Wake the Dead smelling salts is a POTENT smelling salt (enhanced with Spearmint or Wintergreen), developed by the Mad Chemist to help you get your best lift. Our smelling salts, when hydrated in accordance with the label, release ammonia gas - triggering a strong inhalation reflex. This reflex causes the muscles that control breathing to work faster, while also activating the sympathetic nervous system - increasing the heart rate, blood pressure, and brain activity.
