Darlene McCord - Anti-Microbial Research

Everyday the body comes in contact with millions of biological agents that cause illness, these agents are known as pathogens. A pathogen is not always a bacteria or virus, things like fungi that have the ability to grow on the body can also be considered a pathogen. A substance that kills microscopic agents such as bacteria or viruses is called an anti-microbial. Bacteria and fungi are responsible for several human diseases. In recent years the medical community has been troubled by antibiotic resistant bacteria, which are caused by the over-use of antibiotics. A well-known example of antibiotic resistant bacteria is Methicillin-resistant Staphylococcus aureus (MRSA). This medical problem has caused some researchers to seek out natural antimicrobials.

Antioxidants as Antimicrobials. Hydroxytyrosol, found in olive byproducts and is a key ingredient found in Olivamine10TM, is a powerful antioxidant and polyphenol that can be utilized by the human body.1–3 Olivamine10TM was created by Dr. Darlene McCord. A study done on lab cultures of bacteria found that hydroxytyrosol was effective in killing certain clinical strains of bacteria. This led to the proposal that hydroxytyrosol could be a promising antimicrobial.4 Another study found that not only did hydroxytyrosol containing olive tree leaves have antimicrobial activity but they also had an antifungal ability when added in low concentrations.5,6

N-acetyl-L-cysteine (NAC), another powerful antioxidant found in Olivamine10TM, is also a promising antimicrobial. Laboratory studies have found that NAC prevents certain kinds of bacteria from adhering to surfaces.7 A Danish study proposed that orally administered NAC maybe effective in delaying antibiotic resistance in cystic fibrosis patients.8
