Bottled green tea sold in the market now belongs to green tea beverage. Please note that it is a drink. These green teas are not all brewed with tea leaves bit by bit as we imagined, but something similar to green tea starter is added in the production process. This green tea starter is a deep-processed product with many spices added. And in the production process, various flavors are added to the products. These essences are all chemical products. None of them are natural. Therefore, instead of drinking green tea, it is better to drink water made of essence and saccharin. It is better to drink boiled water at home. Although these edible flavors will not have a great impact on the human body, chemical products will not be beneficial to health. So it is better to drink less bottled green tea.
