(Eucalyptus smithii) Traditionally used to support healthy breathing, immune response, bone and muscle function and to soothe wounds, insect bites and stings.
Aromatherapy Literature Notes Shirley and Len Price suggest E. smithii and Myrtle for infants with coughs/colds. At a presentation to the Royal Society of Medicine, Michael Smith (pathologist) stated that E. smithii was effective against MRSA. Penoel notes that both E. globulus and smithii contain a high level of 1,8-cineol (an oxide that can be a skin irritant), "yet the former is contraindicated for use on young children, and the latter is not" (Price, Shirley and Len). This is due to quenching, where the presence of other components nullifies the potential side effects of one component.
Purchon/Cantele wrote that E. radiata is "said to be a powerful expectorant, especially when blended with E. smithii.

Price wrote that E. smithii is antiseptic and analgesic (pain relieving), which makes it ideal for minor scrapes. Price also notes that E. smithii is most commonly used for relief of chest infections and to facilitate breathing. Price feels that E.smithii "is an excellent preventative measure for winter coughs and colds. Not only does it increase the resistance of the respiratory system to infection, it is also anticatarrhal, antiviral and an effective expectorant."
