This is a common query from regular Covonia users. The most likely explanation for this experience is that the bottle was not adequately shaken. Some of the natural oils used in the formulation tend to separate to the surface when the bottle is at rest and therefore the product carries the instruction to “shake the bottle vigorously” before use.
Covonia Mentholated Cough Mixture provides symptomatic relief of chesty coughs and sore throats. Liquorice and Squill belong to a group of medicines known as expectorants. They help remove phlegm in people with chesty coughs. Menthol also acts to relieve congestion associated with chesty coughs and bronchitis.
