Doctor Ixta was a 23rd century Zargotian man. He was a leading physician on the planet Zargot in the Alpha Helios star system.
History
In the 2260s, the Zargotians began to contract a deadly plague they referred to as a creeping sickness. As more and more people became hospitalized and monitored in biobeds, Ixta became convinced that an antidote could be developed from herbs grown on neighboring planet Coltac. He met with Doctor Leonard McCoy and Captain James T. Kirk of the USS Enterprise. As Zargotians were no longer healthy enough to travel, Kirk retrieved the Coltac herbs for him. McCoy and Ixta rapidly developed an antidote, and within a short time, the population was cured. (TOS comic: "Target: Zargot")
