night so it really doesn't take up any extra time.

Unlike others, my bad breath is caused by a sinus condition. The phlegm sits in the back of my throat causing bad breath. I was told to try magnesium which is supposed to break it up and makes the passageway clear. For me, it is the first thing to ever clear the throat. I then tried the hydrogen peroxide and no more bad breath. let me know how this works.

By chance we discovered that taking a teaspoon of manuka honey (not mixed with water) gets rid of bad breath for mum almost immediately. She has that problem on and off as she does not have the habit of drinking water. Well, we are glad that Manuka honey works for her all the time.

Lifelong ailments: Hi, I'm hoping I can get some clarity on my situation. I'm a 25 yr old female, and for as long as I can remember (pretty much all my life) I've suffered from bad breath and constipation. And I truly have no idea why. I have excellent dental hygeine, so I know that's not the culprit. No gingivitis or tonsil stones. I've never had the healthiest diet, but I feel like so many people eat horribly, and still don't have bad breath. Not to mention, I've had it since childhood. My mother also has bad breath, but she has dental issues, and her tongue isn't coated and gross like mine. I think I may have really slow digestion, because I can eat a piece of toast and sleep for 2 hours after. Digestive enzymes and apple cider vinegar don't help. I've tried every vitamin and supplement out there. I just don't understand. Everything I eat and drink stays on my tongue until I brush it again. Especially in the back middle of my tongue. It's pretty much made me a social outcast, and I've never really formed any intimate relationships because of my breath. I feel like doctors are so quick to get people in and out, they don't really look for the root cause. I'm not lactose intolerant or have a gluten allergy. I really don't know what could be causing this, but I'm at the end of my rope. I'm sorry this is so long.

Try coconut oil, eat it, brush with it, add a dab of baking soda and put a blob in your mouth before bed. Spit in trash in the morning... won't be long.

Hi Elizabeth: According to the book, Digestive Wellness (Lipski), if you have halitosis, you may want to do the following:

  • be checked for infections (H pylori, GERD, gastric ulcers)
  • eliminate constipation (which you mention you have) by increasing your fiber intake, make sure you are properly hydrated, exercise, take magnesium (most of us are deficient), take digestive enzymes, evaluate any medications you are taking which may cause constipation, take vitamin C
  • take a good probiotic
  • have your HCl levels checked (your food may be fermenting instead of digesting properly) by having your doctor run a comprehensive digestive stool analysis with parasitology evaluation

Perhaps a naturopath instead of a regular doctor might be what you need. In the meantime, the book I mentioned is really interesting and addresses all sorts of digestion problems. You even may be able to find it in your library. They do say that good health begins in the stomach. I hope you find the answers you are seeking. Good luck! Bess

Elizabeth: This looks like an obvious case of "dirty colon". This is usually the case of aged persons, but you must have undergone some kind of exception. Anyway, here's a link to remedy this condition.

Let us know how you're progressing.

Replied by Traveler

Do you use a tongue scraper? How often do you visit a dentist to clean your teeth and pockets? Have you tried an elimination diet, or a cleanse-- like master cleanser or a raw milk (if you have a reputable dairy nearby) cleanse?

Also, how many grams of fiber from whole foods are you getting, preferably from fruits and vegetables, not from bran or fiber powder? Is it at least 25grams or more? I noticed I would be very constipated for a long time because my average for many years was more around 9-15 grams a day, sometimes not even that. In terms of constipation, and menstrual issues, I was helped a lot by blackstrap molasses: 1-3 tablespoons a day in water normally, and the day before my period or during my period I would take 3 tablespoons two or three times a day.

Also, how much do you sweat? Maybe there's someting wrong with your lymph system and I could see how, having body odor you wouldn't want to emphasize that by sweating but that helps get out the funk and detox somewhat. So if you can encourage sweating with exercise, and also use epsom salts/baking soda (and ginger if you want) baths. Alternatively, you can do hot and cold showers which help the lymph system and the skin because it increases blood flow. It also helps with depression.

And, what type of deodorant are you using? I've been conventional-deodorant free for several years and have run the gamut of baking soda, white vinegar, apple cider vinegar, various alternative commercial deodorant. I've now been using perfume oils that are made with essential oils and I'm in LOVE with this stuff.

I have noticed that my bad breath doubles or triples with exercise. Running, weight training or even brisk walk for 15 odd minutes will boost the bacteria growth in my mouth. Taste in the mouth and the odor just gets worse and worse. I think it also shoots up a lil in the winters.

Spent countless dollars and still go through this hell every day. I think I have tried everything mentioned on this site, some work and some don't which is pretty normal. In the last 10 odd years I have travelled to all different corners of the globe and met different kinds of doctors. From Chinese traditional medicine to African witch craft doctors, from Muslim hakeems to Jewish Rabbis to Bible cures to Buddha meditation to Yoga, from Indian herbal medicine to acupuncture, acupressure, hypnotism therapy, traditional Japanese medicine, Arabic cures to Red Indian remedies, from meeting with old masters of Shaolin Temple to spending time with vegan Baba's of India, from Russian Babushka advice to Allopathic, Osteopathic to homeopathic to German medicine, world renown ENT, GI, and also to top ranked surgeons who completely removed my tonsils. But no permanent cure.

From what I have learned, there is NO CURE known to man for chronic bad breath or Halitosis. It's a genetic disorder and my only hope is that stem cell research will perhaps explore this avenue to finally find a cure. I am sure that will be long after we are gone from this world. (I usually envy and smile at folks who come up with the suggestions to keep a good oral hygiene, floss, diet, carbs, protein, lots of water, green foods, organic juices, good sleep, etc.. The only thought that runs into my mind at these times is, , , "You have NO IDEA what it is"

For now, I think we all just need each other's support and keep trying to treat the problem with different kinds of remedies that are ALL a temporary relief. Sometimes while driving to work, I smile and tell myself, "These are my happy pains".

There is a lot of talk here about 3% Hydrogen Peroxide, please be cautious that it does have side effects. It's abrasive but more importantly it's a poison. 1/2 HP and 1/2 H2O works for a couple of hours but I have yet to hear from any doctor who would recommend this for a long term use. Many dentists would not recommend the use for more than a week. Sometimes they even prescribe ONCE a week for 3 or 4 weeks and that's it. I used 50/50 ratio for a few weeks and got the burning sensation in the throat and nostrils till I got a throat infection. My mucous had blood and the doctors put me on antibiotics to kill the infection. I still use it with 1 and 5 ratio but I know no doctor will recommend it for long term use.

Personally, I will be jumping up and down with joy and happiness if I find any remedy that safely covers up the problem 100% for 4 hours and allows me to eat, drink and talk freely as anyone other person. I will gladly do it in the morning, after lunch and before the bed.

Have you tried a blotting toothbrush? I would recommend trying this daily to ensure clean teeth. It may take a few weeks to see more permanent results from this, but it is a fairly simple process. In addition, I would recommend oil pulling daily and brushing with activated charcoal and coconut oil. All fairly easy additions to your current routines. You can even use the blotting brush on your daily commute if you want to try to include it but don't have the extra time to really dedicate to the full process.

It's coming from your tongue. I suffer from bad breath since 1984. I very spent at least 20000 dollars. I had tonsillectomy, septum surgery, went see Dr spider in Australia., Dr Katz in California, Dr miller in virginia. Nothing helps. One day I decided to cure myself. I very noticed my tongue was always white. I bought a tongue brush and started to brush my tongue as hard I could for 5 minutes. My mouth was bloody but the pain was nothing compared to 30 years of embarrassment. I clean my mouth with warm water. Voila! My life changes from that moment. No more bad taste. I immediately went to the supermarket and started talking on the phone to see how people reacts. No reaction whatsoever. That was the first I ever talk to the cashier I even say thank you just to test my breath.

Once again it's your tongue. Don't use toothbrush. Use a tongue brush . You need to get rid of the white film. The bacterias live underneath.

Good luck.

I've had really bad breath for a decade and no one told me... Until my mother. I did a great deal of research on the subject. My Bad breath and gum disease is gone!

1. Buy: Organic coconut oil. Apple cider vinegar. Baking soda, peroxide and soft toothbrush.

2. In the morning, brush teeth with baking soda, then rise with baking soda and peroxide. I squirt a little peroxide into a 1/4 of water. I rinse for 2 minutes and spit it out. Then get a teaspoon of organic coconut oil and swish around your mouth for 10 to 15 minutes. This will pull toxins from your body and mouth.

3. Do all of this twice daily for a week or so. Your month will feel brand new and the stuff from under your gums will fallout and the gums will heal.

4. Drink two 8 ozs. glasses of water with one tablespoon of Apple Cider Vinegar. One early and one later in the day. This will further kill bacteria in the body.

5. Most importantly, change your diet. Eat organic fruits and veggies and green juices. Drop kick dairy, sugar, meat and processed foods. In three days you will feel brand new.

6. Take 5,000 units of D3 daily, Omega 6 and B12. You will become a new person... In less than a week. I guarantee.

Hope this helps!

I like many others on his site have suffered with bad breath for many many years, spent countless dollars on products for relief. I've suffered the humiliation of watching people's reaction when I speak. I've been to doctors and dentists to get help but nothing worked until I decided to attack the problem from three different angles- nasal, oral, and digestive.

Here's how I control it:

In the morning 20 minutes before eatting breakfast I take 3-4 Digestion Enzyme capsules. This aides in breaking down protein, milk, and other hard to digest foods that you eat thru out the day or food that might lay in your digestive track. Then I take 3-5 Probiotics with my breakfast. Purchase a bottle containing 12-15 billion cells per capsule with 8 or more different strains such as Lactobacillus and Bifidobacterium- read the label. I use Udo's Choice-Adult's Probiotic -$19. 99 from Whole Foods (or you can purchase on line. ) A lot of probiotic formulas only contain 1 billion cells per capsule this is not strong enough. This is the healthy bacteria found in yogurt. (Eatting small amounts of yogurt daily will not have the same effect you would have to eat a ton of yogurt). Probiotics loads the small & large intestines with healthy bacteria. Our chicken & dairy products are loaded with antibiotics that weaken the immune system killing good and bad bacteria. We are eatting antibiotics daily which is too much. Eventually the bad bacteria take over causing bad breath and other health problems. Everyone needs to take Probiotics daily even children.

The first morning after taking the Probiotic I noticed that my morning foul breath was gone. A little bad breath in the morning is natural. Most times bad breath comes from the digestive track from decayed undigested food and constipation. If you are constipated make a fruit smoothie in the morning. Leave a reply and I will give you an eazy recipe that I make every morning for myself!

Next I use my Netti Pot for my sinuses 3-5 times a week. I have Chronic Sinunitis. (If you don't have sinus trouble or tonsil stones you don't need to do this step). For the rest of us this helps clear up those smelly tonsil stones in the back of the throat. I use warm water with sea salt, a little baking soda and a few drops of Peroxide. I hope this helps you as much as it has helped me and I wanted to share. I hope this cures you too! Good health to you!

You may not believe this but has it occurred to you that your bad breath and chronic sinusitis are both related to a common problem which is overgrowth of bad bacterias in your stomach and intestine ? I suspect that you may also have white tongue (please correct me if I am wrong). Tell me if you do because that would exactly describe my condition.

Consuming probiotics is not a solution because if these good bacterias have to always be replenished then that means there are probably more bad bacterias than good ones in your digesting system. I found that you need to FEED these good bacterias with green leafy vegetables so that they can reproduce in your body and thus avoid always having to replenish them in large numbers. Instead of Enzymes you should consider HCL Betaine because this is the natural way to KILL bad bacterias while enzymes would only speed up the breakdown of food.

I can say that I had a severe case of bad bacteria overgrowth and finally I am slowly recovering from this mainly due to a healthier vegetable diet and of course my favorite, HCL Betaine. Artificial Enzymes are very expensive and it is really the HCL in your stomach that is responsible for stimulating your Pancreas to produce enzymes. By consuming Betaine HCL you are increasing your stomach acid and thus increasing the ability for your pancreas to secrete more enzymes naturally. For those with gall bladder issues, Betaine HCL also stimulates the liver to produce larger quantities of Bile that over time would thin out the THICK bile that is responsible for producing stones. This would serve to protect your gall bladders from the risk of accumulating and releasing large quantities of stones in the bile duct that can risk being fatal to your pancreas by blocking enzyme production.

Hi Janne, I have had bad breath (smells like crap) for at least 30 years and carry mints, cardamom and anything else with me. I was diagnosed with severe IBS as a youngster but basically I think I have horrible bacterial gut flora and have lots of decaying matter in my gut. Gums are not great but are only a small part of the problem. Have severe bloating and flatulence (worse than most cows) as well. I have turned vegetarian but eating carbs (which I have to as am a veggie and eat no meat etc) makes things worse. What I do remember is that when I did Atkins diet a few years ago bloating and flatulence stopped. If I drink milk my stomach goes for a six! I am going to try the high dose probiotics as well as HP remedy. Any other suggestions will be most welcome.
