Shigru Patra

Shigru Patra

Moringa oleifera

Shigru Patra (Moringa oleifera) is a plant used in Ayurveda. Heat processing above 70 deg C inactivates myrosinase and reduces isothiocyanate formation — use raw or mildly heated preparations. Quercetin and kaempferol glycosides show moderate bioavailability (20-35%).

Dosage forms and preparation

Dosage Forms: Churna (powder), Capsule, Tablet, Swarasa (fresh juice), Tea/Infusion, Vati (tablet), Granules

Standard Dosage: 3-6 g leaf powder per day; 500-1000 mg standardized extract capsule twice daily; 10-20 mL swarasa daily; 1-2 cups infusion daily

Bioavailability: Isothiocyanate compounds (derived from glucosinolates by myrosinase activation) show good oral bioavailability (50-70%) when consumed from fresh/minimally processed leaves. Heat processing above 70 deg C inactivates myrosinase and reduces isothiocyanate formation — use raw or mildly heated preparations. Quercetin and kaempferol glycosides show moderate bioavailability (20-35%). Iron and calcium from leaves have moderate bioavailability (10-20%), enhanced by vitamin C content.

Optimal Timing: Morning with breakfast for nutritional supplementation; before meals for blood sugar management

Standardized Extract: Freeze-dried leaf powder retaining NLT 0.5% total isothiocyanates (as moringin equivalents); standardized extract (5:1) NLT 3% total flavonoids (as quercetin equivalents) and NLT 1% chlorogenic acid by HPLC

Shelf Life: 18 months for leaf powder in nitrogen-flushed packets; 24 months for capsules; 12 months for tea bags

Storage: Store below 25 deg C in airtight, light-proof containers. Nitrogen-flushed packaging critical for powder to prevent chlorophyll degradation and lipid oxidation. RH <50%.

Marker Compounds: Moringin (4-(alpha-L-rhamnopyranosyloxy)benzyl isothiocyanate), Quercetin-3-glucoside, Kaempferol-3-glucoside, Chlorogenic acid, Beta-carotene, Niazimicin, Niazirin

Extraction Methods

Low-temperature aqueous extraction (<50 deg C to preserve myrosinase)
Hydroalcoholic extraction (50-60% ethanol)
Fresh leaf juice (cold pressing)
Spray-drying of aqueous extract at low temperature
Freeze-drying for maximum nutrient and enzyme preservation

Synergistic Combinations

Amalaki (vitamin C enhances iron absorption from Moringa)
Haridra (anti-inflammatory-nutritive combination)
Ashwagandha (adaptogenic and nutritive synergy)
Guduchi (immunomodulatory formulations)
Spirulina (comprehensive nutritional supplement)

Published research

Literature indexed in PubMed that concerns this subject, grouped by study type. A paper appearing here is a record of what has been published, not evidence that the subject works, and laboratory or animal results do not transfer to people. Study titles link to PubMed so you can read the source rather than take our word.

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.

Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. 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.
