Cinnamomum zeylanicum (Cinnamomum verum) - Cinnamon bark, Ceylon cinnamon
"CONSTITUENTS: Volatile oil, tannin, sugar, mannit, starch mucilage.
PREPARATIONS: Tinctura cinnamomi, tincture of cinnamon. Dose: from a half to two drams. Specific cinnamon. Dose: from ten to thirty Minims.
Therapy: Cinnamon, in the experience of the writer, is a hemostatic of much power and is positively reliable in all passive hemorrhages. It is not advisable to combine it with the usual astringents, as ergot, geranium or epilobium, but it acts in perfect harmony with erigeron and to a certain extent with turpentine. German authorities claim that as soon as the menses or any uterine hemorrhage becomes excessive and produces exhaustion or causes alarm the decoction should be administered freely. It works to a better advantage in hemorrhage due to atonic conditions of the non-gravid womb, or where there is muscular relaxation, or a general flaccid state of the womb after delivery.
It certainly restores tone to the uterine muscular structure and induces tonic contraction. It will also, Hale says, moderate hemorrhage not dependent on plethora, anemia or organic uterine disease. In some cases, during labor, it promotes the normal labor pains and materially increases uterine contraction, and prevents post-partum hemorrhage. ..."
