Chaparral Overview

Chaparral Chaparral, also known as creosote bush, is a type of flowering shrub that is native to the southwestern United States and parts of Mexico. It is characterized by its small, yellow flowers and its ability to grow in dry, desert climates. The leaves of the chaparral plant contain a number of chemical compounds and the plant is sometimes used as a natural remedy for pain, inflammation, and other health problems. It is important to note that chaparral has been linked to rare cases of kidney and liver toxicity. Due to this, the U.S. Food and Drug Administration (FDA) has advised individuals against taking products containing chaparral.
