Nine Health Benefits and Medical Uses of Aloe Vera
Aloe vera, a thick-stemmed plant with water-storing leaves, has been used for centuries due to its wide range of therapeutic benefits. This article explores nine potential health benefits of aloe vera, including its applications for skin care, digestive health, and more, while also addressing some of the risks associated with its use.
What is Aloe Vera?
Aloe vera, scientifically known as Aloe barbadensis, is recognized for its thick, fleshy leaves that contain a gel-like substance. This gel is packed with beneficial bioactive compounds, including vitamins, minerals, amino acids, and antioxidants, which contribute to its medicinal properties. Aloe vera is cultivated worldwide and used in various industries, from cosmetics to pharmaceuticals, with an estimated global market value of $13 billion.
Nine Scientifically Backed Benefits of Aloe Vera
Aloe vera is celebrated for its numerous medicinal claims. While some are not rigorously supported, several benefits are validated by research. This article highlights nine such benefits.
1. Teeth and Gums
- Study Source: General Dentistry
- Findings: Aloe vera tooth gel was found to be as effective as, and sometimes superior to, commercial toothpastes in fighting cavities.
- Mechanism: Aloe latex contains anthraquinones that provide natural anti-inflammatory effects and pain relief.
- Caveat: Only gels with stabilized Aloe vera, from the plant’s center, are effective.
2. Constipation
- Regulatory Approval: Commission E (Germany)
- Dosage: 50-200 milligrams of Aloe latex, taken daily in liquid or capsule form for up to 10 days.
- U.S. Status: The FDA has not approved Aloe vera for constipation treatment due to insufficient data on safety and efficacy.
3. Diabetes-Induced Foot Ulcers
- Study Source: Sinhgad College of Pharmacy, India, published in International Wound Journal
- Findings: Aloe vera gel significantly promoted wound healing and closure in diabetic rats compared to commercial products.
- Potential Use: Shows promise as a treatment for diabetes-induced foot ulcers.
4. Antioxidant and Antimicrobial Properties
- Study Source: University of Las Palmas de Gran Canaria, Spain, published in Molecules
- Findings: Aloe vera leaf skin and flower extracts have antioxidant properties. Leaf skin extract also exhibits antimicrobial activity against mycoplasma, bacteria resistant to many antibiotics.
- Conclusion: Aloe vera extracts are effective natural antioxidant sources.
5. Protection from Ultraviolet (UV) Irradiation
- Study Source: Kyung Hee University Global Campus, South Korea, published in Phytotherapy Research
- Findings: Baby Aloe shoot extract (from 1-month-old shoots) may better protect the skin from UVB-induced damage compared to adult Aloe shoot extract (from 4-month-old shoots).
- Potential Benefit: Could help in preventing UV-induced skin aging.
6. Protection from Skin Damage After Radiation Therapy
- Study Source: University of Naples, Italy, published in Radiation Oncology
- Findings: Various topical creams, including those with Aloe, reduced skin side effects from radiation therapy. No cream significantly outperformed others.
- Conclusion: All creams, including Aloe, were equally valid for preventing radiation-induced skin damage.
7. Depression, Learning, and Memory – Animal Study
- Study Source: Published in Nutritional Neuroscience
- Findings: Aloe vera improved learning and memory while alleviating depression in mice.
- Further Research: More studies are needed to determine if these benefits extend to humans.
8. Wounds from Second-Degree Burns
- Study Source: Journal of Pakistan Medical Association
- Findings: Aloe vera gel healed second-degree burn wounds faster and provided earlier pain relief compared to 1% silver sulfadiazine cream.
- Conclusion: Aloe vera showed advantages in wound epithelialization, pain relief, and cost-effectiveness.
9. Irritable Bowel Syndrome (IBS)
Conclusion: Further research is needed to explore Aloe vera’s potential benefits in less complex IBS cases.
Study Source: St. George’s Hospital Medical School, London, published in International Journal of Clinical Practice
Findings: Aloe vera did not show significant benefits for IBS symptoms compared to a placebo. However, improvements in specific IBS subtypes could not be ruled out.
How to Use Aloe Vera
Aloe vera can be utilized in various forms, including topical gels, ointments, or as a raw leaf extract. It is also available in liquid form for consumption. For topical use, apply aloe vera gel directly to the skin. For internal use, ensure products are decolorized to minimize risks.
Risks of Aloe Vera
While aloe vera is generally considered safe for topical use, there are some risks associated with its oral consumption. Potential side effects include stomach cramps and diarrhea. Non-decolorized whole leaf extracts may carry cancer risks, and it’s advisable to consult a healthcare provider before using aloe vera for any health condition.
Summary
Aloe vera offers a range of therapeutic benefits, particularly for skin care and oral health. Its applications extend to managing blood sugar levels and potentially promoting hair growth. However, users should be cautious with oral aloe vera and consult healthcare professionals before starting any new treatment regimen.
