The Man Trap: (Episode 6)
When the U.S.S. Enterprise's landing party arrives on a planet to give a routine medical examination to Nancy and Robert Crater, a nightmare unfolds when several members die, every trace of salt mysteriously removed from their bodies. Since McCoy was once deeply in love with Nancy, he's especially concerned for her safety. However, the real Nancy Crater is already dead; a being has taken her form and needs salt to survive. Because Carter's supply is gone it has only one source - the crew of the U.S.S. Enterprise.
