Viral TikTok videos promoting garlic fermented in honey as a natural antibiotic have prompted public-health warnings. Experts say fermenting fresh garlic in unpasteurized honey at room temperature can create conditions that allow Clostridium botulinum to grow and produce dangerous toxin. Botulism is rare but can be deadly—infants are especially at risk. Officials advise consulting a health professional and avoiding homemade antimicrobial substitutes; do not give raw honey to infants under one year.
Viral TikTok Trend — Garlic Fermented in Honey — Could Cause Botulism, Experts Warn
Honey and garlic in a jar.
As flu season approaches, a viral TikTok trend promoting garlic fermented in honey as an "all-natural" antibiotic and detox tonic has drawn warnings from public-health and food-safety experts. While garlic and honey each have some antimicrobial or antioxidant properties, combining them in the ways shown online can create conditions that allow Clostridium botulinum spores to germinate and produce dangerous toxin.
Why this mixture can be risky
Clostridium botulinum flourishes in low-oxygen environments and needs particular moisture and pH conditions to produce toxin. Under normal circumstances, the low water activity of honey makes bacterial growth unlikely, and garlic on its own is not a common growth medium. But when fresh garlic is submerged in unpasteurized (raw) honey at room temperature, microbes can draw moisture from the garlic and raise local water activity. If fermentation does not acidify the mixture quickly enough, those pockets can support spore activation and bacterial toxin production.
"Fermenting garlic in unpasteurized honey at room temperature can pose a risk of botulism," says Karine LeBlanc, a spokesperson for Health Canada. "Storing the mixture at room temperature may further increase the risk."
Symptoms and severity
Botulism is caused by a nerve-targeting toxin that can produce muscle weakness, slurred speech, drooping eyelids, difficulty breathing, abdominal pain, nausea, vomiting and diarrhea. If not treated promptly in a hospital, botulism can be fatal because respiratory muscles (including the diaphragm) can become paralyzed.
"If you consume that toxin, then it will exhibit its paralytic effects on you," says Joy Gail Waite-Cusic, a food-safety professor at Oregon State University. "Among the most common targets is your diaphragm, and so you stop breathing."
How common is botulism?
Botulism is rare. According to the Centers for Disease Control and Prevention (CDC), the United States recorded 243 confirmed cases and 30 probable cases in 2021, with 181 of those cases occurring in infants—the highest infant incidence since national reporting began in 1976. Infants are especially vulnerable because their gut microbiome is not yet mature enough to resist intestinal colonization by C. botulinum.
Although adult intestinal colonization is uncommon, it has been documented in a small number of cases (some linked to contaminated peanut butter and other foods). When recognized early and treated in hospital settings, botulism is treatable, but delays can be life-threatening.
Practical advice
Health officials urge people not to substitute homemade remedies for medical treatment. "If you think you may need an antibiotic or other antimicrobial medication, speak with a health care professional," LeBlanc says. "Antimicrobial medications, including antibiotics and antivirals, should only be used when prescribed."
Food-safety experts suggest that people who want the benefits of garlic and honey may be safer eating them raw and separately rather than fermenting garlic submerged in honey. Crucially, raw honey should never be given to infants under one year of age because of the risk of botulism.
"You actually have the best antioxidant potential if they're both raw," Waite-Cusic adds. "So you just want to eat the clove of garlic that's now sweeter."
