In a 2000 study published in The Indian Journal of Medical Research, it was shown that of the 69 plant species screened, 16 were effective against HIV-1 and 4 were against both HIV-1 and HIV-2. The most effective extracts against HIV-1 and HIV-2 were respectively Cinnamomum cassia (bark) and Cardiospermum helicacabum (shoot + fruit).

Pharmacological experiments suggest that the cinnamon-derived dietary factor cinnamic aldehyde (cinnamaldehyde) activates the Nrf2-dependent antioxidant response in human epithelial colon cells and may therefore represent an experimental chemopreventive dietary factor targeting colorectal carcinogenesis. Recent research documents anti-melanoma activity of cinnamic aldehyde observed in cell culture and a mouse model of human melanoma.
Cinnamon bark, a component of the traditional Japanese medicine Mao-to, has been shown in a 2008 study published in the Journal of General Virology to have an antiviral therapeutic effect.
A 2011 study isolated a substance (CEppt) in the cinnamon plant that inhibits development of Alzheimer's in mice. CEppt, an extract of cinnamon bark, seems to treat a mouse model of Alzheimer's disease.
