Beigoli S, Boskabady MH. The molecular basis of the immunomodulatory effects of natural products: A comprehensive review. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 135:156028. [PMID: 39276685 DOI: 10.1016/j.phymed.2024.156028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 07/21/2024] [Accepted: 09/02/2024] [Indexed: 09/17/2024]
Abstract
BACKGROUND Natural products (NPs) have long been recognized for their potential to modulate the immune system, offering a natural and holistic approach to enhancing immune function. In recent years, the immunomodulation effects of various natural products have attained significant attention. PURPOSE This article provides an overview of the role of natural products in immunomodulation, exploring their mechanisms of action, common types of NPs with immunomodulation properties, clinical applications, as well as considerations for their safety and efficacy. METHODS Extensive research has been conducted to compile important discoveries on the immunomodulatory properties of NPs through thorough searches of multiple databases such as PubMed, Science Direct, and Scopus up until January 2024. RESULTS By decreasing the levels of Th2 cytokines and pro-inflammatory cytokines, the results suggested that NPs have the ability to modulate the immune system. Therefore, NPs alleviate inflammation in various disorders such as asthma and cancer. Furthermore, the observed increase in CD4 cells and IFN-ɣ/IL4 levels, along with an increased IFN-c/IL4 ratio, indicates a stimulatory effect of NPs on Th1 activity in various inflammatory conditions. Therefore, NPs regulate the immune system by inhibiting T-cells and decreasing the growth of young B-cell lymphoma cells. CONCLUSION Reviewing studies indicated that NPs have the potential to serve as immunomodulatory candidates for treating disorders characterized by immune dysregulation. However, additional experimental and clinical studies are necessary before these agents can be implemented in clinical settings.

Rashid M, Rashid R, Saroya S, Deverapalli M, Brim H, Ashktorab H. Saffron as a Promising Therapy for Inflammatory Bowel Disease. Nutrients 2024; 16:2353. [PMID: 39064796 PMCID: PMC11280066 DOI: 10.3390/nu16142353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Revised: 07/15/2024] [Accepted: 07/16/2024] [Indexed: 07/28/2024] Open
Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory illness of the gastrointestinal tract (GI), characterized by recurrent episodes of inflammation and tissue destruction. It affects an increasing number of individuals worldwide who suffer from Crohn's disease (CD) or ulcerative colitis (UC). Despite substantial advances in understanding the underlying causes of IBD, the available treatments remain restricted and are sometimes accompanied by severe consequences. Consequently, there is an urgent need to study alternate therapeutic options. This review assesses the present drugs, identifies their limitations, and proposes the use of saffron, a natural plant with great therapeutic potential based on preclinical and clinical investigations. Saffron has gained attention for its potential therapeutic benefits in treating various ailments due to its established bioactive compounds possessing antioxidant and anti-inflammatory properties. This review covers how saffron impacts the levels of calprotectin, an inflammatory marker, for various inflammatory responses in multiple diseases including IBD. Data from clinical trials were assessed to determine the efficacy and safety of using saffron to counter inflammation in multiple diseases. Studies have shown that saffron may protect against inflammatory bowel disease (IBD) through several mechanisms by inhibiting pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6), reducing oxidative stress through antioxidant effects, enhancing mucosal barrier function by upregulating tight junction proteins, and modulating the gut microbiota composition to promote beneficial bacteria while suppressing pathogenic ones; these combined actions contribute to its therapeutic potential in managing and alleviating the symptoms of IBD. This will enable future research endeavors and expedite the translation of saffron-based interventions into clinical practice as a valuable adjunctive therapy or a potential alternative to conventional treatments, thereby enhancing the quality of life for individuals suffering from inflammatory diseases including IBD.

Abstract
The effect of Crocus sativus on several disorders has been discussed or even confirmed, but the efficacy of this herb on the female reproductive system has not been well presented. In this regard, this systematic review comprehensively discussed the efficacy of C. sativus and its main phytochemical compounds on the female reproductive system and its disorders for the first time. In this systematic review, scientific databases, including PubMed, Web of Sciences, Google Scholar, Scopus, and Scientific Information Database, were explored profoundly. In vivo, in vitro, and human studies published until the end of July 2023, which had investigated the pharmacological properties of C. sativus, crocin, crocetin, safranal, or picrocrocin on the female reproductive system, were selected. A total of 50 studies conducted on the effect of C. sativus on the female reproductive system were acquired. These studies confirmed the efficacy of C. sativus or its main phytochemical ingredients in several aspects of the female reproductive system, including regulation of sex hormones, folliculogenesis, ovulation, and protection of the ovary and uterus against several oxidative stress. Several retrieved studies indicated that this herb also can alleviate the symptoms of patients suffering from dysmenorrhea, premenstrual syndrome, menopause, polycystic ovary disease (PCOD), and sexual dysfunction. Furthermore, it is a promising candidate for future studies or even trials regarding ovarian and cervical cancers. This review concluded that C. sativus can improve the symptoms of several female reproductive system disorders, which is particularly due to the presence of phytochemical ingredients, such as crocin, crocetin, and safranal.

Abstract
BACKGROUND The pathogenesis of COVID-19 includes an integrated immune-inflammatory response. Modulation of host immune responses against the SARS-CoV-2 virus might be effective therapeutic management. Various Unani formulations have an immunomodulatory effect. OBJECTIVE To explore the immunomodulatory effect and safety of Unani polyherbal drug (Tiryaq Wabai) in COVID-19 patients. MATERIALS AND METHODS The current study was a randomized placebo-controlled clinical trial that included 92 mild to moderate COVID-19 patients randomized into two groups. The Unani formulation Tiryaq Wabai (2 gm orally once a day) was used as an intervention for 45 days, while the control group received a placebo. Both groups received standard care treatment. The primary outcome was 50% increment in absolute lymphocyte count (ALC). The secondary outcome was 50% increment in mean lymphocyte percentage, CD4 cells, and CD8 cell count. The mean increase in all the above parameters has also been studied. Relevant statistical tests were used to analyze the effect. RESULTS A statistically significant improvement in a 50% increase in ALC (p-value, 0.004), lymphocyte percentage (p-value, 0.056), CD4 (p-value, 0.005), and CD8 cell count (p-value, 0.050) was reported. Also, a significant improvement in the mean value of the lymphocyte percentage (p-value 0.0007), ALC (p-value 0.0022), CD4 cell count (p-value 0.0025), and CD8 cell count (p-value 0.0093) was observed after the treatment. One adverse event of mild grade was reported in the placebo group. The analysis of safety parameters (LFT and KFT) was normal for both groups. CONCLUSION In mild to moderate COVID-19 patients, Tiryaq Wabai effectively showed immunomodulatory activity by improving ALC count, lymphocyte percentage, CD4, and CD8 cell count.

Abstract
Introduction COVID-19 has affected the whole world drastically and led to a substantial loss of human life. Relentless research is underway to identify effective treatment to control the disease. Traditional systems are also being explored to search for a potent drug. Unani formulation 'Tiryāq-i-Wabāī' has long been used in cholera, plague and other epidemic diseases. This review is aimed at analysing the possible role of Tiryāq-i-Wabāī in the prevention and control of COVID-19. Methodology Unani classical texts and Pharmacopoeias available in the library of Regional Research Institute of Unani Medicine, Chennai were reviewed to collect information related to epidemics, commonly prescribed drugs during epidemics, and therapeutic uses of Tiryāq-i-Wabāī ingredients. ScienceDirect, Springer, PubMed and Google Scholar were searched to collect information regarding current pandemic and pharmacological activities of ingredients and phytoconstituents present in the formulation. The collected data was analyzed and interpreted. Results Tiryāq-i-Wabāī was found to be the most recommended prophylactic and curative drug during epidemics. The formulation ingredients, Sibr (Aloe vera (L.) Burm.f.), Murr Makki (Commiphora myrrha (T.Nees) Engl.) and Zāfrān (Crocus sativus L.) are categorized under Tiryāqi Advia (literally - antidote drugs) and are considered to be very effective in SARS related conditions. These ingredients have been reported to exhibit immunomodulatory, antioxidant, antiviral, antibacterial, antitussive, smooth muscle relaxant, antipyretic and anti-inflammatory activities corroborating the traditional use of Tiryāq-i-Wabāī. Conclusion Scientific data imply great potential and utility of the formulation which could be a possible alternative approach for the prevention and control of current and future pandemics.

Abstract
CONTEXT Saffron (Crocus sativus L.) has been proposed as a potential agent to improve renal function in animal studies. But, due to insufficient evidence in human research, further investigation is needed. OBJECTIVE To fill this knowledge gap, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the effect of saffron supplementation on the measures of renal function indicators in adults. Renal function was assessed based on serum urea, blood urea nitrogen, and creatinine levels. METHOD AND MATERIALS A systematic search in PubMed/Medline, Scopus, Web of Science, Embase, and Google Scholar databases was done until March 2021 using relevant keywords. A random-effects model was used to estimate the weighted mean difference (WMD) and 95% confidence (95% CI). Nine RCTs were included in the meta-analysis, and their quality was assessed using the Cochrane risk of bias tool. RESULTS The pooled analysis showed that saffron supplementation had no significant effect on serum urea concentrations (WMD: - 1.05 mg/dl; 95% CI - 5.1 to 3; P = 0.6, I2 = 93%, P < 0.001) and serum creatinine levels (WMD: - 0.006 mg/dl; 95% CI - 0.08 to 0.06; P = 0.8, I2 = 79%, P < 0.001) when compared to the placebo group. In the dose-response analysis, we observed a significant non-linear relationship between the duration of saffron supplementation and serum urea and creatinine levels. CONCLUSIONS Based on our findings, Saffron supplementation had no significant effect on renal function markers, including urea and creatinine. However, further trials are required to determine the actual effect and safety of saffron intervention in human studies. PROSPERO SUBMISSION ID 248081.

Abstract
BACKGROUND Many Ayurvedic preparations are claimed to have immune-boosting properties, as suggested in various published randomized clinical trials (RCTs). AIM To compile evidence on the nature and mechanism of immune system enhancement by Ayurvedic preparations in healthy and sick individuals. METHODS After prospectively registering study protocol with PROSPERO, we searched PubMed, DOAJ, Google Scholar, three dedicated Ayurveda research portals, two specialty Ayurveda journals, and reference lists for relevant records published until February 6, 2021 using appropriate search strategies. Baseline features and data pertaining to the nature and mechanism of immune system function were extracted from all eligible records. Methodological quality was assessed using the Cochrane RoB-2 tool. RESULTS Of 12554 articles screened, 19 studies reporting 20 RCTs (17 parallel group design, three crossover design) with 1661 unique patients were included; 11/19 studies had Indian first authors. Healthy population was included in nine studies, of which one study included pregnant women and two included pediatric population; remaining studies included patients with different health conditions, including one study with coronavirus disease 2019 patients. A total of 21 Ayurvedic interventions were studied, out of which five were composite mixtures. The predominant route of administration was oral; dose and frequency of administration of the intervention varied across the studies. The results reported with five RCTs exploring five Ayurvedic interventions were incomplete, ambiguous, or confusing. Of the remaining 16 interventions, indirect evidence of immune enhancement was reported with four interventions, while lack of the same was reported with two interventions. Enhancement of T helper cells and natural killer cells was reported with three and four interventions, respectively, while the pooled results did not clearly point toward enhancement of other components of the immune system, including cytotoxic T cells, B lymphocytes, immunoglobulins, cytokines, complement components, leucocyte counts, and other components. Nine of the 20 RCTs had a high risk of bias, and the remaining 11 RCTs had some concerns according to RoB-2. CONCLUSION Various Ayurvedic preparations appear to enhance the immune system, particularly via enhancements in natural killer cells and T helper cells.

Abstract
Attention deficit hyperactivity disorder (ADHD) is commonly a neurodevelopmental behavioural disorder in children and adolescents. Mainly characterized by symptoms like lack of attention, hyperactivity, and impulsiveness, it can impact the overall mental development of the one affected. Several factors, both genetic and non-genetic, can be responsible for this disorder. Although several traditional treatment methods involve medication and other counselling techniques, they also come with different side effects. Hence, the choice is now shifting to alternative treatment techniques. Herbal treatments are considered one of the most popular complementary and alternative medicine (CAM) administered. However, issues related to the safety and efficacy of herbal remedies for the treatment of ADHD need to be investigated further. This study aims to find out the recent advancement in evidence-based use of herbal remedies for ADHD by a comprehensive and systematic review that depicts the results of the published works on herbal therapy for the disorder. The electronic databases and the references retrieved from the included studies present related randomized controlled trials (RCTs) and open-label studies. Seven RCTs involving children and adolescents diagnosed with ADHD met the inclusion criteria. There is a fair indication of the efficacy and safety of Melissa officinalis L., Bacopa monnieri (L.) Wettst., Matricaria chamomilla L., and Valeriana officinalis L. from the studies evaluated in this systematic review for the treatment of various symptoms of ADHD. Limited evidence was found for Ginkgo biloba L. and pine bark extract. However, various other preparations from other plants did not show significant efficacy. There is inadequate proof to strongly support and recommend the administration of herbal medicines for ADHD, but more research is needed in the relevant field to popularize the alternative treatment approach.

Abstract
BACKGROUND The present systematic review and meta-analysis of randomized controlled trials (RCTs) aimed at determining the effect of saffron supplementation on renal function. METHODS Electronic databases were searched up to February 2021. The risk of bias in individual studies was assessed using the Cochrane Collaboration tool. The overall weighted mean difference (WMD) and their 95% confidence intervals (CIs) were calculated using random-effect models. P < 0.05 was considered statistically significant. RESULTS A total of 11 trials were included in this study. Saffron had beneficial effect on BUN (WMD = -0.69 mg/dl; 95% CI, -1.36 to -0.01; P=0.046) compared to placebo, with significant heterogeneity (I 2 = 49.6%, P=0.037). However, it had no significant effect on serum Cr (WMD = 0.04 mg/dl; 95% CI: -0.01 to 0.09; P=0.127). CONCLUSION It seems that saffron supplementation had no significant effect on Cr as a renal function factor. However, BUN reduction was significant in the saffron group compared to placebo.

Abstract
BACKGROUND AND AIMS Possible protective effects of saffron (Crocus sativus L) have been reported in several randomized clinical trials (RCTs). Current systematic review was performed to summarize the efficacy of saffron intake on liver enzymes. METHODS An electronic database search was conducted on PubMed/Medline, Scopus, Web of Science, and Cochrane for RCTs comparing effect of saffron and placebo on liver enzymes from inception to July 2021. There was no restriction in language of included studies and we calculated the standardized mean difference (SMD) and 95% Confidence Intervals (CI) for each variable. Random-effect model was used to calculate effect size. RESULTS Eight studies (n = 463 participants) were included in the systematic review. The saffron intake was associated with a statistically significant decrease in aspartate aminotransferase (AST) (SMD: -0.18; 95% CI: -0.34, -0.02; I2 = 0%) in comparison to placebo intake. Our results also indicated that saffron consumption did not have a significant effect on alanine aminotransferase (ALT) (SMD: -0.14; 95% CI: -0.36, 0.09; I2 = 47.0%) and alkaline phosphatase (ALP) levels (SMD: 0.14; 95% CI: -0.18, 0.46; I2 = 42.9%) compared to placebo. CONCLUSIONS Saffron intake showed beneficial impacts on circulating AST levels. However, larger well-designed RCTs are still needed to clarify the effect of saffron intake on these and other liver enzymes.

Abstract
Crocus sativus Linn. (Saffron) is valued worldwide for its potential use in the management of various degenerative disorders, including cardiovascular diseases (CVDs), diabetes, cancer, metabolic syndrome (MetS), neurodegenerative diseases, immune disorders, and sexual dysfunction. Previous reports, based on clinical trials, suggest that crocetin, crocin, picrocrocin, and safranal are the main bioactive components of saffron with antioxidant, anti-inflammatory, and anti-apoptotic effects. In this comprehensive narrative review, we studied the recent clinical trials, investigating the medicinal applications of saffron and/or its components. The present results can provide important insights into the potential of saffron in preventing and treating different disorders, with a special focus on the underlying cellular and molecular mechanisms. However, further high-quality studies are needed to firmly establish the clinical efficacy of saffron in treating some degenerative diseases.

Abstract
BACKGROUND Abdominal adhesions are common and often develop after abdominal surgery. There are currently no useful targeted pharmacotherapies for adhesive disease. Saffron and its active constituents, Crocin and Crocetin, are wildly used in traditional medicine for alleviating the severity of inflammatory or malignant disease. PURPOSE The aim of this study was to investigate the therapeutic potential of the pharmacological active component of saffron in attenuating the formation of post-operative adhesion bands using different administration methods in a murine model. MATERIAL METHOD saffron extract (100 mg/kg), Crocin (100 mg/kg), and Crocetin (100 mg/kg) were administered intraperitoneally and by gavage in various groups of male Wistar rat post-surgery. Also three groups were first treated intra-peritoneally by saffron extract, Crocin, and Crocetin (100 mg/kg) for 10 days and then had surgery. At the end of the experiments, animals sacrificed for biological assessment. RESULT A hydro-alcoholic extract of saffron and crocin but not crocetin potently reduced the adhesion band frequency in treatment and pre-treatment groups in the mice given intra-peritoneal (i.p) injections. Following the saffron or crocin administration, histological evaluation and quantitative analysis represented less inflammatory cell infiltration and less collagen composition, compared to control group. Moreover, the oxidative stress was significantly reduced in treatment groups. CONCLUSION These findings suggest that a hydro-alcoholic extract of saffron or its active compound, crocin, is a potentially novel therapeutic strategy for the prevention of adhesions formation and might be used as beneficial anti-inflammatory or anti-fibrosis agents in clinical trials. TAXONOMY Abdominal surgeries/post-surgical adhesions.

Abstract
The effects of saffron (Crocus sativus L.) on mood disorders have already been established. More recently, its anti-neoplastic effects have provoked a great attention. This study aims to assess the effects of crocin administration during doxorubicin-based chemotherapy of breast cancer on anxiety, depression, and chemotherapy toxicity profile. Seventy-two patients with non-metastatic Her2/neu positive or triple negative breast cancer were enrolled and randomly assigned to receive either 30 mg/day of crocin or placebo during chemotherapy [2:2]. Beck's Depression and Anxiety Inventories were used at baseline and end of the trial. In addition, the ECOG Common Toxicity Criteria were applied to assess chemotherapy side-effects. After the intervention, the degree of anxiety and depression decreased significantly in the crocin group (p = .001 for both) and increased significantly in the placebo-group (p = .006 and p = .036, respectively). There were significantly higher grade II-IV leukopenia (47.2% vs. 19.4%, p = .012) in the crocin group, and grade II-IV hypersensitivity-reaction (30.6% vs. 5.6%, p = .006) in addition to neurological disorders (66.7% vs. 41.7%, p = .03) in the placebo-group. The results indicate that using crocin during chemotherapy in patients with breast cancer has ameliorated anxiety and depression. Moreover, leucopenia increased whereas hypersensitivity reaction and neurological disorders decreased in the crocin group. In addition, a trend toward survival improvement was observed, which is going to be investigated on longer follow up.

Abstract
Edible flowers are attracting special therapeutic attention and their administration is on the rise. Edible flowers play pivotal modulatory roles on oxidative stress and related interconnected apoptotic/inflammatory pathways toward the treatment of cancer. In this review, we highlighted the phytochemical content and therapeutic applications of edible flowers, as well as their modulatory potential on the oxidative stress pathways and apoptotic/inflammatory mediators, resulting in anticancer effects. Edible flowers are promising sources of phytochemicals (e.g., phenolic compounds, carotenoids, terpenoids) with several therapeutic effects. They possess anti-inflammatory, anti-diabetic, anti-microbial, anti-depressant, anxiolytic, anti-obesity, cardioprotective, and neuroprotective effects. Edible flowers potentially modulate oxidative stress by targeting erythroid nuclear transcription factor-2/extracellular signal-regulated kinase/mitogen-activated protein kinase (Nrf2/ERK/MAPK), reactive oxygen species (ROS), nitric oxide (NO), malondialdehyde (MDA) and antioxidant response elements (AREs). As the interconnected pathways to oxidative stress, inflammatory mediators, including tumor necrosis factor (TNF)-α, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), interleukins (ILs) as well as apoptotic pathways such as Bcl-2-associated X protein (Bax), Bcl-2, caspase and cytochrome C are critical targets of edible flowers in combating cancer. In this regard, edible flowers could play promising anticancer effects by targeting oxidative stress and downstream dysregulated pathways.

Abstract
The present article reviews and compares the immunomodulatory activities of Crocus sativus (C. sativus) and Nigella sativa (N. sativa) and their main bioactive compounds. Immunomodulatory effects of these plants, especially with respect to Th1 and Th2 cytokines, are discussed based on relevant articles, books, and conference papers published in English until the end of April 2020, that were retrieved from Web of Science, PubMed, Scopus and Google Scholar databases. C. sativus and its constituents increase immunoglobulin (Ig-)G, interleukin 2 (IL)-2, interferon gamma (IFN-γ), and IFN-γ/IL-4 ratio, but decreased IgM, IL-10 and IL-4 secretion. N. sativa extract and thymoquinone reduce the levels of IL-2, -4, -10, and -12, while enhance IFN-γ and serum IgG1 and 2a. The reviewed articles indicate that C. sativus and N. sativa and their constituents could be potentially considered promising treatments for disorders associated with immune-dysregulation such as asthma and cancer.

Abstract
Severe acute respiratory syndrome coronavirus 2, SARS-CoV-2 (COVID-19), came as a significant health care challenge for humans in 2019-20. Based on recent laboratory and epidemiological studies, a growing list of mutations in the virus has the potential to enhance its transmission or help it evade the immune response. To further compound the problems, there are considerable challenges to the availability of effective, affordable, safe vaccines on a mass scale. These impediments have led some to explore additional options available in traditional medicines, especially immune-boosting natural products. Saffron has been used for centuries to treat fever, bronchitis, cold and other immune, respiratory disorders. Herein, we discuss the potential role of saffron during and after COVID-19 infection, focusing on immunomodulation, respiratory, renal, and cardiovascular functions. As a nutraceutical or drug supplement, it can alleviate the magnitude of COVID-19 symptoms in patients. The anti-inflammatory, antioxidant, and other medicinal properties attributed to saffron bioactive compounds can help in both pre-and post-infection management strategies. The abnormalities associated with COVID-19 survivors include anxiety, depression, sleep disturbances, and post-traumatic stress disorder. Saffron can help manage these post-hospitalization abnormalities (sub-acute and chronic) too, owing to its anti-depressant property. It can help common people boost immunity and manage depression, stress and anxiety caused due to prolonged lockdown, isolation or quarantine.

Abstract
Background An up-to-date overview of determinants of serum immunoglobulins in adults is pivotal for clinical practice and research, but currently lacking. We therefore performed a systematic review and meta-analysis to identify determinants of serum immunoglobulin levels. Methods Embase, Web of Science, Medline, Cochrane, and Google Scholar were searched from inception to July 11th, 2019 for articles reporting on determinants of serum immunoglobulin A, G or M (IgA, IgG or IgM) in adult humans. Random and fixed effect models were applied to obtain pooled mean differences (MDs) and 95% confidence intervals (CIs) for the association of age and sex with serum immunoglobulins. Results We retrieved 117 articles reporting on determinants of serum immunoglobulins, of which 28 could be meta-analyzed. Older compared to younger individuals had higher IgA (MD: 0.38; CI: 0.18 - 0.58), but lower IgM levels (MD: -0.40; 95%: -0.66 - -0.14). Men had higher IgA (MD: 0.22; CI: 0.03 - 0.42), but lower IgM levels (MD: -0.21; CI: -0.32 - -0.10) than women. Age and sex did not influence IgG. Caucasian ethnicity was associated with lower IgA, IgG, and IgM. Smoking and corticosteroid use were associated with lower IgG. Positive associations were reported of probiotics with IgG, alcohol with IgA, hypertension with IgA and IgG, and acute psychological stress with IgA, IgG, and IgM. Conclusions Older age and male sex are associated with higher IgA, but lower IgM, and urge investigation of age- and sex-specific reference ranges of immunoglobulins. Other identified determinants were ethnicity, diet, lifestyle and cardio-metabolic factors.

Abstract
BACKGROUND AND AIMS The present systematic review and meta-analysis of randomized controlled trials aimed to determine the effects of saffron supplementation on liver function tests among adults. METHODS Electronic databases including PubMed, ISI Web of Science, and Scopus were searched up to January 2021. The risk of bias in individual studies was assessed using the Cochrane Collaboration tool. The overall estimates and their 95% CIs were calculated using random-effects models. Egger's test and Begg's rank-correlation were run to assess the presence of publication bias. p < 0.05 was considered statistically significant. RESULTS A total of 12 trials involving 608 participants were included in this systematic review and meta-analysis. Saffron supplementation had no significant effect on liver function tests including aspartate transaminase (AST) (weighted mean difference [WMD] = 0.23 U/L; 95% CI -2.22 to 2.69; p = 0.851; I2 = 74.0%), alanine aminotransferase (ALT) (WMD = -1.49 U/L; 95% CI -3.84 to 0.86; p = 0.213; I2 = 60.2%), and alkaline phosphatase (ALP) (WMD = -0.70 U/L; 95% CI -11.35 to 9.95; p = 0.898; I2 = 40.8%) compared to placebo. CONCLUSION Based on what was discussed, it seems that saffron supplementation could not improve liver function tests including AST, ALT, and ALP among the adult population. Further clinical trials with larger sample size, longer duration, and higher doses of saffron should be conducted exclusively among patients with liver dysfunction to elucidate the beneficial role of saffron consumption on liver function.

Abstract
Saffron (Crocus sativus L.) is an important plant in medicine. The Kashmir Valley (J&K, India) is one of the world's largest and finest saffron producing regions. However, over the past decade, there has been a strong declining trend in saffron production in this area. Plant Growth Promoting Rhizobacteria (PGPR) are free living soil bacteria that have ability to colonize the surfaces of the roots and ability to boost plant growth and development either directly or indirectly. Using the efficient PGPR as a bio-inoculant is another sustainable agricultural practice to improve soil health, grain yield quality, and biodiversity conservation. In the present study, a total of 13 bacterial strains were isolated from rhizospheric soil of saffron during the flowering stage of the tubers and were evaluated for various plant growth promoting characteristics under in vitro conditions such as the solubilization of phosphate, production of indole acetic acid, siderophore, hydrocyanic acid, and ammonia production and antagonism by dual culture test against Sclerotium rolfsii and Fusarium oxysporum. All the isolates were further tested for the production of hydrolytic enzymes such as protease, lipase, amylase, cellulase, and chitinase. The maximum proportions of bacterial isolates were gram-negative bacilli. About 77% of the bacterial isolates showed IAA production, 46% exhibited phosphate solubilization, 46% siderophore, 61% HCN, 100% ammonia production, 69% isolates showed protease activity, 62% lipase, 46% amylase, 85% cellulase, and 39% showed chitinase activity. Three isolates viz., AIS-3, AIS-8 and AIS-10 were found to have the most plant growth properties and effectively control the growth of Sclerotium rolfsii and Fusarium oxysporum. The bacterial isolates were identified as Brevibacterium frigoritolerans (AIS-3), Alcaligenes faecalis subsp. Phenolicus (AIS-8) and Bacillus aryabhattai (AIS-10) respectively by 16S rRNA sequence analysis. Therefore, these isolated rhizobacterial strains could be a promising source of plant growth stimulants to increase cormlets growth and increase saffron production.

Abstract
A new coronavirus causing severe acute respiratory syndrome (SARS-CoV-2) has emerged and with it, a global investigation of new antiviral treatments and supportive care for organ failure due to this life-threatening viral infection. Traditional Persian Medicine (TPM) is one of the most ancient medical doctrines mostly known with the manuscripts of Avicenna and Rhazes. In this paper, we first introduce a series of medicinal plants that would potentially be beneficial in treating SARS-CoV-2 infection according to TPM textbooks. Then, we review medicinal plants based on the pharmacological studies obtained from electronic databases and discuss their mechanism of action in SARS-CoV-2 infection. There are several medicinal plants in TPM with cardiotonic, kidney tonic, and pulmonary tonic activities, protecting the lung, heart, and kidney, the three main vulnerable organs in SARS-CoV-2 infection. Some medicinal plants can prevent "humor infection", a situation described in TPM which has similar features to SARS-CoV-2 infection. Pharmacological evaluations are in line with the therapeutic activities of several plants mentioned in TPM, mostly through antiviral, cytoprotective, anti-inflammatory, antioxidant, and anti-apoptotic mechanisms. Amongst the primarily-introduced medicinal plants from TPM, rhubarb, licorice, garlic, saffron, galangal, and clove are the most studied plants and represent candidates for clinical studies. The antiviral compounds isolated from these plants provide novel molecular structures to design new semisynthetic antiviral agents. Future clinical studies in healthy volunteers as well as patients suffering from pulmonary infections are necessary to confirm the safety and efficacy of these plants as complementary and integrative interventions in SARS-CoV-2 infection.

Abstract
OBJECTIVE Saffron as a natural product has long been used to impede and treat different disorders including cardiovascular disease (CVDs). Stigma is the most principal part of saffron. Various compounds such as carotenoids and flavonoids are the essential components of saffron stigma. The health benefits of saffron have been shown in previous studies; however, there is a lack of comprehensive data on the mechanistic aspects of its cardiovascular-health properties. This current comprehensive review focuses on the medicinal applications of saffron, and then the new findings regarding its cardiovascular-health effects and various cellular and molecular mechanisms of action will be debated. METHODS The literature search of MEDLINE, Embase, PubMed, Google Scholar and Cochrane Library was performed for all comparative studies since 2000-2018 with the limitations of the English language. RESULTS The results provided new evidence about antioxidant, anti-inflammatory, anti- atherogenic, anti- apoptotic, anti- hypertensive, and hypolipidemic effects of saffron. Pharmacological effects of saffron are due to a number of ingredients contained within this spice, including safranal, crocetin and crocins. CONCLUSIONS Our study concludes that saffron with wide range of usefulness in medicine may be the potent candidate in the process of new drug production for the treatment of CVDs.

Abstract
Saffron (Crocus savitus) is a Middle-Eastern herb with strong antioxidant properties. Its major constituents, safranal, crocin, and crocetin, are also antioxidants and bear structural similarities to other well-known natural antixodant substances, such as zeaxanthin. Given the role of oxidative stress in many diseases, considerable interest has been shown into the potential role of saffron supplementation as a treatment for a range of diseases. In vitro and animal studies have provided evidence that saffron and its constituents may be potent therapies for a range of pathologies, including Alzheimer's disease, age-related macular degeneration (AMD) and cardiac ischemia. Whether these findings translate into clinical efficacy, however, has as of yet been incompletely assessed. This makes assessing the role of saffron supplementation in these diseases difficult. Here, we review the current human clinical evidence supporting saffron supplementation as a treatment for a range of pathologies and the underlying science supporting its use.

Abstract
Medicinal plants are important sources of potentially therapeutic biochemical drugs. Crocus sativus L. has been used to treat various diseases in China, the Republic of Korea and Japan. The present study investigated the protective effect of C. sativus L. extract in Drosophila melanogaster intestinal immunity. Wild‑type flies were fed standard cornmeal‑yeast medium and used as controls, and flies supplemented with 1% C. sativus L. aqueous extract in standard medium were used as the experimental group. Following the ingestion of the various toxic compounds, the survival rate of the flies was determined. Cell viability and levels of reactive oxygen species (ROS) were detected using 7‑amino‑actinomycin D and dihydroethidium staining, respectively. The present study demonstrated that aqueous extracts of C. sativus L. may significantly increase the lifespan and survival rate of adult flies. Additionally, C. sativus L. may decrease epithelial cell death and ROS levels, resulting in improved intestinal morphology. These findings indicated that C. sativus L. had a protective effect against intestinal injury and may extend the lifespan of Drosophila. Therefore, the findings of the present study may improve the understanding of clinical researchers on the complex effects of C. sativus L. in intestinal disorders.

Abstract
Saffron is one of the most expensive species of Chinese herbs and has been subjected to various types of adulteration because of its high price and limited production. The present study introduces a loop-mediated isothermal amplification (LAMP) technique for the differentiation of saffron from its adulterants. This novel technique is sensitive, efficient and simple. Six specific LAMP primers were designed on the basis of the nucleotide sequence of the internal transcribed spacer 2 (ITS2) nuclear ribosomal DNA of Crocus sativus. All LAMP amplifications were performed successfully, and visual detection occurred within 60 min at isothermal conditions of 65 °C. The results indicated that the LAMP primers are accurate and highly specific for the discrimination of saffron from its adulterants. In particular, 10 fg of genomic DNA was determined to be the limit for template accuracy of LAMP in saffron. Thus, the proposed novel, simple, and sensitive LAMP assay is well suited for immediate on-site discrimination of herbal materials. Based on the study, a practical standard operating procedure (SOP) for utilizing the LAMP protocol for herbal authentication is provided.

Abstract
Crocus sativus L. (C. sativus), commonly known as saffron, is used as a food additive, preservative, and medicinal herb. Traditionally, it has been used as an alternative treatment for different diseases. C. sativus' medicinal effects are related to its major constituents like crocins, crocetin, and safranal. According to the literature, C. sativus and its constituents could be considered as an effective treatment for neurodegenerative disorders, coronary artery diseases, asthma, bronchitis, colds, fever, diabetes, and so on. Recently, numerous studies have reported such medicinal properties and found that the underlying mechanisms of action may be mediated by antioxidant, inflammatory, and immunomodulatory effects. C. sativus enhances the antioxidant capacity and acts as a free radical scavenger. As an antiinflammatory and immunomodulatory agent, it modulates inflammatory mediators, humoral immunity, and cell-mediated immunity responses. This review highlights in vitro and animal findings regarding antiinflammatory, antioxidant, and immunomodulatory effects of C. sativus and its constituents. Present review found that the C. sativus and its main constituents such as safranal, crocins, and crocetin could be effective against various diseases because of their antioxidant, anti-inflammation, and immunomodulatory effects.

Abstract
BACKGROUND Crocin is the major constituent of saffron, a naturally derived Chinese medicine obtained from the dried stigma of the Crocus sativus flower. It has a variety of pharmacological effects, including anti-oxidative, immunity enhancement, and anti-tumorigenic properties; however, the molecular mechanisms underlying these effects remain unknown. METHODS To investigate the effects of crocin on proliferation and apoptosis of lung adenocarcinoma cells, lung adenocarcinoma cell lines, A549 and SPC-A1, were treated with crocin at different dosages. Cell morphological changes were observed by light microscopy. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed to detect the inhibitory effect of crocin on cell proliferation and sensitivity to chemotherapeutic drugs. Flow cytometry was used to characterize cell apoptosis and cell cycle profiles. Reverse transcription-polymerase chain reaction was used to detect mRNA levels of apoptosis-related genes. RESULTS Crocin inhibited cell proliferation and induced apoptosis in A549 and SPC-A1 cells in a concentration-dependent manner, accompanied with an increase of G0/G1 arrest. Crocin significantly increased the mRNA levels of both p53 and B-cell lymphoma 2-associated X protein (Bax), while decreasing B-cell lymphoma 2 (Bcl-2) mRNA expressions. In addition, crocin combined with either cisplatin or pemetrexed showed additive effects on cell proliferation in two lung cancer cell lines. CONCLUSIONS Crocin significantly suppressed the proliferation of human lung adenocarcinoma cells and enhanced the chemo sensitivity of these cells to both cisplatin and pemetrexed. The actions of molecular mechanism could be through the induction of cell cycle arrest and apoptosis by p53 and Bax up-regulation but Bcl-2 down-regulation.

Abstract
Saffron (Crocus sativus) is a medicinally important plant. The Kashmir valley (J&K, India) emblematizes one of the major and quality saffron producing areas in the world. Nonetheless, the area has been experiencing a declining trend in the production of saffron during the last decade. Poor disease management is one of the major reasons for declining saffron production in the area. Endophytes are known to offer control against many diseases of host plant. During the present study, culturable bacterial endophytes were isolated from saffron plant, identified and assessed for plant growth promoting activities. Molecular and phylogenetic analysis grouped the fifty-four bacterial isolates into eleven different taxa, viz. Bacillus licheniformis, B. subtilis, B. cereus, B. humi, B. pumilus, Paenibacillus elgii, B. safensis, Brevibacillus sp., Pseudomonas putida, Staphylococcus hominis and Enterobacter cloacae. The results were also supported with the identification based on BIOLOG system. B. licheniformis was the dominant endophyte in both leaves and corms of saffron. 81 % isolates showed lipase activity, 57 % cellulase, 48 % protease, 38 % amylase, 33 % chitinase and 29 % showed pectinase activity. 24 % of the isolates were phosphate solublizers, 86 % showed siderophore production and 80 % phytohormone production potential. The present repository of well characterized bacterial endophytes of saffron, have plant growth promoting potential which can be explored further for their respective roles in the biology of the saffron plant.

Abstract
BACKGROUND Throughout the past three decades, increased scientific attention has been given to examining saffron's (Crocus sativus L.) use as a potential therapeutic or preventive agent for a number of health conditions, including cancer, cardiovascular disease, and depression. OBJECTIVE The purpose of this systematic review is to examine and categorize the current state of scientific evidence from randomized controlled trials (RCTs) regarding the efficacy of saffron on psychological/behavioral outcomes. SEARCH STRATEGY Electronic and non-electronic systematic searches were conducted to identify all relevant human clinical research on saffron. The search strategy was extensive and was designed according to the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)." Reference lists of articles that met the inclusion criteria were searched. Only English language studies were reviewed. INCLUSION CRITERIA Saffron trials in combination with other substances and saffron safety studies were considered, in accordance with the PRISMA statement. Included studies must have a control group. Included studies must measure a physiological and/or a behavioral outcome. DATA EXTRACTION AND ANALYSIS The methodological quality of all included studies was independently evaluated by two reviewers using the Jadad score. Mean scores and P-values of measures were compared both inter- and intra-study for each parameter (i.e., depression). RESULTS Twelve studies met our inclusion criteria. These studies examined the effects of saffron on psychological/behavioral outcomes of: major depressive disorder (n=6), premenstrual syndrome (n = 1), sexual dysfunction and infertility (n=4), and weight loss/snacking behaviors (n=1). The data from these studies support the efficacy of saffron as compared to placebo in improving the following conditions: depressive symptoms (compared to anti-depressants and placebo), premenstrual symptoms, and sexual dysfunction. In addition, saffron use was also effective in reducing excessive snacking behavior. CONCLUSION Findings from initial clinical trials suggest that saffron may improve the symptoms and the effects of depression, premenstrual syndrome, sexual dysfunction and infertility, and excessive snacking behaviors. Larger multi-site clinical trials are needed to extend these preliminary findings.

OBJECTIVES Recently, a great deal of interest has been developed to isolate and investigate novel bioactive components from natural resources with health beneficial effects. Saffron is the dried stigma of Crocus sativus L. and has been used for centuries in traditional medicine mainly for its healing properties, as well as for the treatment of various pathological conditions. Objectives of the present review are to unravel its therapeutic properties and investigate the potential applications of saffron in contemporary therapy of a wide spectrum of diseases and summarize previous and current evidence regarding the biological/pharmacological activities of saffron and its active ingredients and their possible therapeutic uses. KEY FINDINGS Recent phytochemistry and pharmacological experiments have indicated that crocin and safranal, the major active ingredients of saffron, exert important actions, such as antioxidant, anti-tumor, anti-diabetic, anti-inflammatory and anti-atherosclerotic. Unfortunately, the vast majority of those data derive from in vitro studies, whereas a limited number of in vivo experiments support the aforementioned effects. In addition to studies with mechanistic implications, very few clinical trials provide preliminary evidence of saffron potentiality to alleviate depression and increase cognitive function in patients with Alzheimer's disease. SUMMARY The history and structural features of saffron constituents are given in the first part of the review, followed by a comprehensive and critical presentation of the published preclinical and clinical studies and review papers on the pharmacology and possible therapeutic uses of saffron and its main active components crocin and safranal.

Abstract
In the present study, we aimed to analyze the antinociceptive, immunomodulatory and antipyretic activities of nymphayol were investigated in wistar rats and mice. Antinociceptive effect was evaluated by acetic acid induced writhing, formalin induced paw licking and hot-plate tests. Immunomodulatory activity was assessed by neutrophil adhesion test, humoral response to sheep red blood cells, delayed-type hypersensitivity, phagocytic activity and cyclophosphamide induced myelosuppression. Antipyretic activity was evaluated by yeast induced hyperthermia in rats. Nymphayol produced signifi cant (p<0.05) antinociceptive activity in acetic acid induced writhing response and late phase of the formalin induced paw licking response. Pre-treatment with nymphayol (50 mg/kg, oral) evoked a signifi cant increase in neutrophil adhesion to nylon fi bres. The augmentation of humoral immune response to sheep red blood cells by nymphayol (50 mg/kg) was evidenced by increase in antibody titres in rats. Oral administration of nymphayol (50 mg/kg) to rats potentiated the delayed-type hypersensitivity reaction induced by sheep red blood cells. Treatment with nymphayol showed a signifi cant (p<0.05) reduction in pyrexia in rats. The results suggest that nymphayol possesses potent anti-nociceptive, immunomodulatory and antipyretic activities.

Serum markers of inflammation and oxidative stress in chronic opium (Taryak) smokers. Immunol Lett 2013; 153:22-6. [PMID: 23850638 DOI: 10.1016/j.imlet.2013.07.001] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2013] [Revised: 07/02/2013] [Accepted: 07/02/2013] [Indexed: 11/24/2022]
Abstract
A relationship between the expression of inflammation markers, oxidative stress and opium use has not been clearly established. This study was done to determine serum high-sensitivity C-reactive protein (hs-CRP), quantity of C3 and C4 complement factors, immunoglobulins, nitric oxide (NO) and total antioxidant capacity (TAC) in opium smokers and non-drug-using control participants. The present study was done on 44 male opium smokers and 44 controls of the same sex and age (20-40 years). The control group was healthy individuals with no lifetime history of drug abuse or dependence. All of the opium abusers were selected from those who had a history of opium use, for at least one year, with a daily opium dosage not less than 2g. Addicts known to abuse alcohol or other drugs were excluded. Serum hs-CRP concentration was measured using ELISA method and serum C3, C4 and immunoglobulins concentration were determined by Single Radial Immunodiffusion (SRID) method. NO production was estimated through Griess reaction and TAC was assessed by Ferric Reducing/Antioxidant Power (FRAP) test. Serum hs-CRP, complement factors (C3 and C4) and FRAP levels were significantly higher in the opium smokers (8.93 ± 1.93; 138.47 ± 13.39; 68.79 ± 7.02 and 972.75 ± 11.55, respectively) relative to the control group (0.72 ± 0.09; 93.36 ± 8.73; 33.08 ± 7.39 and 761.95 ± 18.61, respectively). These results permit us to conclude that opium smokers indeed present with a low to moderate grade inflammation, which is defined by an increase in acute phase proteins.
