Tri-ox compound

Tri-ox compound is an intravenous medicine which is designed to strenghten the cardiopulmonary system, and is effective in enriching a body of oxygen, and is essential to Humans and humanoids who find themselves in oxygen-poor environments, such as the planet Vulcan.

In 2267, Dr. Leonard H. McCoy feigned using tri-ox on Captain James T. Kirk, when Kirk engaged Spock during in the kal-if-fee ceremony on Vulcan. (TOS episode: "Amok Time").

In 2371, in the mirror universe, Jean-Luc Picard injected himself with a dose of tri-ox before entering the Sakethan burial mounds on New T'Karath. (TNG novel: Glass Empires: "The Worst of Both Worlds").
