The Truth About Antibiotics

Updated: Jan 15

Antibiotics are widely used to treat infections and diseases caused by bacteria. While killing harmful bacteria, antibiotics also kill good bacterial strains that we need. Even a single antibiotic dose can lead to detrimental shifts in the composition and diversity of the gut flora (1).

As per the CDC, doctors prescribe about 47 million antibiotic courses each year for infections that don't need antibiotics (2). The unnecessary prescribing of antibiotics has resulted in about 1 in 3 people suffering from yeast-related symptoms or conditions like yeast and candida overgrowth (3).

Dangers of Antibiotics

In 2015, healthcare providers prescribed 269.4 million antibiotic prescriptions—equivalent to 838 prescriptions per 1000 persons. The most commonly prescribed antibiotic was Azithromycin, and 46.2 million doses were prescribed (4). Like all medications, antibiotics have a long list of side effects, so let's discuss the side effects of the most commonly prescribed antibiotic, Azithromycin (5):

  • Abdominal or stomach cramps or pain (severe)

  • Abdominal or stomach tenderness

  • Agitation

  • Black, tarry stools

  • Bleeding gums

  • Blistering, peeling, or loosening of the skin

  • Bloating

  • Blood in the urine or stools

  • Bloody or cloudy urine

  • Blurred vision

  • Chest pain or discomfort

  • Chills

  • Coma

  • Confusion

  • Constipation

  • Convulsions

  • Cough

  • Darkened urine

  • Decreased urine output

  • Difficult or labored breathing

  • Lethargy

  • Light-colored stools

  • Loose stools

  • Loss of appetite

  • Muscle pain

  • Muscle twitching

  • Nausea or vomiting

  • Pain

  • Pains in the stomach, side, or abdomen, possibly radiating to the back

  • Pinpoint red spots on the skin

  • Puffiness or swelling of the eyelids or around the eyes, face, lips, or tongue

  • Rapid weight gain

  • Red skin lesions, often with a purple center

  • Red, irritated eyes

  • Skin rash

  • Sore throat

  • Sores, ulcers, or white spots in the mouth or on the lips

  • Stupor

  • Sweating

  • Swelling of the face, mouth, neck, hands, and feet

  • Swelling of the hands, ankles, feet, or lower legs

  • Tightness in the chest

  • Unusual bleeding or bruising

  • Unusual tiredness or weakness

  • Yellow eyes or skin

Aside from the long list of side effects, anytime antibiotics are used, they can contribute to the pandemic of antibiotic resistance. This is because antibiotics increase antimicrobial resistance and are driven by a combination of germs exposed to antibiotics, the spread of those germs, and their mechanisms of resistance (6).

Although the Centers for Disease Control (CDC) claims antimicrobial doesn't mean our body is antibiotic resistant, the World Health Organization (WHO) admits the misuse (or overprescribing) of antibiotics in humans and animals is accelerating the process (7). Unfortunately, in the U.S., more than 2.8 million antimicrobial-resistant infections occur each year, resulting in more than 35,000 deaths (8).

Additionally, antibiotics can also lead to long-term changes in the gut flora. After completing an antibiotic dose, most bacteria return after 1–4 weeks, but their numbers usually don't return to the prior levels (9). Another study discovered that a single dose of antibiotics diminished the diversity of Bacteroides, one of the most dominant bacterial strains, and boosted the number of resistant strains. These consequences remained for up to two years (10)!

So what can we do when we need an antibiotic but aren't comfortable with taking a prescription?

That's where oil of oregano comes in.

Oil of oregano sometimes referred to as oregano oil (not to be confused with oregano essential oil), is made by infusing extra virgin olive oil with dried oregano leaves, creating a robust and ingestible "natural antibiotic" widely used in the natural community.

Before I go over my oil of oregano recipe in the next section, I figured I would share some premade oil of oregano options for those who may not be ready to start creating their own herbal remedies.

  • Gaia Herbs' Oil of Oregano Capsules are a natural antioxidant source, containing phytochemicals that help support the body's natural resistance to immune challenges. Gaia Herbs' supercritical CO2 extract of oregano volatile oils contains phenols, including carvacrol and thymol. These oils help support the intestines and a healthy immune response.

  • Garden of Life's Oil of Oregano Drops offers traditional support with modern convenience, delivering 34mg of Organic oregano leaf extract in a base of cold-pressed extra virgin olive oil & mixed tocopherols from non-GMO sunflower.

Benefits of D.I.Y. Oil of Oregano

Oregano's medicinal properties stem from compounds like phenols, terpenes, and terpenoids, with powerful antioxidant properties (11):

  • Carvacrol is the most abundant phenol in oregano and has been shown to stop the growth of several bacteria types (12).

  • Thymol is a natural antifungal that supports the immune system and protects against toxins (13).

  • Rosmarinic acid is a powerful antioxidant that helps protect against free radical damage (14).

Additional benefits of oregano include:

  • Rich in antioxidants (15)

  • Antibacterial properties (16)

  • Antimicrobial properties (17)

  • Antiviral properties (18)

  • Anti-inflammatory properties (19)

  • May prevent and kill certain cancers (20)

D.I.Y. Oil of Oregano

Ingredients & Materials:


  1. Gather your ingredients, preferably organic: dried oregano, extra virgin olive oil, a mason jar, and a canning jar lifter.

  2. After you've gathered your ingredients, add the dried oregano and extra virgin olive oil into a mason jar, and close the lid.

  3. After you've closed the lid, prepare to infuse the oil by filling a pot with water and bringing it to a boil.

  4. After the water has come to a boil, place the mason jar in the water, bring it back to a boil, and leave for 10 minutes.

  5. After it has boiled for 10 minutes, remove the jar with a canning jar lifter, shake it, and keep it in a cool, dark cabinet for two weeks. Shake the jar at least once a day.

  6. After it has sat for two weeks, strain the mixture into another airtight container. It will yield roughly 6 ounces (I used an old 8 oz. Earthley tincture bottle).
