James Thurber: I loathe the expression What makes him tick. It is the American mind, looking for simple and singular solution, that uses the foolish expression. A person not only ticks, he also chimes and strikes the hour, falls and breaks and has to be put together again, and sometimes stops like an electric clock in a thunderstorm.
But watch out, this is a liquid you want to keep far away from your mouth. Tea tree oil is dangerous if taken by mouth. It can cause serious side effects such as confusion, inability to walk, unsteadiness, rash and coma, says board-certified dermatologist Dr. Janet Prystowsky.
Since tea tree oil is a bit oily, most people will not want to apply it directly to their skin, except perhaps at bed time, as it does have moisturizing properties too. It can be used as a facial cleanser. You can simply dilute a few drops with distilled water, and then use a cotton puff to apply to your face.
