Re: Dried Licorice Root Fights the Bacteria That Cause Tooth Decay and Gum Disease, Study Finds

There are reports going around that say Stevia can cause and/or make cancer worse. What say you to those?

I have never seen any evidence to this claim.  In fact, the steroidal saponins in stevia actually have strong anti-cancer effects.  Stevia also contains caryophyllene that is very effective against H. pylori linked to stomach cancer.  

In another study printed in the journal Biological and Pharmaceutical Bulletin researchers found that the steviol molecule blocked the effects of the potent carcinogen TPA.

Therefore, stevia has many potential anti-cancer compounds.

The concern over stevia causing cancer was from a study where researchers found that the compound stevioside could be converted in to a mutagen by a bacteria found in the stomachs of rats.  Not good news for rats, but really not a concern for humans since this has not been demonstrated in humans.
