Herbal Commentary-Stevia

Stevia’s use originated in the Amambay mountain region with the Guarani Indians; who originally called it “kaa he-he” or “sweet herb”.  As a substitute for sugar, stevia appears to have ample potential, with no calories and no increase in blood sugar after consumption.  One study done by a Perdue University biochemistry professor in 1968 appeared to draw a connection between the use of stevia and a contraceptive effect in rats.  In response, the FDA has taken action to allow the marketing of stevia as a dietary supplement rather than an ordinary food product.  The 1968 study has various factors which need to be considered before drawing conclusions.  Chiefly among these is a very high concentration of stevia administered in a brief amount of time (10 milliliters given in 20 minutes).  Also, this one finding with rats may not necessarily reproduce the same effects in humans.  Kuc admits the study “absolutely needs to be redone”.  Dozens of studies analyzing stevia’s effects on rats and humans appear to indicate that there are no adverse effects with stevia’s use.  Much of this research is at least twenty years old and could likely benefit from updated trials.  This could potentially clarify some of the contradictory claims regarding stevia's biological implications.  The implications of lobbying (in this case with the artificial sweetener industry should be considered when looking at how stevia is being regulated).  From this industry’s perspective, stevia has the potential to create a competitive industry that’s likely to drain profits.  As such, scientific scrutiny should precede monetary and/or political ambitions.
