Worldwide, the flower heads are used either fresh or dried and powdered, but the use of roots and leaves have been recommended as well.

It is used against blood parasites, especially against malaria, both prophylactic and curative.

These plants have an interesting chemistry, containing flavonoids, sterols, sesquiterpene lactones and amides, notably spilanthol, which has anaesthetic effects. The flowers are the most numbing part of the plant. Spilanthol is also a potent insecticide, able to kill mosquito larvae at a concentration of 1/100,000.

The tingling sensation has also caused rumours to spread regarding spilanthes’ application in oral sex. The taste buds, gums, and entire mouth become overwhelmed by the intense tingling buzz, saliva swirling stimulating sensation. The mouth is being cleaned and the gum tissues, lymphatic and immune systems stimulated and strengthened.
