Vomit

Vomit was one of a variety of bodily fluids that could be squeezed out of the rocks of Nebulax 4. (TV: The Bounty Hunter) Vomiting was one of several conditions affecting young Killorans around their fourth year. (PROSE: Mentioning the War)

Humans could also eject vomit from their systems whenever they felt ill. As an added bonus to his infospike, in 200,000, Adam Mitchell had a Vomit-O-Matic implanted into him, which froze his vomit. (TV: The Long Game)

Izzy Sinclair vomited after she was brought inside the Keep via transmat. The Eighth Doctor implied that this often happened after a person's first journey on a transmat. (COMIC: The Keep)

Some people felt the experience of time travelling traumatic enough to vomit, as Mason Bennett did when the Twelfth Doctor took him in the TARDIS with his colleague Alice O'Donnell from 2119 to 1980. O'Donnell voiced to the Doctor her doubts that his past companions such as Rose Tyler, Martha Jones and Amy Pond, had "lost their breakfast on their first trip". (TV: Before the Flood)
