Evaluation of aCrataegus-Based Multiherb Formula for Dyslipidemia: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial

Abstract

Background.We for the first time examined the effects of a multiherb formula containingCrataegus pinnatifida(1 g daily),Alisma orientalis,Stigma maydis,Ganoderma lucidum,Polygonum multiflorum, andMorus albaon plasma lipid and glucose levels in Chinese patients with dyslipidemia.Methods.In this randomized, double-blind, placebo-controlled study, 42 patients were randomized at a ratio of 1 : 1 to receive the herbal formula or placebo for 12 weeks and 40 patients completed the study. Lipid profiles, glucose, glycated haemoglobin (HbA1c), and laboratory safety parameters were performed before and after treatment.Results.The difference in the changes in low-density lipoprotein cholesterol (LDL-C) levels between placebo and active treatment (−9%) was significantly(P<0.05)better with active treatment. HbA1c levels significantly decreased by −3.9% in the active treatment group, but the change was not significantly different from that with placebo (−1.1%)(P=0.098). There were no apparent adverse effects or changes in laboratory safety parameters with either treatment.Conclusions.The multiherb formula had mild beneficial effects on plasma LDL-C after 12-weeks treatment in subjects with dyslipidemia without any noticeable adverse effects.
