Peppermint is one of the oldest known herbs. In fact, it has been found in 3000 year old Egyptian tombs. The Japanese cultivated it 2000 years ago as a source of menthol and it is still used today as the primary ingredient in many commercial medicinal remedies. Peppermint has been known to relieve gastrointestinal disorders, local aches and pains, and to reduce stress. Its aroma is refreshing and rejuvenating, and its taste is deliciously clean and wintry. Many studies have reported that peppermint can be used to boost mental powers; so much so, that it is even given to children prior to testing in many schools! Peppermint is a hybrid cross between water mint and spearmint and is rich in vitamin B, calcium and potassium.
