Ingesting foothill camas bulbs caused illness in eight adults, requiring supportive care for some. Symptoms included nausea, vomiting, and bradycardia, with no specific antidote available for this plant poisoning.

Area of Science:

  • Toxicology
  • Botany
  • Emergency Medicine

Background:

  • Accidental ingestion of wild plants can lead to significant toxicity.
  • Foothill camas (Zigadenus paniculatus) is a toxic plant found in Utah.
  • Misidentification of wild edibles poses a public health risk.

Observation:

  • Eight adults consumed foothill camas bulbs, mistaking them for edible species.
  • All individuals experienced adverse health effects following ingestion.
  • Three patients required hospitalization for medical support.

Findings:

  • Common symptoms included nausea, vomiting, and abdominal pain.
  • More severe signs observed were dizziness, near syncope, hypotension, and bradycardia.
  • No specific antidote exists for Zigadenus species poisoning.

Implications:

  • Prompt supportive care is crucial for managing foothill camas toxicity.
  • Atropine may be beneficial for treating symptomatic bradycardia and hypotension.
  • Public education on identifying toxic versus edible wild plants is essential to prevent future poisonings.
