The Acid Iron Earths were a minor league baseball team based in Mobile, Alabama. In 1886, the uniquely named "Acid Iron Earths" played as members of the independent Gulf League, winning the league championship in the league's only season of play. The team played home games at Frascati Park, which contained the first professional baseball park in Mobile. The "Acid Iron Earths" team name corresponds to the eras locally produced "Acid Iron Earth" medicinal tonic. The team was owned by Charles Mohr, who had a patent on iron tablets, who's local company manufactured the Acid Iron Earth tonic. The Acid Iron Earths are believed to be the first professional team to travel to a foreign country, playing exhibition games in Cuba.
