I had read that they stopped using sassafras as a flavoring for root beer when it was shown to cause cancer in rats.
From the website: https://www.verywellfit.com/sassafras-tea-benefits-and-side-effects-4163470
"The volatile oil—or rapidly evaporating essential oil— found in the roots of the sassafras tree contains safrole. Safrole has been classified as a Substance Generally Prohibited From Direct Addition or Use as Human Food. Concerns about safrole became significant after studies conducted in the 1960s and 1970s showed that safrole caused cancer in rodents."
I do not know if those studies are true of not, or if their scientific processes even make sense. I know some of the "scientific" studies we looked at in college that "prove"d something causes cancer was administered to the test rats at such a high concentration that there was no way that they couldn't get sick and die.
