Rama leaf
From Memory Alpha, the free Star Trek reference
Rama leaf is a part of a plant from the Delta Quadrant, used as an herb.
A Talaxian theta radiation remedy calls for crushed Rama leaf and Katyllian cloves, though the mixture also triggers a gag reflex. Neelix made some in 2375 while preparing to board a disabled Malon freighter. (VOY: "Juggernaut")
