Psyllium husk is an official pharmacopoeial ingredient with monographs in the United States Pharmacopeia (USP), British Pharmacopoeia (BP), and European Pharmacopoeia (Ph. Eur.). Pharmaceutical manufacturers require psyllium that meets these specifications — not just food-grade quality standards.
What Does "Pharma Grade" Mean for Psyllium Husk?
Pharma grade psyllium husk meets specifications set by recognized pharmacopoeias and is manufactured under GMP (Good Manufacturing Practice) conditions. It requires stricter quality controls, lower microbial limits, tighter assay specifications, and GMP facility documentation compared to food-grade product.
USP Monograph (United States Pharmacopeia)
The USP Psyllium Husk monograph specifies: - Identification test confirming Plantago ovata origin - Swelling power: Not less than 9 mL/g for powder; not less than 40 mL/g for whole husk (per USP method) - Acid insoluble ash: Not more than 1.0% - Total ash: Not more than 4.0% - Microbial limits: Stricter than food grade — total aerobic count ≤ 10,000 CFU/g; E. coli absent in 10g; Salmonella absent in 25g - Heavy metals: Per USP <231> or <2232> limits
BP Monograph (British Pharmacopoeia)
The BP uses the name "Ispaghula Husk" (the official BP name for psyllium husk). Key specifications: - Swelling index: Not less than 40 mL/g - Foreign matter: Not more than 3.0% - Total ash: Not more than 5.0% - Complete microbial testing per BP 2.6.12
European Pharmacopoeia (Ph. Eur.) — "Ispaghula Husk"
The Ph. Eur. monograph 0858 for Ispaghula Husk is used by European pharmaceutical manufacturers including in Germany, France, Italy, Spain, Netherlands, and all EU member states. Key requirement: Swelling index ≥ 40.
What Documentation Do Pharma Buyers Need?
For pharma applications, suppliers must provide: (1) Batch-specific COA showing pharmacopoeial compliance with all test results (2) GMP certificate or ISO 22000 certification (3) Reference to specific pharmacopoeia tested against (4) Microbial testing per pharmacopoeial limits (5) Heavy metals per pharmacopoeial specifications (6) Residual solvents declaration (if applicable) (7) TSE/BSE statement (confirming no animal-derived materials)

Frequently Asked Questions
What is the difference between pharmaceutical grade and food grade psyllium husk?
Pharmaceutical grade psyllium husk must meet pharmacopoeial specifications (USP, BP, or Ph. Eur.) with stricter purity limits, documented test methods, and tighter heavy metals and microbial controls. Food grade psyllium meets FSSAI or food safety standards which are less stringent. Pharma grade requires a full COA citing specific pharmacopoeial test methods and comes with additional regulatory documentation like TSE/BSE declarations.
Does psyllium husk meet USP and European Pharmacopoeia standards?
Yes. Psyllium husk is officially monographed in USP (Psyllium Husk, USP), British Pharmacopoeia (Ispaghula Husk, BP), and European Pharmacopoeia (Ispaghula Husk, Ph. Eur.). Each pharmacopoeia specifies swelling index, loss on drying, ash content, and microbial limits. Amar Herbal Origins supplies psyllium husk with COA parameters tested against all three pharmacopoeial standards.
Is psyllium husk Halal and Kosher certified?
Yes. Psyllium husk (Isabgol) is naturally plant-derived and is Halal and Kosher by nature. Amar Herbal Origins holds formal Halal certification (FSSAI-recognized Halal certifying body) and Kosher certification. Certificates are provided with every shipment and are available for regulatory submissions.
What is the swelling factor/index required for pharmaceutical grade psyllium husk?
The USP specifies a swelling volume of not less than 40 mL/g for psyllium husk. The European Pharmacopoeia (Ph. Eur.) specifies a swelling index of not less than 9 for ispaghula husk. Our 99% purity psyllium husk consistently achieves swelling volumes of 42–48 mL/g (whole husk) and 52–58 mL/g (powder), exceeding both USP and Ph. Eur. minimums.
Amar Herbal Origins processes premium 99% purity whole husk and fine powders. We hold ISO 22000, USDA/EU Organic, Kosher, and Halal certifications.
