Penicillin is an antibiotic compound produced by the Penicillium mould, but in recent times synthetic penicillin has become available, attacking a wider array of bacteria. It was first mass produced in The United States of America during World War II and used with resounding success to treat Allied troops, drastically reducing casualty rates from infected wounds. After the war, it was commercialised and became one of the most important pharmaceutics of the modern world. It is locally produced in Oceanyka, but prices remain high due to the country's enormous population and proclivity to suffering from open wounds (typically gunshots). The most common variants are Penicillin G (taken by injection) and Penicillin V (taken orally).
