Aloe Vera
Also known as: Aloe barbadensis miller, aloe gel, aloe latex, acemannan
Effective Dosage
No established dose from provided studies
What the Science Says
Aloe vera is a succulent plant whose gel and extracts have been used medicinally for centuries. Based on the provided studies, it shows the most promise as a topical agent — small clinical trials suggest it may reduce gum inflammation when used as a massage gel, help manage dry eye symptoms when formulated into artificial tears, and support skin barrier protection in incontinence-related dermatitis. One pilot trial found an aloe-based nitroglycerin gel delivered sustained angina relief, though aloe was acting as a delivery vehicle rather than the active drug.
What It Doesn't Do
Not proven to detox your body. No human evidence from these studies that it burns fat or boosts metabolism. Don't assume 'natural' means safe for your eyes — putting unsterile aloe directly in your eyes can cause serious infections and corneal damage. The animal and lab studies here don't translate to proven human benefits. No evidence it treats cancer, diabetes, or serious internal conditions based on the provided papers.
Evidence-Based Benefits
May have mild laxative effect. Traditional use for digestive soothing. Topical use well-supported for skin.
Weak EvidenceEffective at: 50-200ml juice or gel daily

Absorption & Bioavailability
Unknown for oral use based on provided studies. Topical formulations show local activity at application sites. Transdermal delivery (as a gel vehicle) demonstrated sustained drug release in one pilot trial.
Red Flags to Watch For
- Applying aloe directly to eyes (non-sterile) is linked to serious corneal infections and potential blindness — documented in traditional medicine harm reduction literature
- Most provided studies are small pilots (n=20–150) with short follow-up; results cannot be generalized
- Several papers use aloe as a delivery vehicle or excipient, not as the active therapeutic ingredient — marketing may overstate its role
- Animal and lab (in vitro) studies dominate the mechanistic claims; these do not confirm human benefits
- No standardized dosing exists across studies, making it impossible to know what amount in a supplement is effective or safe
