Larrea species

The lipophilic material found on the surface of Larrea species (Zygophyllaceae) is comprised of several methylated flav-onoid aglycones and lignans such as nordihydroguaiaretic acid. 

The lipophilic material found on the surface of Larrea species (Zygophyllaceae) is composed of several methylated flavonoid aglycones and lignans such as nordihydroguaiare-tic acid see Chapter 8). This resinous material was shown to act as an antiherbivore substance and appeared to reduce digestibility of the plant for several herbivores (Seigler, 1983).

In short, the other species of greasewood are to be distinguished from the Wyoming species. For example, the common evergreen greasewood or creosote bush or chaparral of the American Southwest is an entirely different species, which has been called Larrea mexicana, but more usually is called Larrea tridentata or Larrea divaricata. Yet, other species are also called greasewood. 

On page 682 of Hartwell s book there is a citation for the species Larrea tridentata of the family Zygophyllaceae. This is the common creosote bush, or greasewood, or chaparral of the desertlike regions of the Southwest. It is reported in the praiul-timate column of Hartwell s compilation that a tea made from the leaves and stems of this plant may cure stomach cancer, hver cancer, leukemia, lung cancer, and kidney cancer. This information is buried in the central files of the National Cancer Institute. 

There are, however, differmt species of Larrea the creosote bush. In the work by Percy Train et al. on the Paiute Indians of Nevada, previously cited, another species or subspecies designated Larrea divaricata was used by these Indians, but was not mentioned specifically as a treatment for cancers or tumors, but was instead used for other diseases. 

California and Texas) also central Mexico. Clones known to live 10,(XX) -I- years longer than any other plants (hickman). Larrea is represented by five species (one North American four South American) cytologically distinct L. tridentata populations in the Sonoran, Chihuahuan, and Mojave deserts often considered conspecific with South American L. di-varicata Cav. Parts used are leaves and stems.
