This article contains findings obtained from research on animals:
- The results from animal research studies should not be directly applied to humans and the results may not generalise to the human population.
- There may be significant differences between species in terms of physiology, physiology, and pharmacology, as well as differences in the way diseases and treatments are modelled in animals.
- Any conclusions drawn from animal research should be considered with caution and in the context of other types of research studies such as observational studies, clinical trials, and reviews of the literature.
Insights & Discussion
Pomegranate rind extract has been found to decrease pain and inflammation, suggesting it could contribute to treating rheumatoid arthritis.
The researchers tested the effects of various doses of pomegranate rind extract on Wistar rats within established models of pain and inflammation, such as eddy's hot plate-induced algesia, carrageenan, and Complete Freund's adjuvant-induced models. Indomethacin was also evaluated for comparison. Researchers used bioactive compounds such as phenolics and flavanoids, both of which are known for their potent antioxidant activity.
The results observed showed that a dose of 200 mg/kg of pomegranate led to a clear reduction in paw swelling in the rats in both inflammation models. The data further revealed an increase in pain threshold. Through these results, it was determined that pomegranate extract acts to reduce pain and inflammation by inhibiting the activation of a number of inflammatory markers. Furthermore, this study presents the first report on the inhibitory mechanism of these markers by pomegranate rind extract, which is enriched with tannins and flavanoids.

Randomised Controlled Trial PCOS Pomegranate Testosterone
In the methodology, the study employed a randomized controlled trial which involved 44 participants. The women, aged between 18 and 40 years, had all been diagnosed with polycystic ovary syndrome and had a body mass index exceeding 25 kg/m. They were randomly divided, with one group consuming 45 ml/day of concentrated pomegranate juice and the other group receiving no intervention. A variety of biomarkers for sex hormones, inflammation, and oxidative stress were measured before starting the trial and again after eight weeks.
Further discussion of the results revealed a significant decrease in testosterone levels among the overweight and obese women with polycystic ovary syndrome who took concentrated pomegranate juice over the eight week period, in contrast to those in the control group. Apart from testosterone, no significant changes were observed for luteinizing hormone, sex hormone-binding globulin levels or for markers of inflammation and oxidative stress between the two groups.
Pomegranate extract supplements can help improve clinical symptoms and lower blood cell counts associated with inflammation in patients with allergic asthma.

Randomised Controlled Trial 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.

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 peel extract, along with a calorie deficit diet, could improve risk factors of metabolic syndrome and reduce fatty liver in patients with non-alcoholic fatty liver disease.

Randomised Controlled Trial NAFLD Pomegranate Peel
In the first phase, the research involved the hydro-alcoholic extraction of the peel of 750 kilograms of pomegranate using the soaking method. The second phase saw patients with non-alcoholic fatty liver disease divided into two groups - a placebo group and a pomegranate peel capsule group. Both groups followed a diet with a 500 kcal deficit for eight weeks. Aspects like intolerance to the treatment, participants' dietary intake, their lipid and glycemic profiles, blood pressure, body composition, insulin resistance indexes and changes in fatty liver disease evaluated through elastography were monitored.
Further, the study reported substantial decreases in multiple indicators such as body weight, waist circumference, body mass index, body fat index, trunk fat, blood pressure, total cholesterol, triglyceride levels, LDL cholesterol, fat free mass, and fasting blood sugar in the group that took pomegranate peel capsules compared to the placebo group. Meanwhile, HDL cholesterol and liver steatosis and stiffness saw improvement. No significant differences, however, were found in the insulin and homeostatic model assessment for insulin resistance between the two groups.
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.
