Kolaish spice oil

From Memory Alpha, the free Star Trek reference

Kolaish spice oil (pronounced like collage with -sh instead of -zh) was a type of oil-lubricant available on Bajor.

Shakaar Edon used some to massage Kira Nerys at his home the night he persuaded her to attend a Cardassian conference to share Bajoran intelligence on the Klingons. (DS9: "Return to Grace")
