Ilex vomitoria

 ( Vomitoria ) 

Ilex vomitoria, commonly known as yaupon () or yaupon holly, is a species of holly that is native to southeastern North America. The word yaupon was derived from the Catawban yą́pą, from yą- tree + pą leaf. Another common name, cassina, was borrowed from Timucua language

(despite this, it usually refers to Ilex cassine). The Latin name was given by early European observers who misunderstood Indigenous purification ceremonies—where vomiting was part of the ritual—and incorrectly assumed that the plant itself was emetic.

The plant was traditionally used by Native Americans and Euro-American colonists to make an infusion containing caffeine and theobromine. This drink went by different names, such as Yaupon tea among natives and "Carolina tea", or "South Seas tea" among colonists. Today, it is also known as yaupon tea. It is one of only two known plants endemic to North America that produce caffeine. The other (containing 80% less) is Ilex cassine, commonly known as dahoon holly. In the 21st century, the plant has begun to be harvested for making commercial tea once again in the United States.Folch C.

Description Yaupon holly is an evergreen shrub or small tree reaching 5–9 Metre tall, with smooth, light gray bark and slender, hairy shoots. The Phyllotaxis is alternate, with leaves ovate to elliptical and a rounded apex with Crenation or coarsely serrated margin, 1–4.5 cm long and 1–2 cm broad, glossy dark green above, slightly paler below. The are 5–5.5 mm diameter, with a white four-lobed corolla. The fruit is a small round, shiny, and red (occasionally yellow) drupe 4–6 mm diameter containing four pits, which are dispersed by birds eating the fruit. The species may be distinguished from the similar Ilex cassine by its smaller leaves with a rounded, not acute apex.

Habitat and range

I. vomitoria occurs in the United States from the Eastern Shore of Virginia south to Florida and west to Oklahoma and Texas. A disjunct population occurs in the Mexico state of Chiapas. It generally occurs in coastal areas in well-drained, sandy soils, and can be found on the upper edges of brackish and , sandy hammocks, coastal , inner-dune depressions, , maritime forests, nontidal forested wetlands, well-drained forests, and pine .

Ecology

The fruit are an important food for many birds, including the Florida duck, American black duck, mourning dove, ruffed grouse, bobwhite quail, wild turkey, northern flicker, , cedar waxwing, eastern bluebird, American robin, grey catbird, northern mockingbird, and white-throated sparrow. Mammals that eat the fruit include nine-banded armadillo, American black bear, gray fox, raccoon, and skunk. The foliage and twigs are browsed by white-tailed deer.

Cultivation and uses

Human consumption

Some Native American tribes, particularly in the Southeast, brewed the leaves and stems of Yaupon to make a ceremonial beverage known as the "black drink." These rituals often involved vomiting as a form of spiritual or physical purification—not because the plant itself was emetic. Early European observers misunderstood this practice and mistakenly concluded that Yaupon caused vomiting, hence the Botanical name - Ilex vomitoria. In reality, the active compounds in Yaupon—caffeine, theobromine, and theophylline—are the same as those found in its South American relatives, yerba mate and guayusa.

Any vomiting likely resulted from the ceremonial context, which involved drinking large volumes while fasting, rather than from the plant's inherent properties.Hudson, Charles M. (1976). The Southeastern Indians. University of Tennessee Press .

Some theorize that Native Americans may have also used the infusion as a laxative.

Ilex vomitoria usage by colonists for tea making and for medicinal uses in the Carolinas is documented by the early 18th century. In the English-speaking colonies, it was known variously as cassina, yaupon tea, Indian tea, Carolina tea, and Appalachian tea. In the 21st century, the process of drying the leaves for consumption has gained newfound popularity, and yaupon is now commercially available.

Ornamental

Ilex vomitoria is a common landscape plant in the Southeastern United States. The most common cultivars are slow-growing shrubs popular for their dense, evergreen foliage and their adaptability to pruning into of various shapes. These include:

• 'Folsom Weeping' – weeping cultivar
• 'Grey's Littleleaf'/'Grey's Weeping' – weeping cultivar
• 'Nana'/'Compacta' – dwarf female clone usually remaining below 1 m in height
• 'Pride of Houston' – female clone similar to type but featuring improvements in form, fruiting, and foliage
• 'Schilling's Dwarf'/'Stokes Dwarf' – dwarf male clone that grows no more than 0.6 m tall and 1.2 m wide
