A Creosote bush is a form of shrub native to Arrakis. It required very little water, and was capable of digging deep into sand dunes to find it. It has Shallow roots to catch rain, it also has bad odour to repel animals and poison at the bottom of the trunk. The bush also has shiny leaves to catch and hold water. When the Fremen of Arrakis needed to perform delicate work with their hands, they would often remove the gloves from their stillsuits and rub their hands with leaves from the creosote bush. This would help prevent perspiration through the hands.
