The Goodness of Green Tea: Nature’s Own Herb

Tea is one of the most consumed drink around the world, produced from the leaves of the Camellia Sinensis plant. It is viewed as a “hostile to maturing refreshment.”

You’ve presumably heard a ton about the medical advantages of green tea — stacked with cancer prevention agents and supplements that are extraordinary for your body and psyche. Green tea is a rich source of herbal plant products that contains a high medicinal value. 

Consumption of green tea has been found to be linked to the prevention of various types of health problems, including different types of cancer such as lung cancer, colon cancer, mouth cancer, esophageal cancer, colon cancer, and pancreatic cancer.

Other health problems that can be prevented through the consumption of green tea include obesity, heart attack, high cholesterol, etc.

Medically polyphenols are the most relevant constituents of green tea, flavonoids being the most important and catechins are the most pertinent flavonoids.

Primarily, there are four main types of catechins that are found in green tea – epicatechin (EC), epicatechin-3-gallate (ECG), epigallocatechin (EGC), and epigallocatechin-3-gallate (EGCG).

Green tea also contains other compounds such as saponins, tannins, and vitamins and multiple studies suggest that green tea can have various actions on the body such as antioxidant, anti-inflammatory, and hypocholesterolemia. These effects of green tea are primarily due to the impact of catechin and gallic acid.

The herbal wonder of nature is an amazing herb that contains many substances which work wonder in treating and preventing multiple health problems. Some of the health problems that can be prevented using green tea are as follows:

Cardiovascular Disease 

There is no doubt in saying that cardiovascular disease is one of the leading cause of death throughout the world and is associated with reduced quality of life. Many types of research have been conducted to understand the role of herbs in the prevention and treatment of cardiovascular disease. It was found that green tea is one of the herbs that have a significant impact on cardiovascular health. 

Cardiovascular disease is associated with increased mortality as well as increased morbidity rate. Green tea extracts prevent the development of cardiovascular diseases and consumption of this beverage contributes to an increase in the overall life expectancy. Green tea polyphenols have been shown to play a major role in preventing the occurrence of cardiovascular disease.

According to one of the studies, a decrease in the death rate due to cardiovascular disease was noticed in people who consumed green tea and researchers stated that the effects of green tea in reducing cardiovascular disease are primarily attributed to the green tea catechins. 

Diabetes Mellitus

Diabetes mellitus is one of the diseases whose prevalence is increasing at an alarming rate and avoiding its treatment can result in its amplification. Diabetes mellitus is a chronic disease which results due to the high blood glucose level in the body and is affecting the people of all age.

It occurs either due to the inability of the pancreas to produce an adequate amount of insulin or due to an inability of the body to use produced insulin effectively. Insulin is a hormone that plays an important role in the regulation of glucose in the body. 

Green tea has been known to have many beneficial effects on diabetes mellitus and this is due to the compounds present in it. The compounds of green tea can have an impact on glucose metabolism by several mechanisms.

Green tea has an ability to stimulate insulin secretion from the pancreatic cells, inhibits carbohydrate digestion and glucose absorption in the intestine, uptake of glucose in the insulin-sensitive tissues and the modulation of hepatic glucose output. 

Investigations have detected that oxidative stress plays a major role in producing the adverse effects of diabetes mellitus. Oxidative stress is associated with the damaging effect of reactive oxygen species. Studies have shown that green tea has the ability to affect the levels of reactive oxygen species.
