Acmella oleracea

Acmella oleracea is a species of flowering herb in the family Asteraceae. Common names include toothache plant, paracress, Sichuan buttons, buzz buttons,[2] tingflowers and electric daisy.[3] Its native distribution is unclear, but it is likely derived from a Brazilian Acmella species.[4] It is grown as an ornamental and attracts fireflies when in bloom.[citation needed] It is used as a medicinal remedy in various parts of the world. 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).[5][6]

For culinary purposes, small amounts of shredded fresh leaves are said to add a unique flavour to salads. Cooked leaves lose their strong flavour and may be used as leafy greens. Both fresh and cooked leaves are used in dishes such as stews in northern Brazil, especially in the state of Pará. They are combined with chilis and garlic to add flavor and vitamins to other foods.[7]
