Clinical evaluation of a herbal antidiabetic product.
Sixty-seven diabetic patients and 12 normal subjects were selected for a clinical study with an indigenous herbal product. The study consisted of 2 phases. In phase 1 study out of 25 diabetics (both insulin dependent and non-insulin dependent) only those in the age group of 41-50 years ie, 11 cases showed lowering of mean high blood sugar level in all samples from 1/2 an-hour to 2 hours with the test drug containing guar gum, methi, tundika and mesha shringi. But in phase 2 study there was lowering of blood sugar level with the test drug and with 2 of its constituents ie, guar gum and methi when used separately in 42 non-insulin dependent diabetics. While there was some blood sugar level lowering effect with guar gum and methi when used separately in 12 normal subjects in phase 2 study, but that was not the same observed with the test drug. The results of this study indicate the efficacy of the product as an adjuvant.
