Cinnamaldehyde

Current working status

Cinnamaldehyde-containing foods, such as tomatoes, citrus fruits, and chocolate were identified as triggers by a separate NRS survey. Transient receptor potential ankyrin receptors-1 (TRPA1) found in sensory nerves in the dermis might be activated by cinnamaldehyde, resulting in vasodilation, and, hence, erythema, and telangiectasia by increasing edema and flushing. One case report described a 68-year-old woman with severe exacerbation of rosacea following the consumption of of cinnamon oil, a cinnamaldehyde-containing food, to lower her blood glucose (source).
