Cinnamomum zeylanicum, accepted today as Cinnamomum verum, is a small evergreen tree of the laurel family native to the wet lowlands of Sri Lanka and the Western Ghats of Kerala and Karnataka, where the bark of coppiced shoots is peeled, scraped and dried into thin fragrant quills. Ayurveda calls the bark Twak and uses it as a warming aromatic that kindles digestion, clears the throat and chest, and carries other herbs deeper into the tissues; with cardamom and Tamalapatra leaf it forms Trijataka, the trio sprinkled over countless decoctions and fermented preparations. True cinnamon is milder, sweeter and much lower in coumarin than the cassia bark that dominates the world spice trade.

In practice

The Ayurvedic physician uses Twak in small quantities and often in company. As a deepana pachana it goes with Shunthi, Ela and Pippali for weak, cold digestion; in Sitopaladi churna it warms and moves the cough of a kapha chest while sugar and Vamshalochana soothe it; in Trijataka it sweetens and warms the taste of bitter decoctions and helps them reach the tissues.

From the sources

Overview. Cinnamomum zeylanicum, accepted today as Cinnamomum verum, is a small evergreen tree of the laurel family native to the wet lowlands of Sri Lanka and the Western Ghats of Kerala and Karnataka, where the bark of coppiced shoots is peeled, scraped and dried into thin fragrant quills. Ayurveda calls the bark Twak and uses it as a warming aromatic that kindles digestion, clears the throat and chest, and carries other herbs deeper into the tissues; with cardamom and Tamalapatra leaf it forms Trijataka, the trio sprinkled over countless decoctions and fermented preparations. True cinnamon is milder, sweeter and much lower in coumarin than the cassia bark that dominates the world spice trade.

Overview. Cinnamon is the dried inner bark of a small evergreen tree native to Sri Lanka and southern India, long cultivated across South and Southeast Asia. The plant was originally grouped with the true laurels under the genus Laurus before being reclassified into its own genus within the Lauraceae. In the physiomedicalist tradition it was valued chiefly as a warming, relaxant-to-stimulant tonic for the digestive tract, used to counter coldness and atony of tissue rather than to treat acute inflammation.

Clinical Notes. Inner bark used TCM=will tonify kidney yang, dispel cold, warm the spleen, relieve pain & enhance movement of qi & yang, warm middle jiao, treat cold digestive disorders, dispel gas, infuse warmth, dispel blood stagnation, promote blood circulation

Clinical Notes. The Ayurvedic physician uses Twak in small quantities and often in company. As a deepana pachana it goes with Shunthi, Ela and Pippali for weak, cold digestion; in Sitopaladi churna it warms and moves the cough of a kapha chest while sugar and Vamshalochana soothe it; in Trijataka it sweetens and warms the taste of bitter decoctions and helps them reach the tissues.
