Indications: King’s American Dispensatory describes the uses this plant was put to by the eclectics. Here are some relevant quotes:”Eucalyptus globulus has for a long time been known as a remedy for intermittent fever among the natives of the countries of its origin. Aside from its alleged utility in intermittents, this agent has had other virtues attributed to it, as follows: The leaves and their preparations have been successfully used as a tonic and gently stimulating stomachic, in atonic dyspepsia, and in catarrh of the stomach and typhoid fever; also advised in mucous catarrhal affections generally; in pseudo-membranous laryngitis, in asthma, with profuse secretion, and in chronic bronchitis, with or without emphysema, and in whooping-cough; it has likewise proved efficient in chronic catarrh of the bladder, where the urine is high-colored, contains an abnormal amount of mucus, or, perhaps, some purulent matter, and micturation is attended with much pain. More recently it has been recommended as a diuretic in the treatment of dropsy. Both the leaves and the oil are excitants and deodorizers, and, as such, have been successfully employed as local applications in bronchial affections with fetid expectoration, in ozena, in fetid or profuse mucous discharges, in vaginal leucorrhoea, offensive lochial discharges, gonorrhoeal discharges, indolent, fetid wounds or ulcers, cancerous ulcerations, in septicemia, and in gangrene. The leaves may, in some cases, be applied alone, directly to the part, in form of cataplasm; or they may be combined with other articles to form a poultice. The oil may be applied of full strength, or diluted with some other agent. In throat and pulmonary maladies, a tincture diluted, or a medicated water, may be inhaled in the form of spray; if the oil be employed, it may be dropped on some cotton placed in a small tube, from which the vapor may be inhaled. As a deodorizer, the tincture or the oil may be sprinkled or sprayed upon the offensive body, or the atmosphere of an apartment may be frequently sprayed with the same. Externally applied, the oil gives relief in some forms of neuralgic and rheumatic pains. The leaves of Eucalyptus, made up into cigars or cigarettes, and smoked, have been advised to afford relief in bronchial catarrh, asthma, and other affections of the respiratory organs. The question has been asked, may not the small amount of benefit that might be derived from the minute proportion of oil remaining intact, be more than overcome, and even prove injurious, from the irritating action of the smoke and of the empyreumatic products.Eucalyptus honey, gathered by bees from Eucalyptus flowers, is quite active, and has been recommended for parasitic and putrescent conditions, gonorrhoea, fevers, and catarrhal diseases. It is sedative to the heart, actively diuretic, and increases the elimination of uric acid.”

Combinations: The oil is often combined with Thymus.

Preparations & Dosage: An infusion may be made with 1-2 teaspoonfuls of the leaves to a cup of boiling water. Let infuse for 10-15 minutes. The dose of tincture is 1 ml. three times a day.
