Re: Toxic List for our Birds.

Hope this helps

Tea tree oil is toxic, to both humans and pets, if taken orally. In Australia 100 percent tree tea oil is categorized as a schedule 6 toxin. Packaging there requires child-proof containers and cautionary labeling. Such packaging and labeling are not necessary in the U.S. and Canada. A 10 year long veterinary study of tea tree oil toxicity in pets found that 89 percent of owners who used 100 percent oil assumed that it was safe. The researches felt that the lack of labeling was a major reason for the feeling of safety on the part of American pet owners.

Tea Tree Oil Toxicity for Pets

Tea tree oil contains various types of chemicals called terpenes. These are the chemicals that make the oil effective against bacteria and fungi. They are also the toxic agent. Terpenes are rapidly absorbed into the body whether taken orally or on the skin. This means topical application of concentrated oil can result in the same toxicity as accidental oral ingestion. Given the tendency of pets to groom, especially cats, the toxicity risk of topical applications is amplified.

Symptoms of toxicity vary depending on the dose of terpenes ingested. Minor symptoms like drooling or vomiting may be found with mild doses of oil. Animals with moderate illness may appear weak, have difficulty walking, or seem partially paralyzed. Severely ill animals have life-threating symptoms like tremors, seizures, greatly reduced level of consciousness, or coma. Symptoms follow 2 to 12 hours after exposure.

Treatment for Tea Tree Oil Toxicity in Pets

There is no antidote for terpenes. Treatment is based on the level of toxicity. Mild illness may only require skin decontamination with dish soap bathing. Inducing vomiting is not recommended. The neurological effects of the terpenes, as well as the thick quality of the oil, increase the risk of aspiration pneumonia if vomiting is induced.

The effectiveness of orally administered activated charcoal in binding terpenes after oral ingestion of tea tree oil is unknown. Vomiting control with medications is necessary before administering activated charcoal. Activated charcoal should not be given to pets with severe symptoms due to the risk of aspiration of the charcoal liquid.

Skin decontamination and support therapy with intravenous fluids is the standard treatment. Vomiting, muscle tremors, and seizures are treated with medications as needed. Treatment may be necessary for up to 72 hours after exposure. Terpenes are toxic to the liver so the use of liver protectants like SAM-e and silymarin (milk thistle) for two weeks is also recommended.

Prevention of Tea Tree Oil Poisoning in Pets

Although tea tree oil is effective in treating certain skin conditions in pets, it has not been proven to be superior to other traditional medications. In fact, the concentrations of tea tree oil suggested for many skin problems far exceed the concentrations found in most pet products (.1%-1%). The attraction of using a natural product as opposed to a man-made synthetic treatment may not be worth the risk. The use of dilutions of 100 percent tea tree oil should be avoided in pets. It is too easy to miscalculate the amount of oil to use. Finally, oil should be safely stored away from pet access, especially the ingenious, inquisitive cat.
