Toxicity
All Narcissus species contain the alkaloid poison lycorine, mostly in the bulb but also in the leaves.
On 1 May 2009 a number of schoolchildren fell ill at Gorseland Primary School in Martlesham Heath, Suffolk, England, after a daffodil bulb was added to soup during a cookery class. The bulbs could often be confused with onions, thereby leading to incidents of accidental poisoning.
One of the most common dermatitis problems for florists, "daffodil itch" involves dryness, fissures, scaling, and erythema in the hands, often accompanied by subungual hyperkeratosis (thickening of the skin beneath the nails). It is blamed on exposure to calcium oxalate in the sap. It has long been recognised that some cultivars provoke dermatitis more readily than others. The cultivars 'Actaea', 'Camparelle', 'Gloriosa', 'Grande Monarque', 'Ornatus', 'Princeps' and 'Scilly White' are known to do so.
