Purple lotus

The purple lotus is a lotus flower with purple blossoms that grows in the ghost-haunted swamps of southern Stygia. The juice of the purple lotus causes temporary paralysis. The body is rendered immobile but the victim's mind remains active. The wizard Tsotha-lanti wore a ring that had a retractable metal fang steeped in purple lotus juice. He was able to take King Conan prisoner by striking him on the arm and paralyzing him.
