Aloe ferox contains aloin, a potent anthraquinone that stimulates colon contractions and promotes bowel movements. This Cape aloe species provides stronger laxative effects than common aloe vera while supporting wound healing through anti-inflammatory compounds.
Reported Benefits (Provisional)
Origin & History
Aloe ferox, also known as Cape Aloe, is a succulent plant native to South Africa. It is harvested for its gel and latex, which are used in various medicinal and cosmetic products.
Research Narrative (Provisional)
Research on Aloe ferox includes studies on its laxative effects and potential benefits for skin health. Some clinical trials have shown its effectiveness in treating constipation and improving skin hydration.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Aloe ferox (Cape Aloe) contains a complex array of bioactive compounds with limited standardized nutritional data, but key constituents are well-documented. Primary bioactive compounds include anthraquinones (aloin A and B, collectively 'barbaloin') at concentrations of 6–35% dry weight in the bitter sap/latex — significantly higher than Aloe vera (typically 0.1–2%). The gel fraction contains polysaccharides, primarily acemannan and other beta-glucomannans, estimated at 0.2–0.5% of fresh gel weight, which are responsible for immunomodulatory and wound-healing activity. Phenolic compounds include aloe-emodin, chrysophanol, and emodin at trace levels (1–5 mg/g dry latex). Minerals present in the gel include calcium (~9 mg/100g), magnesium (~8 mg/100g), potassium (~160 mg/100g), sodium (~8 mg/100g), and trace zinc and iron. Vitamins identified include vitamin C (~5–10 mg/100g fresh gel), vitamin E (alpha-tocopherol, ~0.1 mg/100g), and small amounts of B vitamins including B1, B2, B6, and folate at sub-milligram levels. Amino acids are present including glutamic acid, aspartic acid, and glycine, with total protein content approximately 0.1–0.5% of fresh gel weight — low bioavailability. Fiber content in gel is minimal (~0.3–0.5% fresh weight), while the whole leaf contains more structural cellulose. Bioavailability note: Anthraquinosides (aloin) are poorly absorbed in the small intestine and reach the colon intact where they exert laxative effects via bacterial metabolism; acemannan polysaccharides have moderate bioavailability and are partially absorbed via endocytosis in gut epithelial cells.
Reported Mechanism (Provisional)
Aloin and other anthraquinones in Aloe ferox are metabolized by gut bacteria into rhein-anthrone, which irritates the colon lining and stimulates peristaltic contractions. The plant's polysaccharides and glycoproteins activate wound healing pathways by promoting fibroblast proliferation and collagen synthesis. Anti-inflammatory effects occur through inhibition of cyclooxygenase and lipoxygenase enzymes.
Clinical Narrative (Provisional)
Small clinical trials show Aloe ferox extract reduces constipation symptoms within 8-12 hours in 80-90% of participants. Topical studies demonstrate 50% faster wound healing compared to placebo in groups of 30-60 subjects. Most research consists of preliminary studies rather than large-scale randomized controlled trials. Evidence supports traditional laxative uses but long-term safety data remains limited.
