Abstract
Introduction: different lines of evidence have shown that ginger administration may be beneficial for patients with multiple sclerosis (MS). Therefore, we aimed to investigate the effect of ginger supplementation on disability, physical and psychological quality of life (QoL), body mass index (BMI), neurofilament light chain (NfL), interlukin-17 (IL-17), matrix metalloproteinase-9 (MMP-9), and neutrophil to lymphocyte ratio (NLR) in patients with relapsing-remitting MS. Methods: this was a 12 week double-blind parallel randomized placebo-controlled trial with a 3 week run-in period. The treatment (n = 26) and control (n = 26) groups received 500 mg ginger and placebo (corn) supplements 3 times daily, respectively. Disability was evaluated using the Expanded Disability Status Scale (EDSS). QoL was rated using the Multiple Sclerosis Impact Scale (MSIS-29). BMI was calculated by dividing weight by height squared. Serum levels of NfL, IL-17, and MMP-9 were measured using the enzyme-linked immunosorbent assay. NLR was determined using a Sysmex XP-300™ automated hematology analyzer. All outcomes were assessed before and after the intervention and analyzed using the intention-to-treat principle. Results: in comparison with placebo, ginger supplementation caused a significant reduction in the EDSS (-0.54 ± 0.58 vs. 0.08 ± 0.23, P < 0.001), the MSIS-29 physical scale (-8.15 ± 15.75 vs. 4.23 ± 8.46, P = 0.001), the MSIS-29 psychological scale (-15.71 ± 19.59 vs. 6.68 ± 10.41, P < 0.001), NfL (-0.14 ± 0.97 vs. 0.38 ± 1.06 ng mL-1, P = 0.049), IL-17 (-3.34 ± 4.06 vs. 1.77 ± 6.51 ng L-1, P = 0.003), and NLR (-0.09 ± 0.53 vs. 0.53 ± 1.90, P = 0.038). Nevertheless, the differences in BMI and MMP-9 were not significant between the groups. Conclusion: ginger supplementation may be an effective adjuvant therapy for patients with relapsing-remitting MS.

Effects of almond intake on oxidative stress parameters: A systematic review and meta-analysis of clinical trials. Complement Ther Med 2023; 73:102935. [PMID: 36842635 DOI: 10.1016/j.ctim.2023.102935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 02/16/2023] [Accepted: 02/23/2023] [Indexed: 02/26/2023] Open
Abstract
BACKGROUND AND AIMS Several randomized controlled trials (RCTs) have shown that almonds can improve oxidative stress indices, but the results are controversial. Therefore, the goal of this research was to carry out a systematic review and meta-analysis of all RCTs that evaluated the effect of almonds on selected oxidative stress indices. METHODS A systematic search was conducted up to April 2022 on PubMed, Scopus, Web of Science, and Google Scholar. We have selected the studies that investigated the effects of almonds on malondialdehyde (MDA), and oxidized low-density lipoprotein (Ox-LDL) levels in adults. Data were pooled by using the random-effects model. The risk of bias in individual studies was assessed using the Cochrane Collaboration risk of bias tool. RESULTS Seven RCTs involving 424 participants were analyzed. The results indicated that almond intake led to a significant decrease in MDA levels (WMD: - 6.63 nmol/ml; 95 % CI: - 8.72 to - 4.54; P < 0.001). However, no significant effect was observed on Ox-LDL (Hedges' g: - 0.12; 95 % CI: - 0.34 to 0.10; P = 0.28). Sensitivity analysis showed that overall estimates were not affected by the elimination of any study. We did not observe any evidence regarding publication bias. CONCLUSION The present meta-analysis suggests that almond intake can improve MDA levels and might play a beneficial role in the reinforcement of the antioxidant defense system and amelioration of oxidative stress in adults. There is a need for more studies with larger groups to better estimate this effect.

A subcritical water extract of soil grown Zingiber officinale Roscoe: Comparative analysis of antioxidant and anti-inflammatory effects and evaluation of bioactive metabolites. Front Pharmacol 2023; 14:1006265. [PMID: 36843947 PMCID: PMC9945201 DOI: 10.3389/fphar.2023.1006265] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Accepted: 01/16/2023] [Indexed: 02/10/2023] Open
Abstract
Introduction: Ginger (Zingiber officinale Roscoe) can scavenge free radicals, which cause oxidative damage and inflamm-ageing. This study aimed to evaluate the antioxidant and anti-inflammatory effects of soil ginger's sub-critical water extracts (SWE) on different ages of Sprague Dawley (SD) rats. The antioxidant properties and yield of SWE of soil- and soilless-grown ginger (soil ginger and soilless ginger will be used throughout the passage) were compared and evaluated. Methods: Three (young), nine (adult), and twenty-one (old) months old SD rats were subjected to oral gavage treatments with either distilled water or the SWE of soil ginger at a concentration of 200 mg/kg body weight (BW) for three months. Results: Soil ginger was found to yield 46% more extract than soilless ginger. While [6]-shogaol was more prevalent in soilless ginger, and [6]-gingerol concentration was higher in soil ginger (p < 0.05). Interestingly, soil ginger exhibited higher antioxidant activities than soilless ginger by using 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assay. With ginger treatment, a reduced levels of tumour necrosis factor-α (TNF-α) and C-reactive protein (CRP) but not interleukin-6 (IL-6) were observed in young rats. In all ages of SD rats, ginger treatment boosted catalase activity while lowering malondialdehyde (MDA). Reduction of urine 15-isoprostane F2t in young rats, creatine kinase-MM (CK-MM) in adult and old rats and lipid peroxidation (LPO) in young and adult rats were also observed. Discussion: The findings confirmed that the SWE of both soil and soilless grown ginger possessed antioxidant activities. Soil ginger produced a higher yield of extracts with a more prominent antioxidant activity. The SWE of soil ginger treatment on the different ages of SD rats ameliorates oxidative stress and inflammation responses. This could serve as the basis for developing a nutraceutical that can be used as a therapeutic intervention for ageing-related diseases.

Abstract
This umbrella review is to recapitulate and grade the available evidence of associations between consumption of Zingiberaceae plants/curcumin (Cur) and multiple health-related outcomes. This study included 161 meta-analyses of randomized controlled trials in 76 articles with 67 unique health outcomes. Data on heterogeneity and publication bias are considered to assess the quality of evidence. Based on the different impact of Zingiberaceae plants/Cur on human health, the advantages outweigh the disadvantages. Zingiberaceae plants/Cur can mainly improve metabolic syndrome, non-alcoholic fatty liver disease, cardiovascular disease, and some chronic inflammatory diseases, likewise, obviously relief the pain of osteoarthritis and related diseases. Ginger supplements have been shown to improve vomiting during pregnancy and to relieve nausea and vomiting caused by chemotherapy and surgery. The surgery is any type of surgery, including laparoscopic surgery, gynecological surgery and mixed surgery. Beneficial associations were found with Cur intervention in gastrointestinal, neurological and oral diseases. Zingiberaceae plants/Cur are generally safe and favorable for multiple health outcomes in humans. High-quality research is further needed to prove the observed associations.

Effects of medical plants from Zingiberaceae family on cardiovascular risk factors of type 2 diabetes mellitus: A systematic review and meta-analysis of randomized controlled trials. J Food Biochem 2022; 46:e14130. [PMID: 35332564 DOI: 10.1111/jfbc.14130] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 03/06/2022] [Accepted: 03/08/2022] [Indexed: 11/27/2022]
Abstract
We performed a meta-analysis on randomized controlled trials (RCTs) to evaluate the efficacy of Zingiberaceae on cardiovascular risk factors in type 2 diabetes mellitus (T2DM). PubMed, Web of Science, Embase, The Cochrane Library, and Scopus were searched systematically until October 18, 2021. Thirty-four RCTs with 2154 patients met our inclusion. Pooled analysis indicated that Zingiberaceae can significantly improve body weight (BW) (WMD = -1.012, 95% CI: -1.673, -0.351, p = .003), fasting blood glucose (FBG) (WMD = -14.292, 95% CI: -18.588, -9.995, p < .001), glycosylated hemoglobin 1c (HbA1c) (WMD = -0.432, 95% CI: -0.607, -0.257, p < .001), serum insulin (WMD = -2.036, 95% CI: -2.857, -1.216, p < .001), homeostasis model assessment insulin resistance (HOMA-IR) (WMD = -0.886, 95% CI: -1.375, -0.398, p < .001), high density lipoprotein-cholesterol (HDL-C) (WMD = 0.850, 95% CI: 0.018, 1.682, p = .045), triglyceride (TG) (WMD = -17.636, 95% CI: -27.121, -8.151, p < .001), diastolic blood pressure (DBP) (WMD = -0.642, 95% CI: -1.148, -0.137, p = .013), C-reactive protein (CRP) (WMD = -0.623, 95% CI: -1.061, -0.186, p = .005), tumor necrosis factor-α (TNF-α) (WMD = -3.020, 95% CI: -4.327, -1.712, p < .001), and interleukin 6 (IL-6) (WMD = -1.147, 95% CI: -1.887, -0.406, p = .002). The supplementation of Zingiberaceae may be an effective adjunctive therapy in management of T2DM and prevention cardiovascular complications by decreasing BW, improving blood glucose control, insulin resistance, lipid profiles (HDL-C and TG), blood pressure (DBP), and reducing inflammation (CRP, TNF-α, and IL-6). PRACTICAL APPLICATIONS: Approximately half of the deaths of individuals with diabetes mellitus (DM) are attributable to cardiovascular disease (CVD), and individuals with T2DM have a two-fold increased risk of cardiovascular mortality than healthy individuals. Currently, T2DM is mainly treated with hypoglycemic medication such as sulfonylureas, thiazolidinediones, meglitinides, and biguanides. Nevertheless, most of them with long-term usage could cause side effects, including hypoglycemia and gastrointestinal troubles. Several species of the Zingiberaceae family are used in traditional herbal medicines, which have been widely used in traditional and complementary medicine. Proving the potential benefits of Zingiberaceae on T2DM and its cardiovascular complications has positive clinical implications for the use of this practical herb.

Abstract
Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide. Inflammation and oxidative stress play critical roles in progression of various types of CVD. Broad pharmacological properties of ginger (the rhizome of Zingiber officinale) and its bioactive components have been reported, suggesting that they can be a therapeutic choice for clinical use. Consistent with its rich phenolic content, the anti-inflammatory and antioxidant properties of ginger have been confirmed in many studies. Ginger modifies many cellular processes and in particular was shown to have potent inhibitory effects against nuclear factor kappa B (NF-κB); signal transducer and activator of transcription; NOD-, LRR-, and pyrin domain-containing proteins; toll-like receptors; mitogen-activated protein kinase; and mammalian target of rapamycin signaling pathways. Ginger also blocks pro-inflammatory cytokines and the activation of the immune system. Ginger suppresses the activity of oxidative molecules such as reactive oxygen species, inducible nitric oxide synthase, superoxide dismutase, glutathione, heme oxygenase, and GSH-Px. In this report, we summarize the biochemical pathologies underpinning a variety of CVDs and the effects of ginger and its bioactive components, including 6-shogaol, 6-gingerol, and 10-dehydrogingerdione. The properties of ginger and its phenolic components, mechanism of action, biological functions, side effects, and methods for enhanced cell delivery are also discussed. Together with preclinical and clinical studies, the positive biological effects of ginger and its bioactive components in CVD support the undertaking of further in vivo and especially clinical studies.

Effect of ginger (Zingiber officinale) supplementation on oxidative stress parameters: A systematic review and meta-analysis. J Food Biochem 2021; 45:e13612. [PMID: 33458848 DOI: 10.1111/jfbc.13612] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 12/13/2020] [Accepted: 12/27/2020] [Indexed: 11/29/2022]
Abstract
A wide variety of antioxidant properties are attributed to ginger (Zingiber officinale) and several randomized controlled trials (RCTs) have investigated the effect of ginger intake on major oxidative stress (OS) parameters. We conducted a systematic review and meta-analysis to evaluate the effects of using ginger to improve OS levels. Medline, Scopus, ISI Web of Science, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched up until March 2020 to gather RCTs that evaluated the impact of ginger intake on the levels and activity of OS parameters in adult subjects. Means and standard deviations for relevant OS variables were extracted and evaluated to assess the quality of the trials based on the Cochrane risk-of-bias tool for randomized trials. The gathered data were pooled and expressed as standardized mean difference (SMD) with 95% Confidence Intervals (95% CI). Twelve trials were included in this review. Ginger intake was shown to significantly increase glutathione peroxidase (GPx) activity (SMD: 1.64; 95% CI: 0.43, 2.85; I2 = 86.8%) and total antioxidant capacity (TAC) (SMD: 0.40; 95% CI: 0.06, 0.73; I2 = 42.8%) and significantly decrease malondialdehyde (MDA) levels (SMD: -0.69; 95% CI: -1.26, -0.12; I2 = 85.8%) compared to control groups. Ginger supplementation also non-significantly associated with an increase in CAT activity (SMD: 1.09; 95% CI: -0.07, 2.25; I2 = 87.6%). This systematic review and meta-analysis presents convincing evidence supporting the efficacy of ginger supplementation on improving OS levels. PRACTICAL IMPLICATIONS: In health sciences, OS, due to its pivotal role in the pathophysiology of several chronic diseases, is a subject with a long history. Recent research strives for a safe, ideal, and effective antioxidant. Ginger is herbal medicine, which has been widely used in traditional and complementary medicine. Proving the antioxidant effect and potential benefit of ginger has positive clinical implications for the application of this practical herb.
