I’m going to start this monograph with a story about kiwi.
You’re probably wondering,
What does that have to do with Spilanthes?
Stick with me.
The first time I tried kiwi, I told my mom that it was like a party in my mouth. I felt every single taste bud waking up at once—sweet, tangy, and a little sour.
Spilanthes is the same kind of experience. Bite into a small yellow flower, and suddenly your mouth starts tingling and buzzing. Your gums go numb, your tongue feels alive, and you’re left wondering what in the world just happened.
But this “party in your mouth” has a purpose. Spilanthes’ distinctive tingle signals its healing action at work—an action that African communities have relied on for generations. This plant doesn’t need flashy packaging to prove its worth. It’s medicine that has stood the test of time.

From African Villages to Your Garden
In Cameroon, Spilanthes is crushed into a paste and applied to snakebites for pain and swelling. In South Africa, the Tshivenda people call it Tshishengelaphofu, traditionally using it for gum infections, toothaches, sore throats, and dysentery.
Today, most people know it as the Toothache Plant for its ability to numb oral pain instantly. In Brazil, it’s called Jambu, and it’s even cooked into traditional dishes for its unique tingling sensation.

From the Garden to the Apothecary
Spilanthes is simple to grow. Scatter its tiny seeds into rich soil, give them warmth and light, and within weeks you’ll see the plant’s bright yellow flower heads. By mid-season, you can snip flowers, leaves, and stems—the entire aerial part is medicinal.
Dry what you harvest to store for later, or use it fresh. Just handling the plant releases a bright, citrusy aroma. Taste a flower and you’ll immediately feel that characteristic buzz.
The Root of Healing
Spilanthes’ numbing and immune-stimulating power comes from spilanthol, a compound that interacts with nerve endings to dull pain while increasing circulation. It also works as a sialagogue, stimulating saliva production and supporting the body’s natural defenses.
It’s not just for the mouth. Spilanthes has proven antibacterial, antifungal, and antiparasitic actions. Modern studies confirm its ability to fight malaria, heal fungal conditions like athlete’s foot, and speed up wound healing.
