Mint is a good appetizer and promotes digestion, due to its typical aroma. It also soothes stomach in cases of indigestion, inflammation etc. This aroma of mint activates the saliva glands in our mouth as well as glands which secrete digestive enzymes, thereby facilitating digestion. Thus it is extensively used in culinary.
The strong aroma of mint is very effective in opening up congestion of nose, throat, bronchi and lungs, giving relief in respiratory disorders resulting from asthma, cold etc. As it cools and soothes throat, nose and other respiratory channels, it gives relief in cough too. Many balms are based on this property of mint. Unlike other inhalers which are based on aerosols, those based on mint are more effective and eco-friendly too.
Regular use of mint is very beneficial for asthma patients, as it is a good relaxant and gives relief in congestion. But, over dosage may irritate as well.
