I found this information in the book Fifty Animals that Changed the Course of History by Eric Chaline on page 66. This was an interesting book; it talked about animals you would never have thought were beneficial to us.
The book A Perfect Red by Amy Butler Greenfield recounts the colorful history of cochineal dye and the quest by many world powers to obtain their own supplies of this beautiful dye.
You would be amazed at the amount of insects, animals and plants we are exposed to everyday. Nature in Cosmetics and Skin Care by Cyrille Corbeil will simultaneously surprise and disgust you.
