The favorable impacts of cardamom on related complications of diabetes: A comprehensive literature systematic review.

BACKGROUND AND AIM: Complementary and alternative medicine plays an increasing role in preventing, and regulatory, complications associated with diabetes. There are plenty of polyphenolic compounds found in Elettaria cardamomum (Cardamom) such as luteolin, limonene, pelargonidin, caffeic acid, kaempferol, gallic acid, and quercetin which can be used in many metabolic diseases. METHOD: The objective of this systematic review was to appraise evidence from clinical and in vivo studies on the effects of cardamom on inflammation, blood glucose, oxidative stress and dyslipidemia of diabetes mellitus. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statements, the present study was carried out. Studies were conducted by searching databases such as EMBASE, Scopus, PubMed, Google Scholar, web of sciences, and Cochrane Library from the commencement until April 2022. RESULTS: All available human and animal studies examining the effects of cardamom on diabetes were published in the form of English articles. Finally, only 14 of the 241 articles met the criteria for analysis. Of the 14 articles, 8 were in vivo studies, and 6 were clinical trial studies. Most studies have indicated the beneficial effects of cardamom on insulin resistance, oxidative stress and inflammation. Cardamom also improved dyslipidemia, but had no substantial effect on weight loss. CONCLUSION: According to most studies, cardamom supplementation enhanced antioxidant enzyme production and activity in diabetes mellitus and decreased oxidative stress and inflammatory factors. Despite this, the exact mechanism of the disease needs to be identified through more clinical trials.

Thymus vulgaris ameliorates cough in children with asthma exacerbation: a randomized, triple-blind, placebo-controlled clinical trial

Background: Asthma is one of the most common chronic respiratory diseases with inflammatory involvement and has a high burden worldwide. This study aimed to determine the effect of Thymus vulgaris (TV) on cough in children between 5 and 12 years old with mild to moderate asthma exacerbation. Methods: In this randomized, triple-blind clinical trial, 60 children between the ages of 5 and 12 with asthma exacerbations were randomly divided into two groups. The intervention group (n = 30) was given TV powder at a dose of 20 mg/kg every 8 hours, prepared as syrup, along with routine medical treatment for a week, and the control group (n = 30) received only routine medical treatment with placebo syrup. At the end of the week, clinical and laboratory symptoms, and spirometry data were re-recorded for both groups. Finally, the recorded factors were compared and statistically analyzed. Results: The results showed that after the intervention, activity-induced cough reduced, and difference was statistically significant between the two groups (p = 0.042), but the reduction in wheezing and breathlessness had no statistically significant difference. Spirometry data showed a significant difference in forced expiratory volume in 1 second (FEV1) between the two groups after intervention (p = 0.048), but this difference was not significant in FEV1/FVC (forced vital capacity), peak expiratory flow (PEF), and forced expiratory flow at 25–75% of the vital capacity (FEF25–75%). Conclusion: The results show that TV syrup may be useful as an adjuvant treatment in children with asthma exacerbations (AU)

Effects of curcumin on blood pressure: A systematic review and dose-response meta-analysis.

AIMS: This systematic review and dose-response meta-analysis were conducted to summarize data from available clinical trials on the effects of curcumin supplementation on systolic BP (SBP) and diastolic BP (DBP). DATA SYNTHESIS: Using related keywords, multiple databases, including the Web of Sciences, Scopus, Embase, PubMed, Cochrane Library, and Google Scholar, were searched until November 2022. We chose the studies that examined the effects of curcumin on systolic blood pressure (SBP) and diastolic blood pressure (DBP). Seventeen eligible studies with a total sample size of 1377 participants were included in the meta-analysis. The findings of the meta-analysis did not indicate any significant effect of curcumin on SBP (WMD = -0.06 mmHg, 95% CI: -0.62, 0.50, p = 0.85; I2 = 44.2%) and DBP (WMD = -0.18 mmHg, 95% CI: -1.17, 0.82, p = 0.62; I2 = 77.2%). Moreover, in our dose-response analysis, we found that the dose and duration of curcumin supplementation were non-significantly associated with the reduction of SBP and DBP. However, subgroup analysis revealed a significant reduction only in DBP levels (WMD: -0.76 mmHg, 95% CI: -1.46,-0.05; P = 0.03) but not in SBP in studies with ≥12-week supplementation. Also, a significant reduction in SBP (WMD: -1.55 mmHg, 95% CI: -2.85, -0.25; P = 0.01) and DBP (WMD: -1.73 mmHg, 95% CI: 2.67, -0.79; P < 0.01) was noticed by curcumin supplementation in studies performed on women. CONCLUSIONS: The current study suggests that consuming curcumin may improve DBP when administered for long durations ≥12 weeks. However, more trials are required to confirm these findings.

Effect of hydrotherapy, balneotherapy, and spa therapy on blood pressure: a mini-review.

Hypertension (high blood pressure) is one of the most common health conditions. When your blood pressure is high for a long term, it can cause health problems, such as heart disease. In addition to the main methods of treatment, there are various methods of adjuvant therapy, one of the most common of which is hydrotherapy. In this review study, we examined the effects of hydrotherapy, balneotherapy, and spa therapy on blood pressure. We searched the PubMed/MEDLINE, Web of Science, Scopus, and Science Direct databases until April 2022 using related keywords. In summary, the current study shows that different hydrotherapy methods may improve blood pressure. Hydrotherapy as one of the adjunctive therapy methods can be effective in lowering blood pressure. Blood circulation is smoothed by the warmth of the water. This improvement may be achieved by regulating heart rate, releasing hormones that control blood pressure, or regulating the activity of baroreceptors or chemoreceptors. In addition to using medications, hypertension patients also use non-pharmacological approaches in their care, including hydrotherapy, balneotherapy, and warm water foot soaks performed at home. Although several lines of evidence show the potential effects of hydrotherapy, balneotherapy, and spa therapy on blood pressure, many clinical trials are needed.

Efficacy of hydrotherapy, spa therapy, and balneotherapy on sleep quality: a systematic review.

The purpose of this article was to review and assess the results obtained from human studies on the effects of hydrotherapy, balneotherapy, and spa therapy on sleep disorders. In this study, databases such as Pubmed, Embase, Web of Science, Google Scholar, Cochrane, Scopus, and sciences direct database were searched from the beginning to September 2022. All human studies that examined the effect of hydrotherapy, balneotherapy, and spa therapy on sleep disorders were published in the form of a full article in English. In the end, only 18 of the 189 articles met the criteria for analysis. Most studies have shown that balneotherapy, spa therapy, and hydrotherapy may by affecting some hormones such as histamine, serotonin, sympathetic nerves, and regulating body temperature led to increased quality and quantity of sleep. Also, the results obtained from Downs and Black show that 3 studies were rated as very good, 7 studies as good, 7 studies as fair, and 1 study as weak. The results of studies also showed that hydrotherapy leads to an improvement in the PSQI score index. Nevertheless, more clinical trials are needed to determine the mechanism of action of hydrotherapy on sleep disorders.

The role of ginseng derivatives against chemotherapy-induced cardiotoxicity: A systematic review of non-clinical studies.

Aims: Although chemotherapy agents are used to treating cancers, they have serious side effects, like their harmful effects on the cardiovascular system, limiting the clinical use of these chemotherapy agents. This study aimed to systematically investigate the potential role of ginseng derivatives in the prevention of chemotherapy-induced cardiac toxicity. Methods: This systematic review was performed according to PRISMA guidelines strategy in databases till August 2022. First, identify studies related to using search terms in titles and abstracts. After studying and screening 209 articles, 16 articles were selected in this study according to our inclusion and exclusion criteria. Results: According to the findings of this study, ginseng derivatives showed significant changes in biochemical, histological, and heart weight loss, as well as a reduction in mortality, which occurred in the groups treated with chemotherapy agents compared to the control groups. Co-administration of ginseng derivatives with chemotherapy agents inhibited or reversed these changes to near-moderate levels. The protective effects of ginseng derivatives can be due to their anti-inflammatory, anti-oxidant, and anti-apoptotic action. Conclusion: This systematic review shows evidence that concomitant administration of ginseng derivatives improves chemotherapy-induced cardiac toxicity. However, for better conclusions about the practical mechanisms of ginseng derivatives in reducing the cardiac toxic effects of chemotherapy agents and evaluating the efficacy and safety of the compound simultaneously, it is necessary to design comprehensive studies.

METHODS: The present systematic review was conducted according to the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statements. Also, for this study databases such as Embase, PubMed, Scopus ProQuest, and sciences direct database were searched from the beginning to April 2021. RESULTS: All human studies that examined the effect of balneotherapy, spa therapy, and hydrotherapy on psoriasis and atopic dermatitis were published in the form of a full article in English. In the end, only 22 of the 424 articles met the criteria for analysis. Most studies have shown that balneotherapy, spa therapy, and hydrotherapy may reduce the effects of the disease by reducing inflammation and improving living conditions. In addition, the results of the Downs and Black score show that seven studies received very good scores, three studies received good scores, nine studies received fair scores, and three studies received poor scores. CONCLUSIONS: The results of studies also showed that hydrotherapy leads to an improvement in the PASI score index. Nevertheless, more clinical trials are needed to determine the mechanism of action of hydrotherapy on these diseases.

Potential roles of genistein in polycystic ovary syndrome: A comprehensive systematic review.

Polycystic ovary syndrome (PCOS) is one of the most prevalent polygenic endocrine disorders in reproductive-age women. Genistein is a soy-isolated phytoestrogen and isoflavone with antioxidant, anti-inflammatory, estrogenic, and antineoplastic activity. This systematic review aimed to investigate the therapeutic effects and mechanisms of actions of genistein in PCOS. The present study was conducted according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. We searched PubMed, Scopus, Embase, and Google Scholar databases up to February 2022 using relative keywords. Studies published in English evaluated genistein's effects on PCOS, and its related symptoms were considered. Out of 298 records screened, only 13 articles met the inclusion criteria: Nine animal and 4 human studies. The results of the current study indicated that genistein supplementation may effectively improve PCOS-related symptoms by decreasing insulin resistance and anthropometric indices, improving ovarian morphology and regulating reproductive hormones, and reducing oxidative stress and inflammation by influencing biological pathways. According to the current literature, genistein may diminish the dues of PCOS. Therefore, this study shows that genistein can be considered an effective agent. in reducing the complications of PCOS. However, further studies are recommended for a broad conclusion on the exact mechanism of genistein in PCOS patients.

Complementary and integrative remedies in the treatment of chronic pruritus: A review of clinical trials.

BACKGROUND: Chronic pruritus is one of the most common conditions in dermatology and a common manifestation in many systemic diseases. Since the etiology of chronic pruritus remains somewhat unknown, hence, conventional medications may not always show a good therapeutic response. This finding has led both investigators and patients to use herbal and complementary remedies for its treatment. The aim of this study was to review clinical trials in which herbal and complementary medicine was used in the control and treatment of chronic pruritus. MATERIALS AND METHODS: In this study, we reviewed related articles in this domain, from 2000 to 2020. The search involved electronic databases including PubMed, Scopus, Web of Science, Cochrane, Google Scholar, and SID databases using the keywords "pruritus," "itch," "herb," "complementary medicine," "traditional medicine," "integrative medicine," and their related MeSH terms. Finally, we extracted the pertinent information from these articles and summarized the results. RESULTS: The findings of this study showed that 17 clinical trials have been conducted till date in order to evaluate the efficacy of herbal remedies and complementary medicines in the treatment of chronic pruritus. Herbal remedies including turmeric, Fumaria parviflora, Avena sativa, capsaicin, sweet almond oil, peppermint oil, violet oil, vinegar, as well as manual therapies including aromatherapy, auricular acupressure, and acupuncture, were significantly effective in the treatment of chronic pruritus. CONCLUSION: There are only a few studies published on the therapeutic efficacy of herbal remedies and complementary medicine in the treatment of chronic pruritus. Some have shown promising results. Therefore, more evidence-based studies are needed in order to determine if herbal remedies and complementary medicine could be an effective alternative or adjuvant treatment modality in chronic pruritus.

The potential role of saffron (Crocus Sativus L.) and its components in oxidative stress in diabetes mellitus: A systematic review.

BACKGROUND AND AIMS: Diabetes mellitus is one of the most important life-threatening metabolic diseases of the 21st century. The use of complementary and alternative medicine in diabetic patients seems to be increasing. Saffron, a valuable herbal medicine, has several pharmacological properties such as anti-oxidant effect, which can play important role in ameliorating the complications of diabetes. The aim of this study was to systematically review the therapeutic effects of saffron and its bioactive components on oxidative stress in diabetes mellitus. METHODS: In this systematic review, databases such as PubMed, SCOPUS, Embase, ProQuest, and Web of Sciences were searched from the beginning to December 2021. All eligible in vitro, animal, and human studies that examined the effect of saffron on oxidative stress indices in diabetes were prepared in the form of a full article in English. RESULTS: In the end, only 31of the 389 articles met the criteria for analysis. Of the 31 articles, 4 were in-vitro studies, 25 were animal studies, and 2 were clinical trials studies. Saffron supplementation may activate insulin receptor substrate 1 (IRS1) and peroxisome proliferator-activated receptor gamma (PPAR-γ), which can improve hyperglycemia and insulin transduction signal in adipose tissue, and regulate glucose metabolism, leading to an increased nuclear factor erythroid 2-related factor 2 (Nrf2), HO-1 expression, amelioration of mitochondrial function, and an increased levels of antioxidant enzymes. CONCLUSION: Most studies have shown that saffron supplementation significantly enhanced the production and activity of antioxidant enzymes and decreased oxidative stress indices in diabetes mellitus. However, human pharmacokinetic and more accurate clinical trial studies are needed to determine dose ranges and the exact mechanisms of action of saffron and its active components in diabetes.

The mechanisms of saffron (Crocus sativus') on the inflammatory pathways of diabetes mellitus: A systematic review.

BACKGROUND: and amis: Diabetes is one of the major medical problems, which can lead to damage to cells or organs in various parts of the body. Saffron as herbal medicine has contained several active ingredients, including safranal, flavonoids, crocetin, and crocin, which are effective in modulating oxidative stress and inflammation, which can play the main role in reducing the effects of diabetes. However, so far, the effect of saffron on diabetes inflammation has not been evaluated in the form of systematic review studies. The purpose of this systematic study was to evaluate the evidence obtained from in-vitro, animal, and clinical trials studies on the effects of saffron on inflammation in diabetes. METHODS: The present systematic review was conducted according to the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statements. In this systematic review, databases such as Embase, Pubmed, SCOPUS, ProQuest, and sciences direct database were searched from the beginning to February 2021. All eligible in-vitro, animal and human studies that examined the effect of saffron on inflammatory factors in diabetes were published in the form of a full article in English. RESULTS: In the end, only 20 of the 596 articles met the criteria for analysis. Of the 20 articles, 3 were in-vitro studies, 13 were animal studies, and 4 were human studies. CONCLUSION: The findings of this systematic study (Except for two studies) suggest that saffron supplementation with potential anti-inflammatory properties may reduce the expression of the inflammatory pathway and the production of inflammatory products in diabetes.

BACKGROUND: Cichorium intybus is a rich source of terpenoids and phenolic compounds, one of the effective methods in managing and reducing the complications of chronic diseases such as diabetes mellitus. The purpose of this systematic review was to evaluate the evidence obtained from animal and human studies on the effects of chicory on metabolic indicators (such as inflammation, oxidative stress, blood sugar and dyslipidaemia) of diabetes mellitus. MATERIALS AND METHODS: This systematic search was performed in ProQuest, PubMed, Google Scholar, Scopus, Cochrane Central Register of Controlled Trials, Embase and Science Direct databases and on articles published until August 2021. All of the animal studies and clinical trials included in this systematic review that assessed the effect of chicory on metabolic risk markers in diabetes were published in English language journals. RESULTS: Finally, amongst 686 articles, only 23 articles met the needed criteria for further analysis. Out of 23 articles, 3 studies on humans and 20 studies on animals have been carried out. Fifteen of the 19 studies that evaluated the effect of chicory on the glycaemic index showed that Cichorium intybus improved blood glucose index (it had no effect in two human studies and three animal studies). Ten of the 13 studies evaluating the effect of Cichorium intybus on lipid profiles showed that it improved dyslipidaemia. Also, all 12 studies showed that chicory significantly reduces oxidative stress and inflammation. CONCLUSION: According to the available evidence, Cichorium intybus might improve the glycaemic status, dyslipidaemia, oxidative stress and inflammation. However, further studies are recommended for a comprehensive conclusion about the exact mechanism of chicory in diabetic patients.

A comprehensive review of clinical studies with herbal medicine on polycystic ovary syndrome (PCOS).

BACKGROUND: Polycystic ovary syndrome (PCOS) is a frequent medical condition characterized by both metabolic and reproductive disorders. Different pharmaceutical treatments have been proposed for PCOS. However, side effects of long-term treatments and their probable low efficacy have made complementary and alternative treatments a valuable option. Recent reports have indicated the increased use of complementary treatments. Herbal medicine, as part of complementary medicine, was find introduced in traditional Persian and Chinese medicine. Medicinal herbs have used for a long time in the treatment of gynecological and infertility problems of PCOS patients. In this study, we aimed to review herbal medicines used for PCOS worldwide. METHODS: PubMed, Embase, Cochrane, and Scopus databases were searched for clinical trials and Randomized Controlled Trials based on related keywords. Data were collected from 1990 to 2019. RESULTS: According to a multitude of studies, a wide spectrum of herbs can be used to improve various aspects of PCOS. Herbs such as Cinnamomum verum, Trigonella foenum-graecum L., and Vitex agnus-castus can impact on menstrual and ovulatory dysfunctions, obesity, insulin resistance, lipid-metabolism dysfunction, and androgen excess-related conditions. CONCLUSION: Some plants as natural remedies may have beneficial effects on improving different aspects of PCOS; but further studies are needed to investigate their mechanisms and safety.

Herbal Medicine for Oligomenorrhea and Amenorrhea: A Systematic Review of Ancient and Conventional Medicine.

INTRODUCTION: Menstrual bleeding cessation is one of the most frequent gynecologic disorders among women in reproductive age. The treatment is based on hormone therapy. Due to the increasing request for alternative medicine remedies in the field of women's diseases, in present study, it was tried to overview medicinal plants used to treat oligomenorrhea and amenorrhea according to the pharmaceutical textbooks of traditional Persian medicine (TPM) and review the evidence in the conventional medicine. METHODS: This systematic review was designed and performed in 2017 in order to gather information regarding herbal medications of oligomenorrhea and amenorrhea in TPM and conventional medicine. This study had several steps as searching Iranian traditional medicine literature and extracting the emmenagogue plants, classifying the plants, searching the electronic databases, and finding evidences. To search traditional Persian medicine references, Noor digital library was used, which includes several ancient traditional medical references. The classification of plants was done based on the repetition and potency of the plants in the ancient literatures. The required data was gathered using databases such as PubMed, Scopus, Google Scholar, Cochrane Library, Science Direct, and web of knowledge. RESULTS: In present study of all 198 emmenagogue medicinal plants found in TPM, 87 cases were specified to be more effective in treating oligomenorrhea and amenorrhea. In second part of present study, where a search of conventional medicine was performed, 12 studies were found, which had 8 plants investigated: Vitex agnus-castus, Trigonella foenum-graecum, Foeniculum vulgare, Cinnamomum verum, Paeonia lactiflora, Sesamum indicum, Mentha longifolia, and Urtica dioica. Conclusion. Traditional Persian medicine has proposed many different medicinal plants for treatment of oligomenorrhea and amenorrhea. Although just few plants have been proven to be effective for treatment of menstrual irregularities, the results and the classification in present study can be used as an outline for future studies and treatment.

Effects of Withania somnifera on Reproductive System: A Systematic Review of the Available Evidence.

INTRODUCTION: Withania somnifera (WS) also known as ashwagandha is a well-known medicinal plant used in traditional medicine in many countries for infertility treatment. The present study was aimed at systemically reviewing therapeutic effects of WS on the reproductive system. METHODS: This systematic review study was designed in 2016. Required data were obtained from PubMed, Scopus, Google Scholar, Cochrane Library, Science Direct, Web of Knowledge, Web of Science, and manual search of articles, grey literature, reference checking, and expert contact. RESULTS: WS was found to improve reproductive system function by many ways. WS extract decreased infertility among male subjects, due to the enhancement in semen quality which is proposed due to the enhanced enzymatic activity in seminal plasma and decreasing oxidative stress. Also, WS extract improved luteinizing hormone and follicular stimulating hormone balance leading to folliculogenesis and increased gonadal weight, although some animal studies had concluded that WS had reversible spermicidal and infertilizing effects in male subjects. CONCLUSION: WS was found to enhance spermatogenesis and sperm related indices in male and sexual behaviors in female. But, according to some available evidences for spermicidal features, further studies should focus on the extract preparation method and also dosage used in their study protocols.
