It's used to assist with bronchitis, diarrhoea, chills, infections, flu, rheumatism, and arthritis when used in bath water or blended into a massage oil. It eases nausea and vomiting. It stimulates the glandular system and therefore reduces menstrual pain. Avoid the  leaf oil during pregnancy.

The source of cinnamon was a mystery to the Western world for the longest time. According to Herodotus and other authors, Arabia was the source of cinnamon. The story goes that giant Cinnamon birds collected cinnamon sticks for their nests from a mysterious place where cinnamon trees grew. The Arabs then tricked the birds and got the cinnamon from them. This was the belief up to 1310 in Byzantium.
