Chaparral herb plan:Larrea tridentata

Posted by Bangzkie Thursday, February 16, 2012

Larrea tridentata is known as Creosote bush as a plant, chaparral as a medicinal herb,and as "gobernadora" in Mexico, Spanish for "governess," due to its ability to secure more water by inhibiting the growth of nearby plants. In Sonora, it is more commonly called "hediondilla." It is a flowering plant in the family Zygophyllaceae. The species is named after J.A. Hernandez de Larrea, a Spanish clergyman.

Information:Larrea tridentata is an evergreen shrub growing to 1 to 3 metres (3.3 to 9.8 ft) tall, rarely 4 metres (13 ft). The stems of the plant bear resinous, dark green leaves with two opposite lanceolate leaflets joined at the base, with a deciduous awn between them, each leaflet 7 to 18 millimetres (0.28 to 0.71 in) long and 4 to 8.5 millimetres (0.16 to 0.33 in) broad. The flowers are up to 25 millimetres (0.98 in) in diameter, with five yellow petals. Galls may form by the activity of the creosote gall midge. The whole plant exhibits a characteristic odor of creosote, from which the common name derives.

Medicinal use:Larrea tridentata was used by Native Americans in the Southwest as a treatment for many maladies, including sexually transmitted diseases, tuberculosis, chicken pox, dysmenorrhea, and snakebite. The shrub is still widely used as a medicine in Mexico. It contains nordihydroguaiaretic acid.

supplements and toxicity Larrea tridentata is often referred to as chaparral when used as a herbal remedy and supplement. The United States Food and Drug Administration has issued warnings about the health hazards of ingesting chaparral or using it as an internal medicine, and discourages its use.In 2005, Health Canada issued a warning to consumers to avoid using the leaves of Larrea species because of the risk of damage to the liver and kidneys.Althogh the plant has been marketed as "Chaparral Tea" as a cure-all in health food stores, the plant does not grow in true chaparral vegetation.
