Tea leaves in their natural green form have been ingested in one form or another for the past 4000 years and the longevity of their usage popularity has proven itself to be a very valuable source of health and wellbeing. During the early human history, before supermarkets and chemists, people made discoveries about food through trial and error. Tasting the unknown flora and dividing each discovery into a food, a medicine or a poison. The knowledge of each of these discoveries would then be shared and passed down from generation to generation. Only long term use and observation would the benefits be experienced. And now as we create ways to scientifically prove what ancient cultures have always experienced we are seeing the proof of their value.
The positive effects of plant and plant derivatives are so remarkable and impressive even without scientific studies and the use of sophisticated laboratory equipment only now shows how much more effects were already grounded to scientific rationale and findings? These intriguing facts piloted the scientific enthusiast to venture on studies that lead to the discovery of each component in plants.
Tea leaves are filled with all natural vitamins, minerals and nutrients that have supported human health for millennia. And green tea leaves are among the most healthiest unprocessed form of this age old natural medicine and refreshment.
During ancient time, green tea was used to aid digestion, stop bleeding, and cure other diseases common at that time.

To satisfy their curiosity about what really makes green tea a very powerful plant, they tried to isolate each chemical component in green tea leaf extract. They were able to find out a lot of components, which makes up the bitter, astringent, distinct flavor in green tea that gives out beneficial effects on human health.
Recently, the scientific communities were flocking to study one of the most controversial components in green tea, the Catechin EGCG. The focus of today’s health teachings were on promotive and preventive aspects, since health maintenance is much more efficient than health restoration. Because of this, a lot of supplements claiming to protect human health came out in the market. Antioxidant also became a common term. People show willingness to pay for expensive antioxidant-containing products in order to ensure longevity. Some of these antioxidant-containing products were Vitamin C and E. However, studies showed that EGCG in green tea was proven to be more potent than Vitamin C and E. The focus then turned to EGCG, a component that gives a biting taste when drinking green tea. It was studied extensively and linked directly as potential cure to various conditions afflicting human health. It has a multitude of beneficial health effects. It lowers the blood pressure and cholesterol, it burns the fats muscles by speeding up metabolism, it destroys cancer-causing oxidants and carcinogenic’s, it kills bacteria in the mouth and it lowers blood sugar level. It remedies arthritis, heart disease and a whole lot more. Until now, scientists are still unveiling the other uses of green tea for human health and vitality. Green tea products contain caffeine. It can be used to increase level of alertness and stamina needed for a day to day activity. It mildly increases urine output, preventing urinary stasis that can cause problems like formation of kidney stones. It is a component that gives bitter green tea taste. Theanine, another substance in green tea, is the reason why green tea is a relaxing drink. This chemical protects the neurons and lowers the blood pressure. Green tea is also packed with vitamins and minerals needed for the body to function normally. They were able to extract vitamin C, B2 and E, Folic acid and β-carotene. Potassium, Calcium, phosphorus and manganese which act as biological modulators are also contained in green tea leaves. Saponins in green tea protects against influenza and development of high blood pressure. Fluoride and Chlorophyll promotes oral health by protecting the teeth and deodorizing the mouth respectively. Gamma Amino Butyric Acid (GABA) is a neurotransmitter which can be provided by green tea. Studies showed that it helps lowering the pressure of the blood.
Since the scientist were able to identify various healthful components in green tea and it is now justified why a refreshing tea is considered as a super food.
