Acisanthera sp.

Acmella oleracea, Spilanthes oleracea

Toothache Plant is a medicinal herb that has been used for generations to manage the pain of toothaches. Both the leaves and the attractive golden flowers can be used as a natural anesthetic. Simply chew the leaves or flowers for a few seconds then you will experience a tingling and numbing sensation in your mouth. An infusion or tincture made from the Toothache Plant is said to promote gum and throat health due to its strong antibacterial properties. For culinary purposes, small amounts of shredded fresh leaves are said to add a unique flavor to salads. Cooked leaves lose their strong flavor and may be used as leafy greens. Both fresh and cooked leaves are used in dishes such as stews in northern Brazil. They are combined with chilis and garlic to add flavor and vitamins to other foods. The use of jambu extract as a food flavor is described as having an odor of citrus, herbal, tropical or musty odor, and its taste can be pungent, cooling, tingling, numbing, or effervescent.

Acmella Oleracea extract is considered a natural alternative to Botox. Applied topically, Acmella Oleracea reportedly reduces muscle tension, reducing facial wrinkles caused by tense or contracted facial muscles. It is considered a natural muscle relaxant and has been traditionally used as an herbal Orajel of sorts, thanks to the presence of analgesic alkylamides called spilanthol. This spilanthol is thought to have the same paralyzing effects on facial muscles as it does on gums, reducing wrinkles by relaxing the skin. It's seen in topical formulas and can easily penetrate the skin, inhibiting contractions in subcutaneous muscles.

The plant is a small, erect, it grows quickly and bears gold and red inflorescences. It is frost-sensitive but perennial in warmer climates. Can be grown in a container and as a houseplant.
