Creosote Bush

Larrea tridentata

Long before it had a Latin name, creosote bush was one of the most relied-upon plants of the Sonoran, Mojave, and Chihuahuan deserts. The Tohono O'odham, Akimel O'odham, Cahuilla, and other Southwestern nations gathered its resin-coated leaves and stems to make washes and poultices applied to the skin for cuts, sores, insect bites, and aching joints, and burned or steeped the branches for their sharp, cleansing aroma. The dark resin itself had practical value too, used as a glue and a waterproofing agent for baskets and pottery. It is a plant woven into desert life for thousands of years, valued as much for its resilience as for its uses.

Safety.

Creosote bush, sold in stores as chaparral, carries a real and well-documented risk when taken internally: case reports link ingested chaparral to serious liver injury, including hepatitis and, in rare cases, liver failure requiring transplant. Because of this, the FDA issued a public warning decades ago advising against internal use, and it should not be taken as a tea, tincture, capsule, or any other internal preparation. It should be avoided entirely during pregnancy and breastfeeding, by anyone with existing liver or kidney conditions, and by anyone taking medications processed by the liver. Even topical use has been known to cause allergic skin reactions in sensitive individuals, so a small patch test is wise before broader use. Please talk with a qualified healthcare provider before using this plant in any form.
