Bilva Majja

Names and identification

Language	Name
English	Bilva Majja
Latin/Botanical	Aegle marmelos (L.) Correa (fruit pulp)

Key Phytochemical Constituents

• Marmelide
• Marmelosin
• Psoralen
• Imperatorin
• Aegeline
• Marmin
• Beta-carotene
• Mucilage
• Pectin
• Vitamin C

How does it work?

• Marmelosin and marmelide (furocoumarins) inhibit prostaglandin synthesis and exhibit antidiarrhoeal activity by reducing intestinal motility and enhancing water absorption in the gut
• Psoralen and imperatorin exert antidiabetic effects by enhancing insulin secretion from pancreatic beta cells and improving peripheral glucose uptake through GLUT4 transporter upregulation
• Pectin and mucilage in fruit pulp form a protective barrier on gastric mucosa, exhibiting gastroprotective activity against acid-induced ulceration

Which traditional uses are supported by research?

• Antidiarrhoeal activity extensively validated through multiple pharmacological studies confirming traditional Ayurvedic use of Bilva Majja for Atisara (diarrhea) and Grahani (IBS)
• Antidiabetic effects validated through coumarins-enriched extract studies supporting traditional use for Prameha (diabetes) in classical Ayurvedic texts
• Radioprotective activity validated in preclinical models, a novel finding extending beyond traditional uses

What do recent clinical trials show?

Correa fruit pulp, as an anti-diabetic and anti-inflammatory agent. Saudi pharmaceutical journal : SPJ : the official publication of the Saudi Pharmaceutical Society. PMID 37564748 · doi:10.1016/j.jsps.2023.101708
  Coumarins enriched from bael fruit pulp demonstrated significant anti-diabetic and anti-inflammatory activity, validating potential for phytopharmaceutical development.

Recent safety updates

• Fruit pulp is widely consumed as food and traditional medicine with long history of safe use; ethanolic leaf extract showed minimal cytotoxicity at low concentrations (6.3 ul/ml)
• No significant systemic toxicity reported at therapeutic doses; variability in phytochemical composition between specimens may affect dosing consistency
• Insufficient clinical trials exist to fully validate safety; standardized formulations are needed for reliable therapeutic application

Dosage forms and preparation

Dosage Forms: Avaleha (confection/jam), Churna (pulp powder), Kashayam (decoction), Capsule, Tablet

Standard Dosage: 5-10g pulp (fresh or dried) twice daily; 3-6g dried pulp powder; 50-100ml decoction; as Bilva Avaleha 10-20g

Bioavailability: Bilva Majja (fruit pulp/marrow) contains high mucilage and pectin which form a protective gel in the GI tract—this is the therapeutic mechanism for antidiarrheal action rather than systemic absorption. Coumarins present in the pulp show moderate oral bioavailability. Carotenoids in ripe pulp benefit from lipid co-administration.

Optimal Timing: Before meals for diarrhea management; after meals as digestive tonic; Avaleha can be taken anytime

Standardized Extract: Dried pulp powder standardized to total mucilage NLT 15%; tannin content NLT 5% (unripe); marmelosin NLT 0.5%

Shelf Life: 18 months (dried pulp powder); 2 years (Avaleha); 3 years (capsule/tablet)

Storage: Dried pulp powder in airtight containers with desiccant—highly hygroscopic. Avaleha in glass jars away from moisture. Temperature below 25°C.

Marker Compounds: Marmelosin, Marmelide, Pectin, Mucilage polysaccharides, Beta-carotene (ripe fruit), Tannins (unripe fruit), Riboflavin

Extraction Methods

• Mechanical separation of pulp from shell and seeds
• Aqueous extraction for mucilage-rich fraction
• Hydroalcoholic extraction (50:50) for coumarin enrichment
• Sun-drying or tray-drying of pulp for powder preparation
• Traditional Avaleha preparation with sugar and spices

Synergistic Combinations

• With Sunthi and Jaggery in traditional Bilva Avaleha
• With Kutaja for enhanced antidiarrheal effect
• With Dadima rasa for malabsorption
• With Musta and Ativisha for pediatric diarrhea formulations
