Coumarin, oh coumarin
Aug 9, 2018
As
with any food consumption, if one overdoses on something, it is not healthy.
Moderation is the key in cinnamon consumption.
Coumarin is
a natural compound that occurs in celery, chamomile and green tea. It has anti-coagulant and anti-inflammatory
properties. In small quantities, it has high medicinal values. It is only toxic if taken consistently in high quantities, such as several tablespoons of cinnamon powder
daily for several months. When you make teas, health infusions or use
cinnamon as a spice in cooking and
baking, the amount of coumarin you consume is small, even if it is from Cassia
cinnamon.
Are we so scared about coumarin that we don’t
eat celery or drink green tea any more?
Drinking
teas made from cinnamon several times a week is very different from consuming
three tablespoons of cinnamon powder
daily.
If you are concerned about coumarin in
cinnamon:
i. Do
not take it as a food supplement such as powder in pill form unless you have a
doctor’s prescription.
ii. Avoid daily cinnamon powder intake if you are pregnant or sensitive to coumarin. Consult your doctor especially when you are taking other medications.
iii. If you still want to take cinnamon in powder form --
The tolerable daily intake of coumarin is 0.1mg/kg of body weight. For a 50kg person, that's 5mg.
1 teaspoon of ground cinnamon is 1.5gm. Cassia Cinnamon contains approx. 1% of coumarin. Hence 1 flat teaspoon would have 0.015gm or 15mg of coumarin in Bario cinnamon powder.
To bring that to a tolerable range, take less than 1/3 flat teaspoon a day, or put 1/10 flat teaspoon of cinnamon powder into your drink per day.
