Introduction

While most people are aware of green tea's health benefits, few realize that excessive consumption can lead to unexpected side effects.

What is Green Tea?

Green tea is made from leaves harvested from the Camellia sinensis plant. After harvesting, the leaves are quickly heated—either by pan firing or steaming—and dried to prevent excessive oxidation, which would turn the green leaves brown and alter their fresh-picked flavour. Especially a brewed one is typically green, yellow, or light brown in color; furthermore, its flavor profile can range from grass-like and toasted (pan-fired) to vegetal, sweet, and seaweed-like (steamed). If brewed correctly, in general, most of them should be quite light in color and only mildly astringent.
