Safety & Contraindications
Class 2d. Contraindicated in inflammatory diseases of the bile duct, GI tract, and liver. Do not use near nostrils of infants. CAN cautions that the oil can cause nausea and vomiting, and should not be taken internally during pregnancy or lactation. “Undiluted eucalyptus oil is toxic and should not be taken internally unless suitably diluted. A dose of 3.5 ml has proved fatal.” Symptoms of poisoning include abdominal pain, bronchospasm, convulsions, cyanosis, delirium, dizziness, epigastric burning, myosis, muscular weakness, respiratory problems, spontaneous vomiting, tachypnea with severe respiratory depression, and a feeling of suffocation. May interfere with hypoglycemic therapy. Eucalyptus oil causes induction of the foreign-substance degrading enzyme system in the liver. This may weaken and/or shorten the activity of other medicinal agents; may cause diarrhea, nausea, and vomiting. CNS effects include diminution or loss of reflexes and depression of consciousness, possibly progressing to coma. Fatalities have been reported in adults ingesting as little as 4–5 ml eucalyptus oil; 30 ml will usually cause death.
