A metal, several salts of which are used in medicine for external application. It is essential for growth and development in animals and plants. The average human body contains a total of 1– 2 grams, and most human diets contain 10–15 mg. In human beings, de?ciency of zinc results in lack of growth, slow sexual development and ANAEMIA. De?ciency is also associated with a skin disorder known as acrodermatitis enteropathica.

Uses Zinc chloride is a powerful caustic and astringent which, combined with zinc sulphate, is used as an astringent mouthwash. Zinc sulphate is also used in the form of eyedrops in the treatment of certain forms of conjunctivitis (see under EYE, DISORDERS OF).

Zinc oxide, zinc stearate, and zinc carbonate are made up in dusting powders, in ointments, in paste bandages or suspended in water as lotions for the astringent action they exert upon abraded surfaces of the skin. Zinc and castor oil ointment of the British Pharmacopoeia is a well-tried treatment for nappy rash.

The Ayurvedic Pharmacopoeia ofIn- dia indicated the use of dried mature leaves of Cinnamomum tamala and dried inner bark of C. zeylanicum in sinusitis.

Cinnamaldehyde is the major constituent (74%) of the essential oil from bark.

Major constituent of the leaf oil is eugenol (28-98%) and that of root- bark oil camphor (60%).

Cinnamaldehyde is hypotensive, spasmolytic and increases peripheral blood flow; and it inhibits cyclooxy- genase and lipoxygenase enzymes of arachidonic acid metabolism.

Cinnamaldehyde exhibits CNS stimulant effects at high doses. (Natural Medicines Comprehensive Database, 2007.)

The bark oil and extracts exhibit antibacterial, antifungal and antiviral activities, and enhance trypsin activity.

Eugenol content of the leaf oil is antiseptic and anaesthetic. It is not inter- changable with the bark oil.

Root bark oil acts as a stimulant in amenorrhoea. The bark contains tannins (6.5%) consisting of tetrahydrox- yflavandiols; diterpenes, cinnzeylanin and cinnzeylanol.

Unani: Zarambaad. Siddha/Tamil: Kichhilikkizhangu.

Action: Carminative, stomaehie, gastrointestinal stimulant, diuretic, expectorant, demulcent, rubefacient. Used in flatulence and dyspepsia. Fresh root is used for checking lecorrhoeal discharge; also for blood purification. Zedoary's effect on digestive organs is similar to ginger but milder.

Along with other therapeutic applications, The Ayurvedic Pharmacopoeia of India indicated the use of the rhizome in goiter.

The rhizomes are a source of Shoti Starch, used as a food for babies and convalescents, recovering from chronic stomatitis. It is cooling and demulcent.

Zedoary, dried rhizomes, contains a number of terpenoids, including curcumene, curcumenone, curdione, curcumenol. Curzerenone, furanoger- menone, germacrone, germacrone epoxide; a volatile oil (1.0-1.5%) resembling ginger oil, and starch (50%).

Zedoary is thought to stimulate bile production (due to sesquiterpene ke- tones) and gall bladder emptying (due to cucuminoid constituents).

The sesquiterpenes, germacrone, germacrone epoxide, curzerenone and curcumenol showed CNS depressant properties. Curzerenone also showed a potent protective effect against induced lesions in rats. Both curz- erenone and curcumenol showed a moderate analgesic action.

The terpenoid furanogermenone exhibits antiallergic activity. (Powdered zedoary, mixed with fructose, is used as an antiallergant in Japan.)

Curcumenol and curdione are shown to possess tumour-inhibiting property. The rhizome is used in China for extradural haematomas and certain types of tumours. It has been reported in China that zedoary reduced cervical cancer and increased the effects of chemotherapy and radiotherapy.

The volatile oil of zedoary exhibits antimicrobial and antifungal activity. The antifungal constituent of the oil has been reported as methyl-p-methoxy- cinnamate.

The chloroform extract of the root showed significant activity against pencillin-resistant (also non-pencillin resistant) strains of Neisseria gonorrhoea. (The root is used for treating sexually transmitted diseases in traditional Indian medicine.)

In Siddha medicine, in Tamil Nadu, the plant is an ingredient in a number of drug formulations for treating cancers of the uterus, breast, lungs and oral cavity, in addition to haemorrhoids.

Habitat: Wild throughout India, also cultivated in tropical parts of India.

English: Cassumunar Ginger.

Ayurvedic: Vanardraka, Peja, Peyu, Aardikaa, Shringaberikaa.

Folk: Adarakhi, Bana-adarakhi.

Action: Rhizome—carminative, stimulant, antispasmodic. Used for diarrhoea and colic.

The occurance of an active diastase in the rhizome has been reported.

The enzyme resembles in its activity with alpha-amylase of Aspergillus oryzae. The rhizome gave an essential oil consisting of terpinen-4-ol (about 35%); other constituents are alpha- and beta-pinene, sabinene, myrcene, terpinene, limonene, p-cymene and terpinolene. The fresh rhizomes contain phenyl butenoic dimers, along with cyclohexane derivatives. Hex- ane extract of the rhizome contained (E)-4-(3'4'-dimethoxyphenyl)-but-3- en-l-ol, known as compound D. Compound D showed antispasmodic effect on guinea-pig ileum and tracheal smooth muscle, also a dose-related uterine relaxant effect in situ in non- pregnant rats; in pregnant rats the response varied with the period of pregnancy. Aqueous extract of the rhizome showed smooth muscle relaxant and anti-inflammatory activity Antioxi- dant activity was found to be more intense than that of known curcum- inoid antioxidants. It is attributed to cassumunin A.... zingiber cassumunar

Family: Zingiberaceae.

Habitat: Native to Southeast Asia; now cultivated mainly in Kerala, Andhra Pradesh, Uttar Pradesh, West Bengal, Maharashtra.

English: Ginger.

Ayurvedic: Fresh rhizome— Aardraka, Aadrikaa, Shrngibera, shrngavera, Katubhadra. Dried rhi- zome—Shunthi, Naagara, Naagaraa, Naagaraka, Aushadha, Mahaushad- ha, Vishvaa, Vishvabheshaja, Vishvaaushadha.

Unani: Fresh rhizome—Zanjabeel- e-Ratab, Al-Zanjabeel. Dried rhizome—zanjabeel, Zanjabeel-e- yaabis.

Siddha: Fresh rhizome—Inji, Allam, Lokottai. Dried rhizome— chukku, Sunthi.

Action: Rhizome—antiemetic, antiflatulent, hypocholesterolaemic, anti-inflammatory, antispasmodic, expectorant, circulatory stimulant, diaphoretic, increases bioavailabil- ity of prescription drugs. Used for irritable bowel and diarrhoea, colds and influenza. Showed encouraging results in migraine and cluster headache (J Ethnophar- macol, 1990, 29, 267-273; Aust J Med Herbalism, 1995, 7/3, 6978; Natural Medicines Comprehensive Database, 2007.) The Ayurvedic Pharmacopoeia of India recommends dried rhizomes in dyspepsia, loss of appetite, tympanitis, anaemia, rheumatism, cough and dyspnoea; fresh rhizomes in constipation, colic, oedema and throat infections.

Key application: For dyspepsia and prevention of motion sickness (German Commission E); vomiting of pregnancy, anorexia, bronchitis and rheumatic complaints (The British Herbal Compendium); as a post-operative antiemetic. (ESCOP).

The rhizome contains an essential oil containing monoterpenes, mainly geranial and neral; and sesquiterpenes, mainly beta-sesquiphellandrene, beta- bisabolene, ar-curcumene and alpha- zingiberene; pungent principles, consisting of gingerols, shogaols and related phenolic ketone derivatives. Other constituents include diarylheptenones, diterpenes, gingesulphonic acid and monoacyldigalactosyl glycerols.

Gingerol and shogaol have been shown to suppress gastric contractions. Both fresh and dried rhizomes suppress gastric secretion and reduce vomiting. Gingerol and shogaol have gained importance due to their sedative, anti-inflammatory, antipyretic, analgesic, hypotensive and hepatopro- tective activities.

Cardiotonic effects of ginger has been attributed to 6-and 8-shagaols and gingerols. (Antithrombotic effects remain unconfirmed.) Antimigraine effect is due to ginger's ability to decrease platelet aggregation. It also acts as a potent inhibitor of prostaglandins which enhance release of substance P from trigeminal fibers. (PDR, 2004.)

Indian ginger is considered only second to Jamaican in quality.

There are three main types of Indian ginger—Cochin ginger (light brown or yellowish grey; Calicut ginger from Malabar (orange or reddish brown, resembling African ginger) and Kolkata ginger (greyish brown to greyish blue).... zingiber officinale

Zerumbone inhibits the growth of Micrococcus pyogenes var. aureus and Mycobacterium tuberculosis.
