Abstract

The aim of present study was to investigate the possible influence and the related mechanism of Cinnamomum cassia derived-cinnamaldehyde on the inflammation or nociception. Cinnamomum cassia was referred to be treated for common cold or dyspepsia in the traditional medicine. However, there are no reports on the antinociceptive or anti-inflammatory properties of cinnamaldehyde, the primary ingredient of Cinnamomum cassia. We hypothesized that cinnamaldehyde would play a role in the modulation of inflammation or nociception evoked by carrageenan, acetic acid or heat. Male Institute of Cancer Research mice were used and the size of edema, frequency of writhing and latency of abnormal behaviors such as licking, flicking, shaking or jumping were measured and recorded. The present study was carried out to evaluate the antiinflammatory and antinociceptive effects of cinnamaldehyde. The administration of cinnamaldehyde (30 and 100 mg/kg) inhibited carrageenan-induced paw edema only at the final phase, suggesting the blockade of synthesis or release of prostaglandins. It also reduced the frequency of the acetic acid-induced writhing reflex in mice. In addition, the administration of cinnamaldehyde prolonged the latency for extraordinary reaction at the hot plate in mice. In conclusion, cinnamaldehyde has anti-inflammatory and analgesic properties and is a potential therapeutic for inflammation and nociception.
