What is the stimulating substance in Tea? Drinking Tea can invigorate you because it contains Caffeine. Caffeine is a xanthine alkaloid compound and a central nervous system stimulant that can temporarily drive away drowsiness and restore energy. Caffeine is extracted from tea leaves and coffee, effectively removing fatigue and stimulating the nerves.
What is the Stimulating Substance in Tea?
Caffeine can block adenosine in our brains. As long as adenosine cannot form an effective combination, we won't feel sleepy. This is precisely why after drinking coffee, which contains a lot of caffeine, we feel energized, but this can be harmful to the body. However, tea is different because it contains less caffeine, so the stimulating effect is milder, ensuring comfort while improving work performance and efficiency.
Next, we will discuss two other effective substances in tea: theobromine and theophylline. Theophylline is related to caffeine and belongs to a class of organic compounds called xanthines. These substances make breathing easier by acting on smooth muscles. In addition to improving breathing, they also stimulate the heart's contraction rate and strength. Theobromine also stimulates the heart and has diuretic effects, increasing blood flow and lowering blood pressure. However, excessive intake of these substances can be detrimental to health. In tea, these substances are present in small amounts. A Cup of tea can stimulate the body in various ways, achieving the desired effect without overstimulation.
The last key substance in tea we will introduce is L-Theanine. You may have heard of L-theanine; it is an amino acid. When combined with caffeine, it can improve brain function. This is why many people experience clarity of mind after drinking tea. This amino acid is quite unique and generally only found in tea plants. Now you understand how precious tea leaves are. Thanks to these substances, tea has not only captivated the world with its rich flavor for thousands of years but has also significantly enhanced work efficiency.
