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.

Aloe vera has a long history of popular and traditional use. It is used in traditional Indian medicine for constipation, colic, skin diseases, worm infestation, and infections (Heber 2007). It is also used in Trinidad and Tobago for hypertension (Lans 2006) and among Mexican Americans for the treatment of type 2 diabetes mellitus (DM; Coronado et al. 2004). In Chinese medicine, it is often recommended in the treatment of fungal diseases (Heber 2007). In Western society, Aloe vera is one of the few herbal medicines in common usage, and it has found widespread use in the cosmetic, pharmaceutical, and food industries. In the case of health, the therapeutic claims for the topical and oral application of Aloe vera cover a wide range of conditions, but few claims have been the subject of robust clinical investigation. The conditions for which clinical trials of Aloe vera have been conducted include skin conditions, management of burn and wound healing, constipation, DM, and gastrointestinal disorders.

Aloe vera still needs to be researched more for its use in treating diabetes, but preliminary results show that it could help lower both fasting glucose and A1C.

High-fat diet alone or in combination with high fructose has been known to induce diabetes, obesity, hypertension, and immune dysfunction. The study evaluates the role of Aloe vera in fat-rich and high fructose diet-induced (FRHFD) hyperglycemias in addition to testicular and splenic morphology in mice. Twenty BALB/c Mice were randomly distributed into four groups (n=5). The groups were fed on a normal diet, FRHFD, FRHFD + 10 g Aloe vera , and FRHFD + 20 g Aloe vera for 10 weeks. All the mice were sacrificed a day after the 10 weeks of treatment. The result showed that mice fed on FRHFD plus Aloe vera had a significantly lower (p

Pesticide exposure can pose a serious risk to nontarget animals. Cartap is being broadly used in agricultural fields. The toxic effects of cartap on the levels of hepatotoxicity and neurotoxicity have not been properly studied in mammalian systems. Therefore, the present work focused on the effect of cartap on the liver and brain of Wistar rats and made an assessment of the ameliorating potential of A. vera. The experimental animals were divided into 4 groups, comprising six rats in each: Group 1—Control; Group 2—A. vera; Group 3—Cartap; and Group 4—A. vera + Cartap. The animals orally given cartap and A. vera were sacrificed after 24 h of the final treatment and histological and biochemical investigations were conducted in liver and brain of Wistar rats. Cartap at sublethal concentrations caused substantial decreases in CAT, SOD, and GST levels in the experimental rats. The activity levels of transaminases and phosphatases in cartap group were also found to be substantially altered. The AChE activity was recorded as decreasing in RBC membrane and brain of the cartap-treated animals. The TNF-α and IL-6 level in serum were increased expressively in the cartap challenged groups. Histological investigation of liver showed disorganized hepatic cords and severely congested central veins due to cartap. However, the A. vera extract was observed to significantly protect against the effects of cartap toxicity. The protective impact of A. vera against cartap toxicity may be due to the existence of antioxidants in it. These findings suggest that A. vera may be developed as a potential supplement to the appropriate medication in the treatment of cartap toxicity.

Introduction: Diabetics usually suffer from chronic complications, including microvascular and macrovascular disorders. The capillaries supplying the sexual organs affect normal sexual functions. The erectile process has been shown to be impaired in diabetics. Vascular damage in diabetics may be associated with decreased testosterone production, sperm count, testicular weight, and seminiferous tubule diameter. In this study, we investigated the effects of Aloe vera gel extract (from Sistan and Baluchistan in Iran) on male genital in streptozocin-induced diabetic rats. Methods: Of twenty-four male Wistar rats, diabetes was induced in 12 rats by intraperitoneal injection of a single dose of STZ. The rats were divided into four groups. The first and third groups received saline (NaCl) daily by gavage. The second and fourth groups received aloe vera gel extract daily by gavage. The treatments were continued for 30 days. At the end of the treatment period, blood samples were collected and serum glucose and testosterone levels were measured by photometric methods. Histological examinations were performed on the prostate and testes. Results: Mean weight index, serum levels of glucose and testosterone, mean sperm count, germline thickness, and seminiferous tubule diameter improved significantly in the diabetes +Aloe vera group. Conclusion: We concluded that consumption of Aloe vera gel extract improved sexual complications in type 1 diabetic rats.
