[PMID: 31418664 DOI: 10.2174/1570161117666190715121939] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 04/29/2019] [Accepted: 05/01/2019] [Indexed: 12/12/2022]
Abstract
Aging and aging-associated diseases are issues with unsatisfactory answers in the medical field. Aging causes important physical changes which, even in the absence of the usual risk factors, render the cardiovascular system prone to some diseases. Although aging cannot be prevented, slowing down the rate of aging is entirely possible to achieve. In some traditional medicine, medicinal herbs such as Ginseng, Radix Astragali, Ganoderma lucidum, Ginkgo biloba, and Gynostemma pentaphyllum are recognized by the "nourishing of life" and their role as anti-aging phytotherapeutics is increasingly gaining attention. By mainly employing PubMed here we identify and critically analysed 30 years of published studies focusing on the above herbs' active components against aging and aging-associated conditions. Although many plant-based compounds appear to exert an anti-aging effect, the most effective resulted in being flavonoids, terpenoids, saponins, and polysaccharides, which include astragaloside, ginkgolide, ginsenoside, and gypenoside specifically covered in this review. Their effects as antiaging factors, improvers of cognitive impairments, and reducers of cardiovascular risks are described, as well as the molecular mechanisms underlying the above-mentioned effects along with their potential safety. Telomere and telomerase, PPAR-α, GLUTs, FOXO1, caspase-3, bcl-2, along with SIRT1/AMPK, PI3K/Akt, NF-κB, and insulin/insulin-like growth factor-1 pathways appear to be their preferential targets. Moreover, their ability to work as antioxidants and to improve the resistance to DNA damage is also discussed. Although our literature review indicates that these traditional herbal medicines are safe, tolerable, and free of toxic effects, additional well-designed, large-scale randomized control trials need to be performed to evaluate short- and long-term effects and efficacy of these medicinal herbs.

Abstract
The Integrative Medicine Service at Memorial Sloan Kettering Cancer Center developed and maintains About Herbs (www.aboutherbs.com), which provides summaries of research data including purported uses, adverse effects, and herb-drug interactions for about 284 dietary supplements. Using Google Analytics, we found the website registered more than 26,317,000 hits since November 2002. The 10 most searched-for herbs/supplements of 2018 are chaga mushroom, turmeric, ashwagandha, reishi mushroom, graviola, Active Hexose-Correlated Compound, boswellia, dandelion, green tea, and Coriolus versicolor. Here we discuss their safety, herb-drug interactions, and appropriate uses in the oncology setting, based on literature searches in PubMed. Over the past 16 years, the evidence for use of these supplements is based mostly on preclinical findings, with few well-designed studies and limited trials conducted in cancer patients. It is important to familiarize health care professionals about popular supplements, so patients can be informed to make decisions that maximize benefits and minimize risks.

Abstract
Cardiovascular diseases (CVDs) are a significant health burden with an ever-increasing prevalence. They remain the leading causes of morbidity and mortality worldwide. The use of medicinal herbs continues to be an alternative treatment approach for several diseases including CVDs. Currently, there is an unprecedented drive for the use of herbal preparations in modern medicinal systems. This drive is powered by several aspects, prime among which are their cost-effective therapeutic promise compared to standard modern therapies and the general belief that they are safe. Nonetheless, the claimed safety of herbal preparations yet remains to be properly tested. Consequently, public awareness should be raised regarding medicinal herbs safety, toxicity, potentially life-threatening adverse effects, and possible herb–drug interactions. Over the years, laboratory data have shown that medicinal herbs may have therapeutic value in CVDs as they can interfere with several CVD risk factors. Accordingly, there have been many attempts to move studies on medicinal herbs from the bench to the bedside, in order to effectively employ herbs in CVD treatments. In this review, we introduce CVDs and their risk factors. Then we overview the use of herbs for disease treatment in general and CVDs in particular. Further, data on the ethnopharmacological therapeutic potentials and medicinal properties against CVDs of four widely used plants, namely Ginseng, Ginkgo biloba, Ganoderma lucidum, and Gynostemma pentaphyllum, are gathered and reviewed. In particular, the employment of these four plants in the context of CVDs, such as myocardial infarction, hypertension, peripheral vascular diseases, coronary heart disease, cardiomyopathies, and dyslipidemias has been reviewed, analyzed, and critically discussed. We also endeavor to document the recent studies aimed to dissect the cellular and molecular cardio-protective mechanisms of the four plants, using recently reported in vitro and in vivo studies. Finally, we reviewed and reported the results of the recent clinical trials that have been conducted using these four medicinal herbs with special emphasis on their efficacy, safety, and toxicity.

Abstract
Ginkgolides are the major active component of Ginkgo biloba for inhibition of platelet activating factor receptor. An azide-alkyne Huisgen cycloaddition reaction was used to introduce a triazole nucleus into the target ginkgolide molecules. A series of ginkgolide-1,2,3-triazole conjugates with varied functional groups including benzyl, phenyl and heterocycle moieties was thus synthesized. Many of the designed derivatives showed potent antiplatelet aggregation activities with IC50 values of 5~21 nM.

Abstract
Many older people who have emigrated from Vietnam to the United States continue to use the traditional medicines that they used in their country of origin. Clinicians trained in the West may not be familiar with these products. We reviewed 6 Asian traditional medicines that are popular among older Vietnamese people living in the United States. Each medicine has significant side effects that can lead to complications in patients undergoing surgery. Here, we present the case of a patient who used Cordyceps sinensis daily as a tonic and experienced prolonged bleeding after dental surgery.

Abstract
The prevalence of natural health product (NHP) use in Canada is extensive. Patients with chronic diseases, including diabetes, use NHPs at a higher rate than the general population. Many NHPs exert hypoglycemic effects, among other effects relevant to diabetes management. To provide a practical, clinical review of NHPs with such effects targeted to pharmacists, a literature search was performed to collect data on the efficacy and safety profiles of 10 commonly used NHPs that exert antidiabetic properties. The following NHPs are included in this clinical review: alpha-lipoic acid, chromium, magnesium, bitter melon, cinnamon, fenugreek, gymnema, milk thistle, Reishi mushroom and white mulberry. Given the potential of NHPs to additively cause hypoglycemia when used concurrently with conventional medications, pharmacists should be up to date with current evidence around NHPs that may affect diabetes care to prevent adverse reactions and interactions. In addition, effective and respectful communication with patients around NHP use and collaboration with various health-care providers are essential in the patient care process.

Abstract
BACKGROUND Ganoderma lucidum (also known as lingzhi or reishi) is a mushroom that has been consumed for its broad medicinal properties in Asia for over 2000 years. G lucidum is becoming increasingly popular in western countries as a complementary medicine for cardiovascular health. OBJECTIVES To evaluate the effectiveness of G lucidum for the treatment of pharmacologically modifiable risk factors of cardiovascular disease in adults. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL Issue 6 of 12, 2014) on The Cochrane Library, MEDLINE (OVID, 1946 to June week 3 2014), EMBASE (OVID, 1980 to 2014 week 26), Science Direct (1823 to 2013), Current Controlled Trials (1990 to 2013), Australian New Zealand Clinical Trials Registry (2005 to 2013), Chinese Biomedical Literature Database (2007 to 2013), Chinese Medical Current Contents (2007 to 2013) and other databases. We checked reference lists of included studies, contacted content experts and handsearched The International Journal of Medicinal Mushrooms. We applied no language or publication restrictions. SELECTION CRITERIA Randomised controlled trials and controlled clinical trials of G lucidum for the treatment of cardiovascular risk factors. Primary outcomes were blood glucose level, blood pressure and lipid profile. DATA COLLECTION AND ANALYSIS Two authors independently selected trials, assessed risk of bias and cross checked data extraction and analysis. A third author arbitrated in the event of disagreement. MAIN RESULTS Five trials with a total of 398 participants were eligible for inclusion. Of these, one study was published in Chinese and translated to English; one study was published but study authors provided the additional data used in this review; one study was unpublished and the study authors provided data; and two studies did not provide comparison group data suitable for statistical analyses. The three studies from which data were used for statistical analyses compared G lucidum (1.4 g to 3 g per day) to placebo over 12 to 16 weeks of intervention. Although inclusion criteria varied, all participants of these three studies had type 2 diabetes mellitus. Of the five included studies, risk of bias was low for one study and unclear for the remaining four.Results from two studies showed that G lucidum was not associated with statistically or clinically significant reduction in HbA1c (WMD -0.10%; 95% CI -1.05% to 0.85%; 130 participants), total cholesterol (WMD -0.07mmol/L; 95% CI -0.57 mmol/L to 0.42 mmol/L; 107 participants ), low-density lipoprotein cholesterol (WMD 0.02 mmol/L; 95% CI -0.41 mmol/L to 0.45 mmol/L; 107 participants), or body-mass index (WMD -0.32 kg/m(2); 95% CI -2.67 kg/m(2) to 2.03 kg/m(2;) 107 participants). All other analyses were from a single study of 84 participants. We found no improvement for fasting plasma glucose (WMD 0.30 mmol/L; 95% CI -0.95 mmol/L to 1.55 mmol/L). Measures of post-prandial blood glucose level found inconsistent results, being in favour of placebo for '2-hour post-prandial blood glucose' (WMD 0.7 mmol/L; 95% CI 0.29 mmol/L to 1.11 mmol/L) and in favour of G lucidum for 'plasma glucose under the curve at 4th hour' (WMD -49.4mg/dL/h; 95% CI -77.21 mg/dL/h to -21.59 mg/dL/h). As the Minimal Clinical Important Differences are unknown, the clinical significance of this effect is unclear. There were no statistically significant differences between groups for blood pressure or triglycerides. Participants who took G lucidum for four months were 1.67 times (RR 1.67 95% CI 0.86 to 3.24) more likely to experience an adverse event than those who took placebo but these were not serious side effects. AUTHORS' CONCLUSIONS Evidence from a small number of randomised controlled trials does not support the use of G lucidum for treatment of cardiovascular risk factors in people with type 2 diabetes mellitus. Future research into the efficacy of G lucidum should be placebo-controlled and adhere to clinical trial reporting standards.

Abstract
In this study, attempt is made to establish changes in serum and liver lipoprotein cholesterols accompanying Plasmodium berghei malarial infection in mice treated with aqueous extract of Ganoderma lucidum at 100, 250, and 500 mg/kg body weight in comparison with 15 mg/kg chloroquine (CQ). Significant increases in all the lipoprotein fractions were observed in infected untreated mice compared with normal control mice. Treatment with 100 and 250 mg/kg G. lucidum extract produced significant reduction in serum total cholesterol (TC) and low-density cholesterol (LDL-C) contents compared with 500 mg/kg G. lucidum and CQ. Treatment with CQ, however, produced significant reduction in hepatic TC and LDL-C compared with the extract. A dose-dependent significant increase in serum high-density lipoprotein cholesterol (HDL-C) was observed in the G. lucidum treated mice compared with normal control but significantly lower compared with CQ-treated mice. Liver HDL-C level was significantly higher in CQ-treated mice compared with normal control and significantly lower compared with G. lucidum-treated and infected untreated mice. A dose-dependent effect of the extract was observed in both serum and liver very-low density lipoprotein cholesterol (VLDL-C). The implication of these results is discussed with respect to the parasite survival and proliferation in the serum and liver.

Abstract
Ganoderma lucidum (G. lucidum), a traditional Chinese medicine, has been used for the treatment of various diseases including cancer and atherosclerosis. In this study, the positive effect of G. lucidum on metabolic syndrome was investigated in more detail by the use of 3T3-L1 pre-adipocyte cells. Treatment of 3T3-L1 cells with G. lucidum extract (GE) significantly promoted adipocyte differentiation and adiponectin production in a dose-dependent manner, as assessed by Oil-Red O staining, quantitative RT-PCR and ELISA. Treatment with GW9662, an inhibitor for peroxisome proliferator-activated receptor-gamma (PPARgamma), significantly attenuated GE-dependent adipocyte differentiation and adiponectin gene expression, suggesting the involvement of PPARgamma. Moreover, a reporter gene assay using GAL4-PPAR fusion proteins revealed that GE enhances GAL4-PPARgamma and GAL4-PPARalpha activities. These results indicate the presence of natural compounds possessing PPARgamma and PPARalpha activating properties in G. lucidum.

Abstract
The aim of the current study was to elucidate the potential therapeutic effect of Ganoderma lucidum polysaccharide peptide (GL-PP) in rheumatoid arthritis (RA). The effects of GL-PP on cell proliferation and cytokine production were studied in RA synovial fibroblasts (RASF). GL-PP significantly inhibited the proliferation of RASF. Following the incubation with GL-PP, production of interleukin (IL)-6 and monocyte chemoattractant protein (MCP)-1 in RASF were significantly increased as expressed as percentage change from basal values. However, the actual effects were minimal due to the low basal values. When RASF were activated by IL-1beta or lipopolysaccharides, IL-8 and MCP-1 production increased many folds. GL-PP significantly suppressed their productions. The inhibitory effects of GL-PP on cytokine production in RASF were at least in part, by inhibiting the nuclear factor-kappa B (NF-kappaB) transcription pathway. Our results demonstrated that GL-PP had the unique ability to modulate cytokine production in RASF and warrants further investigation into its mechanism of action.

Abstract
Reported utilisation of prescription drug use concurrently with herbal or vitamin products have increased, placing an estimated 15 million patients at risk of potential drug-supplement interactions. This systematic review aims to consolidate relevant herb and supplement interactions data available for some of the more common classes of interactions experienced by clinicians. These classes include: hypoglycaemic/hyperglycaemics; hypotensive/hypertensives, diuretics, sedatives, cardiac glycosides, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, laxatives, immunomodulators, agents that may increase the risk of bleeding or clotting, agents that may be hepatotoxic, agents that may have hormonal properties, and agents with cytochrome P450 enzyme activity. The format is designed to promote use as a decision support tool for healthcare providers.

Abstract
Nitric oxide (NO) is a principal mediator in many physiological and pathological processes. Overproduction of NO via the inducible nitric oxide synthase (iNOS) has cytotoxic effect through the formation of peroxynitrite with superoxide anion. The iNOS is mainly expressed in macrophages and is able to produce large amount of NO. The expression of iNOS is mainly regulated at the transcriptional level. The iNOS-mediated NO production plays a role in the development of atherosclerosis. Ganoderma lucidum (G. lucidum, Linzhi or Reishi) is a traditional herbal medicine which is commonly used as health supplement. Several studies have demonstrated its effectiveness against cancer, immunological disorders and cardiovascular diseases. The objective of the present study was to investigate the effect of G. lucidum on iNOS-mediated NO production in macrophages. Human monocytic cell (THP-1) derived macrophages were incubated with lipopolysaccharide (LPS) for 24 h. Such treatment significantly stimulated NO production (253% versus the control). Such a stimulatory effect was resulted from increased iNOS mRNA expression (270% versus the control) and iNOS activity (169.5% versus the control) in macrophages. The superoxide anion level was also elevated (150% versus the control) in LPS-treated macrophages. Treatment of macrophages with G. lucidum extract (100 microg/ml) completely abolished LPS-induced iNOS mRNA expression and NO production. Such an inhibitory effect of G. lucidum was mediated via its antioxidant action against LPS-induced superoxide anion generation in macrophages. These results suggest that G. lucidum may exert a therapeutic effect against atherosclerosis via ameliorating iNOS-mediated NO overproduction in macrophages.

Abstract
Traditional Chinese medicine (TCM) has many beneficial effects and has been practiced for several thousand years. It is known to treat the cause of a disease rather than to alleviate its symptoms. Based on a belief that TCM is natural, safe, and of lower cost, consumers worldwide are spending more out-of-pocket money on this form of therapy. This increased spending, and reports of adverse reactions, has drawn the attention of many regulatory agencies. Scientists have called for more evidence-based and scientific research on the risks and benefits of TCM. In Canada, the Natural Health Product Regulations came into effect January 2004. TCM herbal product manufacturers will need to provide products of reputable quality to the market. Many will apply modern technology and good science to support their products. The issues facing producers, scientists, and consumers alike are quality control and assessment, standardization of bioactive components, mechanisms of actions, and integration of the evolved modern Chinese medicine into the healthcare system. Solid science, better regulation of the final product, and better education of consumers are necessary to extract the best of TCM to complement existing conventional medicine to deliver the best healthcare.Key words: bioactive components, chromatographic fingerprinting, integration, mechanisms, Natural Health Product (NHP) Regulations, standardization, traditional Chinese medicine.

Abstract
The hot water extract of the mushroom Ganoderma lucidum was shown to have antioxidative effect against heart toxicity. Investigations into the mechanisms of action, level of lipid peroxidation level in vivo, and superoxide scavenging activity were also conducted. The mice were divided into six groups with ten animals in each group. Ganoderma lucidum, at doses of 10, 25 and 50 mg/kg (p.o.) was administered. Superoxide anions were assayed by UV spectrophotometer using the cytochrome C reduction method. The results of this study showed that Ganoderma lucidum exhibited a dose-dependent antioxidative effect on lipid peroxidation and superoxide scavenging activity in mouse heart homogenate. Additionally, this result indicated that heart damage induced by ethanol shows a higher malonic dialdehyde level compared with heart homogenate treated with Ganoderma lucidum. It is concluded that the antioxidative activity may therefore contribute to the cardioprotective effect of Ganoderma lucidum, and may therefore protect the heart from superoxide induced damage.

Abstract
INTRODUCTION There has been renewed interest in mushroom medicinal properties. We studied cholesterol lowering properties of Ganoderma lucidum (Gl), a renowned medicinal species. RESULTS Organic fractions containing oxygenated lanosterol derivatives inhibited cholesterol synthesis in T9A4 hepatocytes. In hamsters, 5% Gl did not effect LDL; but decreased total cholesterol (TC) 9.8%, and HDL 11.2%. Gl (2.5 and 5%) had effects on several fecal neutral sterols and bile acids. Both Gl doses reduced hepatic microsomal ex-vivo HMG-CoA reductase activity. In minipigs, 2.5 Gl decreased TC, LDL- and HDL cholesterol 20, 27, and 18%, respectively (P < 0.05); increased fecal cholestanol and coprostanol; and decreased cholate. CONCLUSIONS Overall, Gl has potential to reduce LDL cholesterol in vivo through various mechanisms. Next steps are to: fully characterize bioactive components in lipid soluble/insoluble fractions; evaluate bioactivity of isolated fractions; and examine human cholesterol lowering properties. Innovative new cholesterol-lowering foods and medicines containing Gl are envisioned.

Abstract
The antioxidative effect of hot water extract of the mushroom Ganoderma lucidum on ethanol-induced free radical generation had been studied. In order to further investigate the hepatic and renal protective mechanism of Ganoderma lucidum, rates of lipid peroxidation were determined. The hot water extract of Ganoderma lucidum dose-dependently exhibited antioxidative effect on mouse liver and kidney lipid peroxidation; our results indicated that hepatic and renal homogenates have a higher malonic dialdehyde level in an ethanol administered group than in the Ganoderma lucidum treated group. It was concluded that the hepatic and renal protective mechanism of Ganoderma lucidum, might be due at least in part to its prominent superoxide scavenging effect. Ganoderma extract could protect the liver and kidney from superoxide induced hepatic and renal damages.

Abstract
For centuries, Chinese medicine has regarded Ganoderma, a fungus (Myceteae, Amastigomycota, Busidomycetes, Aphyllophorales, Polyporaceae, Ganoderma) also known as 'Ling Zhi' in Mandarin, as a premium remedy for many diseases. Until now, no convincing data regarding its therapeutic effects in vivo on autoimmune diseases have been demonstrated. In this study, a controlled protocol was conducted in which New Zealand Black/White F1 mice were fed standard chow with prednisolone (0.5 mg/kg/day) or Ganoderma tsugae extract, commencing at 2 months of age. It was found that the F1 mice responded well to Ling Zhi extract. Ling Zhi improved the survival rate of lupus mice, decreased the amount of proteinuria, decreased serum levels of anti-dsDNA autoantibody, and showed evidence of decreased perivascular and parenchyma mononuclear cell infiltration in vital organs.

Abstract
Reactive oxygen species (ROS), such as superoxide anions and hydroxyl radicals, are associated with carcinogenesis and other pathophysiological conditions. Therefore, elimination or inactivation of ROS or inhibition of their excess generation may be beneficial in terms of reducing the risk for cancer and other diseases. Ganoderma lucidum has been used in traditional oriental medicine and has potential antiinflammatory and antioxidant activities. In the present study, we tested the amino-polysaccharide fraction (designated as 'G009') from Ganoderma lucidum for the ability to protect against oxidative damage induced by ROS. G009 significantly inhibited iron-induced lipid peroxidation in rat brain homogenates and showed a dose-dependent inactivation of hydroxyl radicals and superoxide anions. It also reduced strand breakage in phiX174 supercoiled DNA caused by UV-induced photolysis of hydrogen peroxide and attenuated phorbol ester-induced generation of superoxide anions in differentiated human promyelocytic leukaemia (HL-60) cells. These findings suggest that G009 from Ganoderma lucidum possesses chemopreventive potential.
