Medicinal Benefits of Aloe Vera

1. Skin Health and Wound Healing

Aloe vera gel is widely recognized for its efficacy in treating burns, wounds, and skin irritations. Clinical studies have demonstrated that Aloe vera accelerates wound healing by enhancing collagen synthesis and reducing inflammation. A systematic review published in the Journal of Burn Care & Research concluded that Aloe vera significantly improves healing times for first- and second-degree burns Wikipédia.

2. Anti-Inflammatory and Antioxidant Properties

The plant’s anti-inflammatory effects are attributed to compounds like C-glucosyl chromone, which inhibit cyclooxygenase pathways, and anthraquinones, which reduce prostaglandin E2 production. Additionally, Aloe vera’s antioxidant properties help neutralize free radicals, mitigating oxidative stress and associated cellular damage PMC.

3. Digestive Health and Laxative Effects

Aloe vera latex contains anthraquinones, potent natural laxatives that stimulate peristalsis and increase intestinal water content. While effective for short-term constipation relief, prolonged use is not recommended due to potential adverse effects. Aloe vera gel, on the other hand, has been shown to soothe the digestive tract, alleviate symptoms of irritable bowel syndrome (IBS), and promote gut health WebMD.
