These sealed yellow-paper-wrapped aromatic spirit of ammonia ampoules were manufactured by Mine Safety Appliances Co., a company better known for gas masks, respirators, and industrial safety gear. Each ampoule contains 2 cc of a 66% alcohol-based ammonia solution, intended for emergency treatment of shock, collapse, or fainting.

The label outlines two methods of use:

• Inhalant: Break the tip, soak cotton, and inhale the vapors.

• Oral stimulant: Shake into half a glass of water and drink.

Often used in both medical and industrial first aid kits, these ampoules were marketed for rapid arousal and revival in settings like construction sites, coal mines, and battlefield medicine.

Aromatic ammonia solutions have long been a go-to “revival agent” in both professional and civilian settings. Popular from the 19th century through mid-20th century, these preparations—often referred to as smelling salts—were believed to stimulate the sympathetic nervous system by irritating the mucous membranes and triggering a rapid inhalation reflex.

While most modern use is restricted to athletic sideline revival or historical re-enactment, these ampoules were once standard equipment in crash carts and trauma kits. The packaging, dosage style, and dual-use design speak to an era when field expediency outweighed nuance, and revival was prioritized over comfort or long-term safety.
