Abstract
Sleep is a dynamic and controlled set of physiological and behavioural practices during which the stabilisation and restoration processes of the body take place properly. Therefore, sleep disorders, especially chronic insomnia, can harm an individual's physical and mental health. However, the therapeutic alternatives are limited and possess severe side effects. Thus, in this study, we aimed to investigate the anti-insomnia effect of a polyherbal formulation (Sleep) (SLP) on p-chlorophenyalanine (PCPA) induced insomnia in rats. Intraperitoneal injection of PCPA induced the experimental condition, and the therapeutic effect of SLP was evaluated by studying the sleep pattern and expression of various neurotransmitters and receptors, along with neurotrophins. Moreover, insomnia-associated oxidative stress and inflammation were also studied. From the findings, we found that the SLP-supplemented animals improved their sleeping behaviour and that the major neurotransmitters, hormones, and receptors were maintained at an equilibrium level. Furthermore, the neurotrophin level was increased and pro-inflammatory cytokines were reduced. The evaluation of oxidative stress markers shows that the antioxidants were significantly boosted, and as a result, lipid peroxidation was prevented. The overall findings suggest that SLP can be used as an effective medication for the treatment of sleep disorders like insomnia as it triggers the major neurotransmitter system.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inflammation is a complex biological response of the tissue to noxious stimuli, which causes several debilitating inflammatory disorders. Currently, various conventional medicines are available, but their consumption causes adverse effects, hence researchers focused on alternatives like medical herbs from natural sources, as one of the most promising sources of therapeutic agents for inflammation. Febrojith is a well-known traditional Ayurvedic formulation obtained from the treasures of Ayurveda with a unique blend of herbs that are used effectively in preventing and combating a broad spectrum of infections, fevers, and also enhancing immunity for many years. However, its anti-inflammatory, efficacy and underlying mechanism remained unexplored. AIM OF THE STUDY In the present study, we investigated the chemical characterization and in vivo anti-inflammatory efficacy of Febrojith (FB) on acute and chronic inflammatory models via inhibiting inflammation and oxidative stress. MATERIALS AND METHODS FB was analyzed for chemical characterization & its phytoconstituents by UV-Vis spectrum, FT-IR, and GC-MS analysis. The anti-inflammatory activity of FB was studied on carrageenan-induced acute and adjuvant-induced chronic experimental models. The inflammatory cytokines and mediators were measured using the ELISA & Colorimetry techniques. Histopathology and cytology of paw tissue and synovium were analyzed by H&E and Papanicolau's (PAP)-staining methods. RESULTS 100 mg/kg bwt was found to be a potent dose from the carrageenan model and evaluated its effect in the adjuvant-induced chronic arthritic model. In the chronic model, 84% of edema inhibition was observed at the dose of 100 mg/kg bwt. Moreover, the supplementation of FB was shown to significantly (p ≤ 0.05) decrease the TBARS level and activity of myeloperoxidase in the paw tissue. In addition, adjuvant-induced production of various pro-inflammatory cytokines like TNF-α, IL-1β, IL-6, PGE2, NO and COX-2 were suppressed in inflamed rats subjected to FB supplementation. It also revealed that FB supplementation significantly (p ≤ 0.05) reduced the haematological markers. From the histopathology and cytological analysis, we found a reduction in the edema formation, and infiltration of inflammatory cells after the supplementation of FB. CONCLUSION In conclusion, FB might be used as an effective and potent drug against inflammation.

Abstract
Introduction Coronavirus disease 2019 (COVID-19) is a serious concern of the new era. Along with antiviral synthetic medications, there is a need to discover efficacious herbal antiviral medicines with minimum side effects in patients against COVID-19. This study aimed to assess the efficacy and safety of Imusil® among patients with mild COVID-19. Methods A prospective, randomized, multicenter, open-label, interventional study was conducted in patients with mild COVID-19 infection. Patients received either Imusil one tablet four times a day (seven days) along with the standard of care (SoC) or only SoC. The study endpoints were reverse transcription-polymerase chain reaction (RT-PCR) negativity, changes in cycle threshold (CT), clinical improvement, change in blood inflammatory indexes, and safety assessment. Results A total of 100 patients were enrolled, and 98 received at least one dose of treatment. The median age of patients was 36.0 years, and 58 were males. By day 4, 85.4% of patients in the Imusil+SoC group tested negative for RT-PCR compared to 64% of patients exhibiting the same outcome in the SoC group (P=0.0156). After eight days, clinical improvement was observed in all patients from the Imusil+SoC group, while in the SoC group, clinical improvement was observed in 94.0% of patients (P=0.4947). During follow-up visits, the average C-reactive protein (CRP) levels decreased from baseline in both treatment groups. The decrease in the levels of CRP (-7.3 mg/dL versus -5.5 mg/dL), D-dimer (-231.0 ng/mL versus -151.6 ng/mL), and interleukin 6 (IL-6) (-2.3 pg/mL versus -2.0 pg/mL) at eight days was comparatively higher in the Imusil+SoC group versus the SoC group. There were no serious treatment-emergent adverse events in the drug arm. Conclusion Imusil provides effective antiviral activity and safety in mild COVID-19 patients. Imusil ensures faster RT-PCR negativity and clinical improvement and ensures effective reduction of inflammatory markers such as CRP, D-dimer and interleukin 6.

Abstract
In the current scenario, most countries are affected by COVID-19, a pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has a massive impact on human health. Previous studies showed that some traditionally used medicinal herbs and their combinations showed synergistic anti-viral and anti-inflammatory activity against SARS-CoV-2 type infections. Therefore, the goal of this study is to demonstrate the anti-viral and anti-inflammatory effects of a novel polyherbal formulation, hereinafter referred to as Imusil, on Vero E6 cell lines and Raw 264.7 murine macrophage cells respectively. The Imusil was subjected to identify its chemical characterisations such as UV–Visible spectrum profile, Fourier transform infrared spectroscopy (FT-IR) and gas chromatography–mass spectroscopic (GC–MS) analysis. FT-IR analysis of Imusil peak values with various functional compounds such as alcohol, esters, aliphatic and carboxylic acids. GC–MS analysis of compounds with totally 87 compounds major chemical compounds were identified, such as 3-(Octanoyloxy) propane-1,2-diyl bis(decanoate), Succinic acid, 2-methylhex-3-yl 2,2,2-trifluoroethyl ester, Neophytadiene, 3,5,9-Trioxa-4-phosphaheneicosan-1-aminium, 4-hydroxy-N,N,N-trimethyl-10-oxo-7-[(1-oxododecyl)oxy]-, hydroxide, inner salt, 4-oxide, (R)-. The anti-viral activity of Imusil against SARS-CoV-2 was assessed using plaque reduction assay and anti-inflammatory study was conducted on lipopolysaccharide (LPS)-induced RAW 264.7 cells. The results obtained from the study reveal that Imusil significantly inhibited SARS-CoV-2 replication in Vero E6 cells and the production of inflammatory mediator’s cyclooxygenase-2 and pro-inflammatory cytokines like tumour necrosis factor-α and interleukin- 6 were significantly reduced, along with thwarting the significant oxidative stress by preventing the expression of NOX-2 thereby inhibiting the reactive oxygen species formation. Hence, considering the current study as a novel strategy for mediating the COVID-19 associated aliments, inceptive scientific evidence of Imusil promises its potential therapeutic implications against COVID-19 and inflammatory conditions.

Abstract
Oxidised low-density lipoprotein (ox-LDL) is a pro-atherogenic molecule, which induces inflammatory response and contributes to the pathogenesis of vascular dysfunction to atherosclerosis. The aim of the present study was to explore the anti-inflammatory effect of a novel bioavailable formulation of curcumin as 'curcumagalactomannosides' (CGM) against ox-LDL-induced inflammatory responses in human peripheral blood mononuclear cells (hPBMCs). Curcumagalactomannosides was made from natural curcumin using the soluble dietary fibre (galactomannans) derived from fenugreek seeds (Trigonella foenumgracum) and the hPBMCs were isolated from healthy human volunteers. The cells were cultured in collagen-coated plates at 37 °C and grouped as Group I (Control), Group II (ox-LDL treated) and Group III (ox-LDL + CGM treated). Further analysis of inflammatory markers, reactive oxygen species and mRNA expression levels indicated significantly increased expressions of iNOS, TNF-α, IL-6 and VCAM-1 in ox-LDL-treated group along with the nuclear translocation of NF-κB. Other inflammatory markers such as LOX, PGE2, total COX and lipid peroxidation level were also found to be significantly (p < 0.05) increased upon ox-LDL treatment. The treatment with CGM on the other hand was found to down-regulate and reverse the ox-LDL-induced alterations indicating its potential anti-inflammatory effect on hPBMCs via. NF-κB signalling pathway.

Abstract
We evaluated the protective efficacy of the polyphenolic fraction from virgin coconut oil (PV) against adjuvant induced arthritic rats. Arthritis was induced by intradermal injection of complete Freund's adjuvant. The activities of inflammatory, antioxidant enzymes and lipid peroxidation were estimated. PV showed high percentage of edema inhibition at a dose of 80mg/kg on 21st day of adjuvant arthritis and is non toxic. The expression of inflammatory genes such as COX-2, iNOS, TNF-α and IL-6 and the concentration of thiobarbituric acid reactive substance were decreased by treatment with PV. Antioxidant enzymes were increased and on treatment with PV. The increased level of total WBC count and C-reactive protein in the arthritic animals was reduced in PV treated rats. Synovial cytology showed that inflammatory cells and reactive mesothelial cells were suppressed by PV. Histopathology of paw tissue showed less edema formation and cellular infiltration on supplementation with PV. Thus the results demonstrated the potential beneficiary effect of PV on adjuvant induced arthritis in rats and the mechanism behind this action is due to its antioxidant and anti-inflammatory effects.

Abstract
CONTEXT The anti-atherogenic effect of alkaloid fraction from Ruta graveolens Linn (Rutaceae) extract is suspected to be related to its activities of antioxidation and anti-inflammation. OBJECTIVE This study investigated the efficacy of alkaloid fraction isolated from Ruta graveolens (AFR) in reducing oxidative damage and inflammation in hypercholesteremic rabbits. MATERIALS AND METHODS The New Zealand white rabbits were randomly divided into three groups: Group I rabbits were fed with normal chow diet for 90 d. Group II rabbits were fed with 1% cholesterol-enriched diet. Group III rabbits were fed with 1% cholesterol-enriched diet together with AFR (10 mg/kg/daily for 90 d). RESULTS AND DISCUSSION The results showed that on treatment with AFR significantly lowered the level of total cholesterol and LDL-C and showed an increment in the level of HDL-C. LD50 of the AFR in rats is greater than 525 mg/kg. Activities of antioxidant enzymes such as superoxide dismutase, catalase and glutathione peroxidase and GSH level were decreased in cholesterol-fed rabbit and supplementation of AFR significantly enhanced the activities of these antioxidant enzymes and GSH level. Increased activities of enzymes such as cyclooxygenase-2, 15-lipoxygenase and myeloperoxidase were significantly suppressed by AFR administration. The acute phase proteins, total WBC count and TBARS concentrations were significantly increased by hypercholesteromic diet, which were significantly decreased by AFR treatment. Histopathological studies of aorta in cholesterol-fed rabbit showed plaque formation and significant changes in aortic wall. Administration of AFR showed no changes in aortic wall. CONCLUSION AFR reduces oxidative stress and inflammation and reduces the aortic pathology in hypercholesteromic rabbits.

Abstract
The aim of this study was to investigate anti-inflammatory and antioxidant effects of mucilage from fenugreek in adjuvant induced arthritis in rats. Arthritis was induced by intradermal injection of complete Freund's adjuvant into the right hind paw produce inflammation of the joint. The activities of inflammatory enzymes like cyclooxygenase, lipoxygenase and myeloperoxidase, and levels of nitrite and C-reactive protein were observed. Also oxidative stress was measured by analyzing the activity of catalase, superoxide dismutase, glutathione peroxidase and the levels of glutathione and vitamin C and lipid peroxidation. The blood parameters like ESR, total WBC, RBC and hemoglobin content was checked. Fenugreek mucilage exhibited maximum percentage of edema inhibition at a dose of 75 mg/kg on 21st day of adjuvant arthritis. The effect was higher than that of standard drug indomethacin. The activities of cyclooxygenase-2 and myeloperoxidase and concentration of thiobarbituric acid reactive substance (TBARS) were decreased and the activities of antioxidant enzymes, vitamins C and reduced glutathione level were increased on treatment with fenugreek mucilage. The increment in ESR and total WBC, reduction in RBC count and hemoglobin and aberrant changes to the C-reactive protein (CRP) levels observed in the arthritic animals were also found to be significantly restored in fenugreek mucilage treated rats. Histopathology of paw tissue showed decreased edema formation and cellular infiltration on supplementation with fenugreek mucilage. Thus the results demonstrated the potential beneficiary effect of fenugreek mucilage on adjuvant induced arthritis in rats.

Abstract
The purpose of this study was to investigate the anti-inflammatory function and mechanism(s) of action of an active component-betulinic acid isolated from Bacopa monniera. Betulinic acid, a pentacyclic triterpenoid markedly suppressed lipopolysaccharide (LPS) induced IL-6 production in blood mononuclear cells both in vivo and in vitro. Betulinic acid also prevented LPS induced nuclear translocation of p65 NF-kappaB in hPBMCs. LPS induced nuclear translocation of NF-kappaB and IL-6 production was also abolished by p38 and ERK MAPK inhibitors PD98059 and SB203580. Addition of each of these inhibitors to cell cultures along with betulinic acid caused significant downregulation of IL-6 production and inhibition of p65 NF-kappaB nuclear translocation. The inhibitory effect of both betulinic acid and the inhibitors was higher than that of cells treated with inhibitors alone. These results suggest that betulinic acid inhibited IL-6 production by preventing p65 NF-kappaB nuclear translocation and there is a possibility that this prevention of p65 nuclear translocation may involve p38 and ERK MAPKs as cross talks occur between MAPK and NF-kappaB pathways. This study provides an insight into the probable mechanism(s) underlying the anti-inflammatory and therapeutic properties of betulinic acid.

Abstract
The present study was aimed to establish the efficacy of Jeevaneeya Rasayana (JR), an ayurvedic polyherbal formulation, in adjuvant-induced arthritic (AIA) rat model with reference to mediators of inflammation. The methanolic (MJR), ethanolic (EJR), and water extracts (WJR) of JR were prepared and their anti-inflammatory activity in carrageenan-induced acute model was evaluated. MJR at a dose of 25 mg/kg showed significantly higher anti-inflammatory effect than EJR, WJR, and standard drug diclofenac. MJR also significantly decreased the paw edema in AIA rats. Activities of cyclooxygenase, 5-lipoxygenase, and myeloperoxidase were decreased significantly on treatment with MJR. Supplementation with MJR increases the activities of antioxidant enzymes and the level of glutathione content. The increment in the concentration of C-reactive protein, thiobarbituric acid reactive substance, and ceruloplasmin observed in arthritic rats were found to be significantly restored in MJR treated rats. Thus, the results demonstrated the potential beneficiary effect of methanolic extract of Jeevaneeya Rasayana on acute and chronic models of inflammation.
