Clove (Cengkeh)

Cloves (Syzygium aromaticum, syn. Eugenia aromaticum or Eugenia caryophyllata) are the aromatic dried flower buds of a tree in the family Myrtaceae. Cloves are native to Indonesia and used as a spice in cuisine all over the world. The English name derives from Latin clavus 'nail' (also origin of French clou 'nail') as the buds vaguely resemble small irregular nails in shape. Cloves are harvested primarily in Indonesia, Madagascar, Zanzibar, Pakistan, and Sri Lanka; it is also grown in India under the name Lavang .

The clove tree is an evergreen which grows to a height ranging from 10-20 m, having large oval leaves and crimson flowers in numerous groups of terminal clusters. The flower buds are at first of a pale color and gradually become green, after which they develop into a bright red, when they are ready for collecting. Cloves are harvested when 1.5-2 cm long, and consist of a long calyx, terminating in four spreading sepals, and four unopened petals which form a small ball in the centre.

Uses

According to FAO, Indonesia produced almost 80% of the world's clove output in 2005 followed at a distance by Madagascar and Tanzania.

Cloves can be used in cooking either whole or in a ground form, but as they are extremely strong, they are used sparingly. The spice is used throughout Europe and Asia and is smoked in a type of cigarettes locally known as kretek in Indonesia. The largest brand of kreteks in the United States is Djarum, who sells the iconic Djarum Black. Cloves are also an important incense material in Chinese and Japanese culture.

Cloves have historically been used in Indian cuisine (both North Indian and South Indian) as well as Mexican cuisine (best known as "clavos de olor"), where it is often paired together with cumin and cinnamon. In north Indian cuisine, it is used in almost all dishes, along with other spices. It is also a key ingredient in tea along with green cardamom. In south Indian cuisine, it is used extensively in biryani along with "cloves dish" (similar to pilaf, but with the addition of other spices), and it is normally added whole to enhance the presentation and flavor of the rice. In Vietnamese cuisine, cloves are often used to season pho broth.

Its essence is commonly used in the production of many perfumes.

During Christmas, it is a tradition in some European countries to make a pomander from cloves and oranges to hang around the house. This spreads a nice scent throughout the house and the oranges themselves act as Christmas decorations.

Medicinal and Nostrums

Cloves are used in Ayurveda called Lavang in India, Chinese medicine and western herbalism and dentistry where the essential oil is used as an anodyne (painkiller) for dental emergencies. Cloves are used as a carminative, to increase hydrochloric acid in the stomach and to improve peristalsis. Cloves are also said to be a natural antihelmintic. The essential oil is used in aromatherapy when stimulation and warming are needed, especially for digestive problems. Topical application over the stomach or abdomen are said to warm the digestive tract.

In Chinese medicine cloves or ding xiang are considered acrid, warm and aromatic, entering the kidney, spleen and stomach meridians, and are notable in their ability to warm the middle, direct stomach qi downward, to treat hiccough and to fortify the kidney yang. Because the herb is so warming it is contraindicated in any persons with fire symptoms and according to classical sources should not be used for anything except cold from yang deficiency. As such it is used in formulas for impotence or clear vaginal discharge from yang deficiency, for morning sickness together with ginseng and patchouli, or for vomiting and diarrhea due to spleen and stomach coldness. This would translate to hypochlorhydria. Clove oil is used in various skin disorders like acne, pimples etc. It is also used in severe burns, skin irritations and to reduce the sensitiveness of skin.

Ayurvedic herbalist K.P. Khalsa, RH (AHG), uses cloves internally as a tea and topically as an oil for hypotonic muscles, including for multiple sclerosis. This is also found in Tibetan medicine. Ayurvedic herbalist Alan Tilotson, RH (AHG) suggests avoiding more than occasional use of cloves internally in the presence of pitta inflammation such as is found in acute flares of autoimmune diseases.

In West Africa, the Yorubas use cloves infused in water as a treatment for stomach upsets, vomiting and diarrhoea.The infusion is called Ogun Jedi-jedi.

Western studies have supported the use of cloves and clove oil for dental pain, and to a lesser extent for fever reduction, as a mosquito repellent and to prevent premature ejaculation. Clove may reduce blood sugar levels.
