Herbal medicine in Asia has used green tea for conditions such as promoting digestion, improving mental focus and regulating body temperature and blood sugar. A study on green tea and cardiovascular and liver disease by Dr. Imai and Dr. Nakachi concluded, "The inverse association between consumption of green tea and various serum markers shows that green tea may act protectively against cardiovascular disease and disorders of the liver."
Some of the causes of eye puffiness and dark circles can be avoided or reduced. Alcohol and tobacco use lead to fluid retention around the eyes, causing swelling.

Eye swelling is a temporary condition. Chronic eye puffiness may be a sign of other serious medical conditions. A skin patch test should be done before using tea bags on the eyes, especially for individuals with allergies.
