Hypericum perforatum, commonly known as St. John’s Wort, has been found to exhibit many medicinal, especially anti-depressant, properties. Hypericin is thought to be the main chemical constituent responsible for H. perforatum’s medicinal properties. We report here the ability of H. perforatum and hypericin to inhibit the growth of mouse mammary cancer CRL2539 cells. H. perforatum, at concentrat...

Purpose. The present study evaluated the effect of Hypericum perforatum dry extract in an experimental model of binge eating (BE). Methods. BE for highly palatable food (HPF) was evoked in female rats by three 8-day cycles of food restriction/re-feeding and acute stress on the test day (day 25). Stress was induced by preventing access to HPF for 15 min, while rats were able to see and smell it....

Background & Aim: St John's wort (Hypericum perforatum L.) contains hypericin and hyperforin as the main components of the extract that binds with GABA and sigma opioid receptors. This herb has many pharmacological effects, including analgesic, sedative, soothing, antispasmodic, anticonvulsant, anti-depressant, and anti-bacteria. In this study examined the effect of two concentrations of Hyperi...

AIM To evaluate the effects of montelukast and Hypericum perforatum against ischemia/reperfusion (I/R)-induced intestinal damage. MATERIALS AND METHODS Twenty-eight hamsters were divided into 4 groups following midline abdominal laparotomy: control group (n = 7), I/R group (n = 7), montelukast and I/R (MIR) group (n = 7), and Hypericum perforatum and I/R (HPIR) group (n = 7). After 60 min of ...

Hypericum perforatum, is a plant which blooms between july and september at farms, borders of roads and woods, top of hills and grasslands, whose anti-inflammatory effects are shown in various studies. It is shown that cigarette smoke causes increase in inflammation mediators on lung. Due to this reason, we planned a study to examine the protective effects of Hypericum perforatum aganist smoke ...

The Iowa Center for Research on Botanical Dietary Supplements seeks to optimize Echinacea, Hypericum, and Prunella botanical supplements for human-health benefit, emphasizing antiviral, anti-inflammatory and anti-pain activities. This mini-review reports on ongoing studies on Hypericum. The Center uses the genetically diverse, well-documented Hypericum populations collected and maintained at th...

One of the top-selling medicinal products worldwide is Hypericum perforatum (St. John's Wort). Despite its cosmopolitan distribution and utilization, little is known regarding the relationship of the bioactive compounds in H. perforatum to the plants from which they are purportedly derived. In this study, amplified fragment length polymorphism (AFLP) analysis of 56 Hypericum accessions, represe...

The present study has been evaluated the neuroprotective effect of Hypericum perforatum extract on the reaction of astrocytes in mice brain treated with an intraperitoneal injection of 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (20 mg/kg with 2 hr intervals). Treatment with Hypericum perforatum extract (HPE) resulted in an inhibition of monoamine oxidase-B (MAO-B) activity and reduced ...

Adhyperforin is a novel constituent of Hypericum perforatum L., but its antidepressant-like activity remains unclear. To explore that, several well-validated animal models of depression as well as neurotransmitter reuptake and transporter binding assays were conducted. The results showed adhyperforin could reduce the immobility time of mice in the forced swimming test and tail suspension assay,...
