Ginger ( Zingiber officinale) is a flowering plant whose rhizome, ginger root or ginger, is widely used as a spice and a folk medicine. It is an herbaceous perennial that grows annual pseudostems (false stems made of the rolled bases of leaves) about one meter tall, bearing narrow leaf blades. The bear flowers having pale yellow petals with purple edges, and arise directly from the rhizome on separate shoots.
Ginger is in the family Zingiberaceae, which also includes turmeric ( Curcuma longa), cardamom ( Elettaria cardamomum), and galangal. Ginger originated in Maritime Southeast Asia and was likely domesticated first by the Austronesian peoples. It was transported with them throughout the Indo-Pacific during the Austronesian expansion ( Before Present), reaching as far as Hawaii. Ginger is one of the first spices to have been exported from Asia, arriving in Europe with the spice trade, and was used by ancient Greeks and Ancient Rome. The distantly related dicots in the genus Asarum are commonly called wild ginger because of their similar taste.
Ginger has been used in traditional medicine in China, India and Japan for centuries, and as a modern dietary supplement. Ginger may offer benefits over placebo for nausea and vomiting during pregnancy, but there is no good evidence that it helps with nausea during chemotherapy. It remains uncertain whether ginger is effective for treating any disease. In 2023, world production of ginger was 4.9 million , led by India with 45% of the total.
Ginger was carried with them in their voyages as during the Austronesian expansion, starting from around 5,000 Before Present. They introduced it to the in prehistory, long before any contact with other civilizations. Reflexes of the Proto-Malayo-Polynesian word *laqia are found in Austronesian languages all the way to Hawaii. They also presumably introduced it to India along with other Southeast Asian food plants and Outrigger canoe, during early contact by Austronesian sailors with the Dravidian-speaking peoples of Sri Lanka and South India at around 3,500 Before Present.
From India, it was carried by traders into the Middle East and the Mediterranean by around the 1st century CE. It was primarily grown in southern India and the Greater Sunda Islands during the spice trade, along with peppers, , and numerous other spices.
Ginger spice was introduced to the Mediterranean by the Arabs, and described by writers like Dioscorides (40–90) and Pliny the Elder (24–79). In 150, Ptolemy noted that ginger was produced in Ceylon (Sri Lanka). Ginger—along with its relative, galangal—was imported into the Roman Empire as part of very expensive herbal remedies that only the wealthy could afford, e.g. for the kidneys. Aëtius of Amida describes both ginger and galangal as ingredients in his complex herbal prescriptions.
Archaeological evidence of ginger in northwest Europe comes from the wreck of the Danish-Norwegian flagship, Gribshunden. The ship sank off the southern coast of Sweden in the summer of 1495 while conveying King Hans to a summit with the Swedish Council. Among the luxuries carried on the ship were ginger, cloves, saffron, and pepper.
The ginger plant was smuggled onto the Caribbean islands from Asia sometime in the 16th century, along with black pepper, cloves, and cinnamon, at the encouragement of the Spanish Crown, though only ginger thrived. It eventually displaced sugar to become the leading export crop on both Hispaniola and Puerto Rico by the end of the century, until the introduction of slave labour from Africa made sugar more economical to produce in the 17th century.
In 2023, world production of raw ginger was 4.9 million tonnes, led by India with 45% of the total, and Nigeria and China as secondary producers.
Ginger has the ability to grow in a wide variety of land types and areas, however is best produced when grown in a warm, humid environment, at an elevation between , and in well-drained soils at least 30 cm deep. A period of low rainfall prior to growing and well-distributed rainfall during growing are also essential for the ginger to thrive well in the soil.
Ginger produced in India is most often farmed through homestead farming, with work adaptively shared by available family and community members.
Once the seeds are properly treated, the farmland in which they are to be planted must be thoroughly dug or ploughed by the farmer to break up the soil. After the soil is sufficiently ploughed (at least 3–5 times), water channels are made apart to irrigate the crop.
The next step is planting the rhizome seed. In India, planting the irrigated ginger crop is usually done in the months between March and June as those months account for the beginning of the monsoon, or rainy season. Once the planting stage is done, farmers go on to mulch the crop to conserve moisture and check weed growth, as well as check surface run-off to conserve soil. Mulching is done by applying mulch (green leaves for example) to the plant beds directly after planting and again 45 and 90 days into growth. After mulching comes hilling, which is the stirring and breaking up of soil to check weed growth, break the firmness of the soil from rain, and conserve soil moisture. Farmers must ensure that their ginger crops are receiving supplemental irrigation if rainfall is low in their region. In India, farmers must irrigate their ginger crops every two weeks at the least between September and November (when the monsoon is over) to ensure maximum yield and high quality product.
The final farming stage for ginger is the harvesting stage. When the rhizome is planted for products such as vegetable, soda, and candy, harvesting should be done between four and five months of planting, whereas when the rhizome is planted for products such as dried ginger or ginger oil, harvesting must be done eight to ten months after planting.
Dry ginger is one of the most popular forms of ginger in commerce. Ginger rhizomes for dry ginger are harvested at full maturity (8–10 months). After soaking them in water, the outer skin is scraped off with a bamboo splinter or wooden knife by hand as it is too delicate a process to be done by machinery. The whole dried rhizomes are ground in the consuming centres. Fresh ginger does not need further processing after harvest, and it is harvested much younger.
States from which ginger is exported follow the marketing channels of vegetable marketing in India, and the steps are similar to those when transported domestically. However, instead of reaching a terminal market after the regional forwarding centres, the produce will reach an export market and then be sent off by vehicle, plane or boat to reach its final international destination, where it will arrive at a local retail market and finally reach the consumer once purchased.
Dry ginger is most popularly traded between Asian countries through a unique distribution system involving a network of small retail outlets. Fresh and preserved ginger are often sold directly to supermarket chains, and in some countries fresh ginger is seen exclusively in small shops unique to certain ethnic communities. India frequently exports its ginger and other vegetable produce to nearby Pakistan and Bangladesh, as well as "Saudi Arabia, the United Arab Emirates, Morocco, the United States, Yemen Republic, the United Kingdom, and Netherlands".
Though India is the largest ginger producer in the world, it fails to play the role of a large exporter and only accounts for about 1.17% of total ginger exports. Ginger farming in India is a costly and risky business, as farmers do not gain much money from exports and "more than 65% of the total cost incurred is toward labor and seed material purchase". The farm owner may benefit given that there are no losses in production or price decreases, which is not easily avoidable. Production of dry ginger proves to have a higher benefit-cost ratio, as well as ginger cultivated in intercropping systems rather than as a pure crop.
Ginger is a fragrant kitchen spice. Young ginger rhizomes are juicy and fleshy with a mild taste. They are often pickled in vinegar or sherry as a snack or cooked as an ingredient in many dishes. They can be steeped in boiling water to make ginger herb tea, to which honey may be added. Ginger can be made into candy or ginger wine.
In Indian cuisine, ginger is a key ingredient, especially in thicker gravies, as well as in many other dishes, both vegetarian and meat-based. Ginger has a role in traditional Ayurvedic medicine. It is an ingredient in traditional Indian drinks, both cold and hot, including spiced masala chai. Fresh ginger is one of the main spices used for making pulse and lentil curries and other vegetable preparations. Fresh ginger together with peeled garlic cloves is crushed or ground to form ginger garlic masala. Fresh, as well as dried, ginger is used to spice tea and coffee, especially in winter. In south India, "sambharam" is a summer yogurt drink made with ginger as a key ingredient, along with green chillies, salt and curry leaves. Ginger powder is used in food preparations intended primarily for pregnant or nursing women, the most popular one being katlu, which is a mixture of gum resin, ghee, nuts, and sugar. Ginger is also consumed in candied and pickled form. In Japan, ginger is pickled to make beni shōga and gari or grated and used raw on tofu or . It is made into a candy called shoga no Sugar Tsukemono. In the traditional Korean cuisine kimchi, ginger is either finely minced or just juiced to avoid the fibrous texture and added to the ingredients of the spicy paste just before the fermenting process.
In Myanmar, ginger is called gyin. It is widely used in cooking and as a main ingredient in traditional medicines. It is consumed as a salad dish called gyin-thot, which consists of shredded ginger preserved in oil, with a variety of nuts and seeds. In Thailand' where it is called ขิง khing, it is used to make a ginger garlic paste in cooking. In Indonesia, a beverage called wedang jahe is made from ginger and palm sugar. Indonesians also use ground ginger root, called jahe, as a common ingredient in local recipes. In Malaysia, ginger is called halia and used in many kinds of dishes, especially soups. Called luya in the Philippines, ginger is a common ingredient in local dishes and is brewed as a tea called salabat.
Fresh ginger can be substituted for ground ginger at a ratio of six to one, although the flavours of fresh and dried ginger are somewhat different. Powdered dry ginger root is typically used as a flavouring for recipes such as gingerbread, , crackers and cakes, ginger ale, and ginger beer. Candied or crystallized ginger, known in the UK as " stem ginger", is the root cooked in sugar until soft, and is a type of confectionery. Fresh ginger may be peeled before eating. For longer-term storage, the ginger can be placed in a plastic bag and refrigerated or frozen.
A native species of eastern North America, Asarum canadense, is also known as "Asarum", and its root has similar aromatic properties, but it is not related to true ginger. The plant contains aristolochic acid, a compound. The United States Food and Drug Administration warns that consumption of aristolochic acid-containing products is associated with "permanent kidney damage, sometimes resulting in kidney failure that has required kidney dialysis or kidney transplantation. In addition, some patients have developed certain types of cancers, most often occurring in the urinary tract."
Zingerone is produced from gingerols during drying, having lower pungency and a spicy-sweet aroma. Shogaols are more pungent, and are formed from gingerols during heating, storage or via acidity. Numerous , , dietary fiber, protein, , , and are other constituents. Fresh ginger also contains an enzyme zingibain which is a cysteine protease and has similar properties to rennet.
There is no clear evidence that taking ginger to treat nausea during pregnancy is safe. Ginger is not effective for treating dysmenorrhea. There is some evidence for it having an anti-inflammatory effect, but insufficient evidence for it affecting pain in osteoarthritis. There is no good evidence that ginger affects platelet aggregation and Coagulation.
A 2018 review found evidence that ginger could decrease body weight in obese subjects and increase HDL-cholesterol.
