Eucalyptus Herb

Eucalyptus Herb (Eucalyptus globulus) is a plant used in Ayurveda. Aqueous infusion extracts primarily polyphenols and residual volatile oil. Polyphenol bioavailability is moderate (10-20% for flavonoids, low for condensed tannins). Ellagitannins are metabolized by gut flora to urolithins.

What is it made of?

Key Active Markers

Derived from constituent herbs (see individual herb profiles)
Standardized on primary bioactive markers

Analytical Methods: HPLC fingerprinting, TLC (identity), LC-MS/MS (marker quantification)

Dosage forms and preparation

Dosage Forms: Dried leaf infusion/tea, Churna (leaf powder), Capsule (leaf extract), Tablet, Tincture (1:5 in 45% ethanol), Poultice (crushed leaves)

Standard Dosage: 2-4g dried leaf as infusion 2-3 times daily; 500-1000mg standardized leaf extract capsule twice daily; 2-5ml tincture three times daily; poultice applied externally as needed

Bioavailability: Eucalyptus leaves contain polyphenols (tannins, ellagic acid, flavonoids) in addition to essential oil. Aqueous infusion extracts primarily polyphenols and residual volatile oil. Polyphenol bioavailability is moderate (10-20% for flavonoids, low for condensed tannins). Ellagitannins are metabolized by gut flora to urolithins. The residual essential oil (1,8-cineole) in dried leaf preparations contributes aroma and mild expectorant action but at lower levels than pure essential oil. Enhancement: standardized leaf extracts with defined polyphenol content in phytosome form.

Optimal Timing: Infusion/tea: 2-3 times daily between meals for respiratory conditions; capsule: after meals twice daily; poultice: as needed for local pain relief

Standardized Extract: Leaf extract standardized to NLT 10% total polyphenols (as gallic acid equivalent) and NLT 1% 1,8-cineole (residual essential oil). Extract ratio 5:1 to 8:1.

Shelf Life: 2 years (dried leaves in sealed packaging); 2 years (capsule/tablet); 3 years (tincture)

Storage: Dried leaves in airtight containers below 25 deg C, protected from moisture and light. Tincture: amber glass, room temperature. Tea bags: individually sealed, nitrogen-flushed for aroma retention.

Marker Compounds: Ellagic acid, Gallic acid, Rutin, Quercetin, 1,8-Cineole (residual), Eucalyptin, Macrocarpal A

Extraction Methods

Hot water infusion (tea preparation)
Hydroalcoholic extraction (60:40 ethanol:water)
Aqueous decoction
Methanol extraction for phytochemical profiling
Spray-dried aqueous extract

Synergistic Combinations

With Tulsi leaf for respiratory and immune support
With Adulsa (Adhatoda) for bronchial conditions
With Yashtimadhu for sore throat and cough
With Ginger for enhanced expectorant and warming effect

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.
