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.
Diterpenoid erinacines (concentrated in the mycelium) and aromatic hericenones (in the fruiting body) are the signature low-molecular-weight compounds that stimulate nerve growth factor synthesis and underlie the mushroom's neurotrophic and neuroprotective effects.

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).
Mild gastrointestinal upset (nausea, bloating, diarrhoea) is the most common side effect. Rare allergic reactions can occur, particularly in individuals sensitive to mushrooms, and it may slightly lower blood sugar or have mild blood-thinning effects, so caution is advised for people on diabetes or anticoagulant medications.

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]
Wood-decay fungus (not a true plant) forming a distinctive rounded, cushion-like fruiting body covered in long, dangling, tooth-like spines rather than gills or pores, resembling a white or cream 'lion's mane' or icicle cluster. It grows as a single mass rather than a typical cap-and-stem mushroom, on wounds or dead wood of hardwood trees.
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 on wounds, dead or dying wood of hardwood trees (notably oak and beech) in temperate forests of the Northern Hemisphere; 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 used fresh, dried, or processed into mycelium-based supplements.
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]
Lion's mane has a long East Asian culinary and medicinal tradition, valued in Chinese and Japanese medicine as a digestive tonic and, more recently, intensively studied for its unique ability to stimulate nerve growth factor, giving it a modern reputation as a neurotrophic and cognitive-support mushroom.[1]
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.
Fruiting-body or mycelium extract standardised to erinacine or hericenone content, taken as capsules or powder; the form used in most clinical cognitive-support studies.
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.
A 49-week double-blind randomised trial in mild Alzheimer's disease used three erinacine A-enriched H. erinaceus mycelia capsules per day at 350 mg per capsule, i.e. 1050 mg daily. Other clinical studies of cognitive support commonly use around 1-3 g of dried fruiting body extract daily. Educational reference only, not a prescription.
