Cinnamon Oil Effect
Cassia oil has a strong bactericidal effect and is better than negative ones for rigid bacteria stained by gram. Because of its irritant, it is rarely used as an antibacterial agent, but external application can treat stomachache, gastrointestinal distension and colic.
Cinnamon oil can be used internally as stomach - toning and anti - wind agent. Also has the obvious fungicidal effect, once used to contain 1.5% cinnamon oil and 0.5% thymol mixture to treat tinea capitis.
