Terpenes are a large and diverse class of organic compounds produced by various plants, especially conifers, and they are major components of essential oils. Historically, certain terpenes—such as menthol (a monoterpene) and eucalyptol (1,8-cineole)—have been used in traditional medicine as decongestants to help alleviate symptoms of colds. Products like mentholated ointments and eucalyptus oil have long been inhaled or applied topically to the chest to provide a sensation of improved airflow and relief from nasal congestion. The traditional use is largely based on subjective reports of symptom relief and the cooling, soothing sensation these compounds provide upon inhalation.

While there is some scientific interest in specific terpenes, evidence for their effectiveness as decongestants is limited and often does not extend to all terpenes as a class. Most clinical studies focus on individual terpenes rather than the broad, unspecified category. The decongestant effect is believed to be primarily a sensory phenomenon rather than a true pharmacological action on nasal passages. Thus, the use of unspecified terpenes for treating colds as decongestants is justified mainly by tradition, with only a modest evidence base supporting specific compounds. More rigorous scientific research would be needed to validate the efficacy and safety of terpenes, in general, for this purpose.
