Oregano Essential Oil Safety Information
Tisserand and Young warn that Oregano Essential Oil is contraindicated during pregnancy and breastfeeding. They indicate that when using Oregano Oil, there is moderate risk for mucous membrane irritation, it may inhibit blood clotting and pose a drug interaction hazard. It may cause embryotoxicity. There is a moderate risk of skin sensitization, and Tisserand and Young recommend a dermal maximum of 1.1%. They advise not to use topically on children age 2 or younger or for those with hypersensitive/diseased/damaged skin. Reading Tisserand and Young's full profile is recommended. [Robert Tisserand and Rodney Young, Essential Oil Safety (Second Edition. United Kingdom: Churchill Livingstone Elsevier, 2014), 376.]
This essential oil poses a higher risk of causing irritation and sensitization when used in the bath. Avoid using it in the bath, even if it is solubilized/diluted.
Oregano CO2 Supercritical Select Extract
In addition to being available as an essential oil, this botanical is available from a small number of reputable sources as a CO2 extract. CO2 extracts offer many advantages. However, they can have differing safety precautions than essential oils because the natural chemistry of CO2 extracts can differ from their essential oil counterparts. Not much safety information is documented from trusted sources for CO2 extracts. Use CO2 extracts with great care and do not assume that every CO2 extract has the same safety precautions as its essential oil counterpart.
General Safety Information
Do not take any oils internally and do not apply undiluted essential oils, absolutes, CO2s or other concentrated essences onto the skin without advanced essential oil knowledge or consultation from a qualified aromatherapy practitioner. For general dilution information, read AromaWeb's Guide to Diluting Essential Oils. If you are pregnant, epileptic, have liver damage, have cancer, or have any other medical problem, use oils only under the proper guidance of a qualified aromatherapy practitioner. Use extreme caution when using oils with children and be sure to first read the recommended dilution ratios for children. Consult a qualified aromatherapy practitioner before using oils with children, the elderly, if you have medical issues or are taking medications. Before using this or any essential oil, carefully read AromaWeb's Essential Oil Safety Information page. For in-depth information on oil safety issues, read Essential Oil Safety by Robert Tisserand and Rodney Young.
