Cape Aloe
Also known as: Aloe ferox, Bitter Aloe, Cape Aloe Extract, Aloe ferox Miller
Effective Dosage
No established dose
What the Science Says
Cape Aloe comes from Aloe ferox, a South African plant related to common aloe vera but with a much more bitter, concentrated sap. It has been used for centuries as a natural laxative and digestive aid, and is also consumed as a health drink in parts of Europe and the US. Lab studies suggest it contains compounds with anti-inflammatory properties and may inhibit certain tumor cell growth in test tubes, but these findings have not been confirmed in human clinical trials.
What It Doesn't Do
No proven cancer-fighting effect in humans — the tumor research is early-stage lab work only. Not a substitute for medical laxatives when prescribed. No solid evidence it detoxifies the liver, boosts immunity, or fights infections in humans. Don't expect dramatic health benefits beyond digestive support.

Absorption & Bioavailability
Unknown — no human pharmacokinetic studies found in the provided data. Active compounds like aloeresin and aloesin are identified, but absorption rates in humans are not established.
Red Flags to Watch For
- Stimulant laxatives like those in Cape Aloe can cause dependency with long-term use — your bowels may stop working normally without it
- Can cause severe cramping, diarrhea, and electrolyte imbalances, especially at high doses
- Not safe during pregnancy — stimulant laxatives are associated with uterine contractions
- Very little human clinical trial data exists; most evidence is traditional use or animal/cell studies
- Widely sold in supplements despite minimal regulatory oversight of dosing or purity standards
