Background: Black garlic, also known as fermented garlic, is a useful food that may have therapeutic benefits. The aim of this study was to analyze the impact of fermented garlic and orlistat therapy on obese rats. Methods: A total of 40 male albino rats (245–250 g) were fed either an HFD (n = 32) or a normal diet (n = 8) for 6 weeks; therefore we randomly assigned the rats into: group I (normal diet), group II (HFD), groups III and IV (HFD with fermented garlic), and group V (orlistat for) 6 weeks. Two different dosages of fermented garlic (481.2 mg/kg and 963.3 mg/kg) were administered. Afterward, blood was collected, body weight was measured, and tissue was collected for further analysis. Results: Both the orlistat and black garlic groups showed a significant reduction in BMI, lipid profiles, and insulin levels compared with the baseline. The orlistat group showed significant elevation (p < 0.005) in body weight, organ weight, lipids, and liver parameters, with histopathological findings. The administration of black garlic improved the inflammatory markers with all other parameters. Conclusion: The fermented garlic and orlistat reinstated all of the investigated parameters significantly (p < 0.05), especially body weight and lipid profiles, and induced histopathological changes compared to the drug orlistat. Additionally, it showed anti-obesity-related therapeutic impacts compared with the orlistat drug. Black garlic provides a reliable and effective treatment for obesity compared to orlistat.

Functional and nutraceuticals products provide a bigger prospect to one’s health by permitting health costs and supporting economic growth in lower and middle developed countries. Because of this reason, mostly diversion of people is going towards functional food and these Phyto-based foods are turning out to be popular universal in the red to the number of statements from researchers for their therapeutic applications. Garlic is one of the ancient vegetables that is used worldwide in different aspects which includes seasoning, culinary purposes, flavoring, and medical purposes. The consumption of garlic word wide increases due to its convenience, tackiness, health benefits, and low side effects. Garlic has been utilized for thousands of years because of its rich active components, phytochemicals, and other Sulfur containing components. It has so much rich history to contribute to the food industry. It has been used as a food stabilizer to prevent the development of pathogens to the prevention of many diseases. The claimed vigor reimbursements of garlic are abundant, including, anticarcinogenic, antibiotic, anti-hypertensive, and cholesterol-lowering properties, the risk of cardiovascular disease lowering the effects of hypolipidemic, antithrombotic, anti-diabetic, antioxidant, antimicrobial, immunomodulatory, antimutagenic, and prebiotic activities. The present attempt of the chapter is to explore garlic history along with its active component’s involvement in the prevention of diseases and threats.

Black garlic, a fermented product of fresh garlic, has shown promising potential as a culinary ingredient and a medicinal remedy. This study examined the microbiological makeup, nutritional profile, and health advantages of black garlic to better understand its health-endorsing properties. Thermus, Corynebacterium, Streptococcus, and Brevundimonas were among the prominent taxa found when the microbial diversity in black garlic samples was investigated using Illumina MiSeq sequencing. This provided insight into the complex interactions between microorganisms during the fermentation process and clarified the distinctive qualities of black garlic. This study expanded its scope to include black garlic’s therapeutic potential, specifically in relation to liver function and hangovers caused by alcohol, in addition to its microbial complexity. Significant liver damage was revealed in alcohol-treated rats by serum biochemical indicators and histological stains; this damage was lessened by the administration of black garlic, particularly at higher dosages. Furthermore, black garlic showed hepatoprotective effects attributed to its high phenolic and flavonoid contents. These results offer a novel understanding of the medicinal qualities of black garlic as they lay out possibilities for the creation of functional drugs to treat alcohol-induced liver damage. Conclusively, black garlic’s diverse microbial composition also advances our knowledge of its nutritional makeup and health advantages. In summary, this research highlights the potential of black garlic as a flexible medical tool, having implications for both gastronomic and therapeutic uses.
