Minthe, who gave her name to this genus of plants, was nymph who was pursued by Pluto, Greek god of the Underworld.

Peppermint was used by the ancient Egyptians and the Romans used it for its aesthetic and culinary properties. Pliny wrote about mint in his Natural History (AD77), “As touching garden mint, as the very smell of it alone recovereth and refresheth the spirits; so the tast stirreth up the appetite to meat, which is the cause, that it is so ordinarie in our sharpe (vinegared) sauces wherein we use to dip our meats.” In fact, he found the smell of mint so exhilarating that he recommended a wreath of mint for students, to sharpen the mind. He also extolled its virtues in drying up “the humours that mollifie the grisly windpipe..” and recommended the use of mint juice before any strenuous use of the voice.
In folk legend and country magic, mint was associated with Venus and Mars and was used to invoke protection during travel and exorcism and to attract money, love and healing. One country superstition was to place a few leaves of mint with the family savings in order to make it grow.
Peppermint was also used to aid sleep, in purification and to strengthen psychic powers - placing mint on an altar would draw good influences upon rituals and a sprig, placed beneath a pillow, would enable you to see the future in your dreams.
