Monoterpenes, a class of terpenes found in essential oils of many plants such as eucalyptus, pine, and citrus, have been traditionally used in various herbal medicine systems to support the treatment of cough, particularly those described as "damp" in Traditional Chinese Medicine (TCM) and similar frameworks. The rationale for their use is based on their aromatic, expectorant, and sometimes mild antiseptic properties. For example, compounds like cineole (eucalyptol) and limonene are believed to help loosen mucus and make coughs more productive, thereby "drying" dampness in the lungs.

There is limited but suggestive scientific evidence supporting some of these traditional uses. A few in vitro and animal studies indicate that certain monoterpenes can modulate mucus secretion, possess anti-inflammatory effects, and may have mild bronchodilatory actions. Cineole, in particular, has been studied for its ability to improve symptoms in bronchitis, which often includes cough with excess sputum. However, robust clinical trial data specifically linking monoterpenes as a group to the treatment of "damp cough" is lacking. Most evidence remains preclinical or anecdotal, and definitions of "damp" cough are not standardized in Western medicine.

In summary, the use of monoterpenes for cough (damp) is primarily rooted in traditional herbal practices, with some preliminary scientific investigation but without strong or conclusive clinical validation.
