Pour warm water over your sassafras roots so they're thoroughly wet. Scrub each root with a small scrub brush, loosening dirt and grime. Rinse them in warm water five or six times to ensure they're clean.
Chop your roots up into fine pieces, making sure to reserve any bark that falls off of the roots. The bark is where most of the flavor is. Scoop about a tablespoon of chopped bark into a square of cheesecloth and tie it into a bundle.
Bring 3 cups of water to a boil in a tea kettle. Remove the kettle from heat and toss in the cheesecloth-wrapped sassafras root. Let the tea steep for about 10 minutes. Remove the cheesecloth. Fill a mug with tea and sweeten to taste with honey or your preferred sweetener.
