Oregano (Origanum vulgare) is a popular flavoring ingredient used in Mexican, Italian and Spanish cuisine. Rosmarinic acid, the active substance present in oregano, is a powerful antioxidant—almost 42 times more than the antioxidants present in apples—that improves immunity.(1)

It also contains beta-caryophyllene, a substance that is known to stop inflammation and could be beneficial for arteriosclerosis (hardening and thickening of the walls of the arteries), osteoporosis and hypertension.(2,3)

Oregano For Infections
Oregano has essential oils that could kill the foodborne pathogen ‘listeria’ and the superbug MRSA (that causes Staph infections). Essential oils obtained from oregano have antifungal properties and are effective against certain Candida species.(4,5,6)

The antiviral, antibacterial and antifungal properties of oregano oil can be useful in:

  • Preventing the growth of bacteria causing respiratory infections (Klebsiella pneumoniae and Staphylococcus aureus) and curtailing the growth of multi-drug resistant bacteria.(7,8)
  • Stopping the growth of E.coli, Pseudomonas aeruginosa and Proteus, bacteria that cause urinary tract infections.(9)
  • Dealing with parasitic infections. It is more effective against the parasite Giardia than the drug tinidazol.(10)

How To Use It
1. To treat sinus infections or cold, put four to five drops of oregano oil in a pot of steaming water or a vaporizer. Inhale the steam twice a day.

2. For parasitic infections, take a drop each of oregano and coconut oil (carrier oil) in a spoon and mix it. Keep it under your tongue for two to three minutes and rinse your mouth with water. Repeat this four times a day to see an improvement.

3. To treat fungal nail infections and athlete’s foot, soak your feet in a tub of warm water, with two to three drops of oregano oil added to it, for 10 minutes every day for a week for relief. You can buy oregano oil here.
