Guaiapate is commonly used in the pharmaceutical and healthcare industries due to its expectorant properties. It is often included in cough syrups and cold medications to help loosen and expel mucus from the respiratory tract, providing relief from congestion and facilitating easier breathing. Additionally, it is utilized in formulations aimed at treating bronchitis and other respiratory conditions, where clearing the airways is essential for recovery. Its soothing effects on the throat also make it a valuable component in throat lozenges and related products designed to alleviate irritation and discomfort caused by coughing.
