Also known as: Aloe ferox, Bitter Aloe, Cape Aloe, Aloe ferox Mill.
Effective Dosage
No established dose
What the Science Says
Cape Aloe is a succulent plant native to South Africa, distinct from the common Aloe vera. It contains bitter compounds called anthraquinones — primarily aloin — which have a long history of traditional use as a stimulant laxative for occasional constipation. These compounds work by irritating the colon lining to stimulate bowel movements, typically within 6–12 hours of ingestion. Despite its widespread use in supplements, no clinical trials were identified in the available research to confirm its effectiveness or establish a safe dose.
What It Doesn't Do
Not a gentle or everyday digestive aid — it's a harsh stimulant laxative. No evidence it detoxifies the body. Won't help with weight loss despite appearing in 'cleanse' products. Not a substitute for fiber or a healthy diet. No proven benefit for skin, immunity, or inflammation based on available data.

Absorption & Bioavailability
Unknown — no pharmacokinetic data available from provided studies. Anthraquinone compounds are known to be metabolized by gut bacteria before absorption, but clinical data on Cape Aloe specifically is lacking.
Red Flags to Watch For
- Long-term use of anthraquinone laxatives is associated with a condition called melanosis coli (darkening of the colon lining) and may worsen chronic constipation
- Aloin, the active compound, was removed from over-the-counter laxative products in the US by the FDA in 2002 due to insufficient safety data — products containing it are not FDA-approved laxatives
- Frequently found in 'detox' and 'cleanse' products with exaggerated marketing claims not supported by clinical evidence
- May interact with medications including diuretics, heart medications, and corticosteroids due to potential electrolyte imbalances from laxative effect
- Not safe during pregnancy, breastfeeding, or for children — traditional use warnings are well-established even without modern clinical trials
