Cassia Cinnamon can allegedly thin your blood while Ceylon Cinnamon doe snot have this ability. While thinning blood can be useful for some medical conditions like heart disease, it can be problematic if you taking blood thinning medication at the same time. It is said that Cassia Cinnamon has properties that act like an anti clotting agent.


Most times heart rates can increase when you directly breath in Cinnamon essential oil. Undiluted Cinnamon essentials are extremely powerful. Avoid opening the bottle and breathing Cinnamon Oils directly if you have a heart condition. Diluted and used in an aroma diffuser it should still be fine. But there is still a chance your heart rate could increase if you especially sensitive to Cinnamon oils. You can possibly get increased heart rates even after consuming Cinnamon powder or Cinnamon sticks. Saigon Cinnamon for example has high levels of essential oils in them so it is possible you might get an increased rate from Saigon Cinnamon. More so than other types of cinnamon.



Pregnant women should not take Cinnamon. This is because Cinnamon (especially the oils) can induce premature labor or uterine contractions. While Cinnamon helps with stomach pains, gas of indigestion, you should NOT be taking Cinnamon for these purposes while you are pregnant. Better safe than sorry. An occasional cup of Cinnamon is probably safe but why take a chance? Taking Cinnamon tablets or especially smelling Cinnamon Oil should be avoided at all costs.



If you touch Cinnamon oil without diluting it, it will irritate your skin and create a burning sensation. Kind of like chili powder. This is particularly acute if you touch any genitalia after handling pure Cinnamon oil. So it's best to wear gloves or be careful not to spill any on your hands.


As with most things taking Cinnamon over extended periods of time will build a certain level of toxicity in your body. The recommended dosage of Cinnamon according to the US Department of health, is 6 grams daily for 6 weeks or less. At this level of Cinnamon appears to be safe for most people. We recommend you follow these directions with a week of rest from Cinnamon every 6 weeks. This will allow any toxicity to be purged from your system. Or you could try 5 days and 2 days of rest from Cinnamon on the weekends.


Cinnamon can often cause conflict with medication especailly diabetes medication. This is because Ceylon Cinnamon especially the Bark Oil can also dramtically reduce blood sugar levels.


Cinnamon is spice that increases heat in your body. Both when applied topically and when taken internally. This is especially noticeable if you apply some Cinnamon essential oil to your skin. It will burn your skin. Which is why it must be diluted to 1% when applied topically.

Body heat can increase even if you take Cinnamon powder form or adding a Cinnamon stick to a stew or other food recipes. Taking it occasionally is not going to make much difference. And during winter time some added in Cinnamon in your daily diet is likely to keep your bones during those bone chilling winter days.

Increase body heat can manifest itself in many forms. As body increases your body will try to vent out this excess heat in different forms. The common way is for you to get boils under your tongue, rash, swelling, cracked lips, cracked heels and the like. If you going through Menopause for example avoid Cinnamon as increased body heat and menopause is not a good combination.

If you taking Cinnamon on a daily basis, then balance it out with a cooling food. The Chinese for example always balance warming food with cooling food. Examples of cooling foods are cucumber, yoghurt, apples, celery. Take a look here for example of both cooling and warming food.
