How much Sassafras is usually taken?
The safety of long-term internal use of sassafras has not been proven. Only guaranteed safrole-free products should be consumed. Note that safrole-containing food products are illegal in the United States and Canada.8 Some sources suggest a dilute tincture can be used in the amount of 1 to 2 ml three times per day.9 Volatile oil of sassafras can be applied topically three times per day for lice, but should never be taken internally.
