Penicillin is historically a new discovery, but recent research shows that humans have used antibiotics for over 2000 years – combined with beer.
In mummies from regions in present Egypt, scientists have found large quantities of the antibiotic tetracycline, which was patented as late as in 1950.
The people who lived 2,000 years ago knew the power and utilized it consciously. So even if they had no knowledge of germs and infections, so they knew about the effect.
How did antibiotics end up in beer?
The barley beer was brewed on was infected with a mold-like bacteria. The grains had usually been in contact with the bacteria in the soil.
The bacterium produced tetracycline to kill other bacteria that could compete. Therefore, it served as antibiotics.
Back then, people drank beer for many ailments right from the age of 2 years.
So, even that antibiotics have been used by people in over 2000 years, it first became famous in 1928 when scientist Alexander Flemming discovered the penicillin and its effects on diseases.
