In this study, hydrosols from Cinnamomum osmophloeum of Taimalee and different chemotypes from Chungpu, as well as commercial products were analyzed for their properties, chemical compositions, and bioactivities. The initial results suggested the leaf hydrosols of C. osmophloeum tended to have low pH and high electrical conductivity, containing high amounts of iron, manganese and trace amount of copper. Cinnamic aldehyde was the main ingredient which was effective in inhibiting the growth of Chaetomium globosum, and Penicillum citrimum. Even with 3 folds dilution, 100% inhibition was retained. The hydrosols at low concentration (10%) produced good inhibition against Candida albicans (57.45%), thus was deemed suitable for developing into a vaginal rinsing agent. Good inhibitions against tooth caries bacteria Streptococcus mutans and S. sorbrinus were also observed. After dilution 3-fold with water, the resistance values of S. mutans and S. sorbinus were 56.91% and 48.89%, respectively, and could be developed as a mouth rinse.
