Origin of peppermint oil
It is a native of the Mediterranean, but is now also cultivated in Italy, USA, Japan and Great Britain. It is a perennial herb that grows up to 1 meter (3 feet) high and has slightly hairy serrated leaves with pinkish-mauve flowers arranged in a long conical shape.
It has underground runners by which it easily propagates. This herb has many species, and peppermint piperita is a hybrid of watermint (M. aquatica) and spearmint (M. spicata).
According to Greek mythology the nymph Mentha was hotly pursued by Pluto, whose jealous wife Persephone, trod her ferociously into the ground, whereupon Pluto then turned her into a herb, knowing that people would appreciate her for years to come.
It has been cultivated since ancient times in Japan and China. Evidence of use was found in Egypt in a tomb dating back from 1000 BC.
