Key Phytochemical Constituents

  • Allicin (diallyl thiosulfinate)
  • Diallyl disulfide (DADS)
  • Diallyl trisulfide (DATS)
  • Ajoene (E- and Z- forms)
  • S-allyl cysteine (SAC)
  • Alliin (S-allyl-L-cysteine sulfoxide)
  • Selenium (micronutrient)
  • Quercetin

How does it work?

  • Cardiovascular protective: Allicin and ajoene inhibit platelet aggregation, reduce LDL oxidation, and enhance NO-mediated vasodilation; DADS activates Nrf2-dependent antioxidant pathways
  • Antimicrobial: Allicin disrupts bacterial membranes and inhibits thiol-dependent enzymes; effective against S. aureus, E. coli, P. aeruginosa, and H. pylori
  • Anticancer: DATS and ajoene induce G2/M cell cycle arrest, activate intrinsic apoptotic pathway, and inhibit angiogenesis through VEGF suppression

Which traditional uses are supported by research?

  • Cardiovascular protection (Hridya, Raktachapa-hara) extensively validated through clinical trials showing reduction in blood pressure, cholesterol, and platelet aggregation
  • Antimicrobial use (Krimighna) confirmed against broad spectrum of pathogens including antibiotic-resistant bacteria (MRSA)
  • Antidiabetic use supported by clinical evidence of improved insulin sensitivity and reduced fasting blood glucose in type 2 diabetes patients

What do recent clinical trials show?

Recent safety updates

  • Generally safe at culinary doses; concentrated supplements may increase bleeding risk due to antiplatelet effects; caution with anticoagulants (warfarin), antiplatelet drugs, and pre-surgery
  • May cause GI irritation, heartburn, body odor, and halitosis; allergic contact dermatitis possible; WHO has established safety profile but notes drug interaction potential

Dosage forms and preparation

Dosage Forms: Churna (powder), Capsules (enteric-coated), Softgel capsules (oil-based), Tablets, Svarasa (fresh juice), Ksheerapaka (milk decoction), Aged garlic extract capsules, Paste

Standard Dosage: 2-5 g fresh bulb per day; 500-1500 mg standardized extract daily; 2-5 mL garlic oil; 300-600 mg aged garlic extract twice daily

Bioavailability: Allicin has poor bioavailability due to rapid degradation in GI tract; converted to diallyl sulfides which are well absorbed. Enteric coating preserves alliinase activity and improves allicin release in small intestine. Aged garlic extract (S-allylcysteine) shows near-complete oral bioavailability (~98%). Oil-macerated preparations deliver diallyl sulfides with good absorption.

Optimal Timing: With meals to reduce GI irritation; evening dosing may be preferred for cardiovascular effects due to nocturnal blood pressure dipping

Standardized Extract: Enteric-coated powder standardized to minimum 1.3% alliin (yielding 0.6% allicin potential). Aged garlic extract standardized to 1.0-1.5 mg S-allylcysteine per dose. Garlic oil macerate standardized to 2-5 mg diallyl thiosulfinates per capsule.

Shelf Life: 36 months for enteric-coated tablets; 24 months for softgels and aged garlic extract; 12 months for fresh juice/paste

Storage: Store below 25 deg C in airtight containers. Protect from moisture. Enteric-coated products should be kept in blister packaging with desiccant. Garlic oil capsules require nitrogen flushing to prevent oxidation. Fresh preparations require refrigeration at 2-8 deg C.

Marker Compounds: Alliin, Allicin, S-allylcysteine (SAC), Diallyl disulfide (DADS), Diallyl trisulfide (DATS), Ajoene, Allyl methyl sulfide

Extraction Methods

  • Steam distillation for volatile oil
  • Cold pressing/maceration in oil
  • Aqueous extraction for aged garlic
  • Freeze-drying to preserve alliinase
  • Hydroalcoholic extraction (40% ethanol)
  • Supercritical CO2 extraction

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.
