One of the top anti-viral, anti-fungal, anti-bacterial oils, in tests against Penicillin and Ampicillin Oregano and Cinnamon were shown to be comparable in inhibitory activities again E. coli and Staphyloccus aureus.
In addition, Oregano has been shown to have tremendous anti-fungal properties as it and Thyme oil are the most potent anti-fungal oils that I have found. Oregano is powerful anti-fungal, anti-bacterial for the respiratory, intestines, genitals, and it has great benefit for nerves, blood and lymphatics.
