Bioactive compounds from plants have potential antimicrobial activity. The aim of this in vitro study was to evaluate the antimicrobial efficacy of curcumin, allicin, gingerol and cinnamon compared to 4% sodium hypochlorite (NaOCl) against Enterococcus faecalis and its biofilm.

The dry herbal compounds were diluted with dimethyl sulfoxide (DMSO). Antimicrobial activity was evaluated using agar diffusion test, minimum inhibitory concentration (MIC) assay, minimum bactericidal concentration (MBC) test, time kill study, and biofilm susceptibility assay. The zone of inhibition (ZOI) was determined using agar diffusion test on Muller Hinton (MH) agar plates. MIC was evaluated using the tube dilution method. Root canals of extracted human anterior teeth were instrumented, split into two halves, autoclaved, and incubated with brain heart infusion broth containing E. faecalis for 21 days to form a biofilm. The susceptibility of the biofilm to the test solutions was evaluated by counting bacterial colonies on MH agar.

NaOCl exhibited potent antimicrobial activity under all tested parameters. Allicin showed a significantly greater ZOI, while curcumin showed the least MIC among the tested herbal extracts (P < 0.05). MBC varied widely among the groups with no significant difference between allicin and cinnamon (P > 0.05). Gingerol and cinnamon were significantly superior to the other groups killing E. faecalis within 4-4.2 min (P < 0.05). Curcumin, gingerol, and cinnamon were equally efficacious as NaOCl in completely eradicating E. faecalis biofilm (P > 0.05).

NaOCl emerged as the most efficacious antibacterial agent and all herbal extracts showed significant antibacterial activity against E. faecalis.

The toxicity induced by toxic substances and medications is one of the principal reasons for acute kidney injury. The purpose of this study was to investigate the effect of Cinnamomum zeylanicum and Zingiber officinale extracts on the kidney of the rats intoxicated with carbon tetrachloride (CCl4).

In this study, thirty-six Wistar rats randomly divided into six groups: I) control, II) cinnamon 25mg/kg + ginger 125mg/kg, III) CCl4, IV) CCl4+ cinnamon 50mg/kg, V) CCl4+ ginger 250mg/kg, VI) CCl4+ cinnamon 25mg/kg and ginger 125mg/kg. Cinnamomum zeylanicum and Zingiber officinale extracts were injected for 14 days. On the 14th day, the rats in the CCl4 and the pretreatment groups were administered with 1mg/kg of CCl4 and olive oil mixture (1:1 v/v). Forty-eight hours after the injection of CCl4, blood samples were taken to conduct subsequent biochemical tests. Also, the kidney removed and histological alterations as well as oxidative markers were investigated.

The administration of CCl4 increased the levels of urea, uric acid, creatinine and malondialdehyde; while decreased the levels of serum albumin, total protein, total antioxidant capacity and renal tissue antioxidant enzymes. Pretreatment with Cinnamomum zeylanicum and Zingiber officinale extracts, especially with a combination of them, led to considerable improvement in these values compared to the CCl4 group.

The results suggest that hydroalcoholic extracts of Cinnamomum zeylanicum and Zingiber officinale, alone or simultaneously, have protective effects against free radicals produced during CCl4 metabolism.

The purpose of this work was to estimate the anti-cancer properties of the nanoemulsions synthesized by Zingiber officinale L. tincture against PC3 prostate cancer cells.  Fresh ginger was initially procured from a local market, and extraction was performed after complete washing. In the next step, a nanoemulsion containing ginger extract was prepared using Tween 80, and its size and zeta potential were determined by a Zetasizer. The prepared nanoemulsion was assessed by transmission electron microscopy (TEM) to confirm the size and morphology of the particles. The toxicity of the nanoemulsion containing ginger extract against PC3 prostate cancer cells and normal HFF skin cells was evaluated using the MTT assay. To determine apoptosis, flow cytometry was used to assess cell cycle changes. In addition, the antioxidant activity of the nanoemulsion was estimated by DPPH and ABTS free radical scavenging tests.  The results showed that the prepared nanoparticles had a size of 67 nm (confirmed by TEM electron microscopy) and a zeta potential of -25.05 mV. The results of the MTT assay showed inverse dose-dependent toxicity for different concentrations of ginger nanoemulsion against PC3 cells. In addition to anti-cancer activity, the nanoemulsion showed a potent ability to scavenge DPPH and ABTS free radicals.  Our results showed that the nanoemulsions containing ginger extract had toxicity against PC3 cancer cells but not normal cells, indicating their applicability as a suitable option for treating PC.

Zingiber officinale extract can control cardiovascular risk factors. Moreover, endurance training may effectively rehabilitate myocardial infarction by strengthening the myocardial muscle tissue. In-silico analysis identified essential genes involved in the heart damage process based on data from the DisGeNET database. Hence, we estimated the affinity of chemical and bioactive molecules for PPARγ. Therefore, this study aimed to investigate the effect of endurance exercise alone or combined with Zingiber officinale extract on Myocardial infarction rats.

Twenty-five male rats were randomly divided into five groups, including (1) group of myocardial infarctions (MI) induced by subcutaneous injection of isoproterenol, (2) myocardial infarction+exercise (MI+EX), (3) myocardial infarction+Zingiber Officinale extraction administered orally (MI+GE), (4) myocardial infarction+exercise+Zingiber Officinale extract (MI+EX+GE), and (5) Control group. The qPCR-Real Time technique was used to measure the expression of PGC1-ɑ, PPARγ, and TNF-ɑ genes. We evaluated the concentration of Troponin-1 as a vital myocardial ischemia marker.

In bioinformatics analysis, we found that the PPARγ, PGC1-ɑ, and TNF-ɑ pathways were critical in heart injury. Also, the effects of Zingiber officinale on heart tissue were detected through PPARγ by drug design. Endurance training combined with Zingiber officinale consumption reduced the expression of TNF-ɑ, Troponin-1 and increased the PGC1-ɑ, PPARγ genes. Furthermore, consumption of Zingiber officinale extraction improved the levels of PGC1-ɑ, PPARγ, TNF-ɑ, and Troponin-1.

Our data indicated that six weeks of endurance training and consumption of Zingiber officinale extract could reduce the relative expression of the TNF-ɑ and significantly increase the level of PGC1-ɑ, PPARγ.

Since synthetic chemotherapeutic drugs produce a certain degree of drug resistance and due to their common side effects, such as damage to hematopoietic cells and hair loss, it is necessary to use herbal medicine as a substrate to develop new anticancer drugs. The ingredients of three essential oils (EO) were identified using gas chromatography–mass spectrometry (GC-MS) analysis. Their anticancer activities have been investigated on four human breast cancer cell lines, including MCF-7, MDA-MB-175, MDA-MB-231, and MDA-MB-468. In addition, their antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The three plants were investigated for identifications of the ingredients of their EOs, and major ingredients were identified in each plant as alpha-phellandrene (26.75 %) in Anethum graveolens L., limonene (61.83 %) in Citrus limon (L.) Osbeck, and zingiberene (30.28 %) in Zingiber officinale Roscoe. Among the EOs, C. limon was significantly more effective than others; its half-maximal inhibitory concentration (IC50) on MCF-7 was obtained at 201 µg.mL-1. Furthermore, Z. officinale EO showed a higher antioxidant activities in comparison to the two other EOs. Considering the antioxidant and anticancer effects of the EOs, they could be further investigated as a possible complementary medicine in cancer.

Liver is the most important organ of drugs and xenobiotics metabolism and any damage to the liver is associated with dysfunction of this organ. This study was carried out to find the possible additive effect of the co-administration of Cinnamomum zeylanicum (cinnamon) and Zingiber officinale (ginger) extracts on carbon tetrachloride (CCl4)-induced liver damage in rats.
Forty-two male Wistar rats were randomly divided into 7 groups (n=6). Group I: Normal control, Group II: Control of the extract (25 mg/kg of cinnamon extract and 125 mg/kg of ginger extract), Group III: CCl4 control, Group IV: 50 mg/kg of cinnamon extract; Group 5: 250 mg/kg of ginger extract; Group VI: As in group II, a combination of 25 mg/kg cinnamon extract and 125 mg/kg ginger extract, and group VII: 100 mg/kg of silymarin (as the standard drug). These treatments were performed daily for 14 days. On the fourteenth day, all groups received 1ml of CCl4 along with olive oil (1:1 v/v), except for the groups I and II. The last two groups received only olive oil.
Intraperitoneal injection of CCl4 into rats significantly increased the levels of liver enzymes, bilirubin, and malondialdehyde (MDA), and decreased total antioxidant and total protein levels compared to the control group (P<0.001). Pre-treatment with a combination of cinnamon and ginger extracts significantly improved these factors.
The results of this study showed that co-administration of cinnamon and ginger extracts is more efficient in protecting liver from the damaging effects caused by CCl4.

According to investigators’ findings, pain after periodontal flap surgery is a common occurrence so that its control is very important in the treatment procedure. Although Ibuprofen is the most common drug for the pain control in dentistry, this drug has its own side effects. The purpose of this investigation is to compare the prophylactic and post operation effect of ginger; Zingiber Officinale (Zintoma) and Ibuprofen on the pain after surgical treatment of periodontal flap.

The samples of this study were collected from 46 patients attending the dental clinic in Guilan University of Medical Sciences, Rasht, Iran. Patients were classified into three groups. The first group received placebo, the second group received Ibuprofen and the third group received Zintoma. The amount of pain were recorded by two main measurement criteria of VAS and VRS at different times and then the data were analyzed using SPSS21. P value was considered <0.05.

12 hours after surgery, most patients in Ibuprofen group (n=39) and Zintoma group (n=36), reported no pain while, most patients in placebo group (n=25), reported less pain. Statistical analysis shows that the Zintoma group had significantly more effect on pain.

It seems that Zintoma has almost the same impact of Ibuprofen in reducing the pain. While it has less side effects, it is better to use it as an analgesic drug in controlling the pain after periodontal flap surgery.

The aim of this study is to assess the impact of Cinnamomum verum, Mentha spicata, Zingiberene officinal on polycystic ovary syndrome (PCOS) treatment.

MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Scopus, Web of Science, Google Scholar, ProQuest, Clinicaltrial.gov, and for Persian articles SID, Magiran, Irandoc, and Iranmedex were searched without any time limitation.

Thirteen randomized controlled trials (RCTs) consisting 668 women were entered in the meta-analysis. Significant differences in fasting blood sugar (FBS; weighted mean difference (WMD)=-3.69 mg/dL, 95% CI: -6.67 to -0.7, P=0.02; 241 participants), fasting insulin (WMD=-4.53 µIU/mL, 95% CI: -6.45 to -2.61, P<0.001;183 participants), triglyceride (TG; WMD=-17.97 mg/ dL, 95% CI: -30.51 to -5.43, P=0.005;183 participants), total cholesterol (TC; WMD=-14.60 mg/dL, 95% CI: -22.93 to -6.26, P=0.0006; 183 participants), low-density lipoprotein cholesterol (LDL; WMD=-16.58 mg/dL, 95% CI -23.91 to -9.24, P<0.001; 183 participants), malondialdehyde (MDA; WMD=-0.25 nmol/ml, 95% CI -0.41 to -0.09, P<0.002;124 participants), total testosterone (TT; WMD=-0.18 ng/mL, 95% CI -0.27 to -0.09, P<0.001; 116 participants), free testosterone (FT; WMD=-5.47 pg/mL, 95% CI -8.34 to -2.61, P=0.0002;78 participants) were obtained by using cinnamon alone and herbal mixture containing cinnamon in comparison to control.

This meta-analysis showed that cinnamon alone and herbal mixture containing cinnamon improve level of FBS, fasting insulin, TG, TC, LDL, MDA, TT, and FT serum level.

The present study aimed to assess the effect of ginger (Zingiber officinale) powder supplementation on Helicobacter pylori eradication and improvement of dyspeptic symptoms in patients with H. pylori positive functional dyspepsia (FD). During this pilot study 15 patients with H. pylori positive FD received 3 g/d ginger powder as three 1-g tablets for 4-weeks. Dyspepsia symptoms were asked before and after the intervention using a questionnaire based on the Rome III criteria. H. pylori eradication was also assessed by a non-invasive stool antigen (HpSAg) test. Ginger consumption accompanied by significant H. pylori eradication rate of 53.3% (P = 0.019) and the odds ratio (95% CI) was 8 (1.07 to 357.14). Moreover, our results showed significant changes in most of the dyspepsia symptoms after ginger supplementation. According to our findings, Z. officinale can be considered as a useful complementary therapy for FD. However, due to the small number of clinical trials in this area, further welldesigned clinical trials are needed to explicitly talk about its effectiveness especially about the eradication of H. pylori.

Zingiber officinale (Zingiberaceae family) is traditionally used in alternative medicine to reduce pain from rheumatoid arthritis and osteoarthritis. Ginger is also often applied for stomach and chest pain, toothaches and as anti-inflammatory agent. The aim of this study is to investigate analgesic and anti-inflammatory activities of Z. officinale dense extract after its transdermal delivery using allyl isothiocyanate (AITC) induced model with further discussion of possible action mechanism of ginger phytoconstituents. Inflammation was induced by subplantar injection to the plantar fasciitis (aponeurosis) of the hind limb of rats using 30 µL AITC solution (100 µg/limb) in 1,2-propyleneglycol. The dynamics of changes of inflammatory process was evaluated before addition of the inflammation inducer and after 1, 2, 3, 4, 6 and 24 hours of its injection for measuring the volume and the thickness of affected limb. Analgesic activity of ointments with ginger extract was examined using the model of AITC-induced pain. The most effective inhibition of the development of inflammation process was 0.025% ointment with ginger extract, and the highest anti-nociceptive effect was observed at the application of 0.05% ointment 10 minutes before pain inducer agent. Zingiber officinale dense extract was revealed to possess significant antinociceptive and anti-inflammatory actions after its transdermal delivery. Since the pharmacological effects of ginger extract have been investigated on AITC-induced model, we may suggest the vital role of phytoconstituents binding to TRPA1 and TRPV1 ion channels as possible mechanism of action.

Acute and chronic ethanol consumption causes oxidative stress in the liver and Zingiber officinale Roscoe (ginger) ginger improves the function of the liver. In the present study, the hepatoprotective effects of ginger extract on liver enzymes, lipid profiles, and indices of oxidative stress, including antioxidant enzymes activity and Malondialdehyde (MDA) against hepatotoxicity induced by ethanol in male rats was evaluated. Twenty-eight adult male Sprague-Dawley rats were randomly allocated to four groups and were treated daily for 28 days as follows: group I: control (received normal saline), group II: ginger (1 g/kg/day ginger extract solution in saline by oral gavage), group III: ethanol (4 g/kg/day ethanol by oral gavage), and group IV: ginger + ethanol. At the end of the experimental period, obtained sera from blood samples were used for assessment of liver enzymes and lipids, and liver tissue homogenate was used for estimating oxidative biomarkers. Furthermore, total phenolics content and in vitro antioxidant potential of ginger extract was determined to correlate hepatoprotective activity with phytochemical and antioxidant activity. In the ethanol group, the results showed a significant increase in biomarkers of oxidative stress and liver function biomarkers compared to other groups (P < 0.05). The level of altered enzyme markers was ameliorated significantly in the ginger co-treatment (ginger + ethanol) group (P < 0.05), while no significant difference in biochemical parameters were observed in ginger alone and control groups. It can be concluded that ginger extract has protective effects against toxicity induced by ethanol in the liver of male rats. The protective effect may be attributed to the presence of phenolics and flavonoids components

Root of dietary ginger considerably improves the activity of antioxidant enzymes in reproductive system and reduces the signs of cell damage in testis tissues. The present study conducted numerous sperm, hormonal, bio-chemical analysis and gene expression in order to evaluate the reproductive damages caused by exposure to formaldehyde (FA) and to investigate the ameliorative properties of co-administration of FA and Zingiber officinale (Ginger) in mice model. Forty-eight male NMRI mice were randomized into 6 groups of 8 animals each, including control group, control sham (received distilled water by gavage), FA group (10 mg/kg twice per day), intraperitoneally (i.p) and 3 FA groups (10 mg/kg i.p) + Ginger (500, 1000 and 2000 mg/kg/d by gavage, respectively). Sperm parameters, sexual hormones, antioxidant activity and expression of Bax and Bcl-2 genes were analyzed after 35 days. FA significantly diminished sperm parameters, sexual hormones and antioxidant enzymes (P < 0.05). Also, the expression of Bcl-2 and Bax genes had significant (P < 0.05) increase and decrease, respectively in FA group. Co-administration of Ginger extract significantly recovered the above parameters. Co-administration of Ginger extract ameliorates reproductive damages of FA by its androgenic, antioxidant and anti-apoptotic properties. Hence, it might be beneficial in these patients.

Recently, herbal medicine is widely used as an alternative and complementary therapy in several neurological disorders such as epilepsy. The anti-inflammatory and neuroprotective effects of Zingiber officinale or ginger have been well-documented. The present study was designed to evaluate the effects of ginger extract pre-treatment on seizures behavior, neuronal density and astrocytes activation in pentylenetetrazol (PTZ)- induced kindling model.
Kindling model was induced in mice by repetitive administration of PTZ at sub convulsive dose. Hydroalcoholic extract of ginger at doses of 25, 50 or 100 mg/kg were daily injected 10 days before PTZ injections and intraperitoneal administration of extract was continued 1h before each PTZ injection. Immunostaining against NeuN and GFAP as neuronal and astrocyte markers, respectively, was carried out on brain tissue sections.
Our data showed that ginger extract pre-treatment, especially at dose of 100 mg/kg, reduced the seizures behavior in PTZ receiving animals. Immunostaining against NeuN biomarker demonstrated that neuronal death was alleviated in animals under treatment of ginger extract. Furthermore, application of ginger extract attenuated the number of GFAP expressing cells in hippocampus of fully-kindled animals.
Overall, our data suggest that ginger pre-treatment exerts significant neuroprotective effect by attenuation of astrocytes activation in PTZ-induced kindling model. It can be concluded that ginger might be used as effective supplementary agent in epileptic patients.

Zingiber officinale Roscoe, commonly known as ginger, is used as a cooking spice and therapeutically for its antioxidant and androgenic activities. We investigated the effects of Z. officinale hydro-alcoholic extract on HMG-CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase level in the testis of streptozotocin (STZ)-induced diabetic rats.
The current experimental study was performed on four groups of male Wistar rats one of them was kept as a healthy control, while the others were rendered diabetic via a single intraperitoneal injection of STZ (60 mg kg-1). One group was considered as diabetic control; while the others were given orally hydro-alcoholic extract (200 and 400 mg kg-1) for 56 consecutive days. Body weight, blood glucose and insulin concentrations were evaluated using standard methods. The HMG-COA reductase level was determined by western blot analysis.
Treatment with the extract resulted in a significant reduction of serum glucose concentration and HMG-COA reductase level in the rat’s testis compared to diabetic controls (P Ginger has a potential influence on the regulation of cholesterol homeostasis by modulating of HMG-COA reductase level. The results provide scientific evidence to confirm the traditional use of Z. officinale in the treatment of diabetes mellitus.

Iron overload in the body is related with toxic effects and threatens the health. The aim of this study was to evaluate the protective role of hydroalcoholic extract of ginger (Zingiber officinale) against ferrous sulfate-induced hepatic and renal functional disorders and histological damages in rats.
The rats were divided into four groups (n=7): Sham, Sham G.E (ginger extract, 400 mg/kg/day for 14 days), FS (ferrous sulfate, 30 mg/kg/day for 14 days), FS.E (ferrous sulfate, 30 mg/kg/day for 14 days; ginger extract, 400 mg/kg/day for 11 days from the fourth day of ferrous sulfate injection). After 24 hr, blood, urine and tissue samples were collected.
Compared with Sham and Sham G.E groups, administration of ferrous sulfate resulted in liver and kidney dysfunction as evidenced by significantly higher levels of serum hepatic markers and bilirubin, and lower levels of serum albumin, total protein, triglyceride, cholesterol and glucose, as well as lower creatinine clearance and higher fractional excretion of sodium (p In conclusion, ginger extract appears to exert protective effects against ferrous sulfate-induced hepatic and renal toxicity by reducing lipid peroxidation and chelating iron.
