Why Can't I Smell Now? Post COVID Syndrome

A lingering long haul syndrome phenomenon and what you can do about it!

An interesting complication for some of those who have had COVID-19 is a loss of smell (anosmia) or decreased ability to smell (hyposmia). This condition is called Post Infectious Smell Loss (PISL) and some studies show that it can affect up to 10% of individuals with Post Covid Syndrome. It is thought to be related to damage to the supporting cells around the olfactory nerves. 

A Holistic Approach to Treatment

PISL rarely lasts for more than 1 month, but for some people the symptoms persist for much longer. This can adversely affect their quality of life, especially when it interferes with their ability to taste. Treatment for PISL is called olfactory training and can actually be implemented on one’s own. Prior research in this area has found that by using specific types of concentrated essential oils on a regular basis, one might regain their smell.

If you are experiencing PISL or you know someone who is, try one of the following protocols:


  • Each oil is smelled for 15 seconds for 2 rounds: in the same order. Think about what you are smelling with each oil.
