Introduction


Green tea is one of the most popular and widely consumed teas in the world, known for its refreshing taste and numerous health benefits. But what is green tea made of, and where does green tea come from


If you’ve ever wondered about its origins, characteristics, and categories, this guide will provide a comprehensive green tea definition and explore its history, production process, and benefits.

What Is Green Tea? – Green Tea Definition

Green tea is a type of tea made from the leaves of the Camellia sinensis plant. Unlike black or oolong tea, green tea is minimally processed, which helps preserve its natural green color and high antioxidant content. This makes it one of the healthiest and most natural tea options available.


So, what is green tea made of? The primary ingredient in green tea is Camellia sinensis leaves, but it can also contain other natural elements such as jasmine flowers, mint, or dried fruits, depending on the variety.

Where Does Green Tea Come From?

Many people ask, where does green tea originate from, or where did green tea come from? The answer traces back thousands of years to China, where green tea was first cultivated and consumed. Historical records suggest that green tea has been enjoyed since the Tang Dynasty (618-907 AD), and it later spread to Japan, Korea, and eventually across the world.


So, where is green tea from today? While China remains the largest producer, green tea is now grown in Japan, India, Sri Lanka, Vietnam, and even some regions in Africa and South America. Each region produces green tea with unique characteristics due to differences in climate, altitude, and processing techniques.

What Plant Does Green Tea Come From?

One of the most common questions tea lovers ask is, what plant does green tea come from , or green tea is made from what plant?


Green tea comes from the Camellia sinensis plant, the same plant used to produce black, oolong, and white tea. The key difference lies in how the leaves are processed:

  • Green tea leaves are steamed or pan-fired immediately after harvesting to prevent oxidation.

  • This minimal processing preserves the green color, delicate flavor, and high antioxidant content.

Depending on the region, green tea can be made from Camellia sinensis sinensis (native to China) or Camellia sinensis assamica (native to India). The Chinese variety is typically lighter and more delicate, while the Indian variety has a bolder, more robust flavor.

Green Tea Categories: Types of Green Tea

There are various green tea categories, each with unique characteristics based on how the tea is grown and processed. The most common categories include:

Green Tea Herb: Is Green Tea an Herb?

While green tea is often called a green tea herb, it is not technically an herb. Herbs typically come from the leaves, flowers, or roots of non-woody plants, while green tea is derived from the Camellia sinensis plant, which is a shrub.


However, green tea is frequently blended with herbs like mint, chamomile, and lemongrass, making it a popular herbal infusion.
