Cedar Oil is distilled from the foliage and sometimes wood and roots of the Juniperus Virginiana Cedar Trees that grow in Texas and Oklahoma. Ancient Egyptians used the oil from cedarwood trees in the embalming process which kept insects from disturbing the body.  Today Cedar Oil is used as an insect repellent, either directly applied to skin or added to sprays.  Cedar Oil is one of the quality ingredients in natural, all-purpose Goodwinol Shampoo for cats and dogs.  The clean, bright scent stops odors and keeps coats smelling fresh between baths. The shampoo leaves coats lustrous and shiny without the use of conditioners. It lathers well and is gentle and safe for kittens and puppies when they are six weeks old.   http://www.goodwinol.com/
