The benefits and healing properties of aloe
Aloe Vera contains 75 potentially active ingredients: vitamins, enzymes, minerals, sugars, lignin, saponins, salicylic acids and amino acids. 
Vitamins: The presence of vitamins with antioxidant abilities is especially important - these are ascorbic acid, tocopherol, vitamin A and group B. It also contains vitamin B12, folic acid and choline. Antioxidants neutralizes free radicals.
Enzymes: contains 8 enzymes: aliase, alkaline phosphatase, amylase, bradykinase, carboxypeptidase, catalase, cellulase, lipase and peroxidase. Bradykinase helps reduce excessive inflammation when applied topically to the skin, while others help break down sugars and fats.
Minerals: calcium, chromium, copper, selenium, magnesium, manganese, potassium, sodium and zinc. They are necessary for the proper functioning of various enzyme systems on different metabolic pathways, and only a few are antioxidants.
Sugar: monosaccharides (glucose and fructose) and polysaccharides: (glucomannans / polymanose). They are obtained from the mucous membrane of a plant and are known as mucopolysaccharides. The most famous monosaccharide is mannose-6-phosphate, and the most common polysaccharides are called glucomannans [beta- (1,4) -acetylated mannans]. Also found was Acemannan, the famous glucomannan. Recently, an anti-allergic glycoprotein called alprogen and a new anti-inflammatory compound, C-glucosylchromone, have been isolated from aloe vera gel. , 
Anthraquinones: 12 anthraquinones have been found which are phenolic compounds traditionally known as laxatives. Aloin and emodin act as analgesics, antibacterial and antiviral.
Fatty acids: contains 4 plant steroids; cholesterol, campesterol, β-sysosterol and lupeol. All of them have anti-inflammatory effects, and lupeol also has antiseptic and analgesic properties.
Hormones: auxins and gibberellins that help in wound healing and have anti-inflammatory effects.
Others: contains 20 of 22 amino acids necessary for the person and 7 of 8 irreplaceable amino acids. It also contains salicylic acid, which has anti-inflammatory and antibacterial properties. Lignin, an inert substance, when it is part of topical preparations, enhances the penetration of other components into the skin. Saponins, which are soapy substances, make up about 3% of the gel and have cleansing and antiseptic properties.
Mechanism of action
Healing properties: glucomannan, a mannose-rich polysaccharide, and gibberellin, growth hormone, interact with growth factor receptors on fibroblast, thereby stimulating its activity and proliferation, which, in turn, significantly increases collagen synthesis after local and oral use of Aloe vera.  Aloe not only increased the collagen content in the wound, but also changed the composition of collagen (more than type III) and increased the degree of cross-linking of collagen. Due to this, he accelerated the contraction of the wound and increased the strength of the resulting scar tissue. An increased synthesis of hyaluronic acid and dermatan sulfate in the granulation tissue of a healing wound after oral or local treatment has been reported. 
Effect on the effects of ultraviolet and gamma radiation on the skin. Aloe vera has been reported to have a protective effect against radiation damage to the skin. ,  The exact role is unknown, but after applying aloe vera, an antioxidant protein metallothionein is formed in the skin, which removes hydroxyl radicals and prevents the suppression of superoxide dismutase and glutathione peroxidase in the skin. It reduces the production and release of immunosuppressive cytokines derived from skin keratinocytes, such as interleukin-10 (IL-10), and therefore prevents UV-induced suppression of delayed-type hypersensitivity. 
Anti-inflammatory effect: aloe vera inhibits the cyclooxygenase pathway and reduces the production of prostaglandin E2 from arachidonic acid. Recently, a new anti-inflammatory compound called C-glucosylchromone has been isolated from gel extracts.
Impact on the immune system: Alprogen inhibits the influx of calcium into mast cells, thereby inhibiting the release of histamine and leukotriene from mast cells by antigen-antibody-mediated antibodies. In a study in mice that had previously been implanted with mouse sarcoma cells, acemannan stimulates the synthesis and release of interleukin-1 (IL-1) and tumor necrosis factor from macrophages in mice, which in turn triggered an immune attack that led to necrosis and cancer cell regression.  Some low molecular weight compounds are also able to inhibit the release of active oxygen radicals from activated human neutrophils. 
Laxatives: Anthraquinones present in the skin of Aloe are a strong laxative. Increases the water content in the intestines, stimulates the secretion of mucus and increases intestinal motility. 
Antiviral and antitumor activity: these actions may be associated with indirect or direct effects. The indirect effect is due to stimulation of the immune system, and the direct effect is due to anthraquinones. Anthraquinone aloin inactivates various enveloped viruses, such as herpes simplex, chickenpox and influenza.  Recent studies have shown that the polysaccharide fraction inhibits the binding of benzopyrene to rat primary hepatocytes, thereby preventing the formation of cancer-causing benzopyrene-DNA adducts. The induction of glutathione S-transferase and the inhibition of the tumor-stimulating effects of phorbol-myristin acetate have also been reported, indicating a possible benefit from using aloe gel in cancer chemoprevention. , 
Moisturizing and anti-aging effect: mucopolysaccharides help bind moisture to the skin. Aloe stimulates fibroblasts, which produce collagen and elastin fibers, making the skin more elastic and less wrinkled. It also has a binding effect on superficial exfoliating epidermal cells, gluing them together, which softens the skin. Amino acids also soften hardened skin cells, and zinc acts as an astringent, narrowing the pores. Its moisturizing effect has also been studied in the treatment of dry skin associated with occupational exposure, when aloe vera gel gloves improve skin integrity, reduce the appearance of fine wrinkles and reduce erythema.  It also has an anti-acne effect.
Antiseptic effect: Aloe Vera contains 6 antiseptic agents: lupeol, salicylic acid, urea nitrogen, cinnamic acid, phenols and sulfur. All of them have an inhibitory effect on fungi, bacteria and viruses.
Thus, aloe with gastritis is used, due to its healing abilities:
- regeneration (restoration) of the internal tissues of the stomach;
- the destruction of pathogens (antimicrobial effect), a decrease in the activity of E. Coli;
- strengthening immunity;
- inhibition of the inflammatory process;
- healing of erosion, ulcers.
Plant components that have anti-inflammatory effects, at the same time have an analgesic effect, and also help damaged tissues recover.
In case of acidity disorders, aloe activates regeneration, blocks atrophic processes, relieves bloating, and generally normalizes the function of the digestive organs.
