Green Tea and Its Numerous Health Benefits

Abstract

Green tea is one of the most popular antioxidant drinks in the world. To make green tea, you must first remove the leaves from Camellia sinensis. A form of tea made from unoxidized green leaves from a tea plantation is called green tea. Several other studies have been undertaken over the past year to evaluate whether consuming green tea and extracts has any health benefits. In order to get the health benefits of green tea, the nutrients in the tea must be absorbed. Green tea’s flavonoids and caffeine, which serve to accelerate the elimination of metabolites, contribute to the antioxidant function of green tea. Cancer, heart disease, and aging appear to be the main diseases to be reduced or prevented by these antioxidants. The pharmaceutical and culinary industries can use green tea due to its high potency and lack of adverse effects. Green tea is touted as a natural remedy for a wide range of health issues. Through this, we can better understand the immediate benefits of green tea. Prescription green tea components are discussed along with their antioxidant, anticancer, and antiviral actions in relation to the treatment of cardiovascular diseases (CVD).

“…Then, it spread to many different neighboring regions, and in the 19th century it traveled West with European explorers, where today its Great Britain’s national beverage (along with black tea) [ 188 , 189 ]. Today, green tea is one of the most popular drinks in the world and the least oxidized compared to other teas [ 190 ]. In the last 30 years, the popularity of green tea has greatly increased and has been extensively investigated for its many health benefit including its protective role against various types of human cancers [ 10 , 12 , 119 , 190 , 191 , 192 , 193 ]; however, this narrative overview is focused on BPH.…”

“…Green tea comes from the Camellia sinenis plant that is an evergreen shrub or small tree native to East Asia and Southeast Asia, where fresh leaves contain caffeine (around 4 percent), are a rich source of polyphenols and catechins along with theanine, vitamins (B2, C, E, and folic acid), saponins, GABA and minerals (potassium, calcium, phosphorus, etc.) [ 190 , 194 ]. The polyphenols in green tea are credited with beneficial properties against several diseases/disorders via biological and molecular mechanisms [ 190 , 195 ].…”

“…The distinctive polyphenolic compounds present in green tea are called catechins, which make up 80–90% of the flavonoids and about 40% of the water- soluble solids [ 190 ]. The four major catechins are (-)-epicatechin (EC), (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECG), and (-)-epigallocatechin gallate (EGCG) [ 190 , 195 ]. The distribution of the catechins varies; however, EGCG accounts for around 60%, followed by EGC at 20%, ECG at 14% and EC at 6% [ 190 , 195 ] ( Figure 11 ).…”
