Overview
Aloe vera is one of the most widely used medicinal plants in the world, cultivated for over 6,000 years. The clear gel from its succulent leaves contains over 75 active compounds including polysaccharides, vitamins, minerals, enzymes, and amino acids. Aloe vera is most celebrated for its skin-healing, anti-inflammatory, and wound-healing properties, but also has significant benefits for digestive health, immune function, and blood sugar regulation. It is one of the most commercially important medicinal plants globally.
Traditional Use
Aloe vera has been used medicinally for over 6,000 years. Ancient Egyptians called it the "plant of immortality" and used it in embalming and as a medicine for skin conditions and infections. The Ebers Papyrus (1550 BC) describes aloe vera preparations for skin diseases. Ancient Greeks and Romans used aloe vera for wounds, hair loss, and digestive complaints. Alexander the Great reportedly conquered the island of Socotra to secure aloe vera supplies for his army's wounds. In Ayurvedic medicine, aloe vera (Kumari) is used for digestive disorders, liver conditions, and as a rejuvenating tonic.
Key Active Compounds
Acemannan
A complex polysaccharide that is the primary immunomodulatory compound in aloe vera gel. Stimulates macrophage activity, promotes wound healing, and has antiviral properties.
Aloin (Barbaloin)
An anthraquinone found in the latex layer (NOT the gel). Has strong laxative effects. The gel contains minimal aloin; whole-leaf products may contain more.
Aloesin & Aloin B
Chromone compounds with anti-inflammatory and antioxidant properties that contribute to aloe's skin-soothing effects.
Vitamins C, E, and Beta-carotene
Antioxidant vitamins that protect skin cells from oxidative damage and support collagen synthesis.
Enzymes (Bradykinase)
Reduces inflammation when applied topically by breaking down bradykinin, a pain-inducing compound.
Evidence-Based Benefits
Wound healing and burn treatment
Strong evidenceMultiple clinical trials confirm aloe vera gel accelerates healing of first and second-degree burns, surgical wounds, and skin abrasions. Reduces healing time by up to 9 days compared to conventional dressings.
Skin conditions (eczema, psoriasis)
Moderate evidenceClinical studies show aloe vera gel reduces symptoms of psoriasis, eczema, and seborrheic dermatitis. Anti-inflammatory compounds reduce redness, itching, and scaling.
Digestive health
Moderate evidenceAloe vera juice (decolorized, purified) reduces symptoms of IBS, GERD, and constipation. Acemannan supports gut microbiome health and reduces intestinal inflammation.
Blood sugar regulation
Some studiesSeveral clinical trials show aloe vera supplementation significantly reduces fasting blood glucose and HbA1c in type 2 diabetes patients, potentially through improved insulin sensitivity.
