Rating (out of 5): 2

Cinnamaldehyde, the main active component of cinnamon (Cinnamomum spp.), is primarily used in traditional medicine systems, such as Traditional Chinese Medicine (TCM) and Ayurveda, for the management of cough, particularly dry cough. In these practices, cinnamon and its extracts have long been valued for their warming properties and ability to promote circulation, which are believed to help relieve respiratory discomfort, including cough. Some herbal cough remedies and teas incorporate cinnamon or cinnamaldehyde-containing preparations for this reason.

However, there is limited direct scientific evidence supporting cinnamaldehyde’s efficacy specifically for treating dry cough in humans. Some in vitro and animal studies suggest that cinnamaldehyde possesses anti-inflammatory, antimicrobial, and mild bronchodilatory effects, which could theoretically contribute to cough relief. For example, cinnamaldehyde has shown the ability to inhibit certain bacteria and viruses associated with respiratory tract infections, and may modulate inflammatory pathways. Despite these findings, clinical studies directly evaluating cinnamaldehyde for dry cough are lacking.

In summary, the use of cinnamaldehyde for dry cough is primarily rooted in traditional medicinal use, with only modest indirect scientific support from its general biological activities. Its effectiveness for this specific condition in humans has not been rigorously established through clinical research.
