I am looking to begin growing Acmella oleracea (Szechuan buttons). I would like to use them directly, and also make extracts specifically to maximize the taste/oral stimulation effect. Apparently there are a ton of different active chemicals.

So does anyone know what chemical(s) causes the licking a 9volt battery/buzzing teeth/foaming mouth sensations?


From the Wiki on Acmella oleracea, I get Spilanthol as the major compound in Jambu, an extract of the plant used culinarily for exactly the sensation you describe.
