Spilanthes - Acmella Oleracea Spilanthes is known as the “toothache plant” for its analgesic properties. When you eat a whole flower you experience a tingling numbing sensation, followed by excess saliva secretion and a clean, fresh taste in your mouth. It is quite an experience and makes you appreciate what a powerful medicinal plant it is. Spilanthes is mainly found in subtropical regions. It is traditionally used to help relieve dry mouth, gum irritation, as an appetite stimulant & palette cleanser and to reduce toothache pain. Spilanthes has many actions including anti fungal, insecticidal, antioxidant, aphrodisiac, antimicrobial, anti-inflammatory and local anesthetic. It is an immunomodulator, which means it increases the function of the immune response (similar to echinacea).
