Spilanthes acmella (toothache plant)
What it is
Known as the toothache plant or buzz buttons, Spilanthes contains spilanthol which produces a characteristic tingling and numbing sensation. Traditional use across Africa, South America, and Asia for dental pain and oral infections. Confirmed local anaesthetic and antimicrobial activity in lab studies. Almost no clinical trials in humans. Novel food ingredient gaining popularity in cocktails and cuisine.
Dose
No standardised oral dose. Traditional use: chew 1 fresh flower head or apply 5–10 drops of tincture topically to gums for short-term tooth-pain relief. Limited modern clinical data.
Time of day & tips
Chewing a fresh flower head produces an intense tingling and numbing sensation — this is normal. Topical application to gums for toothache is the traditional use. Not a substitute for dental care.
