In Traditional Chinese Medicine, the three levels of Qi (consciousness/experience) are Wei Qi, Ying Qi and Yuan Qi. In aromatherapy terms, these levels relate to the fragrance notes of essential oils: the top notes, middle notes and base notes respectively.
Top note oils (the Wei level)
The Wei level is associated with the outer and most superficial level of our consciousness and experience. Wei level oils have a close relationship with our lungs and breath. Like the wind, these essential oils are the most volatile and have an effect on acute conditions of the upper body. Oils with top notes include all the essential oils that are distilled from peels and many that are distilled from leaves. Common examples are lemon, orange, peppermint and Eucalyptus radiata. Top notes are often used for treating common colds, to quickly uplift someone’s mood by diffusing or inhaling the oil, or as a refresher at the end of a massage treatment. Wei level oils are the least thick, or viscous, of all the essential oils. They evaporate quickly, typically within 45 minutes to two hours. They do not penetrate the Ying or Yuan levels.
Middle note oils (the Ying level)
From the external Wei levels, we move to the Ying level. The Ying level is associated with organ Qi, postnatal Qi, blood and emotions. Essential oils that can strengthen our immune and digestive systems and support our muscular system are associated with Ying level. These oils are middle notes, and they last longer than top notes.
Ying level oils include tea tree, which is famous for its ability to strengthen the Lung Qi: Roman chamomile, which is regarded as one of the best oils to use to support the digestive system; and lemongrass (also known as the tendinomuscular oil), which helps to promote the movement of Qi and alleviate muscular pain.
Base note oils (the Yuan-source level)
The deepest and most mysterious level is that of Yuan Qi – the Yuan (source) level. This level is closely associated with DNA and our potential, and is connected to our Jing. Oils with base notes are derived from resins, woods and roots, as well as some flowers, and they are the thickest essential oils. They are often used to treat chronic conditions and are also great to use for descending our Qi (directing our energy downward). Yuan level oils are associated with the most Yin aspect of our being, they are often used to treat symptoms that manifest in the evening hours, such as insomnia and night sweats. Apply these oils in the evening as this correlates with their Yin nature and will improve their effectiveness. Common examples are spikenard, sandalwood, vetiver, and rose.
