The Latin word for sage is 'salvia'. 'Salvia' stems from the word 'to heal'.
Burning sage is a very old method of cleansing a space, or a person.
The best sage to use for such purposes is white sage. It's an easy process. Put the save in a heatproof earthenware pot. Light it for a few seconds before putting out the flame and letting the smoke rise up.
