Authors J. Hamman,
many of the health benefits associated with Aloe vera have been attributed to the polysaccharides contained in the gel, biological activities include promotion of wound healing, antifungal activity, hypoglycemic or antidiabetic effects anti-inflammatory, anticancer, immunomodulatory and gastroprotective properties, A. vera to enhance the intestinal absorption and bioavailability of co-administered compounds as well as enhancement of skin permeation, A. vera gel powder as an excipient in sustained release pharmaceutical dosage forms, aloe vera has diverse biological activities such as wound healing, enhancement of the reticuloendothelial system, stimulation of the immune system, treatment of tumors and effects on the hematopoietic system, biological activities should be assigned to a synergistic action of the compounds contained therein rather than a single chemical substance, aloe gel is source of functional foods and as an ingredient in other food products, for the production of gel-containing health drinks and beverages, cosmetic and toiletry industry, Important pharmaceutical properties that have recently been discovered for both the A. vera gel and whole leaf extract include the ability to improve the bioavailability of co-administered vitamins in human subjects, Aloe vera gel include the ability to improve the bioavailability of co-administered vitamins in human subjects, polysaccharides in A. vera gel have therapeutic properties such as immunostimulant, anti-inflammatory effects, wound healing, promotion of radiation damage repair, anti-bacterial, anti-viral, anti-fungal, anti-diabetic and anti-neoplastic activities, stimulation of hematopoiesis and anti-oxidant effects, two maloyl glucans, namely veracyl glucan B and C, were each individually evaluated for biological activities it was found that veracyl glucan B demonstrated high anti-inflammatory and anti-proliferation effects, while veracyl glucan C exhibited significant cell proliferative and anti-inflammatory activities, Anti-oxidant effects of aloe vera, Glutathione peroxidase activity, superoxide dismutase enzymes and a phenolic anti-oxidant were found to be present in A. vera gel, which may be responsible for these anti-oxidant effects. It was shown in two cell-free in vitro systems and by incubation with inflamed colorectal mucosal biopsies that A. vera gel has a dose-dependent antioxidant effect. The cell-free techniques used in this study assessed the scavenging of both superoxide and peroxyl radicals, aloe vera has Antimicrobial activities, activity of A. vera inner gel against both Gram-positive and Gram-negative bacteria has been demonstrated by several different methods, anthraquinones isolated from the exudate of A. vera have shown wide antimicrobial activity, antibacterial activity of emodin against Escherichia coli was proposed to be mediated through inhibition of solute transport in membranes, many anthraquinones have shown antiviral and/or virucidal effects on enveloped viruses, Aloe Vera
