Eucalyptus Smithii Organic, Eucalyptus smithii (1439) (also known as Gully Ash) is lighter than Eucalyptus Globulus, and has a fresh, sweet, dry aroma. It has a softer, gentler quality than other species of Eucalyptus, and is often preferred for use with children, older people, and in fact anyone with a particularly sensitive nature. Its softer quality makes it well-suited for long-term use. Eucalyptus Smithii has many of the qualities of other Eucalyptus, stimulating the body to fight against germs, and having a balancing, refreshing and even inspirational effect. It is soothing for the muscles. This is an aromatherapy essential oil from South Africa, and is obtained from the leaves.
