The present review explains therapeutic and pharmaceutical potential of Aloe vera a well-known plant grows in semi-arid climate of tropical and subtropical regions. This article emphasizes important uses of A. vera constituents as dietary nutraceutical, medicinal, and therapeutic potential. Plant is cultivated for agricultural and medicinal and decoration purposes for indoors as a potted plant. Plant is a good depository of chemical constituents which display a very wide array of biological activities such as anticancer, antiparasitic, antidiabetic, anti-inflammatory, anti-arthritic, antiparasitic, antitumor, antioxidant, chemopreventive, hepatoprotective, and gastroprotective. Plant is used to prepare skin protective/care gels mainly for soothing, moisturizing, and wound healing. Thick watery plant sap works are added as key ingredient in many beauty products. Plant leaves are used to generate aroma, beverages, skin lotion, cosmetics, or ointments for minor burns. Plant contains vitamins, enzymes, minerals, sugars, lignin, saponins, salicylic acids, and amino acids as main ingredients. Plant is a good source of Vitamins A, C, and E, which are antioxidants. It also contains Vitamin B12, folic acid, and choline watery juicy of A. vera leaf which contains important minerals such as calcium, chromium, copper, selenium, magnesium, manganese, and potassium. Plant ingredients were found active against gingivitis, psoriasis, and used for herbal therapy in inflammatory bowel disease. A. vera contains important fatty acids mainly steroids such as cholesterol, campesterol, β-sitosterol, and lupeol. Aloin and emodin act as analgesics, antibacterials, and antivirals while lupeol shows antiseptic and analgesic properties. It also contains auxins and gibberellin hormones that help in wound healing and have anti-inflammatory action. Saponins that are the soapy substances display cleansing and antiseptic properties.

The aim of this study was to evaluate evidence for the efficacy of aloe vera on managing prediabetes and early non-treated diabetes mellitus. We performed a systematic search of PubMed, Embase, and Cochrane Central Register of Controlled Trials until 28 January 2016. A total of five randomized controlled trials (RCTs) involving 415 participants were included. Compared with the controls, aloe vera supplementation significantly reduced the concentrations of fasting blood glucose (FBG) (p = 0.02; weighed mean difference [WMD]: −30.05 mg/dL; 95% confidence interval [CI]: −54.87 to −5.23 mg/dL), glycosylated hemoglobin A1c (HbA1c) (p < 0.00001; WMD: −0.41%; 95% CI: −0.55% to −0.27%), triglyceride (p = 0.0001), total cholesterol (TC) (p < 0.00001), and low density lipoprotein-cholesterol (LDL-C) (p < 0.00001). Aloe vera was superior to placebo in increasing serum high density lipoprotein-cholesterol (HDL-C) levels (p = 0.04). Only one adverse event was reported. The evidence from RCTs showed that aloe vera might effectively reduce the levels of FBG, HbA1c, triglyceride, TC and LDL-C, and increase the levels of HDL-C on prediabetes and early non-treated diabetic patients. Limited evidence exists about the safety of aloe vera. Given the small number and poor quality of RCTs included in the meta-analysis, these results are inconclusive. A large-scale, well-designed RCT is needed to further address this issue.

Background: Applying a cooling treatment from outside the body is one way to lower fever in children. Midwives commonly perform a warm water compress in their care, but it is considered less effective. Thus, compress with Aloe Vera Barbadensis Miller is proposed in this study as an alternative treatment. Objective: To examine the effect of Aloe Vera Barbadensis Miller compress in reducing body temperature in children with fever. Methods: This was a quasi-experimental study with pretest and posttest with control group design. Forty children were recruited, with twenty of them assigned in each group. Purposive sampling was performed to select the sample. A digital rectal thermometer was used to measure the temperature. Independent t- test and paired test were used for data analysis. Results: Findings showed that the Aloe Vera compress group showed a higher decrease of body temperature compared to the warm water compress group. The difference of body temperature after 20 minutes in the experiment group was 1.435 while in the control group was only 1.085. There were statistically significant differences in body temperature between the experiment and control group (p=0.013). Conclusion: Aloe Vera Barbadensis Miller compress is an effective alternative therapy in reducing body temperature in children with fever.  It is recommended for midwives to apply this intervention to reduce body temperature significantly.

Disaccharidases are a group of enzymes of the small intestinal brush border, that are essential for degradation of disaccharides (sucrose, lactose, maltose, isomaltose, trehalose) into monosaccharides, which are then absorbed from the gastrointestinal tract. Their deficiency may occur at any stage o …

Aloe vera has been used as folk medicine for a host of therapeutic indications of which the inner gel is the component extensively used and studied. Proponents of the use of this plant suggest that it is easily available, economical, and have fewer side effects compared to commercial drug compounds. However, the active constituents and their exact mechanisms have yet to be fully elucidated. This review focuses on the identification of the active constituents and their functional mechanism in the areas of anti-diabetic, anti-inflammatory, wound healing, and antibacterial. Preliminary evidence was found to support the antidiabetic effect which extended to the early stages of the disease with no adverse effects at the dosages used. Although topical application for its anti-inflammatory effect may be delayed and minute, oral administration has shown a significant response. However, too high a dose has been linked with an initial inflammatory reaction. Favorable response to the gel has also been demonstrated to support the use of A. vera in wound-healing and as an antibacterial agent, although limited to simple, uncomplicated wounds. Different active constituents such as acemannan and aloin have been suggested for the effects of the plant and this may be interpreted as synergism among different compounds rather than the action of a single compound. Until robust evidence is available, the plant should only be used as an adjunct to other well-established evidence-based treatment modalities.

The co-administration of absorption enhancing agents with macromolecular drugs (e.g., protein and peptide drugs) has been identified as a means to improve the oral bioavailability of these drugs. Absorption-enhancing agents of natural origins have received a great deal of attention due to their sustainable production, in support of green chemistry. In previous studies, certain parts of the Aloe vera leaf (e.g., gel and whole leaf extract) have shown a potential to enhance drug permeation across the intestinal epithelial barrier. The mechanism of the drug-absorption-enhancement action and the capacity for absorption-enhancement of the A. vera gel and whole leaf, were investigated in this study. A clear decrease in transepithelial electrical resistance (TEER) of Caco-2 cell monolayers exposed to A. vera gel and wholeleaf extract, in various concentrations, indicated the opening of tight junctions between the epithelial cells. The transport of Fluorescein isothiocyanate (FITC)-dextran, with a molecular weight of 4 kDa (FD-4), could be enhanced across the Caco-2 cell monolayers, by the A. vera gel and whole-leaf extract, but not the FITC-dextran with larger molecular weights (i.e., 10, 20, and 40 kDa), which indicated a limited drug absorption enhancement capacity, in terms of the molecular size. Accumulation of FD-4 between the Caco-2 cells (and not within the cells), after treatment with the A. vera gel and whole-leaf extract was shown with a confocal laser scanning microscopy (CLSM) imaging, indicating that the paracellular transport of FD-4 occurred after the interaction of the A. vera gel and whole-leaf extract, with the epithelial cell monolayers. Furthermore, changes in the F-actin distribution in the cytoskeleton of the Caco-2 cell monolayers was observed by means of a fluorescence staining, which confirmed tight junction modulation as the mechanism of action for the absorption enhancement effect of the A. vera gel and whole-leaf extract.
