Aldebaran mud leeches

Aldebaran mud leeches

An Aldebaran mud leech was a small annelid worm native to the mud of the Aldebaran star system.

They could be used to treat insomnia, as their secretions acted as a natural sedative. In order to do so, one had to place one leech on one's chest and one on the abdomen an hour before going to bed.

It was necessary to sleep on one's back while trying this treatment as rolling over might anger the creatures, according to Doctor Phlox, who kept some Aldebaran mud leeches in his sickbay aboard Enterprise NX-01. (ENT: "Anomaly")

In the final draft script of "Anomaly", the Aldebaran mud leeches in that episode were intended to be off-camera and produce "a strange alien trilling" noise. In the final version of the installment, however, they make no noise and appear on screen.
