Abstract
Green tea is commonly used as a beverage worldwide, especially in China, Japan, Morocco, and Saudi Arabia. Green tea and its constituents have been considered very effective in the prevention and treatment of various diseases. It contains a variety of catechins, which show a pivotal role in the modulation of biological activities and also act as chemo preventive agents. Fibrinogen is the main constituent that format the blood clot elevated fibrinogen level raises heart disease risk by (60 to 90%) this study aimed to draw attention to the importance of healthy green tea over other kinds of tea and to explore the effect of green tea on coagulation profile. This can be achieved through experimental study. This study aimed to assess the effect of green tea consumption on coagulation profile among apparently healthy adult Sudanese individuals. In this study venous blood sample 9:1 in Trisodium citrate 3.2 %. Were collected from healthy adult controls (n=30) (12 male and 18 female) randomly selected. The Prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen test were performed by the coagulometer. There was statistical significant difference (p.<0.05) in the fibrinogen level before and after consumption of green tea (before 339.9±62.5) (after 310.6±47.9).While there was no statistical significant difference in other coagulation tests. Moreover there was statistically significance in levels of fibrinogen between males and females. The mean of fibrinogen level in male before and after were (306±55) (275±28) respectively and in female were (362±57) (343±44) respectively. This study didn’t obtain any statistical significance in fibrinogen levels between different age group.
