Why should a man die who has sage in his garden?ancient Roman proverb
The name comes from the Latin salveo, to heal, and for the Romans, sage was a sacred herb; drinking sage tea was supposed to help a woman conceive, and it was believed to have healing powers. One had to bathe and have clean feet, put on clean clothes, and make a special food sacrifice, before even cutting it (with a non-iron knife). They also used it as a kind of toothpaste.
It's still used throughout the Big Boot—popular with melted butter on pasta or gnocchi, or with meat dishes, in sauces, sausages, and more.
