The primary germ-killing part of oregano oil is a substance called carvacrol. Oregano is a traditional herb that has been used for thousands of years for natural immune support. New science continues to prove its broad power to be of help.

A just published study tested oregano oil and other essential oils against 10 human pathogenic bacteria including E.coli, Salmonella, and Staphylococcus.  Of all oils tested oregano had the highest and broadest germ-killing activity and carvacrol1 was shown to be the strongest anti-bacterial component in all oils tested.  Another study of oregano oil on Staphylococcus2 used an electron microscope to evaluate the bacterial cell after exposure to oregano oil.  The cell was significantly disturbed, indicating oregano oil’s ability to directly damage bacteria while at the same time reducing the ability of the bacteria to generate toxins that damage human health.

One of the great problems of antibiotics is that they do not kill yeast/fungus like Candida albicans.  This tends to cause Candida overgrowth when antibiotics are used.  Oregano oil is different in that it also kills yeast and fungus.  A recent study showed that oregano oil3 inhibited all forms of Candida tested.  Another study using an electron microscope showed that oregano had powerful anti-fungal properties4, disrupting the formation of Candida gangs called biofilms.

At this time there are no reports of bacteria or Candida becoming resistant to oregano oil.
