Question 1

How does Bitter Aloe work as a laxative?

Accepted Answer

Aloe ferox contains anthraquinone glycosides, primarily aloin and aloe-emodin, which act as stimulant laxatives. These compounds pass through the small intestine unabsorbed and are metabolized by colonic bacteria into active metabolites. These metabolites stimulate the myenteric plexus, increasing intestinal motility, and promote fluid secretion into the colon. This dual action produces a bowel movement within 6-12 hours after ingestion. Evidence Level: C, based on pharmacological studies and traditional use.

Question 2

Can I take Bitter Aloe with other medications?

Accepted Answer

Aloe ferox has significant drug interactions due to its strong laxative effects and potential for electrolyte depletion. It should not be combined with cardiac glycosides such as digoxin, as hypokalemia increases cardiac toxicity risk. Concurrent use with diuretics, corticosteroids, or other stimulant laxatives compounds electrolyte disturbances. Long-term use may reduce absorption of medications due to increased gut motility. Patients on antiarrhythmics or anticoagulants should consult a healthcare provider before use. Evidence Level: C.

Question 3

What is the correct dosage of Bitter Aloe for constipation?

Accepted Answer

The standard adult dosage for Aloe ferox as a laxative is 10-30 mg of aloin equivalent, taken once daily at bedtime. This typically produces a bowel movement the following morning. Treatment duration should not exceed 7-10 consecutive days without medical supervision, as longer use risks dependence and electrolyte imbalance. The lowest effective dose should be used initially. Topical gel application for skin conditions can be applied as needed. Evidence Level: C, based on traditional use and pharmacopoeial standards.

Question 4

Is Bitter Aloe safe during pregnancy and breastfeeding?

Accepted Answer

No, Aloe ferox is contraindicated during pregnancy and breastfeeding. The anthraquinone compounds stimulate uterine contractions and may cause miscarriage or premature labor. These compounds also pass into breast milk, potentially causing diarrhea and electrolyte disturbances in nursing infants. Pregnant women should avoid all oral preparations containing Cape aloe. Topical gel application may be considered for minor skin conditions but should be discussed with a qualified healthcare provider first. Evidence Level: C.

Question 5

What are the side effects of taking Bitter Aloe?

Accepted Answer

Common side effects include abdominal cramping and urgent bowel movements due to the strong stimulant action. More serious effects include electrolyte depletion, particularly hypokalemia, with prolonged use. Chronic use may cause hepatotoxicity, kidney damage, and laxative dependence, where the colon loses normal function. People with inflammatory bowel disease, kidney disease, or children under 12 should avoid oral use entirely. Discontinue use if severe cramping, dehydration symptoms, or persistent diarrhea occurs. Evidence Level: C.

Question 6

What is Bitter Aloe used for traditionally?

Accepted Answer

Aloe ferox has been used for centuries by the Khoikhoi and other Southern African peoples. The bitter leaf juice is one of the strongest natural laxatives, traditionally used for constipation relief. The inner leaf gel is applied topically for wound healing, burns, and various skin conditions. Modern applications continue these traditional uses, with Cape aloe juice primarily employed as a stimulant laxative and the gel used in skin preparations. Evidence Level: C, based on traditional use.
