The Claim
Dental calculus from an El Sidrón Neanderthal individual with a dental abscess and chronic gastrointestinal infection contained DNA from yarrow and chamomile, suggesting the presence of these plants in their oral microbiome during life.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
DNA from yarrow and chamomile plants was found in the dental calculus of a Neanderthal who had a tooth infection and gut infection, indicating these plants were present in their mouth, possibly due to consumption or use.
See the scientific wording
An El Sidrón Neanderthal individual with a dental abscess and chronic gastrointestinal infection (Enterocytozoon bieneusi) had DNA from the medicinal plant yarrow and the bitter-tasting plant chamomile in their dental calculus, suggesting possible self-medication behavior.
When someone eats plants with natural antimicrobial chemicals, those compounds enter the mouth and gut, where they kill or slow down harmful microbes causing infection. This reduces swelling and discomfort, helping the body cope with illness even without modern medicine.
What the research says
1 studyStudy: Neanderthal behaviour, diet, and disease inferred from ancient DNA in dental calculus
A Neanderthal who was sick had bits of yarrow and chamomile stuck in their teeth—plants that can help with pain and parasites. This suggests they might have eaten them to feel better.
