"An aphthous ulcer (aka canker sore) is a type of oral ulcer which presents as a painful open sore inside the mouth or upper throat, caused by a break in the mucous membrane. The condition is also known as aphthous stomatitis, and alternatively as "Sutton's Disease," especially in the case of multiple or recurring ulcers.

The term aphtha means ulcer; it has been used for many years to describe areas of ulceration on mucous membranes. Aphthous stomatitis is a condition which is characterized by recurrent discrete areas of ulceration which are almost always painful. Recurrent aphthous stomatitis (RAS) can be distinguished from other diseases with similar-appearing oral lesions, such as certain viral exanthems or Herpes simplex, by their tendency to recur, and their multiplicity and chronicity. Recurrent aphthous stomatitis is one of the most common oral conditions. At least 10% of the population suffers from it. Women are more often affected than men. About 30-40% of patients with recurrent aphthae report a family history." (Wikipedia)

ALUM

[BETTER BUT WITH SIDE EFFECTS]  11/12/2009: Liz from Hudson Valley, New York writes: "I had a canker sore that was at the peak of inflammation and pain and I decided to try putting Alum on it last night as recommended here to stop the pain. I bought the crystallized kind from the spice section of the grocery store and licked my finger, dabbed it it the alum and then dabbed it on the sore and let it sit/dry/sink in for 5 minutes.

OH MY GOD - it hurt like nobody's business which I could tolerate, but then for the next hour it made my entire jaw, neck and ear area throb with terrible pain which I could not tolerate. I ended up taking pain relievers and going to bed several hours early just to stop the pain with sleep. I have not been in such agonizing pain for many years. It felt like a migraine and an earache and a toothache all at once.

However, today my canker sore has been very tender but noticeably less painful (i've also been on pain meds all day because I'm a bit scarred by what happened last night). The sore also seems to be healing. I honestly am not sure if I can recommend the alum or not, given the positive effects today and the horrible effects last night."

[SIDE EFFECTS]  10/09/2009: Kathleen from Newport Beach, Ca writes: "Ok! When I'm stressed I bite the inside of my mouth. Yuck!! I know! This can lead to the MOTHER of all canker sores. My dear friend just told me to dab alum into the canker sore, hold the affected area out so it can settle into canker sore and not be washed away by saliva. Let me explain. What I have going is a flipping cluster of sores( 12 in total. SERIOUSLY!!) A few are about 1/4 x 3/8. No I'm not joking. So I apply the alum out of desperation. I'm in constant pain, my lips aren't working. Drool is running down my chin(SEXY right?) AND i CAN'T eat. Ok the alum feels like flipping battery ACID. I want to rip half my face off. Who cares that it tastes viley bitter-it REALLY hurts. It does not sting. Serious PAIN. After about 20 minutes half my lower jaw is numb. Thank God!!! It feels a little swollen. I look in the mirror and honest to God it looks like I've just had half of my mouth pumped up with whatever that crap is that make you look like a freak of nature! I live in newport beach-the land of the plastic fantastic. Please tell me that this will subside and I won't look like a middle aged woman having a midlife crisis and a budget to only cover half the job! Frickin' Y-I-K-E-S !!!!!!!!"



[SIDE EFFECTS]  11/07/2009: Man0fsteel from Redondo Beach, Ca, USA replies: "Okay, so I get canker sores every so often, esp. when I don't get enough sleep. This particular monster sore on my lower lip started when I severely bit into my lower lip TWICE on the same spot a week ago. No signs of healing. And they usually do after a week. Not this one. So someone suggested Alum. A quick search online brings me here where there is a lot of positive feedback. So I put the Alum on and like the above post, the pain is pretty intense. Tears are leaking involuntarily out of my eyes. 5 minutes go by and I rinse it off. It's now about 30 min after and the sore feels like it's twice the previous size. Totally swollen. And it's throbbing like no tomorrow. If it gets better, I'll be shocked, but I will report if it does in the morning."


11/07/2009: Alice from Shingle Springs, Ca, U.S.A. replies: "Smashing up a lysine (a particular amino acid) tab and making a paste with water and applying it to the sore is reported to relieve it. Totally non-toxic."

[WARNING!]  01/18/2009: Sid from Salmon Arm, BC, Canada writes: "Alum is a form of aluminum. Oral injestion of aluminum can cause canker sores. Do you really want to do that? The reason it works may be the same reason that the mercuric ointment my mom used to put on my rashes ( I later found out that I was mercury toxic) got rid of my rash. Apparently, it makes it go deeper into your body, thereby getting rid of the eruption on the surface."

EC: More about this here: http://www.ochef.com/1080.htm



02/14/2009: Chris from St louis, MO replies: "Alum has nothing to do with alumnium; how on earth do you labor under that delusion?"

EC: Best answer we could find on the alum used in cooking:

http://www.ochef.com/1080.htm

"Alum is a salt that in chemistry is a combination of an alkali metal, such as sodium, potassium, or ammonium and a trivalent metal, such as aluminum, iron, or chromium. The most common form, potassium aluminum sulfate, or potash alum, is one form that has been used in food processing. Another, sodium aluminum sulfate, is an ingredient in commercially produced baking powder. (Have you never noticed the faint metallic taste in baking powder? It comes from the alum.)

The potassium-based alum has been used to produce crisp cucumber and watermelon-rind pickles as well as maraschino cherries, where the aluminum ions strengthen the fruits' cell-wall pectins.

Alum is approved by the U.S. Food and Drug Administration as a food additive, but in large quantities — well, an ounce or more — it is toxic to humans. As a result, efforts have been made and are being made to wean us of our alum dependency. The U.S. Department of Agriculture says that if good quality produce and modern canning methods are employed, there is no need to use alum to bolster the crispness of our pickles and cherries. In any event, t"he department says, even if alum is used to soak the pickles, it should not be used in the final pickling liquid.



06/01/2009: Dan from Grand Rapids, MI replies: "The reason alum works is that it is an astringent, not because it forces anything into your body."

[YEA]  10/06/2008: Saskia from Takoma Park, MD, USA writes: "I had started taking apple cider vinegar twice a day, and after two days noticed the beginning of a canker sore. It didn't hurt yet, so I checked this site, then went out and got some Alum in the grocery store. I did as someone else suggested and wetted my finger, then dipped it into the alum, and then held it on the canker sore for about 5 minutes. Because I caught my canker sore so early, it didn't really sting at all.

I did that twice the first day, and again twice on the second day. It never hurt at all, and it got a little larger at first, but then started receding, and now 4 days later, its basically gone! I'm so happy with the Alum cure! I used to spend a whole week in agony thinking there was no way to help it- I love this website!"

[YEA]  08/09/2008: Cblhris from Bloomington, IN writes: "I am apparently one of those peoplt that are particularly susceptible to canker sores. I have tried many remedies, but the best by far is the alum. It stings a bit of first, but after one application the canker sore pain is gone. After two, the lesion is gone. Having used it dozens of times, I can say that if you don't mind the sting, alum is the only way to go!!"

Good ol Mom! Not sure where you can get alum because mine is from 1965 and it still works and still tastes terrible! Hope this helps someone."

I researched online and it seemed there was no cure or relief. I stumbled upon this website and I am happy to say with a combination of alum crystals rubbed gently on the sores followed by a light paste of aspirin, literally within 4 hrs the cankers no longer hurt and they are subsiding. Yeah! I highly recommend this combo."

My wires would always split the canker in two AS it grows, so whenever I open my mouth it pulls on the canker. I put alum in it and the next day it had completely decreased in size and no longer hurt. After two days it was completely gone!"

[YEA]  08/11/2006: Jennifer writes: "I tried the alum as suggested for my canker sore. It was really sore and I couldn't take it so I decided to give this a try. I got it at the grocery store for about a dollar. I got the granulated stuff and just put a little pinch on the sore. I felt immediate relief after I rinsed. The pain has definitely lessened a lot overall and I am able to eat with little pain. It has only been about 12 hours since I did it. Another try and it might be completely better! Thanks!! PS it tastes bad and stings a little but definitely worth it."



06/09/2008: Debbie from Toronto, Canada replies: "I have not tried alum as yet but was told that it"s good for tightening the skin. I just don't know were to get it to buy in Toronto so this is my question, were do I get alum to buy? so that I can comment back on how it works. please write back to let me know."

EC: Alum is sold in the spice section of grocery stores.

I have one on my tongue too but that one seems to still bother me... I am going to put the alum on it again today.. so with my fingers crossed I hope it will help that one too. I did have my drug store order me some Rembrant toothpaste without that SLS in it. The net rated that one the #1 choice. I'll try anything!"

[YEA]  04/21/2006: Dan from Dayton, Ohio writes: "I have used alum for canker sores for nearly 3 decades. The alum is usually found in the spice section of grocery stores. I have found from experience that the granulated version is much better than the powder, which often dissolves too quickly in your mouth to do the job properly. I have found the best method is to wet the end of a finger, then dip the finger into the alum granules. This should get quite a lot of them to stick to your finger. Then make sure that the canker sore is thoroughly wetted, and press the finger with the alum crystals against the sore. Hold it there for approximately 3 to 5 minutes. It also helps if you lay down while doing this, and orient the cold sore so that it is up, and not down. This helps keep the inevitable saliva from washing away the alum too quickly. I have found that if I don't lay down and do this, I often have to do the treatment twice. However, by doing this, often a single treatment causes the sore to go into remission within 12 hours. I have often treated the sore when going to bed, and woke up to find it no longer hurting, and on the mend the next morning. This seems to be the most reliable and cheapest way to get rid of canker sores."

[YEA]  04/14/2006: Eddy from Springfield, VA writes: "I have used alum ever since I was a child. I had a lot of canker sores during childhood. It tastes terribly and does burn a little but the canker sore is usually gone with a couple of days. I have not been able to find it lately but I will check the spice section in the grocery store as suggested. I have tried everything over the years, and this works the best! The only thing is to make sure you put the top on tight as it will dry out!"

ALUM, H202, ASPIRIN

1 SIDE EFFECT

[SIDE EFFECTS]  05/17/2008: BC Boy from Smithers, Canada writes: "Remedy Side Effects for Canker Sores: I found Earth Clinic while googling for a canker sore remedy. I was relieved to find so many positive responses to these remedies. So I went and picked up several of the remedies hoping at least one would work as good as stated. I started with Alum. I dabbed a wet finger into the powder and applied it to the 4cm canker sore inside my bottom left gum. At first it stung like salt on an open wound. Then it subsided to the feeling of a butcher knife cutting into my gum. After a half an hour of this I rinsed my mouth out with water and spend 15min in front of the bathroom mirror applying H202 with a q-tip. The pain of applying the H202 eventually subsided to a pounding throb. My mouth was watering so bad I had to stuff kleenex inside my gums to dam the flood. The H202 eventually stopped sizzling so I rinsed and tolerated the dull throbbing ache for 1/2 hr. Finally I applied crushed aspirin to the sore. the aspirin burned but not as much as the alum. My mouth was now feeling like I'd been punched in the face.... twice. My bottom lip was puffy and my gums were numb everywhere except for the sore. I tolerated that for another 15min and finally rinsed the aspirin out with a cold budweiser. It's now been 2hrs later and I'm on my 7th beer and the pain has almost completedly subsided in the past 10min. So far the side affects of the treatment has been tolerable. Hopefully my head won't hurt as bad as my mouth in the morning...."



11/22/2008: Lorik from Blacksburg, Va, USA replies: "WOW talk about an overachiever.. I'm not sure why one would do all three remedies at once.. good grief Charlie Brown!!!"


11/28/2008: Juanita from N.O. , La. USA replies: "OMG... I really believe you over did this, my friend!

I always use Alum at the first sign of a fever blister. All I need to do is wet my finger then touch it to the Alum and apply this mix to the sore for about 15 seconds. It stops the sore in its tracks. You can also use this if you bite your tongue or get a 'lie' bump (swollen taste bud)... It works for me everytime! My neice who is prone to fever blisters found she can keep her outbreaks at a minimum by taking an L-Lysine supplement daily! Juanita"


07/01/2009: CC from Las Cruces, NM replies: "You are too funny! I know what you mean when you just can't take it anymore and you are willing to try anything! You really ARE willing to try anything! Cheers to you!"

[YEA]  04/26/2009: Elle from Austin, Texas writes: "I've used ACV a few times now. It usually helps. I had one bad boy that it didn't seem to have any effect on. I get canker sores A LOT and have determined that orange things tend to give me canker sores. Not real orange things, but things with dye - like original Advil. Actually, I thought I was allergic to ibuprofen for years, but now know it's the coloring. Anyway, ACV does sting it may burn for some people and it doesn't taste that great. I've started using one of the OTC liquid oral pain relievers, then when it's nice and numb I apply the ACV soaked Q-Tip it doesn't seem to have negatively affected its efficacy, and if anything it has helped because I'm a super wimp and it allows me to keep the ACV on longer."

[YEA]  12/24/2008: Michelle from Vancouver, BC writes: "i tried apple cider vinegar. I trusted trying it since if it didn't work as an acid to kill whatever is causing this that baking soda would be alkaline enough to reverse the effects if rinsed immediately after. Apple cider worked to relieve the pain. Have yet to see if sore gets worse or better. I have used apple cider vinegar before. Read a book on it by Braggs apple cider vinegar it was the best type. You can drink it as a cure all for intestinal issues in general. I have acidic issues from over ingesting acidic diet and thought this would not work on me. ome people must have a bacteria behind their canker sores. Ive had them all my life they are horrible and got bigger over the years. I just diluted mine with water two table spoons. Let that act first so it wouldn't shock me. then I put the raw on after initial ouch was getting numb. Rinsed it like an old oral rinse the listerine of nature !Too much of this can it wear down the tooth enamel? Not if you then brush your teeth."
