We often get asked, does green tea have caffeine and how healthy is it really? In this post I will share the history of green tea, the health benefits and the bottom line of exactly how much caffeine does green tea really contain.
Where did green tea originate?
Sometimes people ask, Is green tea Japanese or Chinese?
Green tea, as research implies, originated from China.
The roots of green tea began way back in Ancient China, going back as far as 2737 B.C. The finding occurred by accident when the Chinese Emperor Shennong mistakenly drank water that had a dead tea leaf boiled in it.
The emperor then found the flavour refreshing, and thus, a new beverage, green tea, was officially born. Green tea was primarily available to the highest tiers of Chinese society and was very expensive to purchase. It was not until the 14th century that green tea became accessible to the general public for enjoyment and medicinal purposes.
Around 800 A.D., during the Tang Dynasty, an innovative book titled "Cha Jing," also known as "The Classic of Tea," was written by a Chinese man named Lu Yu. When he was a young boy, Lu Yu was adopted by a Buddhist monk and grew up brewing and serving tea. As he grew older, his interest in tea blossomed, and his abilities to make tea improved. He decided to take time away from the outside world to research and write down his findings. "The Classic of Tea" became the first written work to explain green tea culture and art.
Green tea is primarily from China's Yunnan province and is widely considered to be the original home of the Camellia sinensis plant species.
Does Green Tea Have Caffeine?
Considering that The general consensus among the tea community is that a teacup in measurement terms is 6.0 ounces. A six-ounce cup of green tea usually contains somewhere between 35 and 45 mg of caffeine, which is a low dose of caffeine and according to the Mayo Clinic, the recommended dose is 400mg per day for healthy adults.
Also, its important to bear in mind that not all green tea is the same—there are multiple varieties, including matcha, sencha, and bancha.
The exact numeric amount of caffeine in green tea will depend 100% on the type of tea, the quantity of water used and how it’s brewed.
Why is Green Tea Healthy?
