Manzanita is a common name for many species of the genus Arctostaphylos. They are evergreen shrubs or small trees present in the chaparral biome of western North America, where they occur from Southern British Columbia and Washington to Oregon, California, Utah, Arizona, New Mexico, and Texas in the United States, and throughout Mexico. Manzanitas can live in places with poor soil and little water. They are characterized by smooth orange or red bark and stiff, twisting branches. There are 105 species and subspecies of manzanita, 95 of which are found in the Mediterranean climate and colder mountainous regions of California, ranging from ground-hugging coastal and mountain species to small trees up to 20 feet (6m) tall. Manzanitas bloom from winter to early spring and carry berries in spring and summer. The berries and flowers of most species are edible. The word manzanita is the Spanish diminutive of manzana (apple). A literal translation would be little apple. The name manzanita is also sometimes used to refer to species in the related genus Arbutus, which is known by that name in the Canadian area of the tree's range, but is more usually known as madroño, or madrone in the United States. Native Americans in Northern California make a tisane from manzanita leaves to treat poison oak rash. The leaves contain chemicals with a mildly disinfectant quality and can be used for mild urinary tract infections. The tree's berries can be turned into a cider by mashing, pouring an equal amount of water over the paste, and then straining it. In Native American cultures, this cider is then used to treat stomach ailments and promote appetite. The berries have also been used to treat bronchitis and kidney problems. The leaves of the manzanita also have many medicinal purposes. Chewing the leaves of the manzanita tree into a poultice can treat open sores and ease headaches after application. Chewing on the leaves, without ingestion, can cure stomach issues such as cramps and aches. Infusions of the leaves can also treat ailments such as diarrhea and severe colds.
