An Ayurvedic fruit traditionally used for diarrhoea and dysentery. The pharmacology is documented in animals and cell culture; controlled human trials are absent.
Evidence last reviewed: August 2026
What the science says
- Antidiarrhoeal activity in preclinical models Limited evidence
Pharmacological reviews of Aegle marmelos describe antidiarrhoeal, antimicrobial and mucosa-protective effects in rodent and in-vitro models, attributed to tannins and coumarins such as marmelosin.
- No controlled human trials Limited evidence
Recent reviews integrating traditional knowledge with modern physiology note that randomized clinical trials of bael are missing; the human evidence remains traditional use rather than experiment.
Dosage & safety
Studied doseTraditional preparations use 2–5 g/day of dried unripe fruit powder. No dose has been established in a clinical trial.
SafetyFew reports of harm at food-like doses, but long-term safety is unstudied. Animal work points to possible effects on fertility and blood glucose, so avoid in pregnancy and use caution alongside diabetes medication. Acute diarrhoea with fever or blood needs medical care, not a fruit powder.
