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.]
Because this essential oil poses a higher risk of causing irritation and sensitization, it is recommended that it be avoided in the bath, even if it is solubilized/diluted.
General Safety Information
