Introduction
With so many different plants existing in nature, why have people chosen to cultivate tea in particular?
This is because tea is not just a drink, but has been recognized since ancient times as a special drink that brings health to people.
People noticed that consuming tea leaves made their minds clearer and their bodies feel lighter, and became fascinated by its effects.
Before long, tea came to be valued as a cure-all and became deeply rooted in people's lives.
As time passed and technology advanced, it became clearer which specific components in tea, such as catechins and caffeine, are responsible for the health benefits mentioned above.
Tea is no longer simply a luxury item; it is also garnering attention as a functional food that helps maintain health.
It is hoped that in the future, the various health benefits of tea will be scientifically elucidated and used to help even more people live healthier lives.
