Mint is well known for its ability to sooth the digestive tract and reduce the severity and length of stomach aches. In addition, mint teas and other herbal preparations have shown great promise at easing the discomfort associated with irritable bowel syndrome, and even at slowing the growth of many of the most harmful bacteria and fungi. The well-documented antifungal properties of mint are thought to play a role in the treatment of asthma and many allergy conditions as well.
It is even thought that mint may have benefits as an anticancer food. Mint is known to contain a phytonutrient called perillyl alcohol, which has been shown in studies on animals to prevent the formation of colon, skin and lung cancer. Further study is needed to see if this important benefit extends to the human world.
