Urtication
Definition:
(n.) The act or process of whipping or stinging with nettles; -- sometimes used in the treatment of paralysis.
Example Sentences:
(1) Caripito itch, a pruritic dermatosis rarely seen in the United States, is caused by contact with moths of the genus Hylesia--specifically, with urticating abdominal hairs of the adult female moth.
(2) There was a strong correlation between the susceptibility of each subject to each urticant, but no correlation between the susceptibility to NIICR and age, atopic status or tanning ability.
