Benefits of Oregano
Rich In Antioxidants
Several studies have been done on the high content of antioxidants in oregano, and the total tocopherol content was between 228 ppm to 672 ppm (2). Antioxidants can help fight damage from harmful free radicals. The buildup of free radicals has been linked to chronic diseases, such as cancer and heart disease. Due to the antioxidant activity of tocopherol, oregano has been associated with numerous health benefits, such as reducing the risk of cardiovascular disease, inflammation, and more (3).
An antibacterial property is when a substance, or in this case, an herb, can destroy or suppress the growth and reproduction of bacteria (4). Oregano contains certain compounds that have potent antibacterial properties. One study concluded that Origanum heracleoticum L. might be an effective alternative for antibacterial remedies enhancing the healing process of bacterial infections and preventing the development of antibiotic resistance (5).
An antimicrobial property is when a substance, or in this case, an herb, can kill or suppress the spread of microorganisms such as bacteria, viruses, protozoans, and fungi (6). One study compared the antimicrobial activity of oregano, sage, and thyme essential oils. Oregano was one of the most efficient essential oils against bacteria, second to thyme Studies showed that oregano could help block the growth of Escherichia coli and Pseudomonas aeruginosa (7).
An antiviral property is when a substance, or in this case, an herb, can kill a virus or suppress the virus' ability to replicate, multiply or reproduce (8). In addition to oregano's antibacterial and antimicrobial properties, some studies have found that some components of oregano may also protect against some viruses. In one study, carvacrol inactivated norovirus, a viral infection that causes diarrhea, nausea, and stomach pain, within one hour of treatment (9). Another study found that thymol and carvacrol inactivated 90% of the herpes simplex virus within one hour (10).
Oregano may have anti-inflammatory properties that could improve your overall health. Chronic inflammation has been linked with many diseases, such as type 2 diabetes, asthma, and certain cancers (11). The high antioxidant levels of oregano can help neutralize free radicals, reducing inflammation (12). Oregano contains compounds like carvacrol that have been shown to have anti-inflammatory properties; in one animal study, carvacrol reduced swelling in the paws of mice by up to 57 percent (13). In another animal study, a mixture of thyme and oregano essential oils reduced the number of inflammatory markers in mice with colitis or an inflamed colon (14).
May Prevent & Kill Certain Cancers
Oregano is high in antioxidants, which can neutralize free radical damage and aid in cancer prevention. One study treated human colon cancer cells with oregano extract and found that it stopped the growth of cancer cells and helped kill them off (15). In another study, they concluded that carvacrol, one of the components in oregano, also helped suppress the growth and spread of colon cancer cells (16).
