Jati
Jasminum officinale
Jati (Jasminum officinale) is a plant used in Ayurveda. Linalool has high oral bioavailability (~70%) and crosses blood-brain barrier. Secoiridoid glycosides are hydrolyzed by gut enzymes to absorbable aglycones. Nasal administration (Nasya) provides direct CNS access bypassing first-pass metabolism.

Dosage forms and preparation
Dosage Forms: Taila (essential oil), Churna (flower/leaf powder), Kashayam (decoction), Capsule, Swarasa (leaf juice), Nasya oil (nasal administration)
Standard Dosage: 3-5g leaf powder twice daily; 30-60ml flower decoction; 5-10 drops essential oil (external or aromatherapy); 2-3 drops Nasya oil per nostril
Bioavailability: Jasminum grandiflorum (Jati/Jasmine) flowers and leaves contain secoiridoids, flavonoids, and essential oil (jasminol, linalool, benzyl acetate). Linalool has high oral bioavailability (~70%) and crosses blood-brain barrier. Secoiridoid glycosides are hydrolyzed by gut enzymes to absorbable aglycones. Nasal administration (Nasya) provides direct CNS access bypassing first-pass metabolism.
Optimal Timing: Nasya: morning on empty stomach. Internal use: after meals. Aromatherapy: as needed for relaxation.
Standardized Extract: Jasmine absolute (solvent-extracted, minimum 0.3% jasmone); leaf hydroalcoholic extract standardized to total flavonoid content; Nasya oil prepared in sesame oil base
Shelf Life: 2 years (leaf powder); 3 years (jasmine absolute, sealed); 2 years (Nasya oil); 2 years (capsule)
Storage: Essential oil/absolute in dark amber glass, tightly sealed, below 20°C. Leaf powder in airtight containers. Protect all preparations from light and heat.
Marker Compounds: Jasmone (cis-jasmone), Linalool, Benzyl acetate, Methyl jasmonate, Jasminin (secoiridoid), Oleuropein
Extraction Methods
- Solvent extraction (hexane/petroleum ether for concrete, then ethanol for absolute)
- Enfleurage (traditional cold-fat extraction for jasmine absolute)
- Hydrodistillation (low yield, <0.1%)
- CO2 supercritical extraction for high-quality absolute
- Aqueous decoction of leaves
- Oil maceration for Nasya/Taila preparations

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.
