In contrast, what does oil of oregano do for you that makes it so beneficial? Its active ingredients help fight multiple types of harmful pathogens, including bacteria, yeast and fungi.
These studies give hope to people who want to find a way to manage the horrible suffering that accompanies drugs and medical interventions, such as chemotherapy or use of drugs for chronic conditions like arthritis. A study published in the International Journal of Clinical and Experimental Medicine showed that phenols in oil of oregano can help protect against methotrexate toxicity in mice.
By evaluating various markers in the sciatic nerve in mice, it was observed for the first time that carvacrol decreased the pro-inflammatory response in mice being treated by MTX. In addition to its antimicrobial properties, carvacrol also interferences with certain pathways for bacterial iron handling, which helps lower side effects of iron therapy. One study found that a combination of heat, salt and use of essential oils including oregano had inhibitory effects against mycelia of T.
The researchers concluded that thermotherapy combined with essential oils and salt would be promising to treat tinea pedis in a foot bath. Several of the active compounds found in Origanum vulgare can help aid digestion by relaxing the muscles of the GI tract and also helping balance the ratio of good-to-bad bacteria in the gut.
Like menthol, thymol may help relax the soft tissue of the throat and stomach, which can help to decrease GERD, heartburn and discomfort after eating. Because it helps balance bacteria and fights yeast overgrowth, oregano essential oil is also a popular natural treatment for candida and SIBO. Origanum vulgare hinders bacterial replication and can be used similarly to antibiotic medications, such as rifaximin Xifaxan , for treating infections that affect digestive health and nutrient absorption.
When patients diagnosed with SIBO via lactulose breath test were treated either with rifaximin 1, milligrams or herbal antimicrobials over the course of four weeks, the results showed that 46 percent of the patients treated with herbal antimicrobials experienced symptom improvements compared to only 34 percent treated with the antibiotic rifaximin.
Additionally, 14 of the 44 patients who still had SIBO after a course of rifaximin were then treated with herbal antimicrobials. Fifty-seven percent responded positively to the herbal treatment even after failing to feel better from the antibiotics.
One study found that when adults whose stools tested positive for enteric parasites including Blastocystis hominis, which causes digestive distress supplemented with milligrams of oregano for six weeks, many experienced significant improvements in gastrointestinal symptoms. Researchers reported a complete disappearance of Entamoeba hartmanni four cases , Endolimax nana one case and Blastocystis hominis in eight cases.
Gastrointestinal symptoms improved in seven of the 11 patients who tested positive for Blastocystis hominis , which tends to cause symptoms like nausea, gas, bloating and abdominal pain. Oregano retains its strong antioxidant capacity in both fresh and dry form. Due to its high concentration of antioxidants, oregano essential oil has been shown to help reduce oxidative damage and help in preventing mutagenesis, carcinogenesis and aging due its free radical scavenging activities.
Free radicals are believed to be a contributing factor to common chronic conditions, including cancer, cardiovascular diseases, neurodegenerative disorders and drug toxicity. One study found that combined treatment with thyme and oregano essential oils helped reduce the production of pro-inflammatory cytokines and thereby may help attenuat e colitis a type of inflammatory bowel disease in mice.
Other studies show that oregano oil is beneficial for treating reoccurring respiratory disorders, tumor growth and rheumatoid arthritis. Research published in the Journal of International Medical Research suggests that adding oregano oil supplementation can improve cholesterol levels. While oregano oil contains a significant amount, the compound thymol occurs most abundantly in thyme.
For instance, Staphylococcus is a common type of bacteria that causes staph infection. Some strains occur naturally in the body, but when the bacteria grow too quickly, it can cause bothersome symptoms. 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.
Researchers are also exploring the use of oregano oil for antibiotic-resistant bacteria. The authors of a study in Frontiers in Microbiology found that a combination of oregano oil and silver nanoparticles effectively eliminated all the bacteria they 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 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 may be promising.
Research from found thymol to be an effective treatment for common Candida fungal infections. Oregano oil is also a potent antioxidant. Antioxidants help protect the body from damage caused by oxidative stress and free radicals. Oxidative stress may lead to increased DNA damage and cell death. 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. Some sources claim that oregano oil may help reduce inflammation. The compound carvacrol shows anti-inflammatory effects in both animal models and in vitro studies.
In one study on mice, the compound prevented obesity by affecting the genes involved in inflammation. In another animal study, the compound reduced swelling. While the results show promise, the researchers have called for more tests on humans to determine a safe dosage. 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.
Both carvacrol and thymol may be effective insect-repellents. In , 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.
Oregano oil extract is an herbal supplement. Oregano oil is also available as a highly concentrated essential oil that comes in liquid form. The oil may come premixed with a carrier oil or it may be purchased full strength. The usual recipe is 5 to 6 drops for every ounce of carrier oil. Some essential oils are toxic and qualities vary. Oregano essential oil can also be used in steam, as a vapor to be inhaled. This is done by putting one or two drops in a vaporizer or bowl of steaming water.
Most of the research done to date on oregano has been in the form of in vitro laboratory studies, animal studies, or small human trials.
Even so, this product is marketed for many uses. Unlike the herb you cook with, commercially-prepared oregano oil is highly concentrated. When used as directed, oregano oil should be safe. In too-high doses, it may have detrimental effects. This may be due in part to thymol, one of the phenols it contains. In high doses, thymol is a mild irritant which might affect the skin or internal organs.
It can cause:. Thymol may also be irritating or corrosive to the skin and eyes. Oregano oil should never be applied to broken skin or used on or near the eyes. Oregano oil may cause an allergic reaction in some people.
Commercially-sold supplements and essential oils have recommended doses, established by their manufacturers. These take the amount of thymol and other phenols into account. When using oregano essential oil, a little goes a very long way. One to two drops of diluted oil may not seem like much, but exceeding that dosage may cause adverse reactions to occur.
