Introduction:

Clove , also known as Caryophyllum, Clove flower, or Clove buds, is a versatile and aromatic herb that has found its way into culinary and medicinal realms. This article will take you through the fascinating world of cloves, exploring their biological source, chemical constituents, uses, and much more.

Biological Source:

Clove origanates from the dried flower buds of the Eugenia caryophyllus plant, belonging to the Myrtaceae family. These buds should contain a minimum of 7.0 per cent (w/w) of eugenol when calculated on a dried basis.

When examining cloves visually, you’ll notice several distinctive features:

Colour: Cloves exhibit hues ranging from crimson to dark brown.

Odour: They possess a slightly aromatic fragrance.

Taste: Cloves are characterized by their pungent and aromatic flavour, followed by a tingling numbness.

Size: Typically, cloves measure around 4 mm in width, 10 to 17.5 mm in length, and 2 mm in thickness.

Shape: The hypanthium is crowned with four thick, acute, divergent sepals encircled by a dome-shaped corolla. The corolla comprises unexpanded membranous petals with several stamens and a single prominent style.

Chemical Constituents:

The composition of cloves varies depending on factors like agroclimatic conditions, growth, processing, and storage.

Cloves contain carbohydrates, fixed oil, steam-volatile oil, resins, tannins, proteins, cellulose, pentosans, and mineral elements. Carbohydrates make up about two-thirds of the spice’s weight.

They are an excellent source of vitamin K, vitamin C, dietary fibre, manganese, omega-3 fatty acids, and calcium and magnesium.

Clove boasts a rich chemical composition, including:

  • Volatile oil (approximately 15 to 20 percent)
  • Tannin (gallotannic acid) (10 to 13 percent)
  • Resin
  • Chromone
  • Eugenin

The volatile oil contains eugenol (70 to 90 per cent), eugenol acetate, Caryophyllenes, and small quantities of esters, ketones, and alcohols. Clove oil is colourless to pale yellow but thickens and darkens with storage.

Uses:

Clove plays numerous roles:

Dental Analgesic: It helps alleviate toothache and oral discomfort.

Carminative: Clove aids in reducing gas and bloating.

Stimulant: It can stimulate various bodily functions.

Flavouring Agent: Clove enhances the flavour of food and beverages.

Aromatic: Its aromatic properties make it valuable in perfumery.

Antiseptic: Clove is renowned for its antiseptic qualities.

Perfumery: Clove oil is also used in perfumery and is employed in manufacturing vanillin. It finds its place in the preparation of cigarettes.

Adulterants:

Several adulterants have been identified:

Mother Cloves: These are dark brown, ovate-ripened fruits of the clove tree with slightly aromatic properties but containing starch. They have lower volatile oil content.

Blown Cloves: These are expanded flowers of the clove tree, often with detached stamens, resembling cloves but with lower volatile oil content.

Clove Stalks: These are used to adulterate powdered cloves and can be detected by the presence of isodiametric sclereids and prisms of calcium oxalate.

Exhausted Cloves: These are cloves from which oil has been extracted through distillation. They appear dark and shrunken and lack the presence of oil.

Medicinal and Pharmacological Uses:

Clove has been used in traditional Ayurveda to treat respiratory and digestive ailments.

Its properties include being spicy, warming, stimulant, analgesic, anaesthetic (topical), antiemetic, anti-griping (when combined with other herbs), vermifuge, uterine stimulant, antibacterial, antifungal, antispasmodic, stomachic, aromatic, carminative, antiseptic, antiviral, expectorant, aphrodisiac, and promoter of salivation and digestive juices.

In traditional Chinese medicine, cloves are employed as a kidney tonic for warming the body, increasing circulation, and aiding digestion.

They are also used for various conditions such as nausea, vomiting, flatulence, hiccups, etc.

Ethanolic Extract and Aphrodisiac Activity:

Ethanolic extract of clove has been shown to increase the sexual activity of male rats without notable adverse effects. This supports traditional claims of its usage in treating sexual disorders.
