Yaupon Holly
Ilex vomitoria
Ilex vomitoria, commonly known as Yaupon holly, is a shrub native to the southeastern United States. While traditionally used by some indigenous peoples for ritual purposes and as a stimulant, no specific traditional uses are recorded in historical literature or modern practices. Scientific evidence suggests that among several Ilex species tested, two native Ilex species and Camellia sinensis demonstrated reduced susceptibility to tea scale infestation, indicating potential biopesticidal properties. The presence of methylxanthines like caffeine and theobromine in American White Ibis liver samples has been noted but could not be definitively linked to Ilex vomitoria. Seasonal variations in antioxidant capacity have been observed, with spring leaves showing higher flavonoid and polyphenol content than other seasons. No major safety issues or drug interactions have been reported for this plant.

What the science says
- The study found that among six Ilex and Camellia species, two native Ilex species and C. sinensis showed reduced susceptibility to tea scale infestation.
- The study found that methylxanthines, including caffeine and theobromine, were detected in American White Ibis liver samples, but the source could not be definitively identified.
- Thicketization of oak woodlands appears to significantly reduce deep drainage and groundwater recharge in Post Oak Savannas.
- The antioxidant capacity of Ilex vomitoria leaves varies seasonally, with spring leaves showing the strongest activity due to higher content of flavonoids and polyphenols.
