Acmella oleracea

Acmella oleracea, also known under its old names Spilanthes oleracea and Spilanthes acmella and commonly referred to as Spilanthes Extract, is a flowering herb in the plant family Asteraceae, also known as toothache plant or paracress as the leaves and flower heads contain an analgesic agent spilanthol used to numb toothache. It is native to the tropics of Brazil, and is grown as an ornamental (and occasionally as a medicinal) in various parts of the world. A small, erect plant, it grows quickly and sends up gold and red flower inflorescences. It is frost-sensitive but perennial in warmer climates.
Medical uses and effects
A decoction or infusion of the leaves and flowers is a traditional remedy for stammering, toothache, stomatitis,[1] and throat complaints.[citation needed]


Acmella oleracea extract has been tested against various yeasts and bacteria and was essentially inactive.[3]

Acmella oleracea has been shown to have a strong diuretic action in rats.[4]

Spilanthes extract has been discovered to aid in saliva stimulation for people suffering from dry mouth (xerostomia). Its properties provide relief to dry mouth by enhancing saliva production.[citation needed]

Acmella oleracea extract is reported to reduce muscle tension when applied topically, and as such it aids to decrease facial lines and wrinkles that are partially caused by tense or contracted facial muscles. Application of Acmella extract is reported to result in more relaxed facial muscle, and in turn in a decrease of visible wrinkles, ageing lines, "crows feet", etc. Some people[who?] compare it to Botox, but without the toxic effects and without the need to inject it under the skin; a cheap and easy to apply herbal Botox replacement.
