The Stewie Analysis and The Ultimate Ointment

Dr Keto nodded as he spoke into the telephone, at the same time as
looking at several medical reports (now viciously highlighted in red
pen).
"Yes, Mr McKenzie, I have confirmed that you have the infection as
well," he nodded. He listened to the reply.
"How are you?" he mused, "Well, if it's any consolation, you're not
the worst affected..."
He glanced over in the corner of the medical laboratory. Several
crewmembers (redshirts :)) were now in straightjackets, gibbering
incoherently. One of them was yelling, "The grapefruit! The
GRAPEFRUIT!" over and over. Keto shook his head.
"No, Mr McKenzie, I'm afraid there is nothing I can do for you at
this stage, priority goes to the worst affected patients. As soon as
you begin to have hallucinatory visions of your own death, come and
see me."
With that, without waiting for the "But I have" reply, he hung up
and sighed heavily.
The infection, virus, whatever it was, was spreading rapidly
throughout the ship, and he was still little or no closer to finding
a cure. Initial checks had eliminated any possibility of it being a
purely bacterial illness. Several crewmembers were now suffering
from "PJT Syndrome Disorder" - Pink Jumping Tree sightings - and a
few claimed that a man in a thick robe with terrible curry breath had
been following them around.
Keto himself had seen several man-sized flasks of ointment sprout
legs and try to spill themselves on him. However, he had been
fortunate.
He had been carrying a demister bottle filled with...
The Ointment.
Keto had been preparing it for months, ever since he came to this
ship. That demister was his last supply from the last batch. The
new batch should be ready in a few days, it just needed to simmer a
little more.
And required the special ingredient, of course. Finding some of it
out here would be difficult, but he had to hope. The Ointment could
be the Blue Dwarf's only hope.
Cries of "GRAPEFRUIT!!!" roused him from his thoughts. Sighing,
Keto stood up and got back to work.
It was going to be a long day...
====================
What effect does the Ointment have on the hallucinations?
What is the secret ingredient?
Will grapefruits try to take over the ship?
Will Stewie risk visiting Keto's office?
