Somata oil was a type of massage oil favored by Intendant Kira Nerys.

While visiting the prime universe, she convinced one of Deep Space 9's Bajoran security guards to give her a massage to ease the pulled muscles in her shoulders. During the uncomfortable massage, she suggested "if only we had some warm Somata oil... that would be nice, don't you think?" He replied, "I guess...", a split-second before she took the opportunity to knock him unconscious. (DS9: "Resurrection")
