Terpin Hydrate

Terpin Hydrate is a terpene-derived crystalline compound widely known for its expectorant properties. Sourced from essential oils such as turpentine, thyme, and oregano, it facilitates the breakdown and expulsion of mucus from the respiratory tract. Historically used in mainstream respiratory medications, it is now primarily offered through compounding pharmacies for personalised respiratory care solutions.

In therapeutic practice, Terpin Hydrate is commonly blended with antitussives like codeine to manage both dry and productive coughs. By thinning mucus and easing its removal, it supports patients suffering from bronchitis, pneumonia, asthma, COPD, and other upper respiratory tract infections. Its role in enhancing airway clarity without suppressing the body’s natural defence mechanisms makes it a valuable agent in respiratory formulations.

Though withdrawn from general OTC availability in some markets due to regulatory shifts, Terpin Hydrate has retained clinical interest for its efficacy in compounded medications. It is still prescribed in specific regions and continues to serve in natural cough formulations, herbal elixirs, and wellness-based respiratory therapies.
