INTRODUCTION:

Aloe Vera is a plant native to tropical and subtropical regions and is well-known for its beneficial properties. The name "Aloe Vera" combines the Arabic word "Alloeh," meaning "shining bitter substance," with the Latin word "Vera," meaning "true." Its scientific name is Aloe barbadensis miller. This succulent plant resembles a shrub or small tree and is characterized by its thick, juicy, pea-green leaves, which can grow up to 20 inches long and 5 inches wide. The leaves are triangular and contain a translucent gel extracted from their midrib.

The gel can be processed in various ways. Sometimes, it's dried to make a concentrated form of Aloe Vera, while other times it’s mixed with water to create Aloe Vera juice. The leaves also produce a yellowish-green latex containing anthraquinones, compounds with laxative properties. Most of the world's Aloe Vera species are found in South Africa, Madagascar, and Arabia, among the many known species. Different species may have varying amounts of active compounds.

Aloe Vera has been used for centuries in herbal medicine, dating back to ancient times. Its gel is widely recognized for its soothing and healing properties, helping with skin issues such as cuts, burns, insect bites, and inflammation. It boasts numerous benefits, including anti-inflammatory, antiseptic, antibacterial, and antiviral effects. Aloe Vera promotes wound healing by retaining moisture, enhancing cell movement, increasing collagen production, and reducing inflammation. Typically, Aloe Vera plants grow to about 24-39 inches tall and reproduce through offshoots or cuttings. Some varieties have distinctive white spots on their leaves and are thick and meaty, varying in color from green to gray-green.^1,2

Researchers are exploring the bioactive components of Aloe Vera, such as acetylated mannans, polymannans, and anthraquinones. These components contribute to Aloe Vera's effectiveness in treating conditions like psoriasis, mouth sores, ulcers, and burns. Aloe Vera gel, rich in vitamins and amino acids, is also a popular ingredient in cosmetic products like moisturizers and sunscreens. It helps maintain hydrated, smooth, and firm skin. The gel is often applied directly from a fresh leaf to minor burns. The preparation of Aloe Vera products, including drying, boiling, or grinding, can affect the polysaccharides in the gel, potentially altering its physiological and pharmacological properties.³

Pharmacological Properties of Aloe Vera:

Aloe Vera, known scientifically as Aloe barbadensis miller, is renowned for its diverse pharmacological properties, which contribute to its wide use in traditional and modern medicine.

These antioxidants help neutralize free radicals and reduce oxidative stress, which can protect cells from damage and reduce the risk of chronic diseases associated with oxidative damage, such as cancer and cardiovascular diseases.

5. Immune System Support:

Aloe Vera has immune-modulating effects, enhancing the body's immune response. The plant's polysaccharides, especially acemannan, stimulate the production and activity of immune cells, such as macrophages and lymphocytes. This immune support can help the body better defend against infections and diseases.

6. Gastrointestinal Health:

Aloe Vera is known to promote digestive health. It acts as a laxative by stimulating bowel movements and improving digestion. The plant's mucilaginous gel also soothes and protects the gastrointestinal tract, which can help alleviate conditions such as irritable bowel syndrome (IBS) and acid reflux.

7. Skin Health:

Aloe Vera gel is widely used in skincare for its hydrating and soothing effects. It helps maintain skin moisture, reduces the appearance of fine lines and wrinkles, and can alleviate symptoms of skin conditions like eczema and psoriasis. The gel also has a cooling effect that soothes irritated or sunburned skin.^4,5,6

Chemicals:

Carbopol 940:

Carbopol 940 is utilized to increase viscosity, enhancing the gel's spreadability and consistency. It was chosen to evaluate the wound-healing effectiveness of the Aloe Vera herbal gel.

Glycerin:

Glycerin is effective in alleviating itching and adding radiance to skin and hair. When combined with Aloe Vera, it helps lock in moisture and gradually fade skin spots and rashes.

Method:

To prepare Aloe Vera gel, start by cutting fresh leaves from the Aloe Vera plant. Rinse the leaves thoroughly with cold water to remove any dirt and residual substances. Trim off the ends of the leaves and wipe away any yellow gel that may be present. Using a vegetable peeler or knife, carefully peel away the outer layer of the leaves. Next, scoop out the translucent inner gel with a spoon or knife and transfer it into a mortar and pestle. Homogenize the gel to achieve a smooth consistency. Place the homogenized gel into an ice cube tray and freeze it to solidify. Once the gel is frozen, mix in honey to enhance its properties. Finally, incorporate colouring agents and preservatives into the formulation to improve its appearance and extend its shelf life.^7,8
