Mouth ulcer, also known as aphthous ulcer or stomatitis is a swelling of the mucous membrane in the mouth and lips which ultimately leads to ulcerative lesions. Mouth ulcers may develop due to various causes. It could be just because of an accidental cheek bite or due to vitamin deficiency. Allergy to certain foods like gluten or citrus foods like strawberry or nuts may also lead to mouth ulcers. Mental stress and herpes virus infection are some other causes of oral ulcers. Primary symptoms of mouth ulcers include redness in mucous membranes, difficulty in swallowing and eating, which leads to dehydration. Saliva drooling and swelling of gums can also occur in case of mouth ulcers. The only complication of the mouth ulcer is its’ recurrent tendency.

Proper dental care along with avoidance of hot foods and drinks aid in the prevention and treatment of mouth ulcers. Homeopathy provides a safe and effective treatment for mouth (aphthous) ulcers. Some of the common homeopathic remedies that are frequently used to treat mouth ulcers are Borax, Acid Nitricum, Carbolic aid, Mercurius corrosivus, and Mercurious solubulis.

As per homeopathy, oral ulcers are not only caused due to deficiency of vitamins but also when your body is not able to assimilate vitamins from the diet. Homeopathic medicines will help the body to absorb these essential vitamins thus improving mouth ulcer symptoms. 

In a research done with 100 individuals suffering from minor aphthous ulcers, all the subjects were given homeopathic medicines in the lowest potency twice daily after every 12-hours. Pain, size and number of aphthous ulcers were found to be reduced within 4 to 6 days in all of the subjects. No side effect was reported in any individual.

A Homeopathic physician not only considers disease symptoms but also individual symptoms before selecting and prescribing a certain remedy. To understand this let us see a case study. A person suffering from mouth ulcers also complained of headaches, and nightmares, along wih excessive worries and anxiety. Based on all this, he was prescribed sulphuric acid which cured all the symptoms. This is because homeopathic treatment not only treats disease symptoms but also the underlying miasm or tendency to suffer from a disease. In this case sulphuric acid treats the underlying cause of the disease and works well in anxious and over worried individuals.

Only by treating the miasam, will effective treatment be achieved and recurrence is voided. So, pain, and burning, which present early, are psoric manifestations of mouth ulcers, whereas, offensive, foul-smelling discharge from the ulcer is a presentation of a more advanced and destructive syphilitic miasm.

Interestingly, the homeopathic concept of simmilars is now being used to prepare an entirely new generation of homeopathic drugs by potensising conventional medicines. According to this study, homeopathically prepared doses of conventional medcines can be used for the treatment of symptoms which appear as a side effect of the said drug for example: medicines like abacavir (which is used for treating HIV but causes severe hypesentivity) and anti-inflammatory drugs (which can cause stomach pain, rashes and allergy) can be potentised and used homeopathically for treating ulcers and other such gastric conditions. 

It has been known that homeopathic medicines are safe to use when taken under the guidance of an experienced doctor.  It helps in alleviating the root cause of the disease and preventing relapse. There have been no documented side effects with the regular use of homeopathic remedies.
