Park JD. Metabolism and drug interactions of Korean ginseng based on the pharmacokinetic properties of ginsenosides: Current status and future perspectives. J Ginseng Res 2024; 48:253-265. [PMID: 38707645 PMCID: PMC11068998 DOI: 10.1016/j.jgr.2024.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 02/21/2024] [Accepted: 02/24/2024] [Indexed: 05/07/2024] Open
Abstract
Orally administered ginsenosides, the major active components of ginseng, have been shown to be biotransformed into a number of metabolites by gastric juice, digestive and bacterial enzymes in the gastrointestinal tract and also in the liver. Attention is brought to pharmacokinetic studies of ginseng that need further clarification to better understand the safety and possible active mechanism for clinical application. Experimental results demonstrated that ginsenoside metabolites play an important role in the pharmacokinetic properties such as drug metabolizing enzymes and drug transporters, thereby can be applied as a metabolic modulator. Very few are known on the possibility of the consistency of detected ginsenosides with real active metabolites if taken the recommended dose of ginseng, but they have been found to act on the pharmacokinetic key factors in any clinical trial, affecting oral bioavailability. Since ginseng is increasingly being taken in a manner more often associated with prescription medicines, ginseng and drug interactions have been also reviewed. Considering the extensive oral administration of ginseng, the aim of this review is to provide a comprehensive overview and perspectives of recent studies on the pharmacokinetic properties of ginsenosides such as deglycosylation, absorption, metabolizing enzymes and transporters, together with ginsenoside and drug interactions.

Le TT, McGrath SR, Fasinu PS. Herb-drug Interactions in Neuropsychiatric Pharmacotherapy - A Review of Clinically Relevant Findings. Curr Neuropharmacol 2022; 20:1736-1751. [PMID: 34370637 PMCID: PMC9881059 DOI: 10.2174/1570159x19666210809100357] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 07/23/2021] [Accepted: 08/04/2021] [Indexed: 11/22/2022] Open
Abstract
The management of neuropsychiatric disorders relies heavily on pharmacotherapy. The use of herbal products as complimentary medicine, often concomitantly, is common among patients taking prescription neuropsychiatric drugs. Herb-drug interaction, a clinical consequence of this practice, may jeopardize the success of pharmacotherapy in neuropsychiatry. Besides the wellknown ability of phytochemicals to inhibit and/or induce drug-metabolizing enzymes and transport proteins, several phytoconstituents are capable of exerting pharmacological effects on the central nervous system. This study reviewed the relevant literature and identified 13 commonly used herbal products - celery, echinacea, ginkgo, ginseng, hydroxycut, kava, kratom, moringa, piperine, rhodiola, St. John's wort, terminalia/commiphora ayurvedic mixture and valerian - which have shown clinically relevant interactions with prescription drugs used in the management of neuropsychiatric disorders. The consequent pharmacokinetic and pharmacodynamic interactions with orthodox medications often result in deleterious clinical consequences. This underscores the importance of caution in herb-drug co-medication.

Abstract
BACKGROUND Stroke is the third leading cause of early death worldwide. Most ischaemic strokes are caused by a blood clot blocking an artery in the brain. Patient outcomes might be improved if they are offered anticoagulants that reduce their risk of developing new blood clots and do not increase the risk of bleeding. This is an update of a Cochrane Review first published in 1995, with updates in 2004, 2008, and 2015. OBJECTIVES To assess the effectiveness and safety of early anticoagulation (within the first 14 days of onset) for people with acute presumed or confirmed ischaemic stroke. Our hypotheses were that, compared with a policy of avoiding their use, early anticoagulation would be associated with: • reduced risk of death or dependence in activities of daily living a few months after stroke onset; • reduced risk of early recurrent ischaemic stroke; • increased risk of symptomatic intracranial and extracranial haemorrhage; and • reduced risk of deep vein thrombosis and pulmonary embolism. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (August 2021); the Cochrane Database of Systematic Reviews (CDSR); the Cochrane Central Register of Controlled Trials (CENTRAL; 2021, Issue 7), in the Cochrane Library (searched 5 August 2021); MEDLINE (2014 to 5 August 2021); and Embase (2014 to 5 August 2021). In addition, we searched ongoing trials registries and reference lists of relevant papers. For previous versions of this review, we searched the register of the Antithrombotic Trialists' (ATT) Collaboration, consulted MedStrategy (1995), and contacted relevant drug companies. SELECTION CRITERIA Randomised trials comparing early anticoagulant therapy (started within two weeks of stroke onset) with control in people with acute presumed or confirmed ischaemic stroke. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials for inclusion, assessed trial quality, and extracted data. We assessed the overall certainty of the evidence for each outcome using RoB1 and GRADE methods. MAIN RESULTS We included 28 trials involving 24,025 participants. Quality of the trials varied considerably. We considered some studies to be at unclear or high risk of selection, performance, detection, attrition, or reporting bias. Anticoagulants tested were standard unfractionated heparin, low-molecular-weight heparins, heparinoids, oral anticoagulants, and thrombin inhibitors. Over 90% of the evidence is related to effects of anticoagulant therapy initiated within the first 48 hours of onset. No evidence suggests that early anticoagulation reduced the odds of death or dependence at the end of follow-up (odds ratio (OR) 0.98, 95% confidence interval (CI) 0.92 to 1.03; 12 RCTs, 22,428 participants; high-certainty evidence). Similarly, we found no evidence suggesting that anticoagulant therapy started within the first 14 days of stroke onset reduced the odds of death from all causes (OR 0.99, 95% CI 0.90 to 1.09; 22 RCTs, 22,602 participants; low-certainty evidence) during the treatment period. Although early anticoagulant therapy was associated with fewer recurrent ischaemic strokes (OR 0.75, 95% CI 0.65 to 0.88; 12 RCTs, 21,665 participants; moderate-certainty evidence), it was also associated with an increase in symptomatic intracranial haemorrhage (OR 2.47; 95% CI 1.90 to 3.21; 20 RCTs, 23,221 participants; moderate-certainty evidence). Similarly, early anticoagulation reduced the frequency of symptomatic pulmonary emboli (OR 0.60, 95% CI 0.44 to 0.81; 14 RCTs, 22,544 participants; high-certainty evidence), but this benefit was offset by an increase in extracranial haemorrhage (OR 2.99, 95% CI 2.24 to 3.99; 18 RCTs, 22,255 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS Since the last version of this review, four new relevant studies have been published, and conclusions remain consistent. People who have early anticoagulant therapy after acute ischaemic stroke do not demonstrate any net short- or long-term benefit. Treatment with anticoagulants reduced recurrent stroke, deep vein thrombosis, and pulmonary embolism but increased bleeding risk. Data do not support the routine use of any of the currently available anticoagulants for acute ischaemic stroke.

[PMID: 34356471 PMCID: PMC8301032 DOI: 10.3390/biology10070616] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Revised: 06/18/2021] [Accepted: 06/23/2021] [Indexed: 12/11/2022]
Abstract
(1) Background: Cardiovascular disease (CVD) is a major public health concern worldwide and a key cause of morbidity and mortality in developed countries. Accumulating evidence shows that several CVD forms are characterized by significant microcirculatory dysfunction, which may both cause and be caused by macrovascular disease, often preceding clinical manifestations by several years. Therefore, interest in exploring food supplements to prevent and restore microcirculation has grown. Given the continuous need to expand the available therapeutic arsenal for CVD, the food supplements market has recently grown and is expected to continue growing. (2) Methods: We provide an authoritative up-to-date comprehensive review of the impact of food supplementation on microcirculation by analyzing the European and American legal food supplements framework and the importance of food safety/food quality in this industry. We review the main literature about food bioactive compounds with a focus on microcirculation and some main food supplements with proven benefits. (3) Results: Despite a lack of scientific evidence, diet and microcirculatory function are clearly connected. The main food supplement examples in the literature with potential beneficial effects on microcirculation are: Ruscus aculeatus L., Centella asiatica L., Ginkgo biloba L., Salvia miltiorrhiza Bunge, Crataegus spp., Ginseng, Mangifera indica L., Aesculus hippocastanum L., Hamamelis virginiana L., and Vitis vinifera L. (4) Conclusions: Further clinical trials are necessary to better explore the effects of these food supplements.

Abstract
Ginseng is one of the oldest documented herbs still in use today. It is known as a panacea for many disease states and for the enhancement of wellness affecting most body systems. Very few side effects are experienced, but there are considerations with its use. Three major types of ginseng are described. Asian ginseng is more potent than American ginseng; however, most supplements come from American and Asian types of ginseng. Purchases should be made from reputable sources owing to the lack of standardization of the production of herbal supplements.

Ginsenosides for cardiovascular diseases; update on pre-clinical and clinical evidence, pharmacological effects and the mechanisms of action. Pharmacol Res 2021; 166:105481. [PMID: 33549726 DOI: 10.1016/j.phrs.2021.105481] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 01/20/2021] [Accepted: 02/02/2021] [Indexed: 12/14/2022]
Abstract
Cardiovascular disease (CVD) remains the major cause of death worldwide, accounting for almost 31% of the global mortality annually. Several preclinical studies have indicated that ginseng and the major bioactive ingredient (ginsenosides) can modulate several CVDs through diverse mechanisms. However, there is paucity in the translation of such experiments into clinical arena for cardiovascular ailments due to lack of conclusive specific pathways through which these activities are initiated and lack of larger, long-term well-structured clinical trials. Therefore, this review elaborates on current pharmacological effects of ginseng and ginsenosides in the cardiovascular system and provides some insights into the safety, toxicity, and synergistic effects in human trials. The review concludes that before ginseng, ginsenosides and their preparations could be utilized in the clinical treatment of CVDs, there should be more preclinical studies in larger animals (like the guinea pig, rabbit, dog, and monkey) to find the specific dosages, address the toxicity, safety and synergistic effects with other conventional drugs. This could lead to the initiation of large-scale, long-term well-structured randomized, and placebo-controlled clinical trials to test whether treatment is effective for a longer period and test the efficacy against other conventional therapies.

Abstract
AIMS To present an updated overview on the safety of concurrent use of food, herbal or dietary supplement and warfarin. METHODS A systematic literature review was performed on 5 databases from inception up to 31 December 2019. These interactions were classified depending on the likelihood of interaction and supporting evidences. RESULTS A total of 149 articles describing 78 herbs, food or dietary supplements were reported to interact with warfarin. These reports described potentiation with 45 (57.7%) herbs, food or dietary supplements while 23 (29.5%) reported inhibition and 10 (12.8%) reported limited impact on warfarin pharmacokinetics and pharmacodynamics. Twenty unique herb and dietary supplements also reported to result in minor bleeding events, such as purpura and gum bleeding as well as major events such as intracranial bleeding that led to death. CONCLUSION While most food, herbs and supplements can be safely taken in moderation, healthcare professionals should be aware of the increased risk of bleeding when taking several food and herbs. These include Chinese wolfberry, chamomile tea, cannabis, cranberry, chitosan, green tea, Ginkgo biloba, ginger, spinach, St. John's Wort, sushi and smoking tobacco. Patients should be counselled to continue to seek advice from their healthcare professionals when starting any new herbs, food or supplement.

Abstract
BACKGROUND The aim of the review was to assess whether ginseng can be a useful supplementation for seasonal acute upper respiratory infections (SAURIs). METHODS All clinical studies investigating ginseng efficacy for the treatment or prevention of SAURIs were included in the review. Medline, EMBASE, Web of Science, Scopus, Cochrane Library, Google Scholar were systematically screened for relevant articles up to May 26th, 2020. The risk of bias was assessed with the Cochrane tool (RoB 2). RESULTS Nine articles (describing ten trials about P. ginseng or P. quinquefolius) were included in the review. Evidence globally indicated some useful activity of intervention when administered in adjunct to influenza vaccination. The results of our quantitative synthesis suggested a significant effect on SAURIs incidence (RR = 0.69 [95 % C.I. 0.52 to 0.90], p < 0.05), as well as a significant reduction of their duration if only studies with healthy individuals were included in the analysis (MD=-3.11 [95 % C.I.-5.81 to -0.40], p < 0.05). However, the risk of bias was high-to-unclear for most included trials, and publication bias couldn't be excluded. DISCUSSION Limitations of existing evidence don't allow to draw conclusions on the topic. Nevertheless, it is not excluded that ginseng supplementation in adjunct to influenza vaccination and standard care might be useful for SAURIs prevention and management in healthy adult subjects, but further high-quality trials are needed to support this hypothesis. OTHER This research was not funded. The protocol was registered in PROSPERO under the following code: CRD42020156235.

Abstract
Thrombosis initiated by abnormal platelet aggregation is a pivotal pathological event that precedes most cases of cardiovascular diseases (CVD). Recently, growing evidence indicates that platelet could be a potential target for CVD prevention. However, as the conventional antithrombotic management strategy, applications of current antiplatelet agents are somewhat limited by their various side effects, such as bleeding risk and drug resistance. Hence, efforts have been made to search for agents as complementary therapies. Ginsenoside, the principal active component extracted from Panax ginseng, has gained much attention for its regulations on multiple crucial events of platelet aggregation. From structural characteristics to clinical applications, this review anatomized the intrinsic structure-function relationship of antiplatelet potency of ginsenosides, and the involved signal pathways were specifically summarized. Additionally, the emphasis was placed on clinical studies that investigate the antithrombotic efficacy of ginsenosides in the treatment of CVD. Further, a broad overview of approaches for improving the bioavailability of ginsenosides was concluded. Limitations and prospects of current studies were also discussed. This study may provide some new insights into the systematic understanding of ginsenosides in CVD treatment and lay a foundation for future research.

Abstract
Warfarin and ginseng have been widely used in the treatment of cardiovascular diseases. However, the clinical safety and effectiveness of herb-drug combination treatment are still controversial. Therefore, it is very essential to probe the interaction between warfarin and ginseng. In this study, in vitro and in vivo study was carried out to demonstrate that whether there is an interaction between warfarin and ginsenosides (GS), which is the main component of ginseng. In vitro study showed that the adhesion ability between endothelial cells and matrigel/platelets was enhanced due to the up-regulating expression of intercellular adhesion molecule (ICAM-1) and vascular cell adhesion molecule (VCAM-1) proteins by treatment of warfarin+GS combination compared to warfarin/GS treatment alone. Moreover, GS could weaken the anticoagulation effect of warfarin in hyperlipemia rats owning to the increased expression levels of coagulation factors and hepatic cytochrome P450 enzymes in plasma after long-term co-administration of warfarin with GS. The results of both in vitro and in vivo study demonstrated that there is a serious interaction between warfarin and ginseng, which may deteriorate atherosclerosis and thrombosis after combined use of warfarin and GS.

[PMID: 31453781 DOI: 10.2174/1389200220666190827160212] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 06/25/2019] [Accepted: 08/06/2019] [Indexed: 02/02/2023]
Abstract
Background:
Traditional Chinese medicine (TCM) has been used for medical purposes since the ancient
time and has gradually gained recognition worldwide. Nowadays, patients with thrombus presiding to anticoagulant/
antiplatelet drugs prefer taking TCM. However, an increasing number of studies on herb–drug interactions have
been shown. Nevertheless, findings are frequently conflicting and vague. In this review, we discuss the herb–drug
interactions between TCM and anticoagulant/antiplatelet drugs to provide guidance on concomitant ingestion with
anticoagulant/antiplatelet drugs.
Methods:
We undertook a structured search of medicine and drug databases for peer-reviewed literature using focused
review questions.
Results:
Danshen, Ginkgo, Ginger, H. Perforatum, SMY and Puerarin injection had directional regulation effects on
the efficacy of anticoagulant drugs by altering the CYPs, pharmacokinetic indexs and hemorheological parameters.
H. Perforatum inhibited the efficacy of Clopidogrel by enhancing the CYP3A4 activity and Ginkgo increased the
efficacy of Ticlopidine. Additionally, Renshen, the formulae except SMY and injections except Puerarin injection
could increase or decrease the efficacy of anticoagulant/antiplatelet drugs via regulating the CYPs, platelet aggregation,
hemorheological parameters and others.
Conclusion:
Some cases have reported that TCMs may increase the bleeding risk or has no effect on coagulation
when anticoagulant/antiplatelet drugs are concurrently used. However, pharmacokinetic studies have presented either
consistent or slightly varying results. So it is difficult to ascertain whether the concurrent use of TCM may increase
or reduce the pharmacologic effects of anticoagulant/antiplatelet drugs with adverse reactions. Therefore, herb–drug
interactions of TCM and anticoagulant/antiplatelet drugs should be further explored and defined.

Abstract
Herbal medicine, including traditional Chinese medicine (TCM), is widely used worldwide. Herbs and TCM formulas contain numerous active molecules. Basically, they are a kind of cocktail therapy. Herb-drug, herb-food, herb-herb, herb-microbiome, and herb-disease interactions are complex. There is potential for both benefit and harm, so only after understanding more of their mechanisms and clinical effects can herbal medicine and TCM be helpful to users. Many pharmacologic studies have been performed to unravel the molecular mechanisms; however, basic and clinical studies of good validity are still not enough to translate experimental results into clinical understanding and to provide tough evidence for better use of herbal medicines. There are still issues regarding the conflicting pharmacologic effects, pharmacokinetics, drug interactions, adverse and clinical effects of herbal medicine and TCM. Understanding study validation, pharmacologic effects, drug interactions, indications and clinical effects, adverse effects and limitations, can all help clinicians in providing adequate suggestions to patients. At present, it would be better to use herbs and TCM formulas according to their traditional indications matching the disease pathophysiology and their molecular mechanisms. To unravel the molecular mechanisms and understand the benefits and harms of herbal medicine and TCM, there is still much work to be done.

Abstract
Ginseng is the most frequently used herbal medicine for immune system stimulation and as an adjuvant with prescribed drugs owing to its numerous pharmacologic activities. It is important to investigate the beneficial effects and interaction of ginseng with therapeutic drugs. This review comprehensively discusses drug metabolizing enzyme- and transporter-mediated ginseng-drug interaction by analyzing in vitro and clinical results with a focus on ginsenoside, a pharmacologically active marker of ginseng. Impact of ginseng therapy or ginseng combination therapy on diabetic patients and of ginseng interaction with antiplatelets and anticoagulants were evaluated based on ginseng origin and ginsenoside content. Daily administration of Korean red ginseng (0.5-3 g extract; dried ginseng > 60%) did not cause significant herb-drug interaction with drug metabolizing enzymes and transporters. Among various therapeutic drugs administered in combination with ginseng, adjuvant chemotherapy, comprising ginseng (1-3 g extract) and anticancer drugs, was effective for reducing cancer-related fatigue and improving the quality of life and emotional scores. Limited information regarding ginsenoside content in each ginseng product and plasma ginsenoside concentration among patients necessitates standardization of ginseng product and establishment of pharmacokinetic-pharmacodynamic correlation to further understand beneficial effects of ginseng-therapeutic drug interactions in future clinical studies.

Abstract
Traditional Chinese medicine (TCM)-based herbal therapies have gained increasing popularity worldwide, raising concerns of its efficacy, safety profile and potential interactions with Western medications. Antithrombotic agents are among the most common prescription drugs involved in herb-drug interactions, and this article focused on aspirin, one of the most widely used antiplatelet agents worldwide. We discussed herbs that have potential interactions by exploring Western and TCM approaches to thrombotic events. Common TCM indications for these herbs were also highlighted, including possible scenarios of their concurrent usage with aspirin. With greater awareness and understanding of potential herb-drug interactions, TCM and Western physicians may collaborate more closely to identify, treat and, most importantly, prevent adverse drug events.

Abstract
Radiotherapy frequently induces failure of hematopoietic system and leads to myelosuppression. The objective of this study was to investigate the protective effect of dammarane sapogenins (DS), the hydrolysed product of the constituent ginsenosides of Panax ginseng, which are produced by gut metabolism, on radiation-induced hematopoietic injury. Mice were exposed to 3.5 Gy 60 Co γ-rays of total body radiation at a dose rate of 1.60 Gy per minute and treated with DS or granulocyte colony-stimulating factor immediately after radiation. The general condition of the mice, the peripheral blood cell counts, multiple colony forming unit (CFU) assays of hematopoietic progenitor cells, hematopoietic stem cell counts, bone marrow histology, and spleen colony forming unit counts were then investigated. Our results indicated that administration with DS could ameliorate 60 Co-irradiation induced damage and significantly increase the number of peripheral blood cells (white blood cells and platelets), 5 types of hematopoietic progenitor cells CFU (CFU-GM, CFU-E, BFU-E, CFU-Meg, and CFU-GEMM), hematopoietic stem cell (Lin- c-kit+ Scal-1+ ) numbers, and CFUs in the spleen, as well as improved bone marrow histopathology. All together, these results confirmed the enhancement of DS on hematopoiesis.

Abstract
Heart failure is a major medical and economic burden throughout the world. Although various treatment options are available to treat heart failure, death rates in both men and women remain high. Potential adjunctive therapies may lie with use of herbal medications, many of which possess potent pharmacological properties. Among the most widely studied is ginseng, a member of the genus Panax that is grown in many parts of the world and that has been used as a medical treatment for a variety of conditions for thousands of years, particularly in Asian societies. There are a number of ginseng species, each possessing distinct pharmacological effects due primarily to differences in their bioactive components including saponin ginsenosides and polysaccharides. While experimental evidence for salutary effects of ginseng on heart failure is robust, clinical evidence is less so, primarily due to a paucity of large-scale well-controlled clinical trials. However, there is evidence from small trials that ginseng-containing Chinese medications such as Shenmai can offer benefit when administered as adjunctive therapy to heart failure patients. Substantial additional studies are required, particularly in the clinical arena, to provide evidence for a favourable effect of ginseng in heart failure patients.

Abstract
Recent global deregulation of ginseng as the table food raises our concern about the possible ginseng-warfarin interaction that could be life-threatening to patients who take warfarin for preventing fatal strokes and thromboembolism while using ginseng products for bioenergy recovery. Here we show that quality-control ginsenosides, extracted from ginseng and containing its major active ingredients, produce dose- and time-dependent antagonism in rats against warfarin's anti-coagulation assessed by INR and rat thrombosis model. The interactions between ginsenosides and warfarin on thrombosis, pharmacokinetics, activities of coagulation factors and liver cytochrome P450 isomers are determined by using thrombosis analyzer, UPLC/MS/MS, ELISA and real-time PCR, respectively. The antagonism correlates well with the related pharmacokinetic interaction showing that the blood plateaus of warfarin reached by one-week warfarin administration are significantly reduced after three-week co-administration of warfarin with ginsenosides while 7-hydroxywarfarin is increased. The one-week warfarin and three-week warfarin-ginsenosides regimen result in restoring the suppressed levels by warfarin of the coagulating factors II, VII and protein Z, and significantly enhance activities of P450 3A4 and 2C9 that metabolize warfarin. The present study, for the first time, provides the solid evidence to demonstrate the warfarin-ginsenoside interaction, and warns the warfarin users and regulation authorities of the dangerous interaction.

Therapeutic Risk and Benefits of Concomitantly Using Herbal Medicines and Conventional Medicines: From the Perspectives of Evidence Based on Randomized Controlled Trials and Clinical Risk Management. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:9296404.

Abstract
Despite increased awareness of the potential of herb-drug interactions (HDIs), the lack of rigorous clinical evidence regarding the significance provides a challenge for clinicians and consumers to make rational decisions about the safe combination of herbal and conventional medicines. This review addressed HDIs based on evidence from randomized controlled trials (RCTs). Literature was identified by performing a PubMed search till January 2017. Risk description and clinical risk management were described. Among 74 finally included RCTs, 17 RCTs (22.97%) simply addressed pharmacodynamic HDIs. Fifty-seven RCTs (77.03%) investigated pharmacokinetic HDIs and twenty-eight of them showed potential or actual clinical relevance. The extent of an HDI may be associated with the factors such as pharmacogenomics, dose of active ingredients in herbs, time course of interaction, characteristics of the object drugs (e.g., administration routes and pharmacokinetic profiles), modification of herbal prescription compositions, and coexistence of inducers and inhibitors. Clinical professionals should enhance risk management on HDIs such as increasing awareness of potential changes in therapeutic risk and benefits, inquiring patients about all currently used conventional medicines and herbal medicines and supplements, automatically detecting highly substantial significant HDI by computerized reminder system, selecting the alternatives, adjusting dose, reviewing the appropriateness of physician orders, educating patients to monitor for drug-interaction symptoms, and paying attention to follow-up visit and consultation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chuanxiong Rhizoma (rhizomes of Ligusticum chuanxiong Hort), known as Chuanxiong in Chinese, has been used for treating cardiovascular diseases for centuries. Chuanxiong is a classical activating blood circulation herb in the treatment of thromboembolism heart diseases. Warfarin often combines with herbal prescriptions containing Chuanxiong in China. AIM OF THE STUDY The herb-drug interaction involving enterohepatic circulation process remains unclear. This study aimed to elucidate the effects of Chuanxiong Rhizoma on the pharmacokinetics of warfarin in rats after biliary drainage. MATERIALS AND METHODS Thirty-two rats were randomly divided into four groups: WN (healthy rats after the gastric-administration of 0.5mg/kg warfarin sodium), WO (a rat model of biliary drainage after the gastric-administration of 0.5mg/kg warfarin sodium), WCN (healthy rats after the gastric-administration of 0.5mg/kg warfarin sodium and 10g/kg Chuanxiong decoction), and WCO (a rat model of biliary drainage after the gastric-administration of 0.5mg/kg warfarin sodium and 10g/kg Chuanxiong decoction). The levels of warfarin and internal standard were quantified by LC-MS/MS. Comparisons between groups were performed according to the main pharmacokinetic parameters calculated by the DAS 2.1.1 software. RESULTS The established LC-MS/MS method was specific, precise and rapid. The pharmacokinetic parameters showed a significant difference between the WN and WO groups. There were significant differences in the area under the curve (AUC0-t), peak concentration (Cmax), total plasma clearance (CLz/F) and mean residence time (MRT0-t) between the WCO and WCN groups; the AUC0-t of warfarin in the WCN group was 2.42 times than that of the WN group (p<0.01); the WCO group displayed a decreased to 61.6% in the Cmax compared the WO group (p<0.01). CONCLUSION Biliary drainage significantly influenced the disposition of warfarin, and Chuanxiong significantly affected the warfarin disposition in rat plasma.

Abstract
The effectiveness of warfarin, an oral anticoagulant originally derived from a plant, is strongly affected by patient's characteristics such as the age, presence of comorbidities, and concomitant use of another drug. Warfarin has the potential to interact with many drugs, medicinal plants, and food, which increases the risk of adverse events. A critical analysis of scientific literature was conducted to assess the interferences of medicinal plants with blood haemostasis and then with warfarin anticoagulation. We found 58 different plants that may alter the blood haemostasis and anticoagulation with warfarin. The herbs that showed the greatest potential to interact with warfarin include garlic, ginger, ginkgo, St. John's wort, and ginseng, i.e. plants normally consumed as food and also used for therapeutic purposes. The interactions between drugs and herbs are varied because of the complex chemical matrix of plants. Mainly coumarins, quinones, xanthones, terpenes, lignans, and vitamin K showed significant influence on warfarin treatment. In general, these plants can potentiate the effect of warfarin by stimulating anticoagulation in multiple ways, and the clinical outcome associated with this interaction is the increase of bleeding risk. Moreover, potential interactions between herbal products and drugs are a safety concern, especially for drugs with a narrow therapeutic index or for patients receiving drug treatment for chronic diseases, and both of these apply to warfarin pharmacotherapy. Therefore, this review article summarises the data on the influence of medicinal plants on warfarin treatment and analyses this information in view of the interaction targets. The relevant plants were categorised according to their target, and their effects are discussed in order to organise the isolated information and to highlight the need of further discussion and new studies on the safety of herbal medicines and warfarin.

Abstract
Cancer is one of the leading causes of death worldwide. Ginseng, a key ingredient in traditional Chinese medicine, shows great promise as a new treatment option. As listed by the U.S. National Institutes of Health as a complementary and alternative medicine, its anti-cancer functions are being increasingly recognized. This review covers the mechanisms of action of ginsenosides and their metabolites, which can modulate signaling pathways associated with inflammation, oxidative stress, angiogenesis, metastasis, and stem/progenitor-like properties of cancer cells. The emerging use of structurally modified ginsenosides and recent clinical studies on the use of ginseng either alone or in combination with other herbs or Western medicines which are exploited as novel therapeutic strategies will also be explored.

Safety Analysis of Panax Ginseng in Randomized Clinical Trials: A Systematic Review. MEDICINES 2015; 2:106-126. [PMID: 28930204 PMCID: PMC5533164 DOI: 10.3390/medicines2020106] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/16/2015] [Revised: 05/28/2015] [Accepted: 05/29/2015] [Indexed: 12/01/2022]
Abstract
Background:Panax ginseng C.A. Meyer is one of the most frequently used herbs in the world. The roots of Panax ginseng have been used as a traditional tonic and medicine for thousands of years in Korea and China. Today, ginseng root is used as a dietary supplement and complementary medicine and for adjuvant therapeutics worldwide. The efficacy of ginseng has been studied in a wide range of basic research and clinical studies. However, it has been reported that the results from clinical studies are conflicting, and they depend on the parameters of the protocol design including the conditions of the participants and the types of ginseng used such as red ginseng, white ginseng, fermented ginseng and cultured ginseng. Meanwhile, in addition to clinical efficacy, the safety of ginseng is a highly important matter for customers. With globally increasing demand for Panax ginseng as a dietary supplement or complementary medicine, it is necessary to provide information on its safe use to customers to improve their health conditions. Although the safety of Panax ginseng in pre-clinical studies is well known, the evaluation of safety in clinical studies has so far been insufficient. This systematic review was conducted to assess the safety of ginseng in randomized controlled clinical trials (RCT) over the last 10 years. We chose the last 10 years because many clinical trials have been conducted in the past 10 years, and it will help to understand the recent trends in RCTs of ginseng. Methods: Articles on ginseng studies were searched with keywords in MEDLINE and four other Korean online database sites. Studies with ginseng as a monopreparation were selected while studies with single administration, preparations combined with other herbs or drug combinations were excluded from the selected studies. Data from the selected studies meeting the criteria were extracted and reviewed in terms of study design, condition and number of participants, type of ginseng, dosage, duration, main results, adverse events and adverse reactions. Results: Forty-four studies met the selection criteria. These studies covered the efficacy of ginseng in areas such as cardiovascular function, glucose metabolism, sexual function, anti-oxidation, anti-fatigue and psychomotor function. Twenty-nine studies showed positive results while fifteen studies showed no effect. Sixteen studies reported adverse events while five studies had no adverse events. Twenty-three studies did not mention any adverse events. The main adverse events of ginseng reported were general symptoms such as hot flushes, insomnia and dyspepsia with no significant difference in frequency and symptoms between the ginseng and placebo groups. The symptoms were mild and temporary with no serious or severe adverse events. Conclusion:Panax ginseng showed a very safe profile in a limited number of RCTs with a small number of participants with various conditions ranging from healthy participants to patients with symptoms. However, to increase the usefulness and lower the health risk of Panax ginseng to customers, clinical trials on a larger scale and with a higher standard are necessary to define its efficacy and safety as a dietary supplement or complementary medicine.

Do herbal formulas influence the international normalized ratio of patients taking warfarin? A retrospective study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:213927.

Abstract
Warfarin is a common anticoagulant agent for cardiovascular diseases, and it is known to interact with several foods and drugs. Several studies report an interaction between warfarin and herbal medicines; however, the influence of herbal medicines on the international normalized ratio (INR) is still controversial. We investigated the influence of herbal formulas on INR of patients taking warfarin. We searched electronic medical records of inpatients for INR results. Then, we compared the changes in INR and any adverse events between the group taking herbal formulas and warfarin (herbal group) and another group taking warfarin only (nonherbal group). Eighty-six patients were included; 45 patients were assigned to the herbal group and 41 patients to the nonherbal group. The herbal group had taken the same dose of warfarin for a longer period. The nonherbal group had a slightly higher mean INR value than the herbal group. The ratio of INR less than 2 and greater than 3, the ratio of INR that increased or decreased by one or more compared to the initial INR, and the ratio of adverse events were not significantly different between the two groups. It is suggested that use of herbal formulas may not influence INR value.

Abstract
BACKGROUND Most ischaemic strokes are caused by a blood clot blocking an artery in the brain. Clot prevention with anticoagulants might improve outcomes if bleeding risks are low. This is an update of a Cochrane review first published in 1995, with recent updates in 2004 and 2008. OBJECTIVES To assess the effectiveness and safety of early anticoagulation (within the first 14 days of onset) in people with acute presumed or confirmed ischaemic stroke. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (June 2014), the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Database of Systematic Reviews (CDSR), the Database of Reviews of Effects (DARE) and the Health Technology Assessment Database (HTA) (The Cochrane Library 2014 Issue 6), MEDLINE (2008 to June 2014) and EMBASE (2008 to June 2014). In addition, we searched ongoing trials registries and reference lists of relevant papers. For previous versions of this review, we searched the register of the Antithrombotic Trialists' (ATT) Collaboration, consulted MedStrategy (1995), and contacted relevant drug companies. SELECTION CRITERIA Randomised trials comparing early anticoagulant therapy (started within two weeks of stroke onset) with control in people with acute presumed or confirmed ischaemic stroke. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials for inclusion, assessed trial quality, and extracted the data. MAIN RESULTS We included 24 trials involving 23,748 participants. The quality of the trials varied considerably. The anticoagulants tested were standard unfractionated heparin, low-molecular-weight heparins, heparinoids, oral anticoagulants, and thrombin inhibitors. Over 90% of the evidence relates to the effects of anticoagulant therapy initiated within the first 48 hours of onset. Based on 11 trials (22,776 participants) there was no evidence that anticoagulant therapy started within the first 14 days of stroke onset reduced the odds of death from all causes (odds ratio (OR) 1.05; 95% confidence interval (CI) 0.98 to 1.12) at the end of follow-up. Similarly, based on eight trials (22,125 participants), there was no evidence that early anticoagulation reduced the odds of being dead or dependent at the end of follow-up (OR 0.99; 95% CI 0.93 to 1.04). Although early anticoagulant therapy was associated with fewer recurrent ischaemic strokes (OR 0.76; 95% CI 0.65 to 0.88), it was also associated with an increase in symptomatic intracranial haemorrhages (OR 2.55; 95% CI 1.95 to 3.33). Similarly, early anticoagulation reduced the frequency of symptomatic pulmonary emboli (OR 0.60; 95% CI 0.44 to 0.81), but this benefit was offset by an increase in extracranial haemorrhages (OR 2.99; 95% CI 2.24 to 3.99). AUTHORS' CONCLUSIONS Since the last version of the review, no new relevant studies have been published and so there is no additional information to change the conclusions. Early anticoagulant therapy is not associated with net short- or long-term benefit in people with acute ischaemic stroke. Treatment with anticoagulants reduced recurrent stroke, deep vein thrombosis and pulmonary embolism, but increased bleeding risk. The data do not support the routine use of any of the currently available anticoagulants in acute ischaemic stroke.

Abstract
In traditional Chinese medicine (TCM), the human body is divided into Yin and Yang. Diseases occur when the Yin and Yang balance is disrupted. Different herbs are used to restore this balance, achieving the goal of treatment. However, inherent difficulties in designing experimental trials have left much of TCM yet to be substantiated by science. Despite that, TCM not only remains a popular form of medical treatment among the Chinese, but is also gaining popularity in the West. This phenomenon has brought along with it increasing reports on herb-drug interactions, beckoning the attention of Western physicians, who will find it increasingly difficult to ignore the impact of TCM on Western therapies. This paper aims to facilitate the education of Western physicians on common Chinese herbs and raise awareness about potential interactions between these herbs and warfarin, a drug that is especially susceptible to herb-drug interactions due to its narrow therapeutic range.

Abstract
Ginseng has long been used as a functional food or therapeutic supplement and it is empirically known to be safe and nontoxic. During recent decades, a number of in vitro and in vivo experiments, as well as human studies have been conducted to prove the safety of various types of ginseng samples and their components. Clinical trials, case reports, and in vitro and in vivo research articles addressing the safety, toxicity, and other adverse events of ginseng application were selected and reviewed. Patient risks associated with ginseng abuse and misuse such as affective disorder, allergy, cardiovascular and renal toxicity, genital organ bleeding, gynecomastia, hepatotoxicity, hypertension, reproductive toxicity, and anticoagulant-ginseng interaction were reviewed and summarized. There are some cases of patient risk associated with ginseng abuse and misuse depending on patients' conditions although further investigation in more cases is required to clarify these issues.

Abstract
Recognition of the adverse effects of medicinal herbs is not routine and the reports on such effects are even less frequent in clinical practice. Potential herb-drug interactions are of a major safety concern, especially for drugs with narrow therapeutic indices like warfarin, which can lead to severe adverse reactions that are sometimes life-threatening. The interactions between warfarin and medicinal herbs described in the literature have been summarized in this paper relying on Medline database (via PubMed) using the key words: warfarin, herbal supplements and interactions. The references on the analyzed literature have been investigated in order to collect the existing data. The case reports with severe adverse effects such as spontaneous postoperative bleeding, formation of hematomas, hematemesis, melena, thrombosis, subarachnoid hemorrhage and/or subdural hematomas after concomitant use of warfarin and the medicinal herbs: Panax ginseng, Hypericum perforatum, Salvia milthiorizza, Gingko biloba, Serenoa repens, Angelica sinensis, Vaccinium species, Allium sativum, Zingiber officinale, Tanacetum parthenium, Lucium barbarum, Matricaria chamomilla, Boswellia serrata and Camellia sinensis have been estimated. Some of the interactions between warfarin and medicinal herbs have been well assessed proving that they are closely-dependent. The interactions between warfarin and medicinal herbs, not generally reported in previous reviews, are presented in our review. The health professionals who are involved in treating the patients are expected to be fully informed about the interactions between warfarin and medicinal herbs in order to minimize the health risks of the patients.

Abstract
Hyperlipidemia, characterized by the abnormal blood lipid profiles, is one of the dominant factors of many chronic diseases such as diabetes, obesity, and cardiovascular diseases (CVD). For the low cost, effectiveness, and fewer side effects, the popularity of using traditional Chinese medicine (TCM) to handle hyperlipidemia is increasing and its role in health care has been recognized by the public at large. Despite the importance of TCM herbs and formulations, there is no comprehensive review summarizing their scientific findings on handling hyperlipidemia. This review summarizes the recent experimental and clinical results of nine representative single Chinese herbs and seven classic TCM formulae that could improve lipid profiles so as to help understand and compare their underlying mechanisms. Most of single herbs and formulae demonstrated the improvement of hyperlipidemic conditions with multiple and diverse mechanisms of actions similar to conventional Western drugs in spite of their mild side effects. Due to increasing popularity of TCM, more extensive, well-designed preclinical and clinical trials on the potential synergistic and adverse side effects of herb-drug interactions as well as their mechanisms are warranted. Hyperlipidemic patients should be warned about the potential risks of herb-drug interactions, particularly those taking anticoagulants and antiplatelet drugs.

Abstract
Globally, herbal medicines represent a $60 billion industry, and they account for approximately 20% of the overall drug market. Herbs (or herbals) that improve the taste of foods as flavor enhancement spices can generally be used safely by the CKD patient population. However, many herbals are sold as dietary supplements for medicinal use, and these are regulated as foods not drugs, thus allowing herbal supplements to be sold without premarket evaluation or approval by the Food and Drug Administration. In the absence of required testing, many herbal supplements are manufactured inconsistently with wide variations in composition. It is essential for the nephrology practitioner to assess CKD patients regarding their use of these products to understand their risks and benefits and to educate patients and families. This article will discuss some of the more commonly used products and their potential positive and adverse effects on CKD patients.

Abstract
Red ginseng (RG) is the top-selling functional food in Korea, but is not recommended for use in hypertensive patients. This study was performed to determine the pharmacokinetic (PK) interaction between RG and amlodipine, an antihypertensive drug. RG (0, 0.5, 1, or 2 g/kg/d) was administered orally for 2 wk, and then amlodipine (10 mg/kg) was given orally, to Sprague-Dawley (SD) rats. Blood was collected at 0.08, 0.25, 1, 1.5, 2, 3, 6, 12, and 24 h after amlodipine administration. In intravenous (iv) study, RG (0, 1, or 2 g/kg/d) was administered orally to SD rats for 2 wk, followed by amlodipine (2 mg/kg) intravenously (iv). Plasma concentrations of amlodipine were analyzed using a high-pressure liquid chromatography-tandem mass system (LC-MS/MS). Oral administration of amlodipine produced an increase of time to maximum plasma concentration (tmax: 2.6, 4.1, 8.3, and 8.9 h at 0, 0.5, 1, and 2 g/kg/d, respectively), and a decrease of maximum plasma concentration (Cmax: 278.5, 212.4, 232.1, and 238.7 ng/ml at 0, 0.5, 1, and 2 g/kg/d, respectively.). However, the area under the concentration-time curve from time 0 to 24 h measurable concentration (AUC0-24 h was 3487.4, 2895.4, 3158.2, and 3495 ng/h/ml at 0, 0.5, 1, and 2 g/kg/d respectively) was not significantly changed among the different dose groups. Administration of amlodipine iv produced no significant changes in the apparent terminal half-life, volume of distribution, and AUC0-24 hr among the different dose groups. These results suggest that RG induced negligible influence on amlodipine pharmacokinetically in rats.

Abstract
Panax ginseng is one of the most frequently used herbs in the world. Numerous trials have evaluated its clinical benefits. However, the quality of these studies has not been comprehensively and systematically assessed. We reviewed randomized controlled trials (RCTs) of Panax ginseng to evaluate their quality and risk of bias. We searched four English databases, without publication date restriction. Two reviewers extracted details about the studies' methodological quality, guided by the Consolidated Standards of Reporting Trials (CONSORT) checklist and its extension for herbal interventions. Risk of bias was determined using the Cochrane Risk of Bias tool. Of 475 potentially relevant studies, 58 met our inclusion criteria. In these 58 studies, 48.3% of the suggested CONSORT checklist items and 35.9% of the extended herbal items were reported. The quality of RCTs published after the CONSORT checklist improved. Until 1995 (before CONSORT) (n = 4), 32.8% of the items were reported in studies. From 1996-2006 (CONSORT published and revised) (n = 30), 46.1% were reported, and from 2007 (n = 24), 53.5% were reported (p = 0.005). After the CONSORT extension for herbal interventions was published in 2006, RCT quality also improved, although not significantly. Until 2005 (n = 34), 35.2% of the extended herbal items were reported in studies; and from 2006 onwards (n = 24), 37.3% were reported (p = 0.64). Most studies classified risk of bias as "unclear". Overall, the quality of Panax ginseng RCT methodology has improved since the CONSORT checklist was introduced. However, more can be done to improve the methodological quality of, and reporting in, RCTs.

Abstract
Sexual health or erectile dysfunction (ED) state of the art guidelines provide a thorough overview of conventional prescription or other notable extrinsic treatment options. Yet, over the past 10-15 years, a plethora of international researchers have established that individual and comprehensive lifestyle changes can prevent and potentially improve ED. We review the lifestyle evidence that should equate to grade A or level 1 evidence recommendations for ED. We also review the evidence for Panax ginseng, an over-the-counter (OTC) dietary supplement with a 35-year history of laboratory investigations, multiple positive randomized trials over approximately 15 years and several independent meta-analyses and systematic reviews. Perhaps it is time to at least discuss and even emphasize lifestyle and other non-conventional interventions in ED guidelines so that patients can explore a diversity of potentially synergistic choices with their physicians and can improve their quality and quantity of life. Ignoring the consistent, positive data on lifestyle modifications in ED guidelines, for example, is tantamount to ignoring diet and lifestyle changes to reduce the risk of or ameliorate cardiovascular diseases.

Abstract
Panax ginseng C.A. Meyer is a common herb with many purported health benefits. However, there is no conclusive evidence supporting its use in the treatment of any particular disease. We conducted a systematic review to evaluate randomised controlled trials. Four English databases were searched with no publication date restriction. Included studies evaluated P. ginseng in patients with any type of disease or in healthy individuals. We assessed the quality of studies using the Cochrane risk of bias tool. Of the 475 potentially relevant studies, 65 met the inclusion criteria. These studies examined P. ginseng's effects on psychomotor performance (17 studies), physical performance (ten), circulatory system (eight), glucose metabolism (six), the respiratory system (five), erectile dysfunction (four), immunomodulation (four), quality of life/mood (four), antioxidant function (two), cancer (two), menopausal symptoms (two) and dry mouth (one). The risk of bias was unclear in most studies. Authors evaluated adverse events in 40 studies, with 135 minor events and no serious adverse events reported. P. ginseng shows promising results for improving glucose metabolism and moderating the immune response. This may have implications for several diseases including type 2 diabetes and chronic respiratory conditions. Further studies are needed to explore P. ginseng's potential as an effective treatment for these and other health conditions.

Abstract
Ginseng is an herbal medicine used worldwide. It is reported to have a wide range of pharmacological activities because of a diversified group of steroidal saponins called ginsenosides. Compared to extensive pharmacological studies of ginseng, the pharmacokinetics, especially the metabolism of this herb, has received less attention. In this article we review the known pharmacokinetic data on ginseng. Understanding ginseng's pharmacokinetics may reduce the potential for interactions in patients who use both ginseng and prescription medications. In addition, bioavailability after taking ginseng orally is low, and the metabolites of ginsenosides produced by gut microbiota may be biologically active. One ginseng metabolite, Compound K, and its potential for cancer chemoprevention is also discussed. An active ginseng metabolite may differ in distribution and clearance from its parent compound, and the parent compound and its metabolite may be bioactive by similar or different mechanisms. Thus, further investigation of ginseng metabolites is needed for predicting the therapeutic outcome with ginseng.

Interactions of commonly used dietary supplements with cardiovascular drugs: a systematic review. Syst Rev 2012; 1:26. [PMID: 22651380 PMCID: PMC3534595 DOI: 10.1186/2046-4053-1-26] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2011] [Accepted: 04/18/2012] [Indexed: 11/10/2022] Open
Abstract
UNLABELLED BACKGROUND The objective of this systematic review was to examine the benefits, harms and pharmacokinetic interactions arising from the co-administration of commonly used dietary supplements with cardiovascular drugs. Many patients on cardiovascular drugs take dietary supplements for presumed benefits and may be at risk for adverse supplement-drug interactions. METHODS The Allied and Complementary Medicine Database, the Cochrane Library, EMBASE, International Bibliographic Information on Dietary Supplements and MEDLINE were searched from the inception of the review to October 2011. Grey literature was also reviewed.Two reviewers independently screened records to identify studies comparing a supplement plus cardiovascular drug(s) with the drug(s) alone. Reviewers extracted data using standardized forms, assessed the study risk of bias, graded the strength of evidence and reported applicability. RESULTS Evidence was obtained from 65 randomized clinical trials, 2 controlled clinical trials and 1 observational study. With only a few small studies available per supplement, evidence was insufficient for all predefined gradable clinical efficacy and harms outcomes, such as mortality and serious adverse events. One long-term pragmatic trial showed no benefit from co-administering vitamin E with aspirin on a composite cardiovascular outcome. Evidence for most intermediate outcomes was insufficient or of low strength, suggesting no effect. Incremental benefits were noted for triglyceridemia with omega-3 fatty acid added to statins; and there was an improvement in levels of high-density lipoprotein cholesterol with garlic supplementation when people also consumed nitrates CONCLUSIONS Evidence of low-strength indicates benefits of omega-3 fatty acids (plus statin, or calcium channel blockers and antiplatelets) and garlic (plus nitrates or warfarin) on triglycerides and HDL-C, respectively. Safety concerns, however, persist.

Abstract
Although employed in Asian societies for thousands of years, the use of ginseng as an herbal medication for a variety of disorders has increased tremendously worldwide in recent years. Ginseng belongs to the genus Panax, of which there exists a variety, generally reflecting their geographic origin. North American ginseng (Panax quinquefolius) and Asian ginseng (Panax ginseng) are two such varieties possessing a plethora of pharmacological properties, which are attributed primarily to the presence of different ginsenosides that bestow these ginsengs with distinct pharmacodynamic profiles. The many cardiovascular benefits attributed to ginseng include cardioprotection, antihypertensive effects, and attenuation of myocardial hypertrophy and heart failure. Experimental studies have revealed a number of beneficial properties of ginseng, particularly in the area of cardiac protection, where ginseng and ginsenosides have been shown to protect the ischaemic and reperfused heart in a variety of experimental models. Emerging evidence also suggests that ginseng attenuates myocardial hypertrophy, thus blunting the remodelling and heart failure processes. However, clinical evidence of efficacy is not convincing, likely owing primarily to the paucity of well designed, randomized, controlled clinical trials. Adding to the complexity in understanding the cardiovascular effects of ginseng is the fact that each of the different ginseng varieties possesses distinct cardiovascular properties, as a result of their respective ginsenoside composition, rendering it difficult to assign a general, common cardiovascular effect to ginseng. Additional challenges include the identification of mechanisms (likely multifaceted) that account for the effects of ginseng and determining which ginsenoside(s) mediate these cardiovascular properties. These concerns notwithstanding, the potential cardiovascular benefit of ginseng is worthy of further studies in view of its possible development as a cardiovascular therapeutic agent, particularly as adjunctive therapy to existing medications.

Abstract
This article provides an overview of the clinical evidence of interactions between herbal and conventional medicines. Herbs involved in drug interactions--or that have been evaluated in pharmacokinetic trials--are discussed in this review. While many of the interactions reported are of limited clinical significance and many herbal products (e.g. black cohosh, saw palmetto, echinacea, hawthorn and valerian) seem to expose patients to minor risk under conventional pharmacotherapy, a few herbs, notably St. John's wort, may provoke adverse events sufficiently serious to endanger the patients' health. Healthcare professionals should remain vigilant for potential interactions between herbal medicines and prescribed drugs, especially when drugs with a narrow therapeutic index are used.

Abstract
This systematic review aims to evaluate the available evidence from randomized clinical trials of the clinical efficacy and safety of ginseng. Systematic literature searches were performed in 13 databases up to March 2009 without language restriction. All randomized clinical trials evaluating the clinical effects or safety of the use of ginseng monopreparations (Panax ginseng or P. quinquefolium) were considered for inclusion. A total of 411 potentially relevant studies were identified and 57 randomized clinical trials were included. The main indications included glucose metabolism, physical performance, psychomotor function, sexual function, cardiac function, pulmonary disease, and cerebrovascular disease. We found strong evidence of a positive effect of ginseng on glucose metabolism, psychomotor function, and pulmonary disease, whereas evidence suggests that ginseng is not effective at enhancing physical performance. However, ginseng generally has a good safety profile and the incidence of adverse effects seems to be low. In conclusion, our review compiles the evidence on the use of ginseng, finding a strong positive potential for glucose metabolism, psychomotor function, and pulmonary disease, but not for physical performance enhancement.

Abstract
OBJECTIVE To assess the extent of appropriate counseling provided to patients by pharmacists and nonpharmacists in retail settings regarding herbal dietary supplements for weight loss. DESIGN Descriptive, exploratory, nonexperimental study. SETTING Phoenix, AZ, metropolitan area, from June 2008 to January 2009. PARTICIPANTS Pharmacists and nonpharmacists (e.g., cashiers, sales clerks, pharmacy technicians) working in retail locations selling herbal dietary supplements (e.g., grocery stores, health food stores, pharmacies). INTERVENTION Investigators posing as patients sought herbal weight loss supplement product recommendations and counseling on potential safety, drug interaction, and adverse effect issues from pharmacists or nonpharmacists. MAIN OUTCOME MEASURES Level of knowledge regarding safety and efficacy of herbal dietary supplements for weight loss. RESULTS 52 sites were visited, and 27 unique product recommendations were given. In general, counseling provided to investigators/patients by pharmacists versus nonpharmacists varied significantly (P < 0.05) except when participants were asked about expected weight loss (P = 0.39) or use of herbal supplements during pregnancy (P = 0.07) and breast-feeding (P = 0.48). Pharmacists were more reluctant to recommend herbal products for weight loss than nonpharmacists and tended to question the safety and/or efficacy of these products or refer the patient to an alternate health care provider. CONCLUSION The counseling that investigators/patients received regarding herbal products for weight loss in various retail settings from both pharmacists and non-pharmacists varied greatly. Efforts are needed from the medical and herbal communities to ensure that patients are adequately informed about herbal products at the point of purchase.
