Daffodils cause irritant contact dermatitis in florists due to calcium oxalate crystals in their sap. Wearing protective gloves and clothing is the best way to prevent daffodil rash.
Area of Science:
- Dermatology
- Botany
- Toxicology
Background:
- Daffodils (Narcissus species) are frequently implicated in occupational skin conditions.
- Florists are particularly at risk for developing contact dermatitis from handling daffodils.
Purpose of the Study:
- To identify the cause of irritant contact dermatitis in florists.
- To describe the clinical presentation of daffodil-induced dermatitis.
- To recommend preventative measures.
Main Methods:
- Clinical observation of affected individuals.
- Identification of causative agents within daffodil plants.
Main Results:
- Calcium oxalate crystals in daffodil sap are the primary cause of irritant contact dermatitis.
- Daffodil rash typically manifests as fissuring, scaling, and erythema on the hands and forearms.
Conclusions:
- Daffodil sap contains calcium oxalate crystals that induce irritant contact dermatitis.
- Protective measures, including gloves and clothing, are essential for prevention.
