Composition
Lavender oil, myrtle oil, lemon oil, manuka oil.
The plants and the oils
Lavender oil is steam-distilled from the freshly cut flowering tops of lavender.[2] Its main components include linalyl acetate and linalool.[3]
Myrtle oil is distilled in the same way from the leaves and twigs of common myrtle (Myrtus communis).[2] Green myrtle, generally from Corsica, contains much more alpha-pinene, and red myrtle much more 1,8-cineole.[4]
Lemon oil is usually cold-pressed from the peel of the lemon (Citrus limon); steam-distilled lemon oil is also sold. Limonene gives it its lemony scent.[5]
Manuka oil is likewise steam-distilled from mānuka (Leptospermum scoparium). Its composition varies with where it grows: oil from the East Cape of New Zealand is rich in triketones, known for strong antibacterial properties, while mānuka grown in Australia has almost none.[6]
Scent
- Myrtle: sweet, fresh, green and slightly camphorous; red myrtle smells more camphorous because it has more 1,8-cineole.[4]
- Lavender: floral, fresh, sweet and herbal, sometimes slightly fruity or camphorous.[3]
- Lemon: pressed oil is fresh, bright and zesty, like a freshly peeled lemon; steam-distilled oil smells softer and sweeter.[5]
- Manuka: woody, earthy and balsamic, without the medicinal note of tea tree oil.[7]
Where it sits in a blend. Lemon is a strong top note.[5] Myrtle and lavender are top to middle notes.[4][3] Manuka is a middle note with some base-note character, a bridge between the two.[7]
How to use
- The blend is intended for use on high mountain hikes and during active sport.[1]
- In aromatherapy, myrtle oil is used for respiratory complaints, bronchitis, coughs and colds,[4] and manuka oil for bronchitis, catarrh (excess mucus) and coughs.[7]
Asthma. Fragrances, natural ones included, can make asthma worse, so treating it by inhalation carries some risk.[8] People with asthma or another lung disease should keep to the treatment their doctor prescribed and ask the doctor before inhaling essential oils.
From a tissue. Put a few drops on a tissue and breathe in.
- Add 8-10 drops to a bowl of hot water.
- Breathe in the vapour. Keep the oil away from the eyes.[9]
- Stop if the vapour makes you cough; aromatherapy with lavender oil may cause coughing or headache.[10]
Storage. Store at room temperature (15-25 °C) and close the bottle after use: citrus oils that have oxidised (changed through contact with air) can sensitise the skin.[9]
Precautions
- do not swallow the oil;[11]
- keep it away from the eyes;[9]
- keep the bottle out of the reach of children.[9]
- If the blend gets on the skin, keep that area out of the sun: expressed lemon oil is phototoxic and can cause burning or changes in skin colour in sunlight.[9]
- Topical products containing lavender may cause allergic skin reactions in some people.[10]
- Myrtle oil itself contains estragole and methyleugenol, so at most 1.9% of myrtle oil is recommended on the skin.[4]
- Young children are more sensitive to essential oils than adults.[9]
- Properly diluted, lavender and lemon oils appear to be safe in pregnancy.[9]
- The oil is highly flammable: keep it away from candles and open flames.[9]
