Expel is the best airway supplement for horses with upper respiratory congestion. It helps lift and liquify congestion to free the airway of mucous.
The airway in horses can become congested by airborne allergens such as dust, pollen and molds. If the airway is not kept free of these particles, then
secondary bacterial infections can take hold or even acute or chronic conditions such as heaves to equine pneumonia.
It is best practise to reduce the mucous and take practical steps to reduce allergens.
In some cases, horses also require Expel with coughs and colds, freeing mucous from the airway.
