Draksha
Vitis vinifera
Draksha (Vitis vinifera) is a plant used in Ayurveda. Resveratrol has low oral bioavailability (<1% as free resveratrol) due to rapid glucuronidation and sulfation. However, resveratrol metabolites (resveratrol-3-O-glucuronide, resveratrol-3-sulfate) retain partial biological activity.

Dosage forms and preparation
Dosage Forms: Swarasa (juice), Churna (dried fruit powder), Avaleha (confection/jam), Kashayam (decoction), Mridvika preparation, Capsule, Tablet
Standard Dosage: 10-20g dried grapes (Munakka) soaked and consumed; 50-100ml fresh juice; 5-10g powder twice daily; 1-2 teaspoons Avaleha twice daily
Bioavailability: Vitis vinifera (grape/raisin) contains polyphenols including resveratrol, proanthocyanidins (OPCs), and anthocyanins. Resveratrol has low oral bioavailability (<1% as free resveratrol) due to rapid glucuronidation and sulfation. However, resveratrol metabolites (resveratrol-3-O-glucuronide, resveratrol-3-sulfate) retain partial biological activity. OPCs have moderate bioavailability (10-15% for monomers/dimers; lower for oligomers). Enhancement: trans-resveratrol in piperine combination increases bioavailability 1544% (clinical data); cyclodextrin complexation improves aqueous solubility 400x; nanoparticle formulation; liposomal delivery. Traditional Drakshavaleha preparation with ghee may enhance lipophilic compound absorption.
Optimal Timing: Soaked Munakka in the morning on empty stomach for mild laxative effect; juice/Avaleha after meals for digestive and tonic purposes; at bedtime with milk for Rasayana effect
Standardized Extract: Grape seed extract (GSE): standardized to NLT 95% total polyphenols and NLT 80% OPCs (oligomeric proanthocyanidins) by UV spectrophotometry. Resveratrol extract: NLT 50% trans-resveratrol. Whole fruit extract ratio 4:1.
Shelf Life: 1 year (whole dried fruit in sealed pack); 2 years (powder); 3 years (GSE capsule/tablet); 1 year (Avaleha)
Storage: Dried fruit: airtight, moisture-proof packaging below 25 deg C - susceptible to moisture absorption and microbial growth. Extracts and capsules: cool, dry place, light-protected. Avaleha: airtight glass/food-grade container at room temperature.
Marker Compounds: trans-Resveratrol, Oligomeric proanthocyanidins (OPCs), Catechin, Epicatechin, Quercetin-3-glucoside, Malvidin-3-glucoside (anthocyanin), Gallic acid
Extraction Methods
- Cold-pressing of fresh grapes for juice
- Hydroalcoholic extraction of dried fruit (70:30 ethanol:water)
- Ethyl acetate extraction for polyphenol-rich fraction
- Supercritical CO2 for resveratrol extraction from grape seeds/skin
- Enzymatic extraction for enhanced OPC yield
Synergistic Combinations
- With Amalaki for antioxidant synergy and Rasayana effect
- With Yashtimadhu for respiratory and GI soothing combination
- With Pippali for enhanced resveratrol bioavailability
- With Guduchi for immune-tonic (Rasayana) formulation
- Used as Anupana (vehicle) for many formulations due to mild, sweet nature

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.

Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
