Post by Steve BoninePost by Doug FreyburgerMaybe 20 years ago I made a couple of scratch recipes of root beer
complete with trips to multiple herbalist stores to find all of the
ingredients. Complete with telling the one herbalist "Yes, this
sassafrass is for a bouquet garnee. I know it is not safe for human
consumption." Complete with spending most of a weekend day in the
botany section of a university library reading to see if I was willing
to consume a sassafrass product that I had made myself.
We used to make sassafras tea from the roots of the tree as a spring
tonic. I'm had not realized that our FDA protectors have decided that
it is dangerous.
Saferol, the active flavor ingredient in sassafrass, was discovered to
be a carcinogen. You may remember that root beer tasted a lot better
when we were kids and then it started tasting fake. That's when they
switched to artificial flavoring that attempts to emulate the saferol
without being cancinogenic.
My day in the botany section was to figure out the relative doses used
on the rats to trigger the cancer. I calculated that I would need to
drink gallons of root beer per day for decades to hit that dosage of
saferol. At that point I concluded that much real root beer would kill
me from diabetes from the sugar long before it would give me cancer.
Clearly no one should accept my conclusion on this. If you're going to
decide to brew something with a carcinogenic ingredient don't take
anybody's word for anything.
Doing it today I would use the wintergreen chemical instead. It is
found in both wintergreen leaves and birch bark. If you've ever had
Birch Beer it's basically a root beer tonic with either birch bark or
wintergreen in the place of sassafrass. Brewing with ingredients that
are not carcinogenic is a pretty good idea!
