Be aware sassafras a very good blood thinner. Years ago when i got hurt by a bull i ended up taking warfarin. I replaced my dosage with a quart of sassafras tea each day, it was just as effective (my gp doctor loves me ).
I always liked the smell, it's easy to find a sassafras tree, even in the dark. And, the filé powder in gumbo is dried sassafras leaves. Traditionally the leaves are harvested during the full moon of august for drying. The roots are used for tea...
