A Systematic Review and Meta-Analysis of Ayurvedic Herbal Preparations for Hypercholesterolemia

Immunomodulatory effect of allium sativum in type 2 diabetes mellitus

Type 2 diabetes mellitus (T2DM) is a metabolic disorder marked by chronic hyperglycemia and low-grade inflammation, contributing to various complications. Natural agents with immunomodulatory and antioxidant properties have gained attention as adjunct therapies. To review the effects of Allium sativum on inflammatory pathways and metabolic alterations associated with T2DM. A narrative review was performed using PubMed/MEDLINE, EMBASE, and Scielo databases. The search included terms such as “allium sativum”, “inflammation", “oxidative stress”, and “diabetes mellitus”. Studies in English and Spanish - ranging from clinical trials to meta-analyses - were selected based on relevance. Bioactive compounds such as allicin, S-allyl cysteine, and diallyl disulfide exhibit anti-inflammatory, antioxidant, hypoglycemic, and lipid-lowering actions. Preclinical studies show improved glucose metabolism, insulin sensitivity, and organ function. Moreover, clinical evidence supports reductions in fasting glucose, hemoglobin A1c, blood pressure, and oxidative stress, with good safety profiles. Allium sativum appears to be a promising adjuvant in T2DM management, offering metabolic and anti-inflammatory benefits. Nonetheless, further high-quality clinical trials are needed to confirm its long-term efficacy and standardize its therapeutic use.

The effect of plant growth regulators, FeO3-CTs nanoparticles and LEDs light on the growth and biochemical compounds of black seed (Nigella sativa L.) callus in vitro

BACKGROUND

black seed (Nigella sativa L.) has long been utilized in traditional medicine and as a food ingredient due to its potential therapeutic properties including its effectiveness against cancer, coronaviruses, and bacterial infections. Recently, it has garnered significant attention for its rich reservoir of beneficial secondary metabolites. In vitro culture of black seeds presents an efficient and modern approach for the large-scale production of these valuable compounds, offering advantages such as space efficiency, reduced time, and lower costs. This study aimed to develop and optimize a protocol for callus induction and the identification of key secondary metabolites, including thymoquinone (TQ), phenolic compounds, and flavonoids. To induce callus formation in seed explants, two plant growth regulators (PGRs) were applied individually or in combination and incorporated into Murashige and Skoog (MS) culture medium.

RESULTS

The combination of Auxin, 2,4-dichlorophenoxyacetic acid (2,4-D) and cytokinin, 6-benzylaminopurine (BAP), effectively induced callus formation in most explants, with the response varying based on concentration. The highest callus fresh weight (7.02 g) was obtained on Red(R) LED lighting with FeO3-CTs nanoparticles (100 mg/L- 1), which also resulted in the highest dry weight (1.307 g) after 40 days of cultivation. Similarly, the highest levels of phenols, flavonoids and amino acids were observed under R LED with FeO3-CTs nanoparticles (100 mg L- 1), while FeO3-CTs nanoparticles at 100 and 200 mg/L- 1) exhibited significant effects on metabolite production. In contrast, the antioxidant activity against DPPH free radicals and total carbohydrate accumulation were enhanced in callus cultures treated with FeO3-CTs nanoparticles (200 mg/L- 1) under dark conditions. Additionally, GC-MS analysis revealed that FeO3-CTs nanoparticles (100 mg/L- 1) yielded the most effective enhancement of secondary metabolites under blue (B) LED light at a concentration of 295 mg/L- 1.

CONCLUSION

The finding of this study highlights the potential of the proposed method for the large-scale production of secondary metabolites, total carbohydrates, amino acids, phenolic compounds, and flavonoids from black seed callus cultures in a controlled environment. This optimized approach offers a cost-effective and space-efficient strategy for enhancing bioactive compound synthesis, with potential applications in pharmaceutical and nutraceutical industries.

Commiphora mukul (Hook. ex Stocks) Engl.: Historical records, application rules, phytochemistry, pharmacology, clinical research, and adverse reaction

ETHNOPHARMACOLOGICAL RELEVANCE

Commiphora mukul (Hook. ex Stocks) Engl. (also known as Guggulu) is one of the oldest and most prominent herb used in Ayurvedic medicine. Commiphora mukul plants have traditionally been used to treat inflammation, diabetes, rheumatism, arthritis, obesity, and hyperlipidemia. It has long been used in China, India, Greece, and other countries. Commiphora mukul is an over-the-counter dietary supplement in the United States and Western countries. Commiphora mukul has excellent medicinal and commercial value and deserves further investigation.

AIM OF THE STUDY

This paper systematically reviews the historical records, application rules, phytochemistry, pharmacokinetics, pharmacology, clinical research, and adverse reactions of C. mukul and provides a reference for its comprehensive application in basic research, new drug development, and clinical treatment.

MATERIALS AND METHODS

Literature were collected from databases such as PubMed, CNKI, Web of Science, TBRC, and other sources such as ancient books on traditional medicine, classic books on herbal medicine, and modern monographs. In this study, the application history and modern pharmacological research on C. mukul in the medicine of all ethnic groups were comprehensively and systematically reviewed.

RESULTS

According to the vast literature, the varieties, morphological characteristics, distribution, and description of C. mukul used in Unani medicine, Ayurveda, traditional Chinese medicine, Tibetan medicine, Mongolian medicine, and Uygur medicine are highly consistent. Commiphora mukul is mainly used to treat rheumatoid arthritis, heart disease, obesity, hemorrhoids, urinary system diseases, skin diseases, inflammation, diabetes, hyperlipidemia, tumors, and other diseases. The core medicinal material combination in different ethnic medical preparations was C. mukul-Terminalia chebula Retz. (101 times), C. mukul-Moschus (55 times), C. mukul-Aucklandia lappa (Decne.) Decne. (52 times), and C. mukul-Acorus calamus L (27 times). Phytochemical studies confirmed that 150 components with different structures had been isolated and identified. Z-and E-guggulsterone are the main isomers in C. mukul. C. mukul has anti-cancer, anti-inflammatory, antioxidant, hypolipidemic, bone resorption, nervous system protection, myocardial protection, antibacterial, and other pharmacological properties. Clinical studies have only identified the role of C. mukul in treating hemorrhoids and lowering blood lipids.

CONCLUSIONS

As an essential traditional medicine, C. mukul is widely used in the national traditional medicine system, and rich in chemical constituents and exhibit pharmacological activities. This study found that current research on C. mukul mainly focuses on its chemical composition and pharmacological properties. However, scientific research on the quality control of medicinal materials, identification of original plants, pharmacokinetics, and toxicology are relatively weak, and research in this area needs to be strengthened.

A Scoping Review of Ayurveda Studies in Women with Polycystic Ovary Syndrome

Introduction: Polycystic Ovary Syndrome (PCOS) is a complex disorder with diverse clinical presentations. Women with PCOS use traditional, complementary, and integrative medicines, including Ayurveda (traditional Indian medicine) to manage their symptoms. Therefore, it is important to understand the current evidence base and the potential areas that require further research. Objective: This novel study aimed at providing a description of the Ayurveda studies conducted on women with PCOS and identifying gaps for future research. Methods: This scoping review was undertaken using the Joanna Briggs Institute scoping review guidelines. Relevant electronic databases were searched for any peer-reviewed original research that examined the role of Ayurveda (interventions using single/compound formula of herbs or minerals or metals, Panchakarma procedures and other therapies, and Ayurveda-based diet and lifestyle) for managing symptoms of PCOS in women of reproductive age. Two reviewers independently screened the records, extracted the data on population, intervention, comparator, and outcome characteristics and descriptively summarized the data. Results: Of the 1820 records identified, 57 articles met the inclusion criteria; 32 case studies, 13 randomized controlled trials, 9 pre-post trials, 2 case series, and 1 non-randomized trial. Most studies were conducted in India and used either a compound formula or a complex intervention (e.g., panchakarma therapies and lifestyle modifications). The majority of the case studies/series used an Ayurvedic diagnostic approach that influenced the choice of Ayurveda intervention. Among the interventions, shatapushpa (dill seeds) and krishnatila (black sesame seeds) were the most used single herbs whereas kanchanara guggulu and rajapravartini vati were the most used compound formulas. Basti karma (therapeutic enema) was the most used complex intervention. Reproductive outcomes were the most studied; menstruation, PCOS-related infertility, and polycystic ovary morphology. Conclusions: There are a number of clinical studies on Ayurveda interventions for PCOS with a promising role in managing symptoms of PCOS. However, a few gaps were identified. Future research should aim at: (1) exploring a wider range of interventions, including Ayurvedic diet and lifestyle in different settings/locations; (2) exploring the effectiveness of Ayurveda treatments as an adjunct to biomedical treatments (3) a greater range of outcome measures such as obesity, type 2 diabetes, anxiety, depression, and quality of life needs to be further explored in women with PCOS; and (4) finally, safety and adverse event reporting needs to be undertaken rigorously and systematically.

Ayurveda for managing noncommunicable diseases in organisation for economic co-operation and development: A qualitative systematic review protocol on experiences, perceptions, and perspectives of ayurvedic practitioners and patients

Background and Aims

Ayurveda is a traditional medicine that originated in the Indian subcontinent, and its use remains widespread in the Indian subcontinent, especially for managing noncommunicable diseases (NCDs). It is also becoming increasingly popular in the Organization for Economic Co-operation and Development (OECD) countries as complementary and alternative medicine. Qualitative research studies have been conducted in various OECD countries to explore the experiences, perceptions, and perspectives of Ayurvedic practitioners and patients with NCDs regarding the usage of Ayurveda for managing these conditions. However, to date, no systematic review on this topic has been published. Therefore, this systematic review aims to synthesize the experiences, perceptions, and perspectives of Ayurvedic practitioners and patients with NCDs on the usage of Ayurveda for managing these conditions in OECD countries.

Methods

The systematic review will be conducted in accordance with the joanna briggs institute systematic review guideline on qualitative evidence. We will include qualitative research studies conducted among Ayurvedic practitioners or adult patients with NCDs in any OECD member country to explore experiences, perceptions, or perspectives regarding the usage of Ayurveda for managing NCDs. MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), PsycINFO (Ovid), AMED, and Web of Science will be searched to identify published studies. EthOS and ProQuest Dissertations and Theses will be searched to identify unpublished studies. No date or language restrictions will be applied. Initially, a narrative synthesis will be conducted. Where possible, study findings will be pooled using the meta-aggregation approach.

In recent years, there has been growing scientific interest in the search for natural radioprotectors that can be used to mitigate the effects of radiation on patients, healthcare personnel, and even for space travel. This narrative review covers the past fifty years and focuses on herbal preparations of Ayurvedic, Traditional Chinese, and Kampō Medicines that have the potential to reduce or eliminate the harmful effects of radiation. Our findings highlight ten herbal preparations, namely Abana, Amalakyadi Churna, Amritaprasham, Brahma, Bu-zhong-yi-qi-tang (BZYQT), Chyavanaprasha, Cystone, Geriforte, Mentat, and Triphala, which have demonstrated potential radioprotective effects. This review examines their composition, properties, and possible mechanisms of action in relation to their radioprotective properties. Exploring the ethnobotany of traditional Asian medicine is particularly interesting as it may lead to the discovery of new active compounds with radioprotective properties.

Nigella sativa and health outcomes: An overview of systematic reviews and meta-analyses

Background

Nigella sativa (N. sativa) consumption has been associated with various health outcomes; however, the results are not completely consistent.

Objectives

This overview of systematic reviews and meta-analyses aimed to evaluate the reporting and methodological quality, and to grade the available evidence of associations between N. sativa and health outcomes.

Methods

PubMed, Cochrane Library, Embase, and Scopus databases were searched from their inception to September 30, 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 statement, Assessment of Multiple Systematic Reviews (AMSTAR) 2 checklist, and Grades of Recommendations, Assessment, Development and Evaluations (GRADE) systems were used to assess the reporting, methodological, and evidence quality for each meta-analysis, respectively. The results were synthesized in a narrative form.

Results

This overview included 20 eligible meta-analyses published in peer-reviewed journals between 2013 and 2021. The overall methodological quality was relatively poor, with only one moderate quality, four low quality, and 15 critically low quality studies. For reporting quality, items two, five, eight, nine, 15, and 24 need to improve. Among the 110 outcome indicators of the quality of evidence, five were graded as moderate, 17 as low, and 88 as very low. Risk of bias, inconsistency, and imprecision were the main downgrading factors.

Conclusion

This overview suggests that N. sativa is beneficial for various clinical outcomes. However, there are certain limitations to reporting and methodological quality. The clinical efficacy of N. sativa requires confirmation in high-quality, large-sample, randomized controlled trials.

The Use of Medicinal Plants in Blood Vessel Diseases: The Influence of Gender

Data available in the literature on the use of herbal products to treat inflammation-related vascular diseases were considered in this study, while also assessing the influence of gender. To this end, the articles published in PubMed over the past 10 years that described the use of plant extracts in randomized clinical trials studying the effectiveness in vascular pathologies were analyzed. The difference in efficacy of plant-derived preparations in female and male subjects was always considered when reporting. The safety profiles of the selected plants were described, reporting unwanted effects in humans and also by searching the WHO database (VigiBase^®). The medicinal plants considered were Allium sativum, Campomanesia xanthocarpa, Sechium edule, Terminalia chebula. Additionally, an innovative type of preparation consisting of plant-derived nanovesicles was also reported.

Biological properties and therapeutic applications of garlic and its components

Garlic is one of the most widely employed condiments in cooking. It has also been used since ancient times in traditional plant-based medicine, largely based on its organosulfur compounds. The objective of this study was to provide updated information on the biological and therapeutic garlic properties. Garlic has been found to possess important biological properties with high therapeutic potential, which is influenced by the mode of its utilization, preparation, and extraction. It has been attributed with antioxidant, anti-inflammatory, and immunomodulatory capacities. Garlic, in particular its organosulfur compounds, can maintain immune system homeostasis through positive effects on immune cells, especially by regulating cytokine proliferation and expression. This may underlie their usefulness in the treatment of infectious and tumor processes. These compounds can also offer vascular benefits by regulating lipid metabolism or by exerting antihypertensive and antiaggregant effects. However, further clinical trials are warranted to confirm the therapeutic potential of garlic and its derivatives.

The Administration of Probiotics against Hypercholesterolemia: A Systematic Review

Hypercholesterolemia is a key factor in the progression of atherosclerosis and cardiovascular disease (CVD). CVD is a significant public health concern with a high death rate. Some of the main factors linked to CVD include genetics and lifestyle. Dyslipidemia has been one of the factors related to the onset of several CVD-related diseases. Several clinicopathological studies have shown a correlation between high cholesterol levels, particularly low-density lipoprotein cholesterol (LDL-c), and CVD development. Probiotics have received a lot of attention for various beneficial effects, especially their ability to reduce blood cholesterol in humans. Probiotics were shown in several investigations to affect hypercholesterolemia by influencing cholesterol biosynthesis. The current review focuses on the human dietary interventions with probiotics and their effects on CVD risk factors and hypercholesterolemia. The outcomes are debatable and consider various parameters such as probiotic strain, dosing frequency, therapeutic response, dietary changes, and so forth. As a result, probiotics have the propensity to become dietary supplements in moderate/severe hypercholesterolemic patients, which significantly reduces the CVD risk.
