Put the water and cedar leaves in a pot with the lid off.
Bring the water and cedar leaves to a boil and then turn it down to the very lowest setting.
Let the cedar tea gently simmer on the very lowest heat for 15 minutes. The steam will carry the antimicrobial oils from the cedar into the air in your house.
Turn off the heat, let the cedar tea sit on the stove until it is cool, then pour it into your bath, use it to wash your hands with, or pour it into your garden.
