Although the gel of the plant is famous for its ability to take the sting and heat out of a sunburn, the beneficial properties of aloe vera, Aloe barbadensis, reach much further than skin deep. Ancient peoples have used this soothing plant for a wide range of applications, from controlling irritation to keeping wounds clean, and soothing gastrointestinal upset. New research reveals that aloe vera’s healing capabilities may be more numerous than previously believed. It has a wealth of health-promoting compounds to offer nearly all of the body’s systems.
What Nutrients Does Aloe Vera Contain?
Though you might not think of it for its nutritional qualities, aloe vera is an all-star superfood. It contains a broad spectrum of essential nutrients and beneficial plant compounds. At this point, about 75 different nutrients have been identified.
Vitamins In Aloe Vera
- Vitamin A (beta-carotene): A fat-soluble vitamin that supports the immune system, vision, reproductive health and the chemical communication between your cells
- Vitamin C: An antioxidant involved in healthy immune function, collagen synthesis, and wound repair
- Vitamin E: A fat-soluble antioxidant that helps regulate gene expression and may inhibit the development of cardiovascular disease
- Vitamin B12: A B vitamin involved in healthy cognitive function, brain aging, the synthesis of DNA, and the production of red blood cells
- Folate: Another B vitamin that contributes to the conversion of amino acids and the formation of DNA
Minerals In Aloe Vera
- Calcium: A macromineral involved in bone strength, the contraction of muscles, and metabolic functions
- Chromium: A trace mineral responsible for blood sugar balance and immune functions
- Copper: A cofactor involved in the release of energy, the development of certain tissues, and the transmission of nerve impulses
- Selenium: A trace mineral that contributes to immune defenses, such as the regulation of cell growth and cell death
- Magnesium: A cofactor involved in the function of hundreds of enzymes including those involved in glucose metabolism, protein synthesis, calcium balance, and blood sugar regulation
- Manganese: An essential part of an important antioxidant enzyme produced by the body — manganese superoxide dismutase
- Potassium: A critical mineral and electrolyte concerned with nerve impulses, muscle, and heart contractions
- Sodium: Another electrolyte involved in muscle function and nerve impulses[15, 16]
- Zinc: A trace mineral involved in growth, development, reproduction, brain function, and metabolism
Phytonutrients In Aloe Vera
Though these aren’t necessary according to government guidelines, an overwhelming proportion of evidence suggests that many of these plant compounds support excellent health. Aloe vera contains many phytonutrients that are involved in immune responses to damaged tissue, both on the surface and internally. Some of these phytonutrients include:
Enzymes In Aloe Vera
Aloe vera contains at least eight different types of enzymes — alliinase, alkaline phosphatase, amylase, bradykinase, carboxypeptidase, catalase, cellulase, lipase, and peroxidase. Bradykinase can help reduce skin swelling and irritation when applied to the skin. Some of the other enzymes can help the body break down nutrients in the digestive tract and even prompt the recycling of damaged tissue in the body itself.
Health Benefits of Aloe Vera
There are extensive benefits that stem from regularly using and even eating aloe. These effects extend from the skin inward to your circulatory system. From here they can travel through the body promoting good health.
Part of a Healthy, Anti-aging Diet
As you saw earlier, aloe vera is brimming with micronutrients like antioxidants, which help slow the aging process at the cellular level. But that’s just the tip of the aloe iceberg. One study on women aged 45 years or older found that eating aloe itself improves skin elasticity, boosts collagen production, and significantly reduces wrinkles. Though the study was small, it found that sun-damaged skin and sun-protected skin both improved in appearance.
Balances Blood Composition for Cardiovascular Health
Some studies have shown that aloe vera supports normal blood sugar. Researchers reported that 5 active compounds in aloe vera reduced fasting blood sugar levels in mice up to 64% when consumed for four weeks. The same mice showed a 15% decrease in the A1C blood sugar levels. This is significant because high blood sugar increases the presence of free radicals in the blood. It also increases damage to LDL cholesterol, which can lead to arterial plaques and the development of heart disease.
Stimulates the Immune System
Acemannan, one of the active compounds in aloe vera, provokes the production of proteins that boost your body’s defense against foreign or old, malfunctioning cells. It also encourages greater specialization in your dendritic cells, which are the immune cells that call the police — other immune cells — when they see suspicious activity in their neighborhood.
In an animal study, researchers discovered that eating aloe vera helps the body naturally boost red and white blood cell counts after aggressive medical treatments that suppress them.
Encourages Wound Repair
Aloe vera powder and gel is a common addition to natural skin products and cosmetics because it nourishes, moisturizes, and protects skin. Knowledge of these skin benefits has been widely applied for centuries, dating as a far back as ancient Indian, Roman, Greek, Iberian, and Arab folk medicine. Today, aloe is still used for relatively minor skin complaints, like an uncomfortable sunburn, but it can also soothe scratches, scrapes, burns, rashes, and other skin wounds.
Multiple studies have confirmed that it supports the healing of skin wounds and stimulates cellular rejuvenation. The gel of the aloe plant contains a few different plant compounds that help promote normal skin health. Aloe enzymes support the production of collagen and help your body break down damaged tissue in wounds, while glycoproteins in the gel set the stage for new skin cells to proliferate.[19, 31] Additional research has found that it decreases healing time and for first- and second-degree burns. In human studies, aloe vera gel was found to improve skin integrity in dry, cracked skin and reduce irritation, wrinkling, and irritation from injuries.
Supports Oral Health
Aloe gel also promotes gum and dental health. It soothes swollen gums and protects them from irritating germs. One study found that swishing aloe gel in your mouth is just as effective at cleaning your mouth — if not more so — than commercial mouthwashes.[2, 33]
Promotes Digestive Comfort and Gut Health
Another study indicates that aloe vera can help your stomach naturally cleanse itself of harmful organisms to promote greater comfort. It also helps the cells in your stomach lining increase mucosal production to insulate them from gastric acid. Because of this protective effect, aloe is included in some ulcer medications.
But aloe isn’t just for stomach health, it also promotes gut health. The acemannan in aloe is a complex sugar that you can’t digest, much like fiber, but your microbiota thrives on it. Nurturing the friendly bacteria in your gut with prebiotics like acemannan not only helps preserve your gastrointestinal health, it lays the groundwork for your overall health and well-being.[30, 36]
Protects You From Oxidative Stress
Aloe gel itself contains several antioxidants, like vitamins C and E, selenium, and a few phytonutrients that actively scavenge the free radicals that cause oxidative damage and accelerate the aging process.[19, 37]
Remarkably, the gel also helps your body produce antioxidants. One of your most powerful antioxidant scavengers is produced by the body, like superoxide dismutase (SOD) and glutathione, which neutralizes superoxides. Consuming aloe gel helps your body increase production of these cunning chemical allies that protect you from oxidative damage.
Inhibits Growth of Harmful Organisms
Your hygiene and the foods you eat are strong determinants of how your body interacts with your microbiota — and how it affects your health in turn. The prebiotic potential of acemannan reinforces your natural defenses against harmful, opportunistic organisms that can compromise your health when your immune system is depressed, otherwise occupied, or when it's busy repairing other injuries.
Fortunately, aloe not only encourages the growth and health of beneficial probiotic colonies, but it also suppresses the same in colonies of harmful organisms in the skin, injuries, stomach, and the lining of the gut.[19, 34, 38]
The Best Forms of Aloe Vera and How to Get More In Your Diet
