(German Commission E, The British Herbal Pharmacopoeia, ESCOP.)The bark yields an essential oil containing cinnamaldehyde (82.2%) and eugenol (1.5%) as major constituents.Cinnamaldehyde is a weak CNS stimulant at low doses and a depressant at high doses and has spasmolytic activity. It is hypotensive, hypogly- caemic and increases peripheral blood flow; it reduces platelet aggregability by inhibiting both cyclooxygenase and lipoxygenase pathways of arachidonic acid metabolism.Aqueous extract of the bark shows significant antiallergic activity in guinea pig. Diterpenes (Cinncassi- ols) are thought to be responsible for atleast some of the antiallergic effects.The herb inhibited ulcers induced by ethanol, also ulcers induced by phenylbutazone; failed to prevent ulcers induced by indomethacin. (Planta Med 1989, 55(3), 245-248.)The extract, when administered orally to rats with nephritis, prevents the increase of protein level in urine.The bark markedly reduces blood pressure in experimental rats; exhibits tranquilizing effect and is used as an antiepileptic and sedative agent in drugs ofTCM.
