Smelling salts - secrets you never knew
Smelling salts were first recorded in ancient Rome. In the 13th century, alchemists used smelling salts. In the 17th century, people extracted smelling salts from deer antler shavings, so it was also called "deer antler wine"

If you like sports, then you probably know that smelling salts are widely loved by athletes, whether it is ice hockey, rugby, baseball, football and other ball sports, or boxing, free fighting confrontational sports, in heavy sports, weightlifting and powerlifting, you will often see smelling salts

Smelling salts are a solution of ammonium carbonate - molecular formula (NH4) 2CO3-H2O In ancient times, smelling salts were widely used, but not for athletes. Instead, they were used to treat many diseases you would never imagine, such as insomnia, abdominal discomfort, sexual frigidity, and sexual hyperactivity (sounds interesting, right?)

Ancient Egypt believed that many female problems such as insomnia, abdominal discomfort, sexual frigidity, and sexual hyperactivity were related to the position of the uterus, and some mental illnesses such as hysteria were also related to the position of the uterus

And the treatment of the disease only requires returning the uterus to its normal position (what kind of logic is this) So how can a woman's uterus return to its normal position? The answer is: using smell (1)
Ancient Egypt published a book of pharmaceutical knowledge in about 1554 BC - the Ebersbebe Book. papyrus) records a lot of treatments for diseases, and the diseases of women in this book are about ectopic uterus. For example, if the uterus is too high in the abdominal cavity, then put some sweet smelling things to attract the uterus down.
For patients with a low uterus, use smelly things to push the uterus upward, and the smelly things are ammonium carbonate solution, that is, smelling salts for treatment
In addition to being used as so-called "treatment", smelling salts are more used for awakening. In the Victorian era in Britain, smelling salts were a must-have for ladies in the upper class. In order to appear delicate, ladies would faint when encountering things, so it was widely used to awaken fainted women

During World War II, smelling salts were widely used. The British Red Cross used it as the first item in the first aid kit. Using smelling salts to awaken is a serious matter, but in modern times, many medical professionals still oppose it. Smelling salts are used to wake up people who are unconscious due to sports trauma, because the respiratory twitching caused by the irritation of ammonia may aggravate the trauma, and the ammonia produced by smelling salts is toxic to a certain extent, and large amounts of inhalation may even be fatal.
Among athletes, smelling salts can be described as rampant. No matter what sport it is, you can see smelling salts, and the more confrontational the sport, the more you can see smelling salts.

However, there is no high-end scientific research evidence to support smelling salts. If you have tried smelling salts, you will know that this thing is to concentrate the smell of the toilet 100 times into a small jar. Imagine - a pungent smell rushing straight to the head.
There is no convincing enough scientific research evidence to support that smelling salts can improve sports performance or increase excitement, but smelling salts rely on their unique smell, which makes many sports love and hate them. The smell is unique! The smell is choking, and you will become abnormally sober immediately after smelling it!
