Oregano Oil Benefits
Research has found a number of potential health benefits of consuming oregano oil:
Several studies have shown the powerful antibacterial properties of oregano oil, even against antibiotic-resistant strains of bacteria.
In one study that tested the antibacterial effects of a range of essential oils, oregano oil was found to be the best at hindering bacterial growth.
Because it can protect against bacterial infection, topical oregano oil has been shown to be effective in wound treatment and healing, even killing off methicillin-resistant staphylococcus aureus (MRSA).
In addition to being a powerful antimicrobial agent, oregano oil also has anti-inflammatory effects. One study showed that oregano essential oil significantly inhibited several inflammatory biomarkers in skin.
Improvement of Acne
Because of its combined antibacterial and anti-inflammatory properties, oregano oil may help improve the appearance of acne by reducing blemishes. Since using oral antibiotics to treat acne has a range of potential side effects, oregano oil may provide a safe and effective alternative when used topically.
Oregano oil has been found to support healthy cholesterol levels. A study of 48 people who took a small amount of oregano oil after each meal showed a significant reduction in their LDL (or “bad”) cholesterol, which is one of the main causes of the clogged arteries that can lead to heart disease.
Oil of oregano is commonly used to treat digestive problems like belly cramps, bloating, and irritable bowel syndrome, among others. While more research continues, experts have found that oregano is high in carvacrol. This is known to be effective against types of bacteria that cause digestive discomfort.
Oregano Oil Side Effects
Because oregano oil has such potent ingredients, you should consult with your doctor before taking it or any other supplement. Consider the following before using oregano oil either internally or topically:
Because oregano oil is such a powerful antimicrobial agent, it can also be toxic to humans. Taken in large doses, it can even be lethal. Only use the recommended amount of oregano to yield its benefits. Further studies into its toxic effect on humans is needed.
Although oregano oil can help with some skin ailments, like acne, it may irritate sensitive skin. Don’t apply undiluted oregano oil directly to your skin. Patch test any products containing oregano oil to ensure they won’t cause any adverse effects. Additional research on skin irritation caused by it on humans is required.
Research on the effects of oregano oil on someone who is pregnant or breastfeeding has been inconclusive. If you’re pregnant or breastfeeding a baby, it is best to look for an alternative.
Avoid oregano oil if you’re already taking a diuretic, as it may worsen medication side effects. Since oregano has natural diuretic properties, it may interfere with the action of lithium and similar medications.
