What does urtication mean?
Urtication is a specialized medical term for an itchy, raised eruption of the skin, especially the wheal-like rash commonly called hives or nettle rash. In some contexts, it also refers to the process of developing such an eruption. The reaction may occur because of an allergy, a physical trigger, or contact with an irritant, depending on the clinical situation. Urtication is consequently more common in medical discussions of allergies, dermatology, and case reports than in everyday conversation. Writers who need the name of the established condition will often use urticaria, while urtication can describe the visible eruption or its onset. Although uncommon, the word is useful because it identifies a distinctive skin response without relying on the less precise general term rash. Its Latin ancestry is equally memorable: the term derives from the Latin word for nettle, reflecting the historical description of the rash as resembling nettle stings.

Urtication comes from the Latin word for “nettle”—the same root behind urticaria and the raised welts of hives.

Etymology of urtication
Urtication entered English in the 17th century from Latin urticatio, meaning “an itching.” This developed from Latin urticare, “to itch,” which in turn comes from urtica, “nettle.” The same Latin root underlies urticaria and urticant, while nettle is a related cognate in English.

Easily confused with urtication
