In a recent test, NRCS's botanical extract was used to clean a surface infection of E. coli. In the test, E. coli was introduced to a surface and allowed to dry. Then, the surface was cleaned with four different solutions; phosphate buffer saline (PBS), NRCS's product, 70% ethanol, and a common commercial disinfectant. The surface was then swabbed and the sample was transferred onto a petri dish containing a growth medium. The E. coli was allowed to grow for 24 hours before the observations were made (Figure 1).

The results show that PBS and the common commercial disinfectant were unable to eradicate E. coli from the surface. The NRCS product, as well as ethanol, were both able to eradicate E. coli from the surface effectively.
