Staphylococcus bacteria and was comparable in its germ-killing properties to
antibiotic drugs such as streptomycin, pencillin and vancomycin. [Science
British researchers reported oregano

has shown that oil of oregano can be used to treat intestinal parasites.

One study, published in the Journal of Applied Microbiology in 1999, compared 52
plant oils and extracts. Oregano essential oil was found to have significant
antibacterial action against a wide number of bacteria including E coli, Staph,
Salmonella enterica, and Klebsiella pneumonie, which is a pneumonia that
frequently occurs in people with a weakened immune system. The following year,
the Journal of Applied Microbiology published a study by Scottish researchers
that showed oregano essential oil to be effective against 25 different bacteria. Other studies, such as the one done by researchers at the University of
Tennessee in 2001, also showed oregano oil to have powerful antibacterial
Research published in the International Journal of Food
Microbiology in 1988 found oil of oregano to be an excellent antifungal,
completely inhibiting the growth of the nine fungi tested. Since that time,
numerous research studies have been published that repeatedly show the ability
of oregano essential oil to kill yeast, including Candida albicans.
Oil of oregano is not to be confused
with common oregano in the kitchen spice cupboard, which is usually marjoram
(Origanum majorana or O. vulgare) rather than true oregano (Origanum vulgare).
Antibiotic resistance has become a
real problem as various germs have become more and more resistant to various
antibiotics. Drug resistance does not develop against naturally-occurring
antibiotics such as garlic and oil of oregano.
