How can we naturally eliminate the annoying smell emanating from our mouth after eating garlic or onion based foods? Here are the best natural remedies to avoid the problem ofhalitosis from garlic and onion.

We all know how embarrassing it can be to talk to someone right after having a meal where the presence of garlic or onion was abundant. These foods are similar in their composition, in fact they contain sulfur compounds responsible not only for the smell, but also for their pungent taste which affects our breath.

When garlic and onions (especially raw) are digested, they release odorous molecules that reach the lungs through the bloodstream and give rise to bad breath.

The bad breath that comes from the consumption of these tubers can go on for many hours, so it is good to know some tricks to get rid of the problem quickly. We present 10:



According to a study published in the Journal of Food Sciences, milk can significantly reduce the concentrations of the odorous compounds produced by garlic and onion. The result will be better if you drink a glass of whole milk which, according to research, tends to deodorize some of the compounds present in these bulbs more effectively than skim milk.


The citric acid contained in lemon can neutralize the smell of onion and garlic in the mouth. It also has antibacterial properties that help eliminate the microorganisms that contribute to bad breath. You can therefore try to take a tablespoon of lemon juice and add it to a cup of water, mixing well before rinsing your mouth with this solution at least 2-3 times until the unpleasant odor is eliminated.

Sodium bicarbonate

Baking soda is another home remedy that can be used to neutralize bad breath by acting on the pH of the mouth and inhibiting the growth of bacteria. Add a teaspoon of baking soda to lukewarm water with a pinch of salt and use this solution to rinse until no more bad odor is noticed.


Among the aromatic herbs, especially the fresh scent of parsley and mint can help mask the unpleasant smell of onion and garlic. Plus, they have a purifying effect that helps your mouth stay clean. Just chew a few leaves of these herbs for a few minutes.


The natural enzymes contained in apples help to break down sulfur compounds and therefore the problem of bad breath from garlic and onion. You can drink a glass of apple juice or eat one of these fruits as needed.


One study indicated that the chemical composition, not only of raw apples but also of lettuce, help deodorize the breath compromised by garlic and onion. You can then, at the end of a garlic and onion-based meal, end with a nice lettuce-based salad that will freshen your breath.

Essential oils

Essential oils can be used to rinse in order to improve your breath, refreshing it and with an antibacterial effect. You can add 2-3 drops to a tablespoon of coconut oil and hold the mixture in your mouth for a few minutes before spitting. The most suitable essential oils to counter the problem are mint, rosemary and eucalyptus.

Green tea

Drinking a cup of green tea after a garlic and onion meal can temporarily reduce odor by providing time to get to the bathroom to brush your teeth. Also great to add a little fresh lemon juice.

Brush your teeth and tongue

Before using any natural remedy, if you have the possibility, it is good to brush your teeth, brushing for a few minutes and also using dental floss. Don't forget to clean your tongue with the tongue cleaner or, alternatively, with a spoon. This helps eliminate the bacteria that worsen the bad breath problem.


It seems that sugar is also an effective remedy, the grains that make it up (choose a version with larger grains, for example brown sugar) help to remove the bacteria that promote bad breath. So keep a small portion of sugar in your mouth for some time before chewing. In this case, the teeth will need to be brushed immediately afterwards.
