A female Klingon brought a bottle of syrup of squill to Morn's wake later that year. (DS9: "Who Mourns for Morn?") The phrases "syrup of squill" and "hypicate root futures" are taken from the 1934 Norman Z. McLeod movie It's a Gift, starring comedian W.C. Fields. (Star Trek: Deep Space Nine Companion, p. 518) In the real world, "squill liquid extract" (an alcoholic preparation derived from a flowering plant native to Europe, Asia, and Africa) is an ingredient used in cough medicines.
