Diabetes mellitus is a metabolic disease manifested by hyperglycemia, leading to critical health challenges in the kidneys, eyes, nerves, and cardiovascular system. Aloe vera (Aloe barbadensis miller), a traditionally used herbal plant for treating various diseases, contains abundant bioactive compounds like alkaloids, flavonoids, acemannans, anthraquinones, chromones, anthrones, enzymes, vitamins, and minerals. These compounds are responsible for its diverse biological activities, including antimicrobial, anticancer, antidiabetic, anti-inflammatory, antioxidant, and hypolipidemic etc. This review primarily focuses on diabetes treatment through enzyme inhibition and modulation of metabolic parameters, with additional emphasis on diabetic complications including, the wound healing efficacy of Aloe vera. This study aims to evaluate the potential of Aloe vera in managing diabetes and minimizing the chances of diabetes-related organ damage. It was done by inhibition of several enzymes, including α-glucosidase, α-amylase, dipeptidyl peptidase-4, pancreatic lipase, sucrase, and maltase enzymes, both in vivo and in vitro. The previous research revealed that administrating various doses of Aloe vera-based extracts via orally and non-orally routes in streptozotocin-induced diabetes offered metabolic regulation of signaling pathways like blood sugar, insulin, lipid profile, body weight, oxidative stress, TNF-α, and IL-6 levels. Moreover, clinical data have confirmed Aloe vera’s potential in diabetic wound healing by promoting tissue regeneration mechanisms like angiogenesis, fibrinogenesis, collagen synthesis, and inflammation to reduce lesion size. These therapeutic properties highlight the hypoglycemic nature of Aloe vera, promising its potential for future clinical use as an alternative for diabetes treatment. Graphical Abstract

Aloe vera (Aloe barbadensis Miller) represents a rich natural source of water, minerals, polysaccharides, vitamins, phenolic compounds and bioactive molecules that exert multiple health-promoting effects relevant to athletic performance. Its high content of water and minerals (magnesium, calcium, potassium) supports hydration and electrolyte balance during physical activity. At the same time, polysaccharides, especially acemannan, contribute to tissue regeneration, muscle recovery, immune modulation and gastrointestinal protection. Antioxidant compounds reduce exercise-induced oxidative stress, potentially improving recovery and limiting inflammatory damage. Aloe vera-based beverages, including leaf juices and fermented formulations, offer a practical and palatable vehicle for delivering these bioactives. In addition to supporting gut integrity and reducing symptoms such as reflux and heartburn, Aloe vera supplementation may enhance nutrient absorption and modulate glucose metabolism, contributing to better metabolic stability during exercise. The increasing commercial interest in natural functional beverages highlights the relevance of Aloe vera as a nutraceutical candidate for athletes. This review explores the multiple benefits of Aloe leaf derivatives, bridging traditional medicine and evidence-based applications for metabolic health (gastrointestinal comfort, hydration, antioxidant defence and post-exercise recovery). However, further clinical studies are needed to fully define dosage, efficacy and mechanisms of action.

Background Acetaminophen overdose is a leading cause of drug-induced acute liver damage, underscoring the urgent need for accessible hepatoprotective therapies. This study evaluated the hepatoprotective effects of Aqueous Aloe vera gel extract on acetaminophen-induced liver damage in adult male Albino Wistar rats. Methodology Liver Damage was induced in Albino Wistar rats by oral administration of acetaminophen (750 mg/kg). The rats were divided into six groups: normal control, negative control, positive control (silymarin 50 mg/kg), and three treatment groups receiving Aloe vera gel extract at doses of 250 mg/kg, 500 mg/kg, and 1000 mg/kg. Body and liver weight, hematological, biochemical and oxidative stress parameters and liver histology were assessed after 7 days of treatment. Results Treatment with Aloe vera gel extract demonstrated dose-dependent hepatoprotective, anti-inflammatory and antioxidant effects with the 1000 mg/kg dose exhibiting efficacy comparable to silymarin. Higher doses (1000 mg/kg) significantly increase both the body weight and weight of the liver (p = 0.0265 and p = 0.0061); decreased the white blood cell count (p = 0.0034) and also improved hematological parameters. The extract at 1000 mg/kg also enhanced antioxidant status by reducing MDA levels (p < 0.0001) while increasing SOD (p < 0.0001) and catalase activities. Histological examination also showed that higher doses of the aqueous Aloe vera gel extract restored liver histoarchitecture, with clearly defined nuclei and cell borders. Conclusion This study demonstrates that the aqueous Aloe vera gel extract mitigates acetaminophen-induced hepatotoxicity through antioxidant, anti-inflammatory, and regenerative mechanisms. At 1000 mg/kg, it restored hepatic histoarchitecture, haematological homeostasis, normalized liver function biomarkers, and suppressed oxidative stress, rivalling silymarin in efficacy. The observed improvements in liver histology, haematological parameters, and antioxidant biomarkers indicate Aloe vera’s therapeutic potential, likely mediated through its bioactive constituents with antioxidant and anti-inflammatory properties. Further research is recommended to understand its mechanism of action, long-term and potential clinical applications.

Aloe Vera (Aloe barbadensis Miller), a historically revered medicinal plant, has garnered great scientific attention due to its polysaccharide-rich bioactive compounds with significant therapeutic potential. This review examines the role of Aloe Vera polysaccharides as therapeutic agents in biomedical applications, highlighting their benefits as well as the risks. Traditionally recognized for its anti-inflammatory and antimicrobial effects, which are very important in wound healing, the Aloe Vera relies on its polysaccharides, which confer immunomodulatory, antioxidant, and tissue-regenerative properties. These compounds have shown promise in various applications, including skin repair, tissue engineering scaffolds, and antiviral therapies, with their delivery being facilitated via gels, thin films, or oral formulations. This review explores also their mechanisms of action and applications in modern medicine, including in the development of topical gels, dietary supplements, and innovative delivery systems such as thin films and scaffolds. Despite the promising benefits, the review addresses the possible side effects too, including allergic reactions, gastrointestinal disorders, and drug interactions, emphasizing the importance of understanding these risks for their safe clinical use. Assessing both the advantages and challenges of Aloe Vera polysaccharide medical use, this review contributes to the ongoing dialog regarding the integration of natural products into therapeutic practices, ultimately supporting informed decisions regarding their clinical application.

Background: Aloe vera, often dubbed the "plant of immortality," has been cherished for its healing properties throughout history.

The present study aimed to conduct a comparative investigation of the biological properties of phenolic and polysaccharide extracts obtained using an ultrasound-assisted technique from Aloe vera gel and their effects on each stage of the wound healing process in in vitro experimental models. HPLC analysis showed that the phenolic extract contained aloin, ferulic, and caffeic acid, as well as quercetin dihydrate, as major compounds. Capillary zone electrophoresis indicated the prevalence of mannose and glucose in the polysaccharide extract. Cell culture testing revealed the anti-inflammatory properties of the phenolic extract at a concentration of 0.25 mg/mL through significant inhibition of pro-inflammatory cytokines—up to 28% TNF-α and 11% IL-8 secretion—in inflamed THP-1-derived macrophages, while a pro-inflammatory effect was observed at 0.5 mg/mL. The phenolic extract induced 18% stimulation of L929 fibroblast proliferation at a concentration of 0.5 mg/mL, enhanced the cell migration rate by 20%, and increased collagen type I synthesis by 18%. Moreover, the phenolic extract exhibited superior antioxidant properties by scavenging free DPPH (IC50 of 2.50 mg/mL) and ABTS (16.47 mM TE/g) radicals, and 46% inhibition of intracellular reactive oxygen species (ROS) production was achieved. The polysaccharide extract demonstrated a greater increase in collagen synthesis up to 25%, as well as antibacterial activity against Staphylococcus aureus with a bacteriostatic effect at 25 mg/mL and a bactericidal one at 50 mg/mL. All these findings indicate that the phenolic extract might be more beneficial in formulations intended for the initial phases of wound healing, such as inflammation and proliferation, while the polysaccharide extract could be more suitable for use during the remodeling stage. Moreover, they might be combined with other biomaterials, acting as efficient dressings with anti-inflammatory, antioxidant, and antibacterial properties for rapid recovery of chronic wounds.
