What Are the Benefits of Aloe Vera?
Aloe vera, renowned for its thick, fleshy leaves and clear gel, is celebrated for its myriad health benefits. This medicinal plant, known scientifically as Aloe barbadensis, has been used for centuries for its potential therapeutic properties. Here’s a closer look at the benefits of aloe vera, along with some considerations regarding its use.
1. It Contains Healthful Plant Compounds
Aloe vera is a significant player in the cosmetic, pharmaceutical, and food industries, with an estimated annual market value of $13 billion globally. The plant’s thick, green leaves, which can grow up to 12–19 inches (30–50 centimeters) long, house a gel-like substance that is rich in bioactive compounds. This gel is packed with vitamins, minerals, amino acids, and antioxidants, making it a valuable ingredient in various health products.
2. It Has Antioxidant and Antibacterial Properties
The antioxidants in aloe vera gel, primarily polyphenols, play a crucial role in its health benefits. These polyphenols, along with other compounds in aloe, help inhibit the growth of bacteria that can lead to infections. Aloe vera is also known for its antibacterial, antiviral, and antiseptic properties, which contribute to its effectiveness in treating skin problems and supporting wound healing.
3. It Accelerates Wound Healing
Topical application of aloe vera is one of the most common uses of this plant. Historically used for treating burns and sores, aloe vera has been shown to accelerate the healing of first and second-degree burns. Research indicates that aloe vera can reduce healing time by approximately nine days compared to conventional treatments and may also alleviate redness, itching, and infections.
4. It Reduces Dental Plaque
Dental plaque and gum disease are prevalent issues that can be mitigated by reducing bacterial buildup on the teeth. Studies have shown that aloe vera mouthwash is as effective as chlorhexidine, a common mouthwash ingredient, in reducing plaque, gingivitis, and salivary Streptococcus mutans (a plaque-forming bacterium). Aloe vera gel is also effective against Candida albicans, a yeast found in the mouth.
5. It Helps Treat Canker Sores
Mouth ulcers, or canker sores, can be painful and persistent. Aloe vera treatment has been found to speed up the healing of these sores. A 2022 review of nine randomized controlled trials indicated that aloe vera is more effective than other treatments in accelerating healing and reducing pain associated with mouth ulcers.
6. It Reduces Constipation
Aloe vera latex, the yellow residue found just beneath the leaf skin, has laxative properties due to a compound called aloin. This form of aloe vera can help treat constipation. However, frequent use of aloe latex has been associated with safety concerns, and it has not been available as an over-the-counter medication in the U.S. since 2002. Aloe vera is not generally recommended for other digestive conditions like irritable bowel syndrome or inflammatory bowel disease.
7. It May Improve Skin and Prevent Wrinkles
Preliminary evidence suggests that aloe vera gel can contribute to skin health by improving collagen production and elasticity, potentially slowing skin aging. Studies have shown that oral aloe vera gel can enhance collagen levels and skin elasticity. Additionally, aloe vera may help retain skin moisture and improve integrity, benefiting dry skin conditions.
8. It Lowers Blood Sugar Levels
Aloe vera is sometimes used as a remedy for diabetes due to its potential to enhance insulin sensitivity and improve blood sugar management. A 2021 review found moderate to high-quality evidence supporting aloe vera’s effectiveness in patients with prediabetes or type 2 diabetes. However, the current quality of studies is not ideal, and aloe vera is not yet widely recommended for this purpose.
9. It Potentially Helps Hair Growth
Aloe vera has been studied for its potential benefits in treating seborrheic dermatitis, a skin condition that can cause scalp issues and hair loss. Research indicates that aloe vera may reduce itchiness and scaliness, which could indirectly support hair growth.
Important Points
- Plant Compounds: Aloe vera gel contains essential vitamins, minerals, amino acids, and antioxidants.
- Antioxidants and Antibacterial Properties: Aloe vera’s polyphenols and other compounds help inhibit bacterial growth and support overall health.
- Wound Healing: Effective in treating burns and accelerating wound healing.
- Dental Health: Reduces plaque and gingivitis, and combats oral yeast infections.
- Canker Sores: Accelerates the healing of mouth ulcers and reduces associated pain.
- Constipation Relief: Aloe latex has laxative effects, but concerns about safety limit its use.
- Skin Health: Improves collagen production and skin elasticity; beneficial for dry skin.
- Blood Sugar Management: May enhance insulin sensitivity, though further research is needed.
- Hair Growth: Potentially helps with scalp conditions and supports hair growth.
How to Use Aloe Vera
Aloe vera is available in various forms, including topical gels, ointments, and liquid extracts. It can be applied directly from the leaf or used in prepared products.
Risks
Topical use of aloe vera is generally safe, but oral consumption can cause stomach cramps or diarrhea due to its laxative properties. There are also concerns about liver injury and cancer risk associated with non-decolorized whole leaf extract. Always consult with a healthcare provider before using aloe vera for any health condition.
Summary
Aloe vera offers a range of potential health benefits, particularly for skin and dental health. While it can be used directly from the plant or in commercial products, it is important to be aware of its potential risks and consult with a healthcare professional before use.
