Cinnamomum verum Presl (  syn  C.zeylanicum Bi) <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    Lauraceae Famiily. Its bark is used as condiment.


 A tree native  to <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Sri Lanka and    cultivated in South India for its aromatic bark and  also    found to a limited extent in eastern India.


. The bark is used to a limited extent in medicine. It is aromatic,    astringent, stimulant, expectorant and carminative. It possesses the    property of checking nausea and vomiting. As a stimulant it is    beneficial in cramps of the stomach, gastric irritation, and paralysis    of tongue. The ground cinnamon shows lipolytic activity. It is useful    in diarrhoea and dysentery. Externally the bark is used in neuralgia,    rheumatism and toothache. A decoction of the bark is reported to be    used for cancer of stomach, rectum and uterus.

     The oil is carminative and a powerful stimulant. The oil is also  a powerful germicide and an active fungicide. It is used as a

    cordial in cramps of the stomach, in syncope, in paralysis of the

    tongue and to deaden the nerve in toothache. Swallowed in excess, the    oil produces irritation of the gastro-intestinal tract which may    result in fatality. It is also used as an aromatic to mask the    disagreeable taste of other drugs.

The root bark  oil is used as a stimulant in    amenorrhoea. It is also antiseptic and is used in gonorrhoea. Locally    it is used as an application in neuralgia.


     The bark forms a component of the Unani durg `Majoon-e-flasfa' which    invigorates the muscular function of human body and acts as an    aphrodisiac. The drug is said to be useful in anorexia and disorders    such as arthritis, gout, lumbrgo and other rheumatic pains.

 Cinnzeylanin and cinnzeylanol show insecticidal activity    against larvae of silkworm (Bombyx mori ) and other insects.   The bark is reported to have shown mutagenic activity in rec -assay    in Bacillus subtilis  (Ehrenb.) Cohn strains H17 and M45. Thus it    may have associated carcinogenic action. The dried bark in the crude    form, its water-heated and water-macerated residues, and petroleum

    ether and chloroform extracts showed mutagenic activity, whereas    water-heated and water-macerated filtrates did not show the activity.    In another study petroleum ether and chloroform extract showed    cytotoxic effect on stable monolayer cell line from a human mouth    carcinoma and stable suspension cell line from a mouse lymphoid    leukemia.

The oil,    even in high dilution of 1:64 showed potent anti-bacterial activity    against several gram positive and gram negative bacteria such as    Micrococcus pyogenes  Lehmann&Neumann var. aureus  Hucker,    Bacillus subtilis  (Ehrenb.) Cohn, Salmonella typhi  (Schroter),    Enterococcus proteiformis  Thierc. & Jouh. and Lactobacillus    acidophillus  (Moro) Bergey

The essential oil, in    combination with other essential oils, was found to be effective    against Salmonella typhi , a human pathogen, and compared well with    the reference antibiotic, Chloramphenicol. The oil exhibited better    anti-microbial activity compared to some known anti- bacterial drugs    like Penicillin, Streptomycin and Tetracycline.

The oil at 1:64 dilution showed more anti-fungal activity than

    Griseofulvin (100 µg) against Aspergillus fumigatus  Fres., A.

      niger  van Tiegh., Candida tropicalis  (Cast.) Berkh.,

    Saccharomyces carlsbergensis  Lodder & Kreger-van Rij and Rhizopus    oryzae  Went. & Painsen Gearlings. The bark oil as well as chloroform    extract of the bark exhibited inhibitory activity against    aflatoxin-producing fungus Aspergillus parasiticus  Speae.

      The bark, either as small pieces or as powder, is extensively used as    spice or condiment. It is used for flavouring liquids such as hot    punches, spiced wines, soups and sauces. Powdered cinnamon is used in    cakes, biscuits, buns and puddings. It can be used in curries, tomato    ketchup and white sauces. It is also used as an adjunct to cordials    and stimulants.

      The emulsified cinnamon oil    enhances the keeping quality of fish at room temperature as well as on    refrigeration.
