Poisonous Plant – Yaupon, Yaupon Holly
Aquifoliaceae (Ilex vomitoria)
Identification: Yaupon is an evergreen holly that resembles a shrub and has glossy, green leaves with pointed tips. Simple, alternating leaves with shallow teeth. Small white blossoms on a bush give rise to scarlet berries.
Habitat: coastal plant that is commonly farmed and found in Texas and the Southwest.
Triterpenoids, saponic glycosides, and illicin are among the poisons that make berries hazardous and inedible.
Symptoms include nausea, vomiting, and diarrhea due to mild poisoning.
First Aid: disease progresses naturally and self-limits.
Note: colors are made from berries and leaves. Alum mordant is dyed red by the juicy red berries. Use it on wool by soaking it in the dye and allowing it to absorb the color in the sunshine. To attain a gray hue, pound leaves in water containing iron or copper. Young leaves can be consumed or used to make tea.
