Spilanthes has a long medicinal history in India and South America. When bitten into, the leaves and curious button-like flowers have a temporary numbing effect in the mouth, earning it its nickname, Toothache Plant. But toothaches weren't the only ailment it was used to remedy, and today studies show it may have potential antifungal, antimicrobial, and anti-inflammatory properties, in addition to many others. It's also good for handing to unassuming friends and saying, "Here, try this!"
