Answer

The family Alstroemeriaceae includes the Peruvian lily. Florists often develop erythema, fissures, vesicles, hyperkeratosis, and exfoliation of the fingertips, which often affects their dominant hand. The allergen can pass through vinyl (eg, polyvinyl chloride) gloves. [12, 13]

Tuliposide A and B are found in virtually all portions of the plant. The flowers, shown below, contain more allergen than the stems; the leaves have the smallest amount of allergen.
