Key Constituents
Leaf essential oil dominated by 1,8-cineole (eucalyptol, typically 70%+), the principal compound responsible for the plant's antimicrobial, anti-inflammatory and expectorant/decongestant activity.
Principal immunomodulatory constituents, the main focus of anticancer-adjunct and immune research.
Bitter triterpenes associated with anti-inflammatory, hepatoprotective and adaptogenic activity.

Safety, Cautions & Contraindications
Eucalyptus globulus essential oil is highly concentrated and rich in the monoterpene 1,8-cineole; it should never be applied undiluted to the skin or ingested outside of standardized pharmaceutical preparations. Improper use can cause irritation, nausea, dizziness, or neurological symptoms, and inhalation at high concentrations may provoke respiratory distress, particularly in infants, young children, or individuals with asthma or other airway sensitivities. For this reason, essential oil use is generally discouraged in children and during pregnancy unless under professional guidance. Preparations such as leaf-infused oils or external applications using whole plant material are considerably milder, but they should still be used with care and an understanding that different preparation methods carry different levels of risk.
Duke (2002) provides clinical evidence (score 2) for eucalyptus as an expectorant and topical hyperemic (rubefacient), consistent with Commission E approval. Clinical evidence also supports its use in asthma, bronchitis, and catarrh. The essential oil (primarily 1,8-cineole) is the active constituent. Therapeutic use as steam inhalation is well-established. Internal use of the essential oil at high doses is contraindicated due to toxicity; even small amounts (3.5 ml) can be fatal in children. Contraindicated for inflammatory diseases of the gastrointestinal tract or bile ducts (Duke, 2002).
Generally well tolerated at standard doses. May cause mild digestive upset, dry mouth, or dizziness in some individuals. May enhance the effects of anticoagulant and antihypertensive medications. Avoid during pregnancy and breastfeeding. Extended use beyond 6 months is not well studied in humans.
Duke (2002) rates reishi (Ganoderma lucidum) as + and notes immunostimulant, hepatoprotective, antioxidant, antitumor, and hypoglycemic activities at the experimental level (score 1). It is a key adaptogen in traditional Chinese medicine, valued for its polysaccharide (beta-glucan) content. Duke notes antiviral (score 1) and anti-aggregant activities. No strong clinical trials existed at time of publication, but lentinan and polysaccharide fractions from related species show immunomodulatory potential. Duke suggests caution in bleeding disorders due to anti-aggregant activity (Duke, 2002).

Botanical Description
Large, fast-growing evergreen tree with distinctive two-stage leaves: rounded, silvery-blue juvenile leaves borne in opposite pairs, giving way to narrow, sickle-shaped, aromatic, dark green mature leaves as the tree ages. Small, cream-white, fluffy flowers with numerous stamens are borne singly or in small clusters, followed by a woody, cup-shaped seed capsule ('gum nut').[12]
Bracket (shelf) fungus (not a true plant) that grows on the trunks and stumps of deciduous trees. It develops a hard, kidney- or fan-shaped cap with a glossy, varnished, red-brown to mahogany crust and concentric growth rings, often on a lateral woody stalk; the pale underside is covered in fine pores that release rusty-brown spores. The mycelium spreads through the wood substrate before fruiting.[1]
Habitat
Native to south-eastern Australia and Tasmania; widely planted worldwide in warm-temperate and Mediterranean climates for timber, essential oil production and as an ornamental/windbreak tree.
Grows as a wood-decay fungus on the stumps and trunks of deciduous trees (notably maple and other hardwoods) in East Asian forests; also widely cultivated commercially on hardwood logs or sawdust substrate.
Harvesting
Mature leaves are picked or pruned year-round and used fresh, dried, or steam-distilled for essential oil, which is the main commercial and medicinal form.
Wild fruiting bodies are collected once mature; cultivated material is harvested from logs or substrate at maturity, then dried and processed into slices, powder or extract.
Traditional Uses
Eucalyptus leaf has a long Australian Aboriginal and, after global spread, worldwide tradition as a respiratory remedy - inhaled as steam or applied as chest rubs for colds, coughs, bronchitis and catarrh - and as a topical antiseptic and rubefacient for minor wounds and muscular aches.[12]
Reishi/lingzhi, the 'mushroom of immortality', is one of the most revered tonic fungi in traditional Chinese medicine, used for centuries to support vitality, calm the spirit, strengthen immunity and promote longevity; this traditional tonic reputation is now studied for immunomodulatory, anticancer-adjunct and metabolic effects.[1, 4]
Preparations
A few drops of essential oil, or fresh/dried leaf, added to hot water and the vapour inhaled for respiratory congestion; the classic and best-established use.
Diluted essential oil in a carrier oil or standardised ointment applied to the chest and back for coughs and colds.
Comminuted dried leaf infused in 150 ml boiling water, 1.5-3 g up to four times daily (daily dose 4.5-12 g) for oral use per the EU herbal monograph. Educational reference only, not a prescription.
Dosage
The EU herbal monograph on eucalyptus LEAF gives, for inhalation, 3 g of the comminuted leaf in boiling water up to 3 times daily (daily dose 3-9 g), and for oral use 1.5-3 g in 150 mL as an infusion up to 4 times daily (daily dose 4.5-12 g), in adolescents, adults and elderly. Use is CONTRAINDICATED in children under 30 months, and not recommended under 12 years. The essential oil is a separate herbal substance with its own monograph and its own posology - it is never taken internally or applied undiluted to skin on the strength of these leaf figures. Educational reference only, not a prescription.
