get some sassafras (probably can find it out in the woods near you, too).
Sassafras has been shown to be carcinogenic -- you can look it up online. Wish I'd known that before I drank all that sassafras tea when I was a kid!
yes, and so are basil, pepper, cinnamon, nutmeg, and several other commonly used herbs which all contain safrole, which is the carcinogenic. you can buy safrole free extract. although banned by the fda, there hasn't been any substantial studies on the actual affects on humans, oddly enough, and the base test of was based on overloading rats with safrole oil and seems that rats turn safrole into a carcinogen whereas humans do not, but oh well. from the conspiracy theorist in me the beer companies, the major cola companies, and the us military (who was rumored to be playing around with ecstacy in the 1950s) forced the ban. beer is like much more carcinogenic than sassafras tea, none of the other herbs which contain safrole are banned, there is nothing like root beer. i guess i'll still boil some sassafras roots in the woods just to boost morale.
