Eucalyptus (Eucalyptus globulus)
Eucalyptus
Eucalyptus (Eucalyptus globulus) in the eucalyptus family (Myrtaceae) is a tall evergreen tree with dark blue-green aromatic leaves, native to Australia, but now cultivated worldwide.1
History and Traditional Use
In traditional medicine eucalyptus was used as an expectorant and stimulant in respiratory ailments, as well as to reduce fevers, and for its antiseptic effects.1 It was also used topically for wounds, ulcers, burns, and other skin conditions. Extracts of the leaves were used to treat joint pain, ringworm, dysentery, and pulmonary tuberculosis.1
Modern Medicinal Use
Eucalyptus leaf and oil are approved by the German Commission E for inflammations of the respiratory tract, and eucalyptus oil is also approved for external use for rheumatic complaints.2 Eucalyptus leaf has deodorant, cooling, antiseptic, and expectorant actions.3 In addition, a compound herbal tincture containing eucalyptus has been used in the treatment of ear inflammations.4 In France, acute benign bronchial disease and nasal congestion from the common cold are both treated with eucalyptus leaf.5 Both eucalyptus oil and eucalyptol (a chemical constituent of the oil) have demonstrated strong antibacterial action against Streptococcus.1 The Indian Pharmacopoeia lists the oil as a counterirritant and mild expectorant,6 and The Pharmacopoeia of the People’s Republic of China lists it as a skin irritant used in nerve pain.7 The Ayurvedic Pharmacopoeia suggests topical application of eucalyptus for a cold headache.8
Modern Consumer Use
Eucalyptus oil is used as a flavoring agent and expectorant in cough drops, syrups, and other cold medications such as vapor rubs and ointments.1 In Germany, the leaf is a standard medicinal tea for inflammation of the throat and bronchitis.9 It is commonly found in toothpastes, mouthwashes, and as a fragrance component in perfumes, lotions, soaps, and detergents.1 The oil and leaf are employed for their deodorant with cooling action.3 It is also used in massage oils, and alleviates tension headache when applied to the forehead.10
