Goji

The genus name Lycium was assigned by Linnaeus in 1753. The Latin name lycium is derived from the Greek word (''''), used by Pliny the Elder (23–79) and Pedanius Dioscorides (ca. 40–90) for a plant known as dyer's buckthorn, which was probably a Rhamnus species. The Greek word refers to the ancient region of Lycia () in Anatolia, where that plant grew. The common English name, wolfberry, has an unknown origin. It may have arisen from the mistaken assumption that the Latin name was derived from Greek (), meaning "wolf". In the English-speaking world, the name goji berry has been used since around 2000. In technical botanical nomenclature, Lycium barbarum is called matrimony vine, while Lycium chinense is Chinese desert-thorn. In the United States, various common names are used for Lycium species and varieties, such as desert-thorn, boxthorn, matrimony vine, and wolfberry. == Uses ==

Traditional East Asian cuisine Young wolfberry shoots and leaves are harvested commercially as a leaf vegetable. The berries are used in dishes as either a garnish or a source of sweetness. Food dehydration) '' Since the early 21st century, the dried fruit, occasionally compared to raisins, has been marketed as a health food, with unsupported health claims about its benefits. In the wake of those claims, dried and fresh goji berries were included in many snack foods and food supplements, such as granola bars. There are products of whole and ground wolfberry seeds and seed oil. ==Marketing controversies==

Exaggerated claims about the health benefits of goji berry and derived products have triggered strong reactions from government regulatory agencies. In 2019–2020, the U.S. Food and Drug Administration (FDA) placed two goji product distributors on notice with warning letters about unproven therapeutic benefits. The advertisers' statements were in violation of the United States Food, Drug and Cosmetic Act [21 USC/321 (g)(1)] because they "establish[ed] the product as a drug intended for use in the cure, mitigation, treatment, or prevention of disease" when goji ingredients have had no such scientific evaluation. Additionally stated by the FDA, the goji products are "not generally recognized as safe and effective for the referenced conditions" and therefore must be treated as a "new drug" under Section 21(p) of the Act. In the interview, Earl Mindell (then working for direct-marketing company FreeLife International, Inc.) falsely claimed the Memorial Sloan-Kettering Cancer Center in New York had completed clinical studies showing that use of wolfberry juice would prevent 75% of human breast cancer cases. The booklet contained false and unverified claims. A settlement agreement was reached on 28 April 2010, where FreeLife took steps to ensure that its goji products were not marketed as "unheated" or "raw", and made a contribution to an educational organization. As with many other novel "health" foods and supplements, the lack of clinical evidence and poor quality control in the manufacture of consumer products prevent goji from being clinically recommended or applied. ==Composition and research==

Because of the numerous effects claimed by traditional medicine, there has been considerable basic research to investigate the biological properties of the fruit phytochemicals. The composition of the fruits, seeds, roots, and other constituents has been analyzed, and extracts are under study. Constituents include carotenoids, polysaccharides (comprising 30% of the pulp), vitamins, fatty acids, and peptidoglycans. ==Safety==

Interaction with drugs In vitro testing suggests that unidentified wolfberry phytochemicals in goji tea may inhibit metabolism of medications, such as those processed by the cytochrome P450 liver enzymes, including such drugs as warfarin. Agriculture in the Tibetan Plateau (where many "Himalayan" or "Tibetan"-branded berries supposedly originate) conventionally uses fertilizers and pesticides, making organic claims for berries originating there dubious. Since the early 21st century, high levels of insecticide residues (including fenvalerate, cypermethrin, and acetamiprid) and fungicide residues (such as triadimenol and isoprothiolane), have been detected by the United States Food and Drug Administration in some imported wolfberries and wolfberry products of Chinese origin, leading to the seizure of these products. Pest control Use of botanical pesticides (particularly eucalyptus oil), surfactant adjuvants, and aphid parasitoids are employed to control aphids and powdery mildew on goji crops. == Cultivation and commercialization==

Wolfberries are most often sold in dried form. When ripe, the oblong, red berries are tender and must be picked or shaken from the vine into trays to avoid spoiling. The fruits are preserved by drying them in full sun on open trays or by mechanical dehydration, employing a progressively increasing series of heat exposure over 48 hours. Some 61% of commercially produced wolfberries in China comes from L. barbarum plantations in the Ningxia region, mainly in Zhongning County. Goji cultivation also occurs in Gansu, Qinghai Province, and the Haixi Mongol and Tibetan Autonomous Prefecture. The main berry products for export are manufactured beverages, juice concentrate, dried berries, snacks, and freeze-dried juice powder and berries. United Kingdom Lycium barbarum had been introduced in the United Kingdom in the 1730s by The Duke of Argyll, but the plant was mostly used for hedges and decorative gardening. The UK Food Standards Agency (FSA) had initially placed goji berry in the Novel Foods list. That classification would have required authorisation from the European Council and Parliament for marketing. However, on 18 June 2007, the FSA concluded that there was a significant history of consumption of the fruit before 1997, indicating its safety, and thus removed it from the list. Canada and United States In the first decade of the 21st century, farmers in Canada and the United States began cultivating goji on a commercial scale to meet potential markets for fresh berries, juice, and processed products. Australia Australia imports most of its goji berries from China, due to how expensive the Australian labour force is in comparison with the countries that have the largest share of the current market. == See also ==
