Carvacrol is a chemical that contains warming properties. In earlier studies, the essential oils from thyme and origanum exhibited high MIC values in a range of 256–512 μg/ml against group A Streptococci (GAS) (Magi et al. Similar, trend was observed, with the positive control chlorhexidine digluconate wherein a 2.9, 3.3 and 2.1 folds increase in the expression of ymcA, autolysin AtlE, and sodA genes, respectively was observed at a concentration of 1 µg/ml. If you are applying the oil topically, make sure that you dilute it well with a suitable carrier oil. Results presented in this study strongly suggest that thymol and carvacrol exhibit significant antimicrobial and antibiofilm activities against S. mutans.

The biofilms were stained with the fumes of 1% OsO4 at room temperature for 3 h and were rinsed three times with milli-Q. In other study, carvacrol was added to chitosan-based films for active packaging and its antimicrobial efficiency against food spoilage microorganisms was demonstrated by using a headspace chromatographic technique [21]. This increase in the expression of AtlE gene suggests that exposure to thymol and carvacrol induces apoptosis-like activity. Chlorhexidine digluconate was added to final concentrations of 10.0, 5.0 and 0 µg/ml as a positive control. Thymol and carvacrol are active ingredients of family Lamiaceae; these components have antibacterial and antifungal effects. The terpenes found in thyme oil– carvacrol, thymol, linalool, cineol, camphor, and borneol — have been found to have a wide variety of health benefits. 800-638-3030 (within USA), 301-223-2300 (international).

The change in bacterial viability after treatment with test compounds was determined using MTT assay as described by Mshana et al. The researchers credited its protective effect to the presence of carvacrol. (8) Studies have showed that extracts containing carvacrol and thymol can help to bring blood sugar levels under control. Herbal remedies containing carvacrol have been approved in the the former Soviet country – Georgia as a therapy for blood sugar irregularities. Since these compounds are derived from edible plants classified as GRAS, these essential oils can be used in mouthwashes or toothpastes for controlling oral bacteria and for maintaining good oral hygiene.

Hence, thymol and carvacrol in addition to possessing desired antimicrobial activity also have known health benefits making these essential oils a promising alternative antimicrobial agent. Khan, S.T., Khan, M., Ahmad, J. et al. The antimicrobial activity of thymol and carvacrol have been reported against foodborne pathogens such as Clostridium perfringens, Escherichia coli O157:H7 and Listeria innocua (Du et al. 2015).

Please consult a healthcare practitioner before making changes to your diet or taking supplements that may interfere with medications. The major components in the essential oils of Origanum and Thymus are the phenolic monoterpene carvacrol and its isomeric form Thymol (Chorianopoulos et al. But the commercialization of these plant-based products is often hampered by the inability to purify bioactive compounds from these plants. For immediate assistance, contact Customer Service: sipyleus BOISS. The mechanism behind this antibacterial activity includes permeabilization and depolarization of the cytoplasmic membrane, by reducing the pH gradient across the cytoplasmic membrane.

Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. In order to isolate major components, essential oils of Saudi origanum and Jordanian origanum were subjected to preparative thin layer chromatography (pTLC) using chloroform (100%) as developing solvent to give pure compounds M-1 and M-2 from oils of Saudi origanum and Jordanian origanum respectively. The IC50 values of carvacrol (M-1) and thymol (M-2) against S. mutans were 65 and 54 µg/ml, respectively. Live and dead staining and the MTT assays reveal that a concentration of 100 µg/ml of these compounds reduced the viability and the metabolic activity of S. mutans by more than 50%.
