Sometime between 575 and 850 CE, nomadic mountain warriors of the Galla tribe in Ethiopia would combine crushed coffee beans with animal fat, and snack on that for energy during long treks and warfare.
In the new study, scientists found that several containers with the word " antiu" contained a mixture of different substances — including animal fat, cedar oil and juniper resin.
They found pine resin which has anti bacterial properties, animal fats and possibly olive oil, known for its use in ancient perfumes and medicinal preparations.
