Green tea is a type of tea made solely with the leaves of camellia sinensis that has undergone minimum oxidation during processing.
Green tea originated from China and has become associated with many cultures in Asia from Japan to Middle-East.
Only recently it has become widespread in the west where black tea is traditionally consumed.
Many varieties of green tea have been created in countries where it is grown. These varieties can differ substantially due to variable growth conditions, processing & harvesting time.
Over the last few decades extensive scientific and medical studies have been conducted on green tea which have revealed its substantial health effects with some evidences suggesting regular green tea drinkers may have lower chances of heart diseases and developing certain types of cancer
