The evaluation of the body weight lowering effects of herbal extract thi on exercising healthy overweight humans: A randomized double-blind, placebo-controlled trial

Abstract

We investigated the effects of herbal extracts, a mixture of Scutellariae Radix and Platycodi Radix containing the active ingredients Baicalin and Saponin (target herbal ingredient (THI)), on lowering body weight. The present study was a prospective, randomized, double-blind, and placebo-controlled trial carried out at the outpatient department of a hospital over a period of 2 months. Group 1 patients (n = 30) received THI, and group 2 patients (n = 23) received placebo three times a day before meals. Weight, waist circumference, BMI, total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, and glucose were measured at baseline and again at the 2nd month. For safety evaluation, various hematological and biochemical parameters were assessed. Values of mean change of weight in the THI-treated group were - 1.16 ± 1.41 kg and in the placebo-treated group were - 0.24 ± 1.70 kg, respectively. The difference in mean change of weight in the THI-treated group compared with that in the placebo-treated group was statistically significant (P < 0.05). The incidence of subjective and objective adverse drug reactions was insignificant (P > 0.05). THI was statistically significant in its effectiveness on the weight loss. © 2013 Soo Hyun Cho et al.
