By selecting the safest variety of cinnamon oil, you can significantly protect your health. Ceylon cinnamon oil is far safer because it contains less than 0.04 percent coumarin. Cassia varieties contain as much as 5 percent coumarin, which poses a risk to the liver. By becoming familiar with the botanical sources of the oil used and checking the labels before purchase, you can avoid many problems.

  • Contains less than 0.04% coumarin preventing liver strain
  • Suitable for occasional internal use when properly diluted

Identifying correctly will provide you with genuine Ceylon oil. Look for the botanical name on the label, Cinnamomum verum. Cassia is commonly referred to as Cinnamomum cassia or Cinnamomum aromaticum under the name cassia. Reputable dealers will provide GC/MS test reports that reveal the chemical constituents. Avoid products with vague or uncertain source information.

Special populations benefit the most by choosing Ceylon. Pregnant women should only use Ceylon wherever called for. Children over six can tolerate it in extremely dilute solutions. Those with liver conditions should avoid unnecessary coumarin exposure. Always consult your healthcare provider if you have any doubts about usage.

Storage methods retain the salutary properties of Ceylon oil. It is to be stored in dark glass bottles at a temperature below 77°F. The different grades should never be mixed in the same container. The packages should clearly display the botanical name of the product and the expiration date. If properly cared for, it will maintain its medicinal properties for a period of two years.
