That's a terrible idea. > Tea tree oil is poisonous when taken internally.[1][4] It may cause drowsiness, confusion, hallucinations, coma, unsteadiness, weakness, vomiting, diarrhea, stomach upset, blood cell abnormalities, and severe rashes. It should be kept away from pets and children.[1] Tea tree oil should not be used in or around the mouth.[2][4] As a test of toxicity by oral intake, the median lethal dose (LD50) in rats is 1.9–2.4 ml/kg.[12] https://en.wikipedia.org/wiki/Tea_tree_oil#Safety https://en.wikipedia.org/wiki/Tea_tree_oil#Safety
