Cinnamon allergies in children, though rare, can manifest in various ways, including a unique symptom of swollen ankles. This allergic reaction occurs when a child's immune system mistakenly identifies cinnamaldehyde, a compound found in cinnamon, as harmful, triggering an inflammatory response. In some cases, this can lead to localized swelling in the lower extremities, such as the ankles, due to fluid retention or histamine release. Symptoms may also include itching, hives, or mild respiratory discomfort. While not typically life-threatening, cinnamon allergies can cause discomfort and may require medical attention if swelling persists or worsens. Parents should consult a pediatrician for proper diagnosis and avoid exposing sensitive children to cinnamon in foods, spices, or even scented products like lotions or candles.
