Aloe Vera: Uses, Benefits, Dosage & Safety
Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Aloe vera gel is well known for soothing burns and skin irritation topically. Taken orally it's used for digestion, but oral aloe latex (not the gel) is a harsh laxative with real safety concerns.
What is Aloe Vera?
Aloe vera is a succulent plant with two very different parts: the clear inner gel (used topically and in some drinks) and the yellow latex just under the skin (a strong laxative). Topical gel is used for burns, wounds and skin; oral aloe is marketed for digestion and 'detox'.
What Aloe Vera is commonly used for
In supplements, Aloe Vera is most often included for gut & digestive health, skin & anti-aging support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Aloe Vera works
Topically, aloe gel has soothing, moisturising and mild anti-inflammatory effects that aid minor burns and skin irritation. Orally, the gel's polysaccharides are proposed to support digestion, while the latex's anthraquinones act as a stimulant laxative.
What the evidence says
Here's an honest snapshot of what published research suggests about Aloe Vera — including where the evidence is limited.
- Topical aloe gel has reasonable evidence for soothing minor burns, sunburn and some skin conditions. (PubMed research)
- Oral aloe gel has limited evidence for digestive benefit; oral aloe latex works as a laxative but carries safety concerns. (PubMed research)
Typical dosage used in studies
Topical gel is applied as needed; oral products vary, and decolourised, latex-free aloe is preferred for any oral use. This is research information for context, not a recommendation — confirm what's appropriate for you with a healthcare professional.
Side effects and safety
Topical aloe is very safe. Oral aloe latex can cause cramping, diarrhoea and electrolyte loss, and long-term use of aloe latex has been linked to potential health risks.
Medication interactions and who should avoid Aloe Vera
Medication & safety check
Oral aloe latex (laxative) can deplete potassium and interact with heart, diuretic and diabetes medication. Avoid oral aloe latex in pregnancy and bowel conditions.
This is general information, not personal medical advice. If you take any medication, confirm it's safe to combine with Aloe Vera with your doctor or pharmacist first.
