The nymph who became mint
Mint is named after a nymph: in Greek myth, the water nymph Menthe, lover of Hades, god of the underworld, is turned into the mint plant. The name of the peony (Paeonia) also comes from Paeon, a physician who was turned into a plant. In Egypt, peony root was moved in the shape of a cross over people having epileptic fits, and it was called “haçotu” (cross herb).
