Cinnamon

The part of the tree used is the bark of its tender branches. It contains essential oils with cinnamaldehyde and eugenol ^{(Fitoterapia.net, WHO 1999 p95)}.

Precautions when taking plant preparations ^{(Anderson 2017, Powers 2015, Posadzki 2013, Efferth 2011, Kopec 1999)}:

• Make sure they are from a reliable source. Poisonings have occurred due to confusion of one plant with another with toxic properties ^{(Hsu 1995)}, poisonings due to containing heavy metals extracted from the soil and food poisoning due to contamination with bacteria or fungi.
• Do not take in excess. Follow the recommendations of professional experts in herbal medicine. “Natural” products are not good in any quantity: plants contain active substances from which a large part of our traditional pharmacopoeia has been obtained and can cause poisoning or act as endocrine disruptors if they are consumed in an exaggerated quantity or time, because they contain phytoestrogens. ^{(Powers 2015, Zava 1998)}
