Medicinal properties of Indian Bay leaf:

Part used- Leaf, Bark, Oil
Dosage-
Bark powder- 1 to 3 g

Leaf powder- 1 to 3 g
Oil- 2 to 5 drops

Chemical composition:
The oil from bark contains cinnamaldehyde (70–85%) as major constituent. Leaves from Nepal yield a volatile oil, containing mainly linalool 54.55%; cinnamaldehyde 1.45%, alpha-and beta-pinene, p- cymene and limonene. In essential oil from the leaves, mostly monoterpenoides were found. Linalool [50%] is a major compound.α-pinene, p- cymene and limonene range around 5 – 10% each. Phenylepropanides appear in little amount.

Research articles related to Cinnamomum tamala:


Anti- ulcer activity: The present study was designed to study the antiulcer potential of 50% ethanolic extract of Cinnamomum tamala (EECT) on experimentally induced ulcer models like pylorus ligation, ethanol, and aspirin. The results of te present investigation reveal that in all three models studied, EECT (50,100 and 200 mg/kg,p.o) produced a dose-dependent significant protection against ulcer models in animals.  The results indicated that ethanolic extract of Cinnamomum tamala shows significant antiulcer activity by inhibiting the gastric lesions and provides the significant gastroprotective effect which may be associated with its antioxidant property.

Anti- microbial activity: In the present study phytochemical constituents, elemental composition and antimicrobial potential of the crude methanolic extract of Cinnamomum tamala leaves were explored. Antimicrobial potential of the crude extract and its fractions i.e. aqueous, n-hexane, dichloromethane and isobutanol were tested against six gram-negative, three gram-positive bacterial strains and one fungal strain by agar well diffusion method. The evaluated extracts evaluated showed variedable degree of inhibition zones against all tested microbes except dichloromethane, aqueous fraction and crude extract which were completely inactive against Salmonella typhi.

Anti- depressant activity: The current study was designed to explore anxiolytic, antidepressant, and antistress actions of Cinnamomum tamala (CT) leaves (aqueous extract) in rats. CT at 400 mg/kg produced an antianxiety effect equivalent to lorazepam, in the elevated plus maze, open field, and social interaction tests among selected doses of the CT. CT at 400 mg/kg also induced an antidepressant activity similar to imipramine, in the behavioral despair, learned helplessness test, and tail suspension among selected doses of the CT. Moreover, CT at 400 mg/kg produced a significant antistress effect comparable to W. somnifera in water immersion-restraint stress by decreasing ulcer index, adrenal gland weight, and by normalizing the plasma levels of corticosterone, glucose, cholesterol, and triglyceride levels when related to stress control.
