Jestral tea was a type of Betazoid tea which was favored by Lwaxana Troi. Troi found the beverage to be comforting in times of anxiety and stress and ordered frequently while aboard the USS Enterprise-D in the run-up to her intended marriage to Campio in 2368. However, when she first came to order the beverage from the ship's replicator's she found that it wasn't on file, and she was presented with a plate of hearty Petrokian sausage instead.
