MORE THAN TASTE.

There are various health benefits of oregano oil. These include helping fight certain types of bacteria, acting as an antifungal agent, and reducing inflammation.

This oil is available to use orally, unlike oregano essential oil, which is much more concentrated and used in aromatherapy. People should not take essential oils by mouth. Whether a person applies it topically or takes an oral supplement, oregano oil may be helpful for a range of conditions. Compounds in the oil have effective antioxidant and antimicrobial properties, which explain many of the  health benefits.

Oregano, or Origanum vulgare, is a small, bushy plant that belongs to the mint family. It is a familiar culinary herb in Italian dishes. Oregano oil contains high levels of important compounds in its leaves and smaller stems. Oil manufacturers dry the leaves and stems, then steam-distill the plant matter to extract as many compounds as possible.

Oregano oil contains: carvacrol, the main active compound in oregano oil and a type of antioxidant called a phenol. Thymol, which may help protect against toxins and fight fungal infections

While oregano oil contains a significant amount, the compound thymol occurs most abundantly in thyme.

Due to the high levels of carvacrol, oregano oil may help fight certain types of bacteria. Research shows that carvacrol is effective in eliminating the bacteria Staphylococcus aureus and Staphylococcus epidermidis, two common causes of infection. Taking oregano oil supplements or rubbing it on the skin may help a person make use of these antibacterial effects.

Studies found that a combination of oregano oil and silver nanoparticles effectively eliminated all the bacteria researchers tested.

Oregano oil may help treat chronic bacterial issues, such as SIBO. People with SIBO experience gastrointestinal problems due to an overgrowth of certain bacteria in their intestines.

A 2014 study found that herbal remedies, including one that contained high levels of both carvacrol and thymol, were effective tools in treating SIBO.  Exploring the individual effects of each compound will require more research, but these initial findings are promising.

 Treating fungal infections

Oregano oil also appears to be a potent antifungal agent thanks to high levels of thymol. Research from 2015 found thymol to be an effective treatment for common Candida fungal infections. Candida causes several types of infections, including: oral thrush, yeast infections, infected toenails or fingernails, and athlete’s foot.

Providing antioxidants : Oregano oil is also a potent antioxidant. Antioxidants help protect the body from damage caused by oxidative stress and free radicals.

Oxidative stress leads to cellular death and DNA damage  Oxidation may also play a role in other issues, such as arthritis, atherosclerosis, and some cancers.

Thymol and carvacrol are powerful antioxidants that may help reduce oxidation. The researchers suggested that further studies explore safe doses for regular use. 

Reducing inflammation :estSome sources claim that oregano oil may help reduce inflammation, The compound carvacrol shows anti-inflammatory effects in both animal models and in vitro studies.  Research from 2017  looked at a variety of investigations into carvacrol’s anti-inflammatory effects. In one study on mice, the compound prevented obesity by affecting the genes involved in inflammation. In another animal study, the compound reduced swelling.

 Healing wounds : Applying diluted oregano oil to the skin may help protect smaller cuts and scrapes on the skin as they heal. Compounds such as thymol and carvacrol could protect these types of wound from bacterial infections.

 Repelling insects : Both carvacrol and thymol may be effective insect-repellents. In 2017, researchers found that these compounds repelled some ticks and mosquitos. The research included test tube studies and those with human participants. More research will help confirm this potential benefit, but rubbing diluted oregano oil on the skin may be a natural way to help repel insects.

 Relieving pain: There is some evidence that oregano may be an effective pain reliever. An animal  found that an extract of oregano provided pain relief. These results were dose-dependent — the more the animals took, the more pain relief they felt. Importantly, the researchers used a water-based extract, so the oil may not provide the same results. More research in humans could help determine an appropriate dose.

 Aiding weight loss: Oregano oil may also be a helpful tool for people looking to lose weight. Researchers  have found that carvacrol, the main compound in oregano oil, disrupts part of the process that leads to the creation and accumulation of fat tissue.

Fighting cancer: Some sources claim that oregano oil may help fight some cancers. One review  notes that the essential oil from oregano helps prevent some types of colon and breast cancer from growing in test tubes.

The oil also appeared to inhibit the growth of some lung cancer and prostate cancer cells. Much of the research in cancer comes from test tubes or animal models, so people should view the results with caution and never use oils as a replacement for medical treatment.

To use oregano oil topically for skin issues, dilute one or two drops into a teaspoon of carrier oil in the palm of your hand. A person can then apply this mixture directly to the skin. Do not use oregano oil on children , infants or pregnant or breastfeeding women.

Oregano oil can interfere with some medications, including lithium and diuretics. Also, it is possible to be allergic to the oil.

Oregano oil should not be consumed in the essential oil form. This can cause abdominal discomfort, nausea, vomiting, dizziness, and headache.

A person can consume oregano oil extract as a supplement in pill or capsule form or by consuming it with a meal. One mouse study found oregano essential oil stopped bacterial growth in burn wounds. However, it is not currently advised to use oregano essential oil as an antibiotic in a clinical setting. More research is needed on this topic.

Oregano oil is potentially good for lung health. One animal study found that oregano oil appeared to inhibit the growth of some lung cancer cells in a petri dish. More recent research showed some promise that wild oregano essential oil has an inhibitory effect on certain bacteria known to cause pneumonia.

Oregano essential oil may offer antibacterial, antifungal, and anti-inflammatory benefits. Researchers are also exploring its potential use for wound healing, weight loss, and pain relief.

Oregano oil is powerful and may help with a range of issues. While it can, for example, be an antimicrobial remedy, it should not replace medical treatment.

Be careful to use oregano oil and not oregano essential oil, which is much stronger and not safe to consume.

Verifying many claims about oregano oil requires more extensive research on humans.
