Spilanthol is a fatty acid amide isolated from Acmella oleracea.[1] It is believed to be responsible for the local anesthetic properties of the plant.[2]

Spilanthol permeates the human skin [3] and the inside lining of the cheeks in the mouth (buccal mucosa),[4] resulting in local as well as systemic pharmacological concentrations.
