Spilanthes is nicknamed the toothache plant. It temporarily numbs the areas of the mouth where it makes contact, mainly the gums, and through increased production of saliva has an antibacterial effect similar to that of echinacea. The increase of saliva is also useful in that strengthening and remineralization of tooth enamel relies on the availability of saliva.
Spilanthes is also antifungal and antiparasitic. It is considered an effective antimalarial herb, and has also been used to treat co-infections of Lyme disease. Spilanthes is native to Brazil and Africa where it is used to treat stammering and to improve digestion of carbohydrates and fats. Be aware that spilanthes causes a temporarily tingling sensation that is part of the immune response it triggers.
