In Practice:

  • One of the very few warming demulcents in the Western materia medica, cinnamon is favored for cold, dry constitutions, helpful for cold, dry digestive problems and nervous system complaints.
  • Cinnamon scent is very comforting, especially with rose, because the scents of these plants can often bring on feelings of love and safety.
  • Cinnamomum verum and Cinnamomun cassia have somewhat different flavors and actions: C. verum is sweeter and less astringent, with greater diaphoretic activity; cassia has greater documented capacity for lowering blood sugar levels.

Rate of Use: No more than 2g a day.
 Cinnamon effects blood glucose, diabetics taking Glucophage (Metforman) or using insulin injections need to monitor their blood glucose levels. C. cassia has a blood thinning effect and contains higher levels of coumarin and those with existing liver conditions should avoid large doses (2g or more a day). Cinnamon’s mucilage causes it to congeal if infused in wine or other low-alcohol menstruum and this may harbor mold. Take caution when inhaling the powder as it can cause coughing. As a mild emmenagogue caution has been recommended in the early stages of pregnancy, but there are no known cases of a miscarriage resulting from cinnamon use.
