How not to drink green tea?

Now you know who is contraindicated in green tea. However, it should be noted that before buying this product, it is necessary to pay attention not only to its harm, but also to how it should be used correctly. After all, even in the absence of contraindications, improperly drunk tea can cause significant harm to the human body.

• Green tea taken on an empty stomach can upset your digestion quite easily.
• You can not drink the presented drink with glaucoma.
• If you decide to give green tea to your child, then you should remember that children under 12 years old can only drink it in a weakly brewed form.
• Green tea is also contraindicated for people with an enlarged thyroid gland.



• You can not drink tea of poor quality or with an expiration date. That is why you should not save on it, but rather spend money and buy a real and fresh product.
• Green tea should not be too hot when consumed. After all, the high temperature of such a drink cancontribute to the appearance of inflammation of the internal organs due to burns.

Brew process

Preparation of any tea drink, including green, is called brewing. To do this, take about 2 g of dry matter and pour it with about 100 ml of boiled water.

It should also be noted that the brewing process may vary markedly depending on which grade of product you purchased. For example, high-quality tea uses a large amount of dry leaf, which can be brewed several times in a short time.

Beverage preparation time and water temperature are also different for different types of tea. The highest brewing temperature is 81-87°C and the longest time is 2-3 minutes. As for the lowest value, it is 61-69°C and 30 seconds respectively.

As a rule, low-quality tea is brewed at higher temperatures and much longer than high-quality tea. It is from this observation that you can determine which product was sold to you in the store.

Finally, I would like to add that if green tea is brewed for too longand in boiling water, it will become astringent and bitter, regardless of its variety and quality.
