Cinnamon is generally safe to use in medicinal concentrations,although allergic skin and mucous membrane reactions are always a possibility and a particularly high risk with cinnamon-flower preparations.These are reports of people experiencing allergic reactions to cinnamon in chewing gums,and of asthma and dermatitis symptoms such as skin itching and irritation developing in spice factory workers and others who have frequent and heavy contact with cinnamon powder.If you take very large doses of cinnamon bark,you risk developing unpleasant symptoms such as a fast heartbeat and increased breathing,sweating,and intestinal function,ultimately followed by sedation and other signs of central nervous system slowdown.Moderate amounts of cinnamon oil may cause the same reaction.German health authorities warn that pregnant women and people with stomach or intestinal ulcers should avoid medicinal concentrations of cinnamon.People who are allergic to cinnamon or even balsam of Peru should probably avoid it altogethor.Avoid ingesting cinnamon oil,which is highly concentrated;it can cause nausea,vomiting,and even kidney damage in certain cases.Sometimes applying it to the skin causes redness and burining sensations.

No health hazards or side effects are known in conjunction with the proper administration of designated therapeutic dosages.The drug possesses a medium potential for sensitization,primarily due to the cinnamaldehyde.Pregnancy:the drug is not to be administered in time of pregnancy.
