The 21 Proven Health Benefits of Green Tea, Side Effects and more

Green Tea has always been a royal tradition in Ancient China. It was the beverage of the Emperor, who insisted on giving this magical potion to his people. 

In modern times, the consumption of Green Tea has been a recent year’s innovation. Companies around the world deviated from the production of world-famous black Tea. Green Tea is the most unprocessed beverage you may find on the market.

Many people love it for its unique taste and aroma. However, scientists support that this “superfood” can help you in losing weight and keep a healthy balance. That is why it would be useful to have all the information about it and decide for yourself.

What is Green Tea?

Renowned for its uncomparable health benefits, Green Tea is the highest consumed beverage in Eastern Asian countries. Attached to the Japanese culture, there are more than nine varieties to enjoy.

It is the direct product of the plant Camellia Sinensis, which originated in China. People used to cultivate these plants in large acreage around the country and harvest its leaves.

Englishmen who conquered China in the late 18th Century tried to produce a variation. The Black Tea evolved as a result of further processing and oxidization of the Green Tea leaves.

The famous Black Tea has the same amount of theophylline, which is the chemical analog of caffeine in tea beverages. Japanese people took the Camellia Sinensis plants to their country. 

Then they identified that boiling the tea leaves with water offered a healthy beverage. It was the first time that Green Tea appeared in Japanese society, and people adopted the habit of drinking its extract.

From that point, Japanese people developed nine different varieties of Green Tea.

All of these teas have sound effects on your health. Each cup relieves you from the pressure of daily life and helps you adopt a healthy way of living.

2-Drying

The leaves should get dried to ensure that fermentation from enzymes doesn’t happen. Japanese are using steam to dry each leave separately for 30 to 90 seconds.

3-Shaping

After drying the tea leaves, a machine rolls them and places them into unique pots or sachets. Tea leaves can be shredded and ground into small granules to take the final form for people who drink their hot beverage using small dipping bags.

The recommended dosage of Green Tea

Drinking three to five cups of Green Tea per day can provide you with 180 mg of catechins and at least 60 mg of L-Theanine. You can also have the caffeine levels you need to keep you up all day.

Remember that if you go over the five cups of Green Tea per day, you will have stomach issues. EGCG is the most popular of the catechins molecule, but it can result in liver damage if you take too much without eating first.

In case of overdose, then you need to stop taking green Tea immediately. Overdose can give you the following symptoms:

  • Nervousness
  • Diarrhea
  • Irregular Heart Beats (Arrhythmia)
  • Dizziness
  • Insomnia

Always talk to your dermatologist to find the best cure for skin rashes provoked by Green Tea creams.

3-Stomach upset and constipation

They are the common side effects of Green Tea and any other type of teas like the Black one. EGCG and catechins can reduce the mobility of your intestine and worsen your pre-existing constipation problems. 

In case you feel like vomiting or have a stomach upset, you need to stop drinking Green Tea immediately and ask for medical help.
