True Cinnamon or Cassia Cinnamon?

Why You Should Purchase True Cinnamon v Cassia

Cinnamon is one of the world’s oldest spices. It was used throughout the ancient world, with Egyptians using it as a perfuming agent during embalmment and when Emperor Nero’s second wife died, he burned as much of the spice as he could obtain, on her funeral pyre, to atone for his part in her death.

It is important to realise that not all cinnamon is equal and that they can have different impacts on our health.

True Cinnamon

Lucy Bee Cinnamon is cinnamon zeylanicum, also known as ‘true cinnamon’ which is the one that has been linked to having health benefits. It is naturally high in:

  • calcium, which contributes to the normal function of digestive enzymes
  • iron, which contributes to normal energy-yielding metabolism and to the reduction in tiredness and fatigue
  • manganese, which contributes to the protection of cells from oxidative stress

In our quest to offer natural and premium quality ingredients, you won't be surprised to know that our Cinnamon Powder is  also organic and Fair Trade.

Cassia Cinnamon

The other type of cinnamon which is frequently distributed by shops, is not ‘true cinnamon’ but Cassia cinnamon, which is also known as Chinese cinnamon. Its scientific name is Cinnamomum Aromaticum.


Ceylon and Cassia cinnamons may have certain features in common but they have one major difference, which is the amount of coumarin they contain. So, what is coumarin and why should we be aware of the coumarin content of different cinnamons?

Well, coumarin is a natural flavouring and fragrant compound found within plants, however, it is toxic to our liver cells (Hepatotoxic) and potentially also has carcinogenic properties (can increase risk of cancer) when eaten in excess (Lake, 1999. Uehara et al., 2008).

Studies have found that humans are more susceptible to the hepatotoxic effects of coumarin than animals used within studies (Abraham et al., 2010). It has been found that the amount of coumarin absorbed from cassia cinnamon is only slightly lower than that when coumarin was isolated and given to healthy individuals (Abraham et al., 2011).

This lead to the European Food Safety Authority setting a Tolerable Daily Intake of coumarin to 0.1 milligrams per Kg of bodyweight per day.

This is believed to be the set amount which will not increase your risk of its negative effects (Food Standards Agency, 2015), in other words you can safely eat this amount each day. So if an adult weighed 55Kg, they would be able to safely consume 5.5 milligrams of coumarin every day without any impact on their health. It is especially important for those who are sensitive to coumarin not to exceed this intake.

Cassia cinnamon is often easily available in stores because it comes at a cheaper price than true cinnamon yet, Cassia, has high levels of coumarin and can contain up to 1% of coumarin (Blahová and Svobodová, 2012).

Studies have found a wide range of differing amounts of coumarin within different Cassia bark samples, with some having low levels and others containing around 10,000 milligrams/Kg. They even found that bark collected from the same tree could have a varied amount of coumarin (Woehrlin et al., 2010).

Whereas the bark which is used for true cinnamon has very low levels/traces of coumarin, around 0.004% (Wang et al., 2013).

It's this difference in levels of coumarin which affects the aroma of the cinnamon - true cinnamon, with it's low levels of coumarin, naturally has a lighter aroma than Cassia.


As with everything, it's good to know what you're eating. It is recommended that if you frequently use large quantities of cinnamon then a better option is to use true cinnamon rather than Cassia, due to the lower levels of coumarin in true cinnamon.

An excessive intake over your tolerable daily intake (e.g. 60Kg adult’s tolerable daily intake is: 6 milligrams of coumarin per day) of coumarin may lead to damage to the liver cells, which has a negative impact on health. Although this damage appears to be reversible it is not recommended to risk the health implications.

It is also a good idea to be aware of cinnamon-based food products which may also use Cassia cinnamon, due to its cheaper pricing.

If using true cinnamon, it is a great sugar free alternative to sugar to sweeten drinks. For example, our Lucy Bee Hot Chocolate with Cinnamon is a great alternative to hot chocolates which are sweetened with sugar, and is also low in coumarin.
