To attain health benefits of tea, the quality of your tea leaves is very important. The higher the quality of tea leaves you are infusing to drink, the stronger the health benefits you'll be reaping. Old and inferior leaves have lost most of their nutritional and health boosting value, similarly as old and dried up fruit and vegetables. So keep that in mind when drinking tea for health reasons (your taste buds will be grateful to you as well since fresh, high quality tea tastes so much better).
All types of tea are beneficial for our health, each in their own way due to their differing chemical profiles. Antioxidants in green tea have been most widely researched however, so unless otherwise specified, we focus here mainly on the benefits of green tea.
Green tea has been drunk around the world for many centuries, and in East Asian countries has also been used as a traditional medicine. Some of its traditional uses are: stimulant (due to caffeine and essential oils content), diuretic (removing excess water from the body), astringent ('tightening' effect, controls bleeding and helps heal wounds) and improving heart health. It is also valued for regulating body temperature (in both hot and cold weather), regulating blood sugar and cholesterol levels, promoting digestion and improving mental processes.
Below you can find the list of most researched benefits attributed to tea, ranging from its beautifying properties, protective and preventative qualities in terms of serious disease, to promoting mental clarity.
