Cinnamomum cassia

Slightly more tapered than true cinnamon bark, cassia is warm, sweet and offers a similar profile to highly revered cinnamon bark. This CO2 extract is top notch!

Dr. Nick Notes

Similar to true ceylon cinnamon from Sri-Lanka, Cassia assists in clearing toxins and infections from the body, particularly the kidneys and colon. Reducing gas in the digestive system. Potent fighter of fungal infections – ringworm and candida and general colds and viruses. It has been shown to counter bacteria responsible for food poisoning. It's ability in destroying free radicals makes it a wonderful antioxidant. With a wonderful warm and inviting aroma, who wouldn’t want to sit and relax? Cassia also has a known reputation as an aphrodisiac, likely as cassia warms the body ~ my intuition predicts vasodilatory properties – if used in this way, would want to use <0.5-1% as an anointing oil infused into a carrier oil.

Although Cassia is Generally Recognized as Safe (GRAS) by the Food and Drug Administration (FDA) its main constituent is cinnamaldehyde which is not recommended for topical use on the skin. There's some evidence suggesting cinnamon bark may be used as a blood glucose lowering agent – cassia likely has similar properties with it's close chemical relationship. Be aware if taking other medication that lower blood sugar. Avoid cassia internally during pregnancy.

Note: It’s recommended not to use in foods or ingested unless diluted – cassia is a strong dermal irritant and may irritate the oral mucosa. Sensitive individuals should not cook or flavor with this oil and ALWAYS dilute the oil before ingestion.

How to Use

– Diffuse 1-5 drops into a diffuser to warm & uplift an environment.
– Not recommended for topical use.
– Cassia may be used in up to 5 drops internally daily. Use in a capsule infused into edible carrier oil OR may dilute appropriately in foods (great for chai, apples, chocolate!) Not to exceed 200 mg each day internally.
– Try diluting 1 drop in 2 tsp honey or 8 oz. of liquid – stir well!

For internal use with a trained practitioner or under a physician’s care ONLY. Must DILUTE before oral ingestion.

** Please note that this Cassia extract is grown under conventional farming techniques and does not have organic certifications. If used internally, do so at your own discretion (it is delicious, I enjoy this extract) **

Each distillation & plant source varies and current batch will likely have some variance to the information published above. When possible, we will post current GC-MS analysis separately for our oils sold on this site, correlating with batch numbers for your enjoyment & awareness.
