Herbology involves working with many useful and dangerous plants. Dragon hide gloves and wands are essential safety gear for Herbology classes. Plants like wolfsbane, peppermint, and valerian root are useful for making potions, while mandrakes and devil's snare pose health risks. Rat root has sedative and laxative properties and its smell makes it useful for floor coverings. Herbologists play an important role in potion-making and plant care, but the profession has lost respect over the past 300 years.
