Even though there is a popular belief that cinnamon tea can induce late period, there is no scientific evidence that proves this.  

Studies carried out so far show that cinnamon tea prepared with the Cinnamomum zeylanicum species, which is the most consumed species in the world, is efficient in alleviating menstrual cramps and reducing menstrual flow. However, there is no evidence that it provokes uterine contractions and the onset of menstruation. 

As for adverse effects, what is known is that overdosage of cinnamon is bad for the liver, especially if the essential oil is the source of the overdosage. Additionally, other types of cinnamon in the form of essential oils may lead to changes in the uterus with the risk of causing a miscarriage. However, this only happens when there is an overdosage of the essential oil and up to now, this effect has only been observed in animals.

How cinnamon affects the menstrual cycle

Even though there is a popular belief that cinnamon tea helps to regulate a late period when taken regularly, there is no scientific evidence that demonstrates the real impact of cinnamon on the functioning of the menstrual cycle.

The only link that seems to exist between cinnamon and the menstrual cycle, according to some studies, is that cinnamon tea seems to help reduce menstrual discomfort. This is because it is capable of reducing prostaglandin levels, increasing endorphin levels, and improving blood circulation. Therefore, it is effective in relieving PMT symptoms, especially menstrual cramps. 

Additionally, it was observed that consuming the right quantity of cinnamon tea (as recommended by a herbal practitioner or naturopath) has a relaxing effect and decreases uterine contractions in those with dysmenorrhea and it prevents contractions during pregnancy. It also helps decrease menstrual flow in women who have heavy periods.

Can I take cinnamon tea while pregnant?

Up to now, no side effects have been verified in pregnant women who consume cinnamon tea made with  Cinnamomum zeylanicum. However, when the tea is made with Cinnamomum camphora, there may be bleeding, and changes to the uterus. Additionally, in a study carried out on mice, it was observed that cinnamon essential oil can cause miscarriages. However, the effect on mice may not be the same as on people, so further studies are necessary in order to prove that cinnamon essential oil really can cause miscarriages in humans.

Due to the fact that there are no scientific studies that indicate the possible consequences of the consumption of cinnamon tea in pregnancy, the recommendation is that pregnant women do not consume cinnamon tea in order to avoid complications. 

How to make cinnamon tea

Cinnamon tea is easy and quick to prepare and it is great for improving digestion and general well-being, and decreasing fatigue due to its properties. In order to prepare the tea you need: 


  • 1 cinnamon stick;
  • 1 cup of water.

How to prepare the tea

Place the cinnamon stick in a pan with water and let it boil for five minutes. After this, leave it to cool down, take the cinnamon out and drink the mixture. If you wish, you can sweeten the tea to your liking.

Even though there is no scientific evidence that cinnamon can help the onset of menstruation, it is used a lot for that purpose. However, if you would like to induce menstruation, you can take teas that are proven to encourage changes in the uterus and that can speed up menstruation, such as ginger tea.
