Oxidative stress and inflammation play important roles in disease development. This study intended to evaluate the anti-inflammatory and antioxidant potential of Echium plantagineum L. bee pollen to support its claimed health beneficial effects. The hydromethanol extract efficiently scavenged nitric oxide ((•)NO) although against superoxide (O2(•-)) it behaved as antioxidant at lower concentrat...

We examined adaptive clinal variation in seed mass among populations of an invasive annual species, Echium plantagineum, in response to climatic selection. We collected seeds from 34 field populations from a 1,000 km long temperature and rainfall gradient across the species' introduced range in south-eastern Australia. Seeds were germinated, grown to reproductive age under common glasshouse con...

Abstract Light is considered a factor that influences the seed germination of many weed species, and it can signal whether environmental conditions are favorable or not for germination. We aimed to study if there an influence light quality dormancy overcoming in Echium plantagineum L. carried out 2 x 6 factorial experiment, with without potassium nitrate followed by immersion gibberellic acid; ...

The aim of this study was to assess the efficacy and tolerability of the aqueous extract of Echium amoenum in combination with SSRIs in patients with General Anxiety Disorder (GAD). The study was an 8-week double-blind randomized clinical trial. Thirty-seven adult outpatients who met the DSM-IV-TR criteria for GAD based on the structured clinical interview participated in the trial. In this stu...

Putative activity of hydroalcoholic and aqueous infusion extracts of Echium amoenum L. was investigated in mice using the rotarod model of motor coordination and the elevated plus maze model of anxiety. The extracts were administered intraperitonealy (i.p.) once, one hour before performing the tests. Preliminary phytochemical study of the plant, with standard procedures, showed that it contains...
