5. Marmite
Marmite has long been suggested for use on ulcers. Ulcers are large and painful blisters that can form on the tongue as a result of stress or even trauma to the tongue. These then have a nasty tendency of catching on your own teeth, rubbing on things, or hurting when you drink sweet drinks or hot ones.
The advice has therefore been to try and address this problem by eating marmite and there is a lot of anecdotal evidence to suggest that this can be effective. The reason for this is not fully understood however there are two possible explanations for why it may be effective.
One is that marmite is high in vitamin B12 – and many people who have ulcers have been found to have low B12. This could simply be replacing a deficiency in that case.
At the same time, marmite is a yeast extract that may help to combat fungal infections and fix imbalances to flora.
