Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Terpenoids, also known as isoprenoids, are a diverse class of naturally occurring organic chemicals derived from terpenes. They are found in many plants and are the primary constituents of essential oils. The use of terpenoid-rich herbal remedies and essential oils (such as eucalyptus, tea tree, and thyme oil) for the prevention and management of colds has a strong basis in traditional medicine practices, particularly in herbal and folk medicine systems worldwide.
Historically, these essential oils have been inhaled, applied topically, or used in steam therapy to alleviate symptoms of respiratory tract infections, including the common cold. The rationale for their use is often based on their aromatic, expectorant, and perceived antimicrobial properties. For example, eucalyptus oil, rich in the terpenoid eucalyptol, has been traditionally used to relieve nasal congestion and cough.
While there is some laboratory evidence that certain terpenoids possess antimicrobial or anti-inflammatory activities, robust clinical evidence supporting their effectiveness specifically for the prevention of colds is limited. Most studies are either in vitro or in animal models, and few high-quality human trials directly address cold prevention. Therefore, their use for this purpose is primarily justified by tradition, with limited, low-strength scientific support.
