We discuss below the benefits, properties, types and side effects of Green tea.

What is Green tea?

Green tea is prepared from the leaves of camellia sinensis, grown in China and Japan. The best quality of such tea is that the leaves undergo minimal oxidation during the processing and hence it is devoid of chemical substances and retains most of its healthy properties and ingredients.

Properties and Ingredients of Green tea

Green tea is loaded with anti-oxidant and anti-bacterial properties. The green tea leaves contain different enzymes, carbohydrates, dietary minerals, amino acids, bio-active compounds, lipids, sterols, related compounds, polyphenols, and flavanols which have their respective health benefits.

Health Benefits of Green Tea

Heart protection: The anti-oxidants in green tea help in reducing bad cholesterol, increasing good cholesterol, reducing blood pressure, and thereby help in protecting the heart. This was stated in a study made by Harvard Medical School’s Health Watch magazine.

Enhancement of Brain function: The caffeine content in green tea helps in improving brain functioning. Caffeine acts as a stimulant. The caffeine content in green tea is just sufficient enough to create a response without causing any side effects associated with too much caffeine. In various aspects of brain functioning, this property of green tea helps in improving mood, reaction time and memory. Along with caffeine, it also has the amino acid L-theanine, which is particularly efficient at improving brain function.
