A local folk remedy in Boho, Ireland was to place soil from the local church under a pillow while you slept to cure infections. In 2018 a microbiologist found the churchyard’s soil contains a previously unknown strain of streptomyces which can be used to create antibiotics.
Alexander Fleming discovered penicillin, but never tried to make an antibiotic out of it. It was not until a decade later that a man named Howard Florey found Fleming’s little-known paper and realized the mold’s potential. Florey’s work is estimated to have saved up to 200,000,000 lives.
