Area of Science:

  • Dermatology
  • Ethnobotany
  • Toxicology

Background:

  • Ceratocephalus falcatus (L.) Pers. (Ranunculaceae) is a wild plant found in the Van province.
  • The Ceratocephalus genus contains ranunculin, a glycoside known for irritant properties.

Observation:

  • Three patients presented with severe irritant contact dermatitis.
  • The dermatitis resembled second-degree burn injuries.
  • All patients had applied a poultice made from a plant.

Findings:

  • Plant specimens from all patients were identified as Ceratocephalus falcatus.
  • The dermatitis was attributed to the irritant properties of C. falcatus.

Implications:

  • This case series underscores the potential dermatological hazards of using C. falcatus in traditional remedies.
