Cinnamaldehyde

Cinnamaldehyde is a naturally occurring flavonoid that gives the spice cinnamon its flavour and odour. It occurs naturally in the bark of cinnamon trees and other species of the genus Cinnamomum such as camphor and cassia.

Sensitivity to cinnamaldehyde may be identified with a clinical patch test.

Cinnamaldehyde is approved by the FDA for use within allergenic epicutaneous patch tests which are indicated for use as an aid in the diagnosis of allergic contact dermatitis (ACD) in persons 6 years of age and older.
