Jitsu also known as Aernaeth, Eärenahta and Razorback was a yellow concentrated venom obtained from the Jitsu, a large clam native to temperate shallow seas, closely related to the jitsukar and jitsutyr, despised as a dangerous pest by fishermen.

Some of the oil floated to the surface, where it was collected and heated until its color darkened from pale straw to bright canary yellow.An Antidote against Jitsu poisoning was the Shadowvine
