Oregano Oil: More Powerful Than Antibiotics? (Unlike antibiotics, oregano oil kills viruses and parasites too)

I love to travel and was fortunate enough to travel to Colombia, Thailand, Peru, and Nepal last year. While these countries are beautiful, exotic and fascinating to visit, their sanitation, and water supplies—as well as food preparation—are not up to the same standards as we have in the United States. In spite of taking all the usual precautions, both my significant other and I got very ill in Colombia. In fact, we were sick for a good two and a half weeks after we got home, with all the symptoms of a serious Giardia infection, which is an amoebic parasitic infection. Symptoms include: fever, aches, pains, chills, severe stomach pains, diarrhea, nausea, weight loss. It was miserable!

The general conventional treatment for giardia infections is a prescription antibiotic, which as  you probably already know, will wipe out all the beneficial bacteria in your body, as well as the bad stuff. In addition, many infections are now antibiotic-resistant, making them even harder to eliminate with conventional medical antibiotics. Before resorting to antibiotics, I thought I’d try a proven natural remedy first.

After doing some research, I purchased oregano oil capsules, took as directed, and was good as new in 24 hours. Now we never travel without it—and it has saved us numerous times! As soon as I feel any kind of tummy troubles coming on, I start taking the recommended amount as a precaution, and viola! All good! In fact, I can say, that since that trip to Colombia, I have traveled to Thailand, Peru and Nepal and have not had any ‘issues’ whatsoever!

Oregano oil to the rescue!

Oregano has been used all the way back in ancient Grecian times as a highly effective medicinal herb. The Greeks used it for wounds, insect bites, snakebites, digestive and respiratory infections–and for good reason–oregano oil is the ultimate natural antibiotic, antiviral, and antifungal!

Oregano essential oil has been proven scientifically to kill bacteria, viruses, fungal infections, and parasites, including giardia, an amoebic infection. Oregano oil has actually been scientifically proven to be effective against even antibiotic-resistant pathogens.

Oregano oil is also incredibly effective against food poisoning, stomach flu, candida infections, ringworm, eczema, sinus infections, nail fungus, acne, skin infections, insect bites, warts, allergies, and more. However, oregano oil is very strong and can be irritating, so it must be diluted in a carrier oil when using on the skin. When taken internally, it is best to purchase and take as a prepared capsule, so you get the proper strength and dosage.

The active ingredients in oregano oil include phenols, carvacrol (60-80%) and thymol (5%) which provide its antiseptic, antifungal, antiviral and antioxidant components. Other ingredients include terpenes, pinene and terinene which contribute to the antiseptic, antiviral, anti-inflammatory and anesthetic properties.

All in all, over 800 studies have been conducted on oregano oil and its amazing healing abilities.

Carvacrol is scientifically proven to be highly effective in killing off dangerous staphylococcus, norovirus, E.coli, listeria, campylobacter, and salmonella—all organisms that can cause violent food poisoning. Even better than an antibiotic (which only kills of bacteria), carvacrol is a highly effective antiviral as well. Carvacrol is also an anti-inflammatory aid, and can be used to calm down redness and swelling due to injuries or allergic reactions and insect bites. Studies show carvacrol works against candida overgrowth in the mouth or digestive tract, helps kill cancer cells, and even helps to lower blood sugar.

Oregano essential oil is one of the most potent, versatile natural medicines. Keep it on hand at all times, and you are sure to enjoy its powerful and effective healing properties.  Also, don’t miss this article:

      • Eden’s garden has had several independent studies on their oils. I personally use them for everything and the work great. I tried young living. They work but cost almost twice as much as Eden’s garden. Eden’s garden does not sell through pyramid sales so can keep their prices reasonable.
