Inshanti Pure Essential Oils is offering a new set of four Scent School inhalers for $25: Eucalyptus Globulus, Lemon, Lavender and Clove, with directions on how to use them to gain the sense of smell back after losing it to COVID-19 or for some other reason.

According to a January 2022 study, 68 percent of people report losing their sense of smell and taste as a symptom of COVID-19. Olfactory neurons, which are responsible for smell and taste, are capable of regeneration, and these four inhalers when used correctly, may help. It requires time, patience and consistency.
