According to a study published by "BMC complementary medicine and therapies", the bark essential oil of Cinnamomum verum is used for its potential to inhibit acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). This essential oil demonstrated potent activity with IC50 values of 453.7 µg/mL for AChE and 184.7 µg/mL for BChE. At specific concentrations, it showed 62.64% inhibition against BACE1 at 500 mg/mL and 41.79% inhibition at 100 mg/mL. Chemical analysis via GC-MS identified the major constituent, (E)-cinnamaldehde, at 68.23%. The potent BChE inhibitory activity of this oil suggests it could be developed into cinnamon based dietary supplements for managing advanced Alzheimer's disease.
