Green Tea – Functions, Effectiveness, Preparation, Dosages, Side-Effects
Green Tea – All you Need To Know
Green tea comes from the Camellia Sinensis plant. From dried leaves to dried buds, every part of this plant is used to make various teas. The leaves undergo the process of steam and pan fry before drying them to make green tea. Other teas, such as black tea and oolong tea, go through fermentation (black tea) or partial fermentation (oolong tea) procedures (oolong tea). People frequently consume green tea as a beverage.
Green tea is sometimes used as a drink or supplement to treat excessive levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia) and high blood pressure, as well as to avoid heart disease and cancers of the uterine lining (endometrial cancer) and ovarian cancer. It’s also used for a variety of other ailments, but there’s no scientific evidence to back it up. Green tea is consumed by many people across all countries. So, let’s learn about it more.
Functions of Green Tea
The leaf bud, leaf, and stem are all useful elements of green tea. It is made by boiling fresh leaves at high temperatures without being fermented. It can keep key compounds known as polyphenols during this process, which appear to be responsible for many of green tea’s advantages. Polyphenols may help reduce joint degeneration by reducing inflammation and swelling and protecting cartilage between the bones. They also appear to fight human papillomavirus (HPV) infections and reduce abnormal cell proliferation in the cervix (cervical dysplasia). Research to now has not been able to explain how this works.
It is used for the treatment of genital warts too. The tea’s caffeine enhances thinking and alertness, increases urine production, and may improve the function of brain messengers critical in Parkinson’s disease. Caffeine is thought to activate the neurological system, heart, and muscles by increasing the release of “neurotransmitters,” which are molecules found in the brain.

Preparation of Green Tea
The brewing temperature and steeping time guidelines may differ depending on the type and variety of green tea you wish to brew. If the tea packaging does not include brewing instructions, ask your tea dealer for advice.
Here are some general tea-making guidelines to remember while making it. Use filtered water that is fresh, pure, and cool. These teas are usually made in short infusions at 160 to 180 degrees. Don’t let your tea become too hot! If the water is overly hot, especially for this tea, the bitterness and astringency of the tea will be released more quickly. If you don’t have an electric kettle with temperature control, let the water cool before pouring it over the leaves. It depends on the tea, but a good bet is to use roughly 2 grams of loose leaf tea per 8 oz. cup of water. Use the steeping instructions on your tea package if it has them. To maintain all of the heat in the steeping vessel, cover the steeping tea.
Note: For an early harvest, more delicate teas, steep for 30 to 60 seconds; for regular harvest, more powerful teas, steep for 2 to 3 minutes. The majority of high-quality loose leaf teas can be steeped more than once.
Dosages of Green Tea
There have been no definitive studies on how much green tea to drink each day to get the most benefit. All of it depends on one’s health and preferences. Every day, different amounts of this nutritious tea will help you in different ways. Those who drank one to three cups per day, for example, had a decreased risk of stroke and heart disease than those who drank less than one cup per day, according to controlled research. Women who consumed more than 5 cups of coffee each day were less likely to get stomach cancer. It’s excellent to have green tea in your diet, but as long as you drink a cup or more every day, that’s fine!
