We are surrounded by viruses and other microbes with which we share a symbiotic and, mostly, healthy and supportive relationship. Some microbes are pathogenic, and some become pathogenic if they proliferate without being kept in check. A healthy immune system works in collaboration with viruses and microbes to maintain internal equilibrium and resilience.

 

COVID-19 is a novel virus with mild to severe symptoms. In most cases people are not even aware they are infected; between 80 and 95% of those infected (depending on their background health) experience no symptoms or mild ‘flu-like symptoms and recover without ill effect. Some people, particularly the very elderly and people who have underlying serious or chronic co-morbidities, experience severe or acute symptoms (a chronic cough, chest tightness, shortness of breath, cognitive dysfunction and extreme fatigue), which may last five to seven days; these symptoms may linger for up to twelve weeks, or even longer in some cases (Post COVID-19 Syndrome).

 

One of the less severe, but non-the-less distressing, symptoms of COVID-type infection is the loss of the sense of smell. Recent research indicates that essential oils have a significant role to play as aids to recovery of viral initiated loss of sense of smell.

 

While viral infection may ‘take down’ the ability of olfactory neurons to register scent molecules, some scent molecules can still traverse the epithelium and directly enter the brain. Smelling a scent, while also at the same time accessing memories evoked by that scent, may initiate related feelings and sensations, even imagination, in a way that in turn may begin to re-awaken or stimulate olfactory neural pathways. Essential oil molecules may also aid tissue regeneration and repair of the olfactory epithelium.

 

Putting this to the test, four essential oils (clove, eucalyptus globulus, lemon and rose) were selected for ‘smell training’ exercises. These oils express a diverse and complex range of scent nuances between them, yet each essential oil exudes its own unique and distinctive odour quality. These scents also express odour qualities that correlate with three of the four basic tastes (sweet, bitter and sour). Indeed, forty five per cent of smell training participants regain their sense of smell. (Hopkins 2021, Hummel 2018, 2009)

 

Along with their sensual qualities, these oils are also anti-viral and anti microbial, and may also evoke various psycho-emotional responses that may alleviate other post-viral symptoms of COVID-19, such as fatigue, depression, and lack of concentration, while also staving residual infection and averting further viral spread.
