Researchers were able to collect plaque from the teeth of four Neanderthals from two sites — one in Spy, Belgium, and the other in El Sidrón, Spain. In his plaque, researchers found traces of poplar, which contains salicylic acid, a form of which is the active ingredient found in Aspirin. Neanderthal teeth found in Belgium, showing plaque on the tooth enamel. The researchers also found a link between Neanderthals, ancient and modern humans and the microbes they possessed, including bacteria that causes gum disease and cavities. Using this new branch of science, the researchers were able to paint a picture of what our ancient relatives consumed.
