EFFECTIVENESS OF STEVIA REBAUDIANA WHOLE LEAF EXTRACTAGAINST THE VARIOUS MORPHOLOGICAL FORMS OF BORRELIA
BURGDORFERI IN VITRO
Stevia is known mostly as a non-toxic alternative sweetener to sugar, but researchers are finding that some brands of stevia confer antimicrobial benefits as well, particularly against Borrelia burgdorferi. In a recent study conducted at the University of New Haven, West Haven, CT, researchers tested four types of stevia to determine their antimicrobial effects against Borrelia burgdorferi.
For this study, four types of whole leaf Stevia extract were tested on B. burgdorferi spirochetes, persisters, and biofilm forms in vitro. The susceptibility of the different forms to the extract was evaluated by various quantitative techniques in addition to different microscopy methods. The effects of stevia were also compared to those of doxycycline, cefoperazone, and other drug combinations.
Researchers concluded that three of the four stevias eliminated significant numbers of B. burgdorferi spirochetes and persisters, with the NutraMedix brand (brand “A” in the study) having the greatest effect. When it was tested against attached biofilms, along with three antibiotics, it was also found to significantly reduce B. burgdorferi.
The results of the study indicate that Stevia leaf extract may not just be a healthy sweetener for beverages and desserts, but also an effective anticmicrobial agent against B. burgdorferi.
Many brands of stevia that can be purchased at your local health food or grocery store are not necessarily healthy and often contain toxic additives. These products may or may not provide the same antimicrobial benefits.
