Adrenaline is a hormone secreted by the body. When people experience certain stimuli, such as excitement, fear, and stress, they release adrenaline, which causes the heart to beat faster, blood flow faster, and breathing faster. This can give the body more energy and make people respond more quickly. We call this ‘Fight or Flight Response’. Extracts of the adrenal gland were first obtained by Polish physiologist Napoleon Cybulski in 1895. In 1901, Takamine successfully isolated and purified the adrenaline. Nowadays, people more and more use adrenaline as medicine to treat many kinds of diseases especially Rescue cardiac arrest and anaphylactic shock.
