About

Nearly 25% of the world's population relies on traditional medicinal systems but for professionals their effectiveness and even more safety are the main concern. Therefore, the aim of this preliminary study is to assess safety and effectiveness of herbal tea mixture on the control of glycaemia in Type 2 diabetics.The mixture consists of nine plants which have well-documented traditional use for the control of glycaemia.

Full description

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.
