The green tea comes from the Camellia Sinensis plant, which grow in high altitude areas in countries with hot and humid climates such as Japan, China, and India.
In the western world, green tea is increasingly popular and demanded because more and more people know its healthy properties. One of the reasons why tea is possibly so well known is because of its content in teína, a stimulating substance.
The leaves of this variety of tea are, in fact, dark green and differ from the leaves of white, yellow, oolong and black teas.
The black tea also comes from Camellia sinensis although the process after cutting the leaves is different.
How to make green tea and black tea different?
In contrast, the leaves harvested for green tea are not always left to wither. A fundamental process to distinguish green tea, however, is the application of heat before rolling and drying or baking the leaves.
The Japanese method requires that the leaves are steamed briefly and the Chinese method consists of toasting the leaves in large pans.
This step (both ways) stops oxidation of the tea because it prevents the rupture of the veins in the leaves and the release of their enzymes. Therefore, many of its essential nutrients remain intact, and its color is also maintained.
During the production of black tea, the harvested leaves are placed in trays in the upper part of the factory and left to wilt in the air, at temperatures between 25-30 ° C. This process requires between 10 and 16 hours for the humidity of the leaves to evaporate.
Afterward, the dried leaves are rolled – or cut and rolled to get smaller pieces – with the use of a machine to break the structure and release enzymes that initiate the oxidation process. Next, the leaves are fermented and dried or baked.

The healing properties of green tea have been part of the cultures of the East for more than 4000 years, and in the rest of the world, we are increasingly surprised by the health benefits that this infusion provides.
- The green tea is a rich source of polyphenols. Polyphenols are flavonoids with powerful antioxidant properties that neutralize the harmful effects of free radicals. The catechins (other polyphenols) have been shown to have antiangiogenic activity and anti-inflammatory estimuladoreas immune system that are responsible for their anti-cancer effect.
- Green tea has anti-inflammatory properties to prevent allergic reactions and episodes of asthma. Its tannins also have an anti-inflammatory effect.
- It fights caries and periodontal diseases for its antibacterial properties.
- Protects the heart, reducing the risk of cardiovascular diseases, reduces blood pressure, prevents atherosclerosis, antioxidant flavonoids protect against circulatory problems in addition to reducing the levels of “bad” cholesterol LDL and triglycerides and increase the “good” HDL cholesterol.
- It improves physical resistance; this helps to keep fit and lose weight, and thus also reduces the risk of cardiological diseases and diabetes.
- Improves peripheral circulation: relieves varicose veins, microvesicles, and cold hands/feet because the phenolic compounds help strengthen blood vessels.

Recommended daily allowance
Enjoy the benefits of green tea by consuming 2 to 4 cups a day.
We must bear in mind that the infusion time of the leaves influences the polyphenol content of that infusion (in infusions of 8-10 minutes we can obtain the maximum of catechins, while in a 5-minute infusion only 20% is extracted of those catechins).
And of course, the quality of the tea also influences its medicinal properties, since better properties of green tea contain up to 60 times more polyphenols than infusions of poorer quality and with short infusions.
* Consult a doctor in case of sensitivity to caffeine/thein or case of depression or anxiety.
Preparation of green tea
Serve the tea with boiling filtered water or wait a few minutes if you prefer a less bitter taste. It is advisable to leave the leaves to rest in prolonged infusions to obtain the maximum benefit of their properties. However, the bitterness of strong green tea is not pleasant for some people.
