Passiflora incarnata Linneaus as an anxiolytic before spinal anesthesia.

Purpose: Patients who undergo regional anesthesia experience anxiety in the preoperative period. Passiflora incarnata Linneaus is a plant that has traditionally been used as an anxiolytic and sedative. We aimed to investigate the effect of preoperative oral administration of Passiflora incarnata Linneaus on anxiety, psychomotor functions, sedation, and hemodynamics in patients undergoing spinal anesthesia.
