A group of researchers from Rabe Rashid University, Marand Islamic Azad University and Agricultural and Natural Resources Research Center have found out that aqueous extract of ‎white tea can control amount of glucose ‎and lipid profile in diabetic rats.

According to an ISCA report, many researches have shown that aqueous extracts of white tea has an antioxidant properties but few studies have been conducted on the effects of diabetic and hyperlipidemic.

In this study, which its results published in the journal of Quarterly Journal of Experimental Animal Biology, Zeynab Amanzadeh, Felor Zargari and Alireza Khalilaria evaluated the effect of aqueous extract of white tea on the lipid profile and blood glucose in streptozotocin-induced diabetic rats.

In the experimental study, 32 male Wistar rats were randomly divided into 4 groups of 8 were; First group, control group that received standard diet and a daily 1ml of distilled water via gavage; the second group, streptozotocin-induced diabetic rats; the third group, healthy rats aqueous extract of white tea (1.5 percent) were consumed; the forth group, diabetic rats that were consumed aqueous extracts of white tea (1.5 percent).

Based on the research, after the treatment period (30 days) to determine blood glucose levels and lipid profile was performed and the data were analyzed with SPSS software (P<0.05). A significant decreases in serum levels of glucose, LDL, cholesterol and triglyceride and significant increase in levels of HDL and weight were observed in the group receiving aqueous extract of white tea (P<0.05).

The results showed that aqueous extract of white tea decreases serum levels of glucose, triglycerides, total cholesterol, LDL and HDL cholesterol levels significantly (P<0.05). The aqueous extract of white tea is effective for hyperglycemia and hyperlipidemia in diabetic rats.
