Toothache Plant, Botox Plant. 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. 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. 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. Can be grown in a container and as a houseplant.
