Much of the information regarding the toxicity of Essential Oils is passed along from research that may or may not have been done with Essential Oils themselves. However, with the lack of better information, it is probably wise to exercise caution with oils that are considered toxic. The affects of toxicity from Essential Oils are of a longer term nature and do not manifest themselves immediately. Our bodies have the natural ability to rid itself of toxins, yet if a toxin is repeatedly brought into the body it can break down our natural systems and cause a build-up of any harmful substance. To be safe, only use toxic oils sparingly and do not use them continuously over long periods of time.

The toxicity of a chemical can be measured using a of animal studies. OSHA uses three categories for this: Oral LD50 - Lethal dose 50% test. The medium lethal dose (LD50) that kills 50% of lab animals receiving it. Oral LD50 is expressed as milligrams of chemical per kilogram (mg/kg) of test animals body weight, or 1 millionth of the test animal's body weight. OSHA considers a chemical to be toxic if the oral LD50 is between 50 mg/kg and 500 mg/kg. Skin LD50 - A dose that kills 50% of lab animals that had concentrations applied directly to their bare skin for 24 hours. Skin LD50 is also expressed in mg/kg, and the OSHA considers a chemical to be toxic if the LD50 is between 200 mg/kg and 1000 mg/kg. Inhalation LC50 - Lethal concentration 50% is the concentration of a chemical in the air needed to kill 50% of lab animals that breathed it. LC50 is expressed in parts per million (ppm) for bases and vapors, and milligrams/liter (mg/l) for mists, fumes and dusts.
Excessive amount of toxins, drugs, and chemical substances in the body.

in medical treatment, the harmful effects of a medication or treatment, especially at higher doses.
The degree to which a substance or mixture of substances can harm humans or animals. Acute toxicity involves harmful effects in an organism through a single or short-term exposure. Chronic toxicity is the ability of a substance or mixture of substances to cause harmful effects over an extended period, usually upon repeated or continuous exposure sometimes lasting for the entire life of the exposed organism. Subchronic toxicity is the ability of the substance to cause effects for more than one year but less than the lifetime of the exposed organism.

Toxicity is a measure of the degree to which something is toxic or poisonous. The study of poisons is known as toxicology. Toxicity can refer to the effect on a whole organism, such as a human or a bacterium or a plant, or to a substructure, such as a cell (cytotoxicity) or the liver (hepatotoxicity).
