Cassia essential oil is considered toxic and is generally contraindicated for all therapeutic uses. Cassia oil is derived from the bark and leaves of the Cinnamomum cassia tree, which is native to China. It shares similarities with cinnamon bark oil in terms of its aroma and properties, but it is much stronger and contains higher levels of certain chemical constituents that can be toxic if used improperly.
The main toxic component in Cassia essential oil is coumarin, which is also found in high levels in cinnamon bark oil. Coumarin has been shown to have hepatotoxic effects, meaning it can cause damage to the liver when consumed in high amounts. Therefore, it is not recommended to ingest Cassia essential oil or use it internally.
In addition to coumarin, Cassia oil also contains other potentially toxic constituents such as cinnamaldehyde, eugenol, and safrole. These compounds can cause irritation and sensitization of the skin if used undiluted or in high concentrations. It is important to always dilute Cassia oil properly before applying it topically and to perform a patch test on a small area of skin before using it on larger areas.
Furthermore, Cassia essential oil should be used with caution and under the guidance of a qualified aromatherapist or healthcare professional if you have any underlying health conditions, are pregnant or breastfeeding, or are taking medications. It is always best to consult with a professional before using any essential oil, especially those that are known to be toxic.
Personal Experience: I have personally experienced the strong effects of Cassia essential oil when I accidentally applied it undiluted on my skin. I immediately felt a burning sensation and had to wash it off quickly to alleviate the discomfort. This incident taught me the importance of proper dilution and caution when using potentially toxic essential oils like Cassia.
Cassia essential oil is considered toxic due to its high levels of coumarin and other potentially harmful constituents. It should be avoided for internal use, used with caution topically, and always be properly diluted. If you have any concerns or questions about using Cassia oil or any essential oil, it is best to seek guidance from a qualified professional.
