Grinjana
Grinjana is a substance used in the Ayurvedic materia medica. Beta-carotene bioavailability is highly dependent on food matrix and fat content: raw carrot (~3% absorption) vs cooked with oil (~30-40%). Carotenoids are fat-soluble - co-administration with lipids (ghee, oil) dramatically enhances absorption.

What is it made of?
Mineral/Elemental Profile
- Primary component: Mineral-derived preparation
- Note: Composition varies by specific preparation method
Analytical Methods: XRD, ICP-OES, SEM-EDS
Dosage forms and preparation
Dosage Forms: Fresh root (culinary/medicinal), Churna (dried root powder), Swarasa (fresh juice), Tablet, Capsule, Avaleha
Standard Dosage: Fresh root: 50-100g daily in diet; Dried powder: 3-6g twice daily; 50-100ml fresh juice; 500mg extract capsule twice daily
Bioavailability: Daucus carota (carrot / Grinjana) root contains carotenoids (beta-carotene, alpha-carotene, lutein), polyacetylenes (falcarinol, falcarindiol), and anthocyanins (in purple varieties). Beta-carotene bioavailability is highly dependent on food matrix and fat content: raw carrot (~3% absorption) vs cooked with oil (~30-40%). Carotenoids are fat-soluble - co-administration with lipids (ghee, oil) dramatically enhances absorption. Traditional Ayurvedic practice of cooking carrots with ghee aligns with modern bioavailability science. Polyacetylenes have moderate oral bioavailability. Enhancement: cooking and pureeing disrupts cell walls releasing carotenoids; oil-based formulations; nano-emulsions.
Optimal Timing: With meals containing fat/oil for maximum carotenoid absorption; fresh juice in the morning; Avaleha after meals as nutritive tonic
Standardized Extract: Carrot extract standardized to NLT 10% total carotenoids (as beta-carotene) by HPLC. Cold-pressed carrot seed oil: rich in carotol and daucol. Freeze-dried carrot powder: beta-carotene NLT 200 ppm.
Shelf Life: Fresh root: 2-4 weeks refrigerated; Dried powder: 1.5 years (protect from light - carotenoid degradation); Capsule: 2 years; Juice: 7 days refrigerated, 6 months pasteurized sealed
Storage: Fresh: refrigerate at 2-8 deg C. Dried powder and extracts: airtight, opaque containers below 25 deg C - carotenoids degrade rapidly on light exposure. Nitrogen-flush packaging recommended. Seed oil: refrigerate after opening.
Marker Compounds: Beta-carotene, Alpha-carotene, Lutein, Falcarinol, Falcarindiol, Carotol (seed oil), Anthocyanins (purple carrot varieties)
Extraction Methods
- Fresh juice expression (Swarasa)
- Hot water extraction for Kashayam
- Supercritical CO2 for carotenoid-rich extract
- Oil-based extraction for fat-soluble carotenoids
- Freeze-drying for preservation of labile nutrients
- Ethanol extraction for polyacetylene fraction
Synergistic Combinations
- With Ghrita (ghee) for maximum carotenoid absorption
- With Amalaki for antioxidant synergy (vitamin A + C)
- With Shatavari for nutritive and Rasayana combination
- With Yashtimadhu for eye health formulation
Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.
