Insights & Discussion
Pomegranate has been confirmed to improve clinical features and reduce inflammatory, oxidative stress, and apoptosis markers in osteoarthritis.
In the methodology, a systematic review was conducted using established databases like Scopus, PubMed, Embase, WOS, ProQuest, and Google Scholar up until February 2021. Both MESH and non-MESH keyword searches were performed in the title, abstract, and keywords. The review considered full-text clinical, animal, and in vitro studies in all languages and specifically excluded review articles, book chapters, conference abstracts, and research related to pomegranate in health problems other than osteoarthritis. A manual search was performed to examine the references or citations of eligible papers as well as grey literature to discover potential researches.
The results of the systematic review included twenty-three articles which all showed the beneficial impact of pomegranate across human, animal, and in vitro studies. These showed improvements in clinical presentations and reductions in inflammatory, oxidative stress, and apoptosis markers in osteoarthritis. This demonstrated the therapeutic potential of pomegranate for easing the effects of osteoarthritis.

Pomegranate juice consumption appears to somewhat enhance inflammatory status and complete blood count in hospitalized COVID-19 patients.

Randomised Controlled Trial Common Cold, Flu & Viral Infections COVID-19 CRP
The study was a randomized, double-blinded placebo-controlled trial involving 48 patients and had two parallel arms. As part of their standard hospital care, patients were either given 500 mL of whole pomegranate juice daily or a placebo for a period of 14 days. The researchers focused on measuring inflammatory indicators and complete blood counts both at the start of the study and at the end of the 14-day intervention period.
Following the 14-day intervention, there was a distinguishable decrease in primary outcomes including inflammatory markers such as C reactive protein, interleukin-6, and erythrocyte sedimentation rate in the group that consumed pomegranate juice as compared to the readings before the intervention. In addition, considerable changes were also observed in secondary outcomes such as neutrophils, lymphocytes, platelets, platelets-to-lymphocyte and neutrophils-to-lymphocyte ratios in the pomegranate juice group compared to the parameters before the intervention. Finally, the mean changes in levels of interleukin-6, white blood cells, neutrophils, lymphocyte, platelets, platelets-to-lymphocyte ratio, blood oxygen saturation and MCV were significantly different between the two groups by the end of intervention, while no significant difference was noted in other blood indices.
Pomegranate extract supplements can help improve clinical symptoms and lower blood cell counts associated with inflammation in patients with allergic asthma.

Randomised Controlled Trial Asthma Pomegranate
In this study, 64 participants with mild to moderate allergic asthma were randomly divided into two groups: a control group which was given placebo capsules and an intervention group which was given pomegranate extract capsules. The intervention group was administered a dosage of 250 milligrams of pomegranate extract twice daily over a period of eight weeks. The clinical symptoms and blood cell counts of all the participants were measured before starting the intervention and post the completion of it.
The results of the study indicated that the group which was given pomegranate extract exhibited considerable improvement in clinical symptoms like shortness of breath and restrictions on activity, as compared to the control group. Additionally, the participants in the intervention group displayed a substantive drop in eosinophil, basophil, and neutrophil counts. Notably, there was a statistically significant difference in the neutrophil and eosinophil levels between the two groups, which suggests that pomegranate extract supplementation might have potential therapeutic benefits for asthma patients.
Pomegranate and its components could offer considerable potential as dietary supplements or supports in treatment for cardiovascular and non-cardiovascular diseases.

Review Article Cardiovascular Disease Pomegranate
The review examines a myriad of recent preclinical and clinical studies focusing on pomegranate. To harness the health benefits of pomegranate, different components were extracted and studied. These include juice from the fruit's edible arils, oil from the seeds, and bioactive products from the typically discarded peel. The research also considers advances in encapsulation and green extraction techniques to optimize the use of waste pomegranate products.
The studies suggest promising beneficial effects of pomegranate in diverse areas. Though challenges remain, such as limited oral bioavailability and uncertainty concerning the role of active metabolites, the collective findings offer crucial insight into the significant potential of pomegranate as a dietary supplement or co-therapy for a range of diseases, especially cardiovascular and non-cardiovascular ones.
Pomegranate and its by-products, particularly the peel, contain bioactive compounds with potential antimicrobial, anticancer and antiviral properties.

Review Article Anticancer Antimicrobial Antiviral
In the methodological approach of the study, a comprehensive review was undertaken to collate information on the bioactive components found within pomegranates and their by-products (aril, seed, and peel). The study emphasized the pomegranate peel's properties owing to its high content of the bioactive compounds. The aim was to elucidate the nutritional and functional aspects of pomegranates, particularly as a functional food.
The results outlined that pomegranates, especially their peel, contain bioactive compounds, including punicalagin, punicalin, ellagic acid, punicic acid, and anthocyanins. Therefore, they have potential functional properties such as antimicrobial, anticancer, and antiviral characteristics. These results suggest that pomegranates could be explored to develop nutraceutical or functional food products due to their profound properties. The peel of the pomegranate, specifically, showcases significant potential for development due to its higher bioactive compound content compared to other parts of the fruit.
Pomegranate consumption positively affects triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol levels.

Systematic Review Cholesterol Pomegranate Triglyceride
To investigate the impact of pomegranate on lipid profiles, a comprehensive database search was completed up until June 2023, aiming to identify related trials. Statistically, the researchers employed the estimated 95% confidence and the weighted mean difference to measure the variables, including triglycerides, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol. They employed a random-effects model for their analysis.
The meta-analysis revealed that pomegranate intake significantly reduces triglyceride levels. Still, it doesn't notably alter the total cholesterol concentrations. Additionally, consuming pomegranate seemed to have a diminishing impact on low-density lipoprotein cholesterol levels and an enhancing effect on high-density lipoprotein cholesterol levels.
