Infuse a small piece of crushed bark in hot water for about ten minutes, covered. This preparation was traditionally taken after meals. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
In Chinese pharmacopoeia, the bark was decocted with other plants according to precise formulas, under the supervision of a trained practitioner. This preparation should not be improvised alone, due to the coumarin content. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
Dried leaves, less concentrated in coumarin than bark, were sometimes infused for occasional and light use, for aromatic and digestive purposes. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
Dried Chinese cinnamon bark and leaves can be found at specialized herbalists and Asian grocery stores; the tree itself grows primarily in the warm and humid regions of southern China and Vietnam.
The bark is traditionally harvested in late spring or summer, when the sap flows abundantly, which facilitates its detachment from the trunk.
