Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Phenylpropanoids are a broad class of plant-derived compounds that include substances such as cinnamic acid, eugenol, and coumarin, among others. Traditionally, plants rich in phenylpropanoids (such as cinnamon, clove, and star anise) have been used in various cultures to help manage symptoms of colds and other respiratory infections. The rationale for their use is rooted in traditional medicine systems, which have often valued these herbs for their aromatic properties and purported effects on the respiratory tract.

Scientific studies on the direct antiviral activity of “phenylpropanoids (unspecified)” against cold viruses (such as rhinoviruses or coronaviruses) are limited and largely preclinical. Some phenylpropanoids, like eugenol and cinnamaldehyde, have shown in vitro antiviral activity against certain viruses, but robust clinical trials in humans for the treatment of the common cold are lacking. Therefore, while there is some laboratory evidence of potential antiviral effects, the primary justification for their use in colds is traditional, based on the historical use of phenylpropanoid-rich plants rather than direct scientific validation. The evidence supporting their use for this purpose is rated low (2/5), reflecting that while traditional use is extensive, rigorous scientific evidence is sparse.
