Safety and Efficacy of Herbal Tea in Type 2 Diabetics

The study will include Type 2 Diabetics who are taking only oral hypoglycemic medications (without insulin). Their therapy has to be stable for at least 3 months prior enrollment. Besides anthropometric measures, patient's glycaemia, renal and liver function will be monitored. Safety and adverse events will be closely monitored and these are the primary outcomes of the study. The main outcome measure of the effectiveness is HbA1c (glycated hemoglobin). Patients will be given detailed instructions on how to prepare the tea and the dosing. The intervention will last 3 months and during that time patients will be asked not to change their dietary or lifestyle habits.
