Pharmacology

Medicinal Use

In rheumatism, asthma, spasmodic throat troubles, increases cardiac action, chronic bronchitis, skin diseases and for burns (essential oil of leaf and aerial part); in sporadic fevers (alcohol extract of bark and leaf); alleviating spasms (leaf); for relieving coughs and colds, sore throats and other infections (leaves essential oil); in the treatment of diarrhoea and bladder inflammation, externally it is applied to cuts etc (resin); in the form of a tincture in asthma and chronic bronchitis (dried leaves).

Contraindication

Eucalyptus oil should not be used by infants and children under the age of two, especially near the face and nose, due to the risk of airway spasm and possible cessation of breathing.Eucalyptus should not be used in large amounts by people with low blood pressure as it may cause a further drop in blood pressure.Although there are no known reports of drug interactions, the German Commission E monograph suggests that because eucalyptus oil may activate certain enzyme systems in the liver, it may potentially weaken or shorten the action of some medications, including pentobarbital, aminopyrine, and amphetamine (Blumenthal et al., 1998 and Brinker, 1997).
