Abstract
Fresh, unprocessed Green teaCamelia sinensisis commonly consumed in several regions of Saudi Arabia. Green tea has been used for centuries as a medical drink. The aim of the study is to investigate the effect of fresh, unprocessedgreen tea on liver function,cholestrol,triglyceride,thyroid stimulating hormone (TSH),and cortisol and in humans. Atotal of 25 healthy adult subjects age range (20-30) years old participated in this study as volunteers.Fresh, unprocessed green tea containing approximately 25 whole stem and leaves (approximately 15g)were given to each volunteer to be used for two weeks with daily consumption between 3-5 cups/day. Pre-drinking fasting blood samples were collected from each volunteerand another fasting blood samples werecollcted again after finshing the period of drinking. The serum collected were assayed for; lipid profile (cholesterol and triglycerides), liver function (total protein,albumin,Alkaline phospatase(ALP), Aspartate aminotransferase(AST),Alanine aminotransferase(ALT), Gamma-glutamyl transferase(GGT) and total bilirubin),thyroid stimulating hormone (TSH) and cortisol.The results showed that unprocessed green tea causes significant increase in albumin,Abumin/ Gloulin ratioand TSH, while it caused significant decrease inglobulins,Triglyceride,Cholestroland ALP.We concluded that fresh unprocessed green tea has powerful specific metabolic activities of intestine, liver, and lipids comparable to green processed tea to improve their functions.
