Neanderthals likely used birch tar glue as ancient antibiotic
Researchers from the University of Cologne and other institutions found that Neanderthals may have used birch tar to treat wounds and fight infections in October 2026.
Study recreates ancient production methods
Scientists recreated techniques believed to be used by Neanderthals to produce birch tar. The team tested every sample for its ability to stop bacterial growth. Results showed the substance could inhibit bacteria responsible for dangerous wound infections.
Birch tar served dual purpose
The material was previously known mainly as a prehistoric adhesive for tools. Researchers suggest it doubled as effective natural medicine for protecting wounds. This finding comes from a study published in PLOS One.
