Tricestium was considered an useless chemical by Romulans in the late 24th century. (RIS Bouteina) Brianna Reiss hatched a plan to recapture the HMS Sovereign that involved putting tricestium into the ice cream replicator recipes and have every child onboard the hijacked ship eat the tricestium-ridden ice cream so their temper, caused by the child-king syndrome would be more manageable. As such, tricestium had the same effect on Hydrans as would Ritalin on humans. (RIS Bouteina: "Spoiled Rotten")
