Acmella oleracea is a species of flowering herb in the family Asteraceae. Common names include toothache plant, Szechuan buttons, paracress, jambu, buzz buttons, tingflowers and electric daisy. Its native distribution is unclear, but it is likely derived from a Brazilian Acmella species. A small, erect plant, it grows quickly and bears gold and red inflorescences. It is frost-sensitive but perennial in warmer climates.

Its specific epithet oleracea means "vegetable/herbal" in Latin and is a form of holeraceus (oleraceus).
