OBJECTIVE: The use of dietary supplements has increased and is associated with adverse effects. Indications for use include recreation, body image concerns, mood enhancement, or control of medical conditions. The risk of adverse effects may be enhanced if agents are used improperly. The objective of this study was to determine the frequency of abuse and misuse of 4 dietary substances among adolescents reported nationally to poison centers. Secondary outcomes included an assessment of medical outcomes, clinical effects, location of treatments provided, and treatments administered...

Objective: To evaluate the wound-healing activity of oil of Hypercium perforatum (St. John's wort), in excision wounds of male white rats. Approach: The current methods of wound management involve the use of antibiotic creams. The search for more natural materials for the purpose of healing of wounds has led to the discoveries of potential agents prepared from plant extracts. Hyperforin and Hypericin are important phytochemical constituents found in H. perforatum, which have been highlighted for their antimicrobial, antiviral, and anti-inflammatory properties in recent times...

BACKGROUND: The ready availability and use of dietary supplements (DS) by the public means that healthcare professionals require education in this area. In the Republic of Serbia, education related to use of DS is included in undergraduate medical training and it is therefore important to assess the effectiveness of this education. The aim of our survey was to investigate the influence of pharmacological education on the use, attitudes and perceptions of risks associated with DS among medical students...

OBJECTIVES: People with diabetes turn to over-the-counter (OTC) medicines for many ailments. The focus of this brief review is the impact common OTC medicines might have on this group of patients. METHODS: Three types of OTC medicines were selected as most deserving of attention: 3 herbal agents, nonsteroidal anti-inflammatory drugs (NSAIDs) and cough/cold products. Existing literature was used to determine precautions that might be in order. RESULTS: Herbal/natural agents with the potential to impact blood sugar have been identified in various reports...

BACKGROUND: The use of herbal medicinal products (HMPs) is common among older adults; however, little is known about concurrent use with prescription drugs, as well as potential interactions associated with such combinations. OBJECTIVE: The aim of this systematic review was to identify and evaluate the literature on concurrent prescription and HMP use among older adults to assess prevalence, patterns, potential interactions and factors associated with this use. METHODS: Systematic searches were conducted in the MEDLINE, PsycINFO, EMBASE, CINAHL, AMED, Web of Science and Cochrane databases from inception to May 2017 for studies reporting concurrent use of prescription medicines with HMPs in adults ≥ 65 years of age...

Heavy metals polluting the natural environment are absorbed by plants. The use of herbs as components of cosmetics may pose a health risk for humans. The aim of the study was to determine the concentrations of Pb, Cd and Hg in selected species of herbs (horsetail Equisetum arvense, nettle Urtica dioica, St. John's wort Hypericum perforatum, wormwood Artemisia absinthium, yarrow Achillea millefolium, cottonwood Solidago virgaurea) self-collected from the natural environment in two different locations, and purchased in stores on the territory of Poland...

OBJECTIVES: St John's wort extract (SJW) and its component hyperforin (HPF) were shown to potently inhibit cytokine-induced STAT-1 and NF-κB activation in pancreatic β cells and protect them against injury. This study aimed at exploring the time course of STAT-1 inhibition afforded by these natural compounds in the β-cell line INS-1E. METHODS: INS-1E cells were pre-incubated with SJW extract (2-5 μg/ml) or HPF (0.5-2 μm) and then exposed to a cytokine mixture...

Aluminum (Al) is a neurotoxicant and cause β-amyloid (Aβ) peptides aggregation and tau hyperphosphorylation. Hyperforin (HF) is one of the major active constituents of the extracts of St. John's Wort (Hypericum perforatum), can treat Alzheimer's disease (AD) and other diseases involving peptide accumulation and cognition impairment. To determine the effects of HF on Al-induced Aβ formation and tau hyperphosphorylation, PC12 cells were cultured and treated with Al-malt (500μM) and/or HF (1μM). The results showed that HF treatment significantly attenuated Al-malt-induced Aβ1-42 production by reducing the expressions of APP, BACE1 and PS1, while increasing the expressions of sAPPα, ADAM9/10/17, and tau phosphorylation in PC12 cells...

The occurrence of potentially toxic pyrrolizidine alkaloids (PAs) in herbal medicines (HMs) is currently intensely being discussed in Europe. Pyrrolizidine alkaloids, particularly the 1,2-unsaturated PAs, are undesired compounds in HMs due to their potential hepatotoxic and carcinogenic properties. In this study, 98 widely patronized HMs from six popular German retail supermarkets/drugstores, as well as from pharmacies, were analyzed by high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry for the presence of PAs...

Hypericum perforatum L. (Hypericaceae), or St. John's Wort, is a well-known medicinal herb often associated with the treatment of anxiety and depression. Additionally, an oil macerate (Oleum Hyperici) of its flowering aerial parts is widely used in traditional medicine across the Balkans as a topical wound and ulcer salve. Other studies have shown that Oleum Hyperici reduces both wound size and healing time. Of its active constituents, the naphthodianthrone hypericin and phloroglucinol hyperforin are effective antibacterial compounds against various Gram-positive bacteria...

Background: Plant extracts have been used in traditional medicine for the treatment of various maladies including neurological diseases. Several central nervous system receptors have been demonstrated to interact with plant extracts and components affecting the pharmacology and thereby potentially playing a role in human disease and treatment. For instance, extracts from Hypericum perforatum (St. John's wort) targeted several CNS receptors. Similarly, extracts from Piper nigrum, Stephania cambodica, and Styphnolobium japonicum exerted inhibition of agonist-induced activity of the human neurokinin-1 receptor...

St. John's wort (SJW) is a common medicinal herb used for the treatment of mild to moderate depression. Hyperforin, one of the chief components of SJW, plays an important role in the induction of cytochrome P450 enzymes (CYP) and P-glycoprotein transporter (P-gp), and therefore, affects the pharmacokinetics of various drugs. There are several clinical studies demonstrating the interaction of SJW with the metabolism of conventional drugs which may cause life-threatening events. Areas covered: This review focuses on human studies that have evaluated pharmacokinetic alterations of conventional drugs in concomitant use with different SJW preparations...

Hyperforin, a pharmacologically active component of the medicinal plant Hypericum perforatum (St. John's wort), has been shown to be neuroprotective against acute ischemic stroke. However, the underlying mechanisms are still unclear and need to be fully elucidated. C57BL/6 wildtype (WT) mice or interleukin (IL)-17A knock-out mice were subjected to middle cerebral artery occlusion (60 minutes) followed by reperfusion for 72 hours. Hyperforin (0.5 μg) was injected slowly into the right ventricle of WT mice 1, 24 and 48 hours after middle cerebral artery occlusion (MCAO) onset...

Nearly 25% of U.S. adults report concurrently taking a prescription medication with a dietary supplement. Some supplements, such as St. John's wort and goldenseal, are known to cause clinically important drug interactions and should be avoided by most patients receiving any pharmacologic therapy. However, many other supplements are predicted to cause interactions based only on in vitro studies that have not been confirmed or have been refuted in human clinical trials. Some supplements may cause interactions with a few medications but are likely to be safe with other medications (e...

Hyperforin is a major metabolite of the medicinal plant Hypericum perforatum (St. John's Wort) and has recently been found in hormone induced root cultures. The objective of this study is to identify a downstream process for the production of a hyperforin-rich extract with maximum extraction efficiency and minimal decomposition. The maximum extraction time was found to be 60min. The comparison of two equipment concepts for the extraction and solvent evaporation was performed employing two different solvents...
