Scientific Name: Cinnamonum zeylanicum/verum
Constituents:
- Volatile oil (cinnamaldehyde, eugenol, and methyleugenol & linalool)
- Flavonoids: Methylhydroxychalcone polymers
- Tannins
- Coumarins
Medicinal actions:
- Antimicrobial
- Antioxidant
- Astringent
- Carminative & Antispasmodic
- Hemostatic
- Hypoglycemic
Mechanism of Action & Pharmacology:
- Volatile oils are antispasmodic, anti-bacterial, anti-fungal, & anti-viral.
- Cinnamaldehyde inhibits cyclooxygenase & lipoxygenase enzymes, thus decreasing inflammation. Also expresses insulinotropic effects on blood glucose by up-regulating GLUT4 gene expression & glycoprotein movement from intracellular compartments to facilitate glucose entrance into the cells.
- Methyl hydroxychalcone is a flavonoid responsible for the insulin-like biological activity.
- Tannins are highly astringent.
Pharmacy:
- Decoction
- Tincture
- Capsules
- As Food in culinary applications
