Hi. This is what Toxbase (national poisons information service tool) says about olbas oil:-
Toxicity
Highly toxic, both on account of the essential oil content and, to a lesser extent, the wintergreen (methyl salicylate).
Undiluted oils in the eye may cause intense irritation and corneal damage.
Ingestion may cause a burning sensation in the mouth and throat, hypersalivation, nausea, vomiting and diarrhoea. Haematemesis may occur. Volatile oils may be aspirated into the lungs causing pulmonary complications.
Systemic features may be delayed up to 4 hours after ingestion and include ataxia, dizziness, headache, drowsiness, excitement, delirium, respiratory depression, convulsions and coma. Hypotension and tachycardia have been reported.
LOTS OF OTHER NASTY STUFF TOO! BUT patient must have drunk some, but does not specify the amount. 'Childrens Olbas oil' has the same formulation and same toxicity!
