All coughs are not the same: there is dry cough and wet cough.
Dry coughs are caused by an irritant in the air, such as physical particles or allergies, or dry air. Inhale anti-spasmodic essential oils via steam inhalation to best relieve a dry cough.
Wet coughs are accompanied by phlegm and are often paired with respiratory congestion. Inhaling expectorant, calming essential oils can benefit a wet cough.
I've formulated recipes for both dry cough and wet cough based on the best essential oils and the best methods of application.
