Chaparral is most commonly used for treating cancers, rheumatic pain, generalized pain, arthritis, and skin diseases. It contains a constituent called nordihydroquaiaretic acid (NDGA), which has antioxidant and anti-cancer effects. Chaparral is also used as a mouthwash.

Larrea tridentata (Sesse & Moc. ex DC.) Coville

Introduction
Now found throughout the Southwestern US, chaparral actually
originated in Argentina several thousand years ago. The stems and leaves
of the bush are covered with a sticky resin that screens leaves against
ultraviolet radiation, reduces water loss, and poisons or repels most
herbivores. This resin is used in herbal medicine and to protect wood
from insects. It received its name "creosote bush" due to the smell that
comes from it when it rains. Its extremely bitter taste keeps it safe
from animals that would otherwise graze upon it. It is also regarded as
one of the most adaptable desert plants in the world; it was one of the
first to grow back in Yucca Flats after the 1962 nuclear bomb tests done
there.
