Antacid
From Memory Alpha, the free Star Trek reference
An antacid is a form of medication that helps alleviate acute functional dyspepsia (heartburn).
When Neelix made up Rodeo Red's Red-Hot, Rootin'-Tootin' Chili, several crewmembers received heartburn, thus requiring Tom Paris to replicate an antacid for them. (VOY: "Message in a Bottle")
