Knock-Out Technologies Ltd., a wholly-owned subsidiary of eFoodSafety.com, is set to begin clinical testing of Proxorin™ for use as a natural antibiotic/anti-microbial in the treatment of common bacterial pathogens. The drug is based on the company’s CitroxinTM formula. Due to its natural composition, Proxorin may be used in a much larger range of health conditions than that addressed by antibiotics.
