Spilanthes (Acmella oleracea), commonly called the Toothache Plant, is one of the most immediately experiential plants in the medicinal herb garden - bite into a fresh flower head and within seconds a powerful, buzzing, tingling sensation spreads across your tongue and cheeks, followed by a wave of saliva and a mild numbing effect. It is an unmistakable botanical experience. The flowers themselves are distinctive: cone-shaped golden-yellow heads with a dark reddish-brown central disc, produced prolifically on a spreading, mounding tropical annual.

Growing Information
Spilanthes thrives in full sun to partial shade and moist, well-drained, fertile soil. It is a tender annual from the tropics and needs warm conditions to perform well - do not transplant until nighttime temperatures are reliably above 55 degrees F. Plants form a spreading mound 12-18 inches tall and wide, covered in flowers from midsummer until frost. Keep consistently moist; Spilanthes does not tolerate drought well. An excellent container plant that can be moved indoors in fall.

Traditional Use
Spilanthes has been used in traditional medicine across South America, Africa, and Asia for centuries, valued in the folk traditions of every region where it grows natively. The flowers and leaves are the parts most used by herbalists, with the fresh flower heads most prized for their powerful active compounds. In Brazilian folk medicine it has been used as a dental herb for generations - the common name Toothache Plant reflects this traditional application. Contemporary herbalists value it highly as an immunomodulating and salivary-stimulating herb.

Care on Arrival
Water upon arrival and keep in a warm, sunny location. Spilanthes is heat-loving and cold-sensitive. Transplant after your last frost date into moist, enriched soil in a warm, sunny location. Keep consistently moist throughout the season - mulch helps retain soil moisture. Harvest individual flower heads as they reach full development for the most potent aromatic effect. The plant produces flowers continuously from midsummer until frost, providing an ongoing harvest.
