Jilnak is a substance vomited up by Utu-Noranti Pralatong. It is unknown whether her ability to regurgitate jilnak is unique to her or is a common trait amongst Traskans – however, it is certain that jilnak is a nutritious restorative, as Noranti claims it to be, only by virtue of the fact that it is a powerful emetic that forces the unlucky ingestor to vomit horrifically and repeatedly. According to John Crichton, it tastes like chicken. ("Lava's a Many Splendored Thing")
