Thanks to special equipment that managed to carry out chemical analysis of Neanderthal remains, scientists found out that these creatures did not only feed on meat, but also plant food, and some herbs they used not only to quench hunger, but also to treat them.$ Moreover, it was possible to establish that products of plant origin were often cooked on fire, and not eaten raw. Among other things, molecules of bitter medicinal plants were found in the plaque on the teeth of Neanderthals, among which scientists believe were yarrow and chamomile. At the moment it is well known that such plants have special healing properties, but it turned out that this was known by proto-humans who lived on Earth many millennia ago. There are at least three reasons for claiming that yarrow, chamomile and some other bitter plant taste were used precisely for treatment. First, according to many studies, taste buds in Neanderthals were well developed, and they would not eat bitter herbs for a reason. Second, chamomile and yarrow have very low nutritional value in contrast to meat and other plant and animal products that proto-humans fed on. Thirdly, according to the analysis, one of several Neanderthals who lived in the cave ate bitter medicinal plants very often, while other creatures whose remains were found there , consumed them occasionally, while food was shared between everyone roughly equally. Unfortunately, scientists have not yet been able to understand whether Neanderthals have used herbs themselves or prepared mixtures, decoctions, etc. Also, it is difficult to establish which plants other than yarrow and daisies were used by proto-humans for treatment and which specific ailments they intended to be rid of by such means.
