Staphylococcal Infection

Oregano Oil and Staphylococcal Infection

What is a Staphylococcal Infection?
Staphylococcus Aureus are spherical gram-positive bacteria that appears in grape-like bunches. Though there are more than 30 kinds of Staphylocci, Staphylococcus Aureus is the most common type that causes human infections.

Staph infections can cause a multitude of diseases. When it affects the skin, it can lead to impetigo, cellulitis and in severe cases, the scalded skin syndrome. When it is transmitted to nursing mothers, they can experience breast inflammation or mastitis.  The Staphylococcus Aureus can also enter the bloodstream and cause sepsis, which can lead to acute organ dysfunction. When it enters the lungs, it can cause pneumonia and if it spreads to the heart, it can cause endocarditis which may eventually lead to heart failure. The bacteria can also cause food poisoning when a person eats food contaminated by Staphylococcus Aureus toxins.

How can oregano oil relieve a Staphylococcus Aureus infection?
Carvacrol, an isomeric phenol, is a major component of oregano oil and is known for its antibacterial characteristics. It is effective in fighting many bacteria including Staphylococcus Aureus (Lopez, et al., 2007).

In a study conducted by Dr. Harry G. Preuss and his team in 2001, oregano oil was shown to be as effective as antibiotics such as Streptomycin, Vancomycin and Penicillin. Scientists compared the minimum inhibitory concentration values of both methicillin-susceptible and methicillin-resistant staphylococci against Origanum vulgare and they observed no significant differences (Nostro, et al., 2007).

How is oregano oil used in diseases caused by the Staphylococcus Aureus?
Oregano oil can be used internally or externally, depending on the degree of infection present. Taken internally, one to two drops can be added to a full glass of honey (and water), juice or olive oil and ingested every day. You can also increase the dosage to four times a day when you get used to it. Pregnant and lactating mothers should not use anything without the knowledge of their doctor. Extreme caution should also be taken by very young and very old people. Sick people and those who are taking medications and supplements are also advised to consult their doctors to avoid any adverse reactions.

Externally, diluted oregano oil can be placed topically, especially for skin infections. Remember to be careful in applying it to body orifices, especially in the genital area. It can be diluted in coconut or olive oil to decrease its potency. To be safe, do an allergy test to a small patch of skin under the arm to make sure you’re not allergic to it.

A Staph infection should always be taken seriously as it can quickly spread to other people, especially the immunocompromised and can cause serious and sometimes life-threatening diseases. Take advantage of this natural and inexpensive antibacterial and use oregano oil to help relieve your Staph infection.
