In a world where resistant bacteria and respiratory infections are becoming more common, Dr. Mehmet Oz, the famous cardiothoracic surgeon and promoter of natural health, has brought to the public’s attention a remedy with remarkable potential: wild oregano oil (Origanum vulgare).
What Does It Contain and How Does It Work?
Oregano oil is obtained through steam distillation of the plant’s leaves. It is extremely rich in:
- Carvacrol – an active compound with strong antibacterial, antiviral, and antifungal effects.
- Thymol – supports lung health and has antioxidant effects.
- Terpenes – help eliminate mucus and support respiratory function.
These components work synergistically to:
- Destroy harmful bacteria without affecting the good flora.
- Inhibit viruses, including those that cause colds and flu.
- Combat candidiasis and other fungal infections.
- Reduce inflammation in the sinuses, throat, and digestive system.
What Does Dr. Oz Say?
In several episodes of The Dr. Oz Show, the doctor emphasized:
Oregano oil is one of the most effective natural remedies for viral and bacterial infections. I keep it in my travel kit wherever I go. It can reduce the duration of a cold and naturally boost the immune system.
(Dr. Oz – show about superfoods for the cold season)
Recommended Usage
Internal Use (only if for food consumption!):
12 drops in a tablespoon of olive oil, 12 times a day, for a maximum of 10 days.
