From HausMagick: "Mystics in the medieval ages used amethyst to treat everything from spider bites to acne. This purple sparkler is widely known and easily available in many forms. Known for emotional and spiritual protection, amethyst can break anxious or addictive thought patterns and help you move into a higher consciousness. Its high vibration blocks negative, stressful energies and stimulates serenity of the mind. Placing an amethyst on your nightstand will protect you from nightmares."
