#ESSENTIAL ANATOMY 3 FREE TRIAL SKIN#
11Įffects on skin exposure to UV and gamma radiation: Aloe vera gel has been reported to have a protective effect against radiation damage to the skin. 10 An increased synthesis of hyaluronic acid and dermatan sulfate in the granulation tissue of a healing wound following oral or topical treatment has been reported. Due to this, it accelerated wound contraction and increased the breaking strength of resulting scar tissue. 9 Aloe gel not only increased collagen content of the wound but also changed collagen composition (more type III) and increased the degree of collagen cross linking.
Healing properties: Glucomannan, a mannose-rich polysaccharide, and gibberellin, a growth hormone, interacts with growth factor receptors on the fibroblast, thereby stimulating its activity and proliferation, which in turn significantly increases collagen synthesis after topical and oral Aloe vera. Saponins that are the soapy substances form about 3% of the gel and have cleansing and antiseptic properties. Lignin, an inert substance, when included in topical preparations, enhances penetrative effect of the other ingredients into the skin. It also contains salicylic acid that possesses anti-inflammatory and antibacterial properties. Others: It provides 20 of the 22 human required amino acids and 7 of the 8 essential amino acids. Hormones: Auxins and gibberellins that help in wound healing and have anti-inflammatory action. All these have anti-inflammatory action and lupeol also possesses antiseptic and analgesic properties. Aloin and emodin act as analgesics, antibacterials and antivirals.įatty acids: It provides 4 plant steroids cholesterol, campesterol, β-sisosterol and lupeol. 7, 8Īnthraquinones: It provides 12 anthraquinones, which are phenolic compounds traditionally known as laxatives. Recently, a glycoprotein with antiallergic properties, called alprogen and novel anti-inflammatory compound, C-glucosyl chromone, has been isolated from Aloe vera gel. Acemannan, a prominent glucomannan has also been found. The most prominent monosaccharide is mannose-6-phosphate, and the most common polysaccharides are called glucomannans. These are derived from the mucilage layer of the plant and are known as mucopolysaccharides. Sugars: It provides monosaccharides (glucose and fructose) and polysaccharides: (glucomannans/polymannose). They are essential for the proper functioning of various enzyme systems in different metabolic pathways and few are antioxidants. Minerals: It provides calcium, chromium, copper, selenium, magnesium, manganese, potassium, sodium and zinc. Bradykinase helps to reduce excessive inflammation when applied to the skin topically, while others help in the breakdown of sugars and fats. Antioxidant neutralizes free radicals.Įnzymes: It contains 8 enzymes: aliiase, alkaline phosphatase, amylase, bradykinase, carboxypeptidase, catalase, cellulase, lipase, and peroxidase. It also contains vitamin B12, folic acid, and choline. Vitamins: It contains vitamins A (beta-carotene), C and E, which are antioxidants.
3Īctive components with its properties: Aloe vera contains 75 potentially active constituents: vitamins, enzymes, minerals, sugars, lignin, saponins, salicylic acids and amino acids. Inside the rind are vascular bundles responsible for transportation of substances such as water (xylem) and starch (phloem). 3) The outer thick layer of 15–20 cells called as rind which has protective function and synthesizes carbohydrates and proteins. 2) The middle layer of latex which is the bitter yellow sap and contains anthraquinones and glycosides.
Each leaf is composed of three layers: 1) An inner clear gel that contains 99% water and rest is made of glucomannans, amino acids, lipids, sterols and vitamins. The plant has triangular, fleshy leaves with serrated edges, yellow tubular flowers and fruits that contain numerous seeds.
