There are many health benefits for eating mint. Some of these benefits are:

Respiratory Disorders and Coughs: The strong aroma of mint is very effective in clearing up congestion of the nose, throat, bronchi and lungs, which gives relief for respiratory disorders that often result from asthma and the common cold. As mint cools and soothes the throat, nose and other respiratory channels, it relieves the irritation which causes chronic coughing. This is the main reason why so many balms are based on mint. Unlike the inhalers that are based on aerosols, those with mint as the fundamental component tend to be more effective and eco-friendly as well.

Asthma: Regular use of mint is very beneficial for asthma patients, as it is a good relaxant and relieves congestion. That being said, using too much mint in this way can also irritate the nose and throat.

Breast Feeding: For many women, breastfeeding is a beautiful part of raising a child, but it can seriously damage your breasts and nipples. Studies have shown that mint oil can reduce the nipple cracks and nipple pain that so often accompany breastfeeding.

Depression and Fatigue: Mint is a natural stimulant, and the smell alone can be enough to charge your batteries and get your brain functioning on a high level again. If you are feeling sluggish, anxious, depressed, or simply exhausted, mint and its derivative essential oils can help. It can be ingested, applied topically in a salve form, or inhaled as a vapor, and all of those techniques can give you a much-needed boost! A popular way to get good results in an easy manner is to put a few drops of mint essential oil or menthol oil on your pillow at night and let it work on your body and mind while you sleep.
