Spilanthol (affinin) 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.
The spilanthol proved effective at killing mosquitoes, with a 24-hour LD 100 of 12.5 μg/mL, and 50% mortality at 6.25 μg/mL. The mixture of spilanthol isomers produced a 66% weight reduction of corn earworm larvae at 250 μg/mL after 6 days. [18]
