🌱 What it is
Sassafras is a tree whose root bark was traditionally dried and brewed as a tea, prized for its distinctive spicy-sweet aroma, historically used as a spring tonic and blood purifier.
📜 Where it comes from
Sassafras root was used by Native American tribes and early American colonists as a spring tonic tea, and it became one of colonial America's earliest export crops. Its reputation as a blood cleanser and flavoring endured for centuries until safrole, its key aromatic compound, was found to be a liver toxin and carcinogen.
