Although Eucalyptus radiata shares a common cineole aroma with other eucalyptus oils, analytically it is unique. The primary difference is the presence of the constituent, piperitone, also a component of peppermint. Other than that, the aroma is quiet similar to Eucalyptus globulus, which has the traditional eucalyptus aroma. Davis notes that radiata is more easily assimilated and less likely to irritate the skin or mucus membrane.
Plant Origin: Australia
Method: Steam distilled from leaves
alpha-Terpinyl acetate 2.21%
Eucalyptus radiata is very similar to Eucalyptus globulus; they only differ in minor components. E. radiata is often preferred for children and the elderly over the common E. globulus, because it is more gentle on the skin. Also consider Eucalyptus smithii or Rosalina for children and the elderly. It is a powerful antiviral oil that may help control microbes, fortify resistance and for general immunity. Please refer to safety information below.
Properties and Usage
Eucalyptus radiata is antibacterial, antiviral, expectorant, anti-inflammatory
It is useful for respiratory and sinus infections, bronchitis, coughs, is a decongestant, is helpful for rheumatism, arthritis, joint and muscle pain. Combine Eucalyptus Radiata with Bergamot to effectively fight Herpes simplex. Acne, immune system stimulent, flu, ear infection, vaginitis.
Viruses: Penoel suggested that a-terpineol and the oxide 1,8 cineole should be administered. The oils suggested in which these constituents are found are Bay Laurel, Eu. radiata and Niaouli.
Application Suggestions (See Essential Oil Usage for more information and a dilution chart.)
Topical: Dilute with a carrier oil and apply on area of concern or as desired. Many sources indicate Eu. radiata is the oil of choice for infections of the upper respiratory system.
Aromatherapist, Valerie Worwood includes Eucalyptus Radiata in the basic care kit for children (Aromatherapty for the Healthy Child page 35), but Tisserand warns that "Essential oils high in 1,8-cineol or menthol can cause CNS and breathing problems in young children, and should not be applied to or near their faces." See safety information below for more specific information.
Inhalation: Diffuse or directly inhale (directly inhalation is not suitable for young children - see safety information below. Rosalina is a good alternative for direct inhalation.)
Internal: The quality of Eucalyputus radiata is suitable for internal use within safe parameters, if such use is deemed appropriate. We feel that internal use is rarely *needed* and should only be used with respect for how concentrated the oils are. HEO does not advocate internal use of essential oils without appropriate knowledge and understanding of how to administer, for what purpose, how much, which essential oils, safety concerns and so on. In our experience, essential oils are generally more effective used topically with proper dilution or inhaled. Kurt Schnaubelt Ph.D. notes that "French aromatherapy literature contains many references to using oils orally." He goes on to note that "generally 1 drop is always enough when ingesting essential oils." A potential toxicity hazard could occur when untrained people use essential oils orally and ingest too much. Keep in mind that while medical doctors or health care practitioners may prescribe essential oils for internal use, they are trained and experienced in the safe application of essential oils. It is not a matter of using "French aromatherapy" or "British" methods, it's a matter of experience and appropriate application.
Robert Tisserand, aromatherapist and author of Essential Oil Safety writes: "Roughly, eucalyptus oil is fatal to humans taken orally at 1ml [30 drops] per age." He also notes: Maximum daily oral dose of 600mg (20 drops).

1. I had a plugged ear and runny nose today and I rubbed Eucalyptus oil on the bottom of my feet. About 10 minutes later my body felt really hot. A bit later, I have no plugged ear or runny nose. Praise the Lord! - Francine
Heritage Essential Oil blends with Eucalyptus Radiata
Aromatherapist, Valerie Worwood includes Eucalyptus Radiata in the basic care kit for children (Aromatherapty for the Healthy Child page 35), but due to more recent reports, Tisserand warns that "Essential oils high in 1,8-cineol or menthol can cause CNS and breathing problems in young children, and should not be applied to or near their faces of infants or children under ten years of age. This warning stims from a few incidents where a caregiver put 100% essential oil drops (Olbas was one brand) into the nostrils of their baby/child, which caused breathing distress. Specifically, the warning Tisserand gives is not to apply oils with 40% or more 1,8-cineole and menthol content on or near the faces of young children. Responsible parents would not do this with any essential oil. Appropriately diluted, the percentage is reduced and the oils may be used safely. Tisserand also notes that "For children of 5 years old or less, direct inhalation should be avoided. Direct inhalation induces inhaling essential oils from the hands, a cotton ball, a nasal inhaler, a bowl of hot water or similar. Indirect, or ambient inhalation, is safe for young children, and includes any method that vaporizes essential oils into the air" (page 658)."
Avoid contact with the eyes and other sensitive areas. Essential oils are both lipophilic and hydrophobic. Lipophilic means they are attracted to fat—like the membranes of your eyes and skin. They are also hydrophobic, meaning they do not like water. Flushing with water will only send the essential oil back to the eye's membranes. Applying a carrier oil will create another fat for the essential oil to be attracted to other than the membranes of the eyes or skin. We’ve not known this to cause permanent injury or long-term discomfort, but if you feel concerned, please call your health care provider.
