BACKGROUND Ethanolic extract of licorice root has been shown to reduce low-density lipoprotein (LDL) oxidation in atherosclerotic mice and in both hypercholesterolemic and normal lipidemic humans. OBJECTIVE This study examined the effect of licorice-root extract on carotid intima-media thickness (CIMT) in individuals with hypercholesterolemia. DESIGN Individuals with hypercholesterolemia (t...

background: this study compared the effect of adjunctive low dose doxycycline and licorice on gingival crevicular fluid (gcf) matrix metalloproteinase-8 (mmp-8) levels in patients with chronic periodontitis. materials and methods: in this in vivo , experimental study 39 patients with mild to moderate chronic periodontitis were selected. samples of gcf were collected from three deepest pockets a...

Because of the complicated chemical composition of traditional Chinese medicines (TCMs), their metabolic study has been a great challenge, especially when they are used in the traditional way, i.e., clinical oral dose of water decoction. Poor understanding of metabolic pathways and too low metabolite concentrations to be detected in biosamples are the major hurdles. In the present work, a three...

background herpes simplex virus 1 (hsv-1) resistance to drugs and the side effects of drugs have drawn the attention of investigators to herbal plants. objectives the main aim of the current research was to investigate the effects of glycyrrhiza glabra (liquorice root) on hsv-1. one of the objectives of the current research was to determine the efficacy and the effect of the elapsed incubation ...

BACKGROUND Rhizoma Pinelliae is the dried tuber of Pinellia ternata (Thunb.) Breit. Modern pharmacological studies have shown that Rhizoma Pinelliae has antitussive, antiemetic, glandular secretion inhibiting and antitumor effects. OBJECTIVES To optimize the processing technology of Rhizoma Pinelliae Praeparatum, and to study its anti-tumor effect. METHODS Orthogonal design method was appli...

The present work aims to characterize and quantify the phenolic composition and to evaluate the antioxidant activity of Glycyrrhiza glabra L. (commonly known as licorice) rhizomes and roots. The antioxidant potential of its methanol/water extract could be related to flavones (mainly apigenin derivatives), flavanones (mainly liquiritin derivatives), a methylated isoflavone and a chalcone, identi...

Introduction: Glycyrrhiza glabra (Licorice) has been traditionally used as a medicinal plant in Iran for treatment of diseases such as gastric ulcer and arthrosclerosis. In this study, in order to determine some of its mechanisms, effects of hydroalcoholic extract of Glycyrrhiza glabra was examined on the blood pressure in rats. Methods: Adult male rats were anesthetized via injection of pen...

Licorice botanicals are produced from the roots of Glycyrrhiza species (Fabaceae), encompassing metabolites of both plant and rhizobial origin. The composition in both primary and secondary metabolites (1°/2°Ms) reflects the physiologic state of the plant at harvest. Interestingly, the relative abundance of 1°Ms vs 2°Ms in licorice extracts remains undetermined. A centrifugal partition chromato...

licorice, the oldest chinese traditional medicine, is widely used in the treatment of human diseases. due to the deficiency of wild resource, selecting and breeding becomes a key issue to expanding the supply of licorice. spaceflight technology will become a new method for medicinal plants. the aim of this study was to investigate the effect of spaceflight on the components and anti-inflammator...
