Dominican tea culture combines many customs adapted from various colonial and immigrant cultures that have mingled in Dominica. "Bush teas", made from local herbal plants and often taken for medicinal purposes, are a traditional part of Dominica's culture.
Dominica's tropical rainforest climate makes it suitable for cultivating many types of plant that may be used to make teas. The word "tea" has a broader meaning in Dominica than in most other parts of the English-speaking world. In Dominica, the word is used for many beverages other than the traditional Camellia sinensis imported from Asia. Imported tea from Asia is called "green tea". Dominicans also consume "Cocoa Tea", made of cocoa beans, and several types of "bush tea". Bush teas are brewed from herbs, in some cases using plant roots, bark or flowers, which are traditionally held to have medicinal properties. Dominicans also distinguish between "hot teas" and "cooling teas". [1]
"Tea" is often used instead of "breakfast" for the first meal of the day. This usage has its origins in the colonial era, when plantation workers would have "tea" at sunrise before going to work. The second "tea" of the day took place in mid-morning. This is different from British culture, where "tea" often refers to a light meal with a cup of Assam tea in the late afternoon. [1]
Cocoa is a staple crop in Dominica that most farmers traditionally harvested, and that is common in Caribbean markets. Cocoa tea is made by chopping a cocoa stick or ball into small pieces, or shredding the cocoa on a grater. It is mixed with water, condensed milk, cinnamon, leaves from a Christmas bush or bay leaves, grated nutmeg and sugar. Cocoa tea is served hot, often accompanied by a light snack such as banana fritters. [2] Cocoa tea is similar to hot chocolate. [3]
Hibiscus tea is popular in Dominica, as in other Caribbean and Latin American cultures. Hibiscus plants are native to the tropics, and have long been associated with health benefits in traditional medicine. Hibiscus tea may be served either hot or as an iced tea. [4] Some studies indicate that hibiscus tea lowers blood pressure in adults with mild hypertension or prehypertension. [5] [6]
Bush teas are usually drunk for medicinal purposes or to maintain health. [3] Many common plants in Dominica are used in these teas. Tea from the Common Guava leaf is used for diarrhea, and tea from the orange leaf is taken to stop vomiting. Caribbean Albizia bark (Albizia niopoides) gives a tea that soothes scorpion stings. Other bush teas are used to treat vitamin deficiencies, digestive ailments, or parasitic infections. Some plants believed to have medicinal properties are located at the Dominica Botanic Gardens. These include varieties that have been used in traditional medicinal teas in Dominica, and plants used in traditional medicine in other Caribbean islands or other parts of the world. [7]
Medicinal teas in Dominica can be traced to the original indigenous Carib inhabitants and to the African slaves who were brought to the islands. The Caribs traditionally made a tea from the leaves of the periwinkle plant (Catharanthus roseus) for use as a treatment for diabetes. [7] Pharmacological companies today extract several medicinal alkaloids from periwinkle sap. The alkaloids derived from this plant include the anti-cancer agents vinblastine and vincristine. [8] Other extracts from periwinkle help lower blood sugar in diabetics and are the basis for powerful tranquilizers. [7] [9] The powerful qualities of this plant were known to other cultures; it is known by the name Violette de Sorcier (Sorcerer's Violet) in France. [10] [11]
As with many indigenous traditional medicines, the active ingredients of the plants used to make bush teas are not well understood. At incorrect doses, or otherwise misused, teas made from these plants are toxic and may be deadly. Worldwide, researchers are investigating indigenous herbal medicines in an effort to identify active ingredients and traditional preparations, which may have uses for modern medicine. [7]
Herbal teas—less commonly called tisanes —are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. The term "herbal tea" is often used in contrast to true teas, which are prepared from the cured leaves of the tea plant, Camellia sinensis. Unlike coffee and true teas, most tisanes do not contain caffeine naturally.
The Kalinago, also known as the Island Caribs or simply Caribs, are an indigenous people of the Lesser Antilles in the Caribbean. They may have been related to the Mainland Caribs (Kalina) of South America, but they spoke an unrelated language known as Island Carib. They also spoke a pidgin language associated with the Mainland Caribs.
Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.
The Chelsea Physic Garden was established as the Apothecaries' Garden in London, England, in 1673 by the Worshipful Society of Apothecaries to grow plants to be used as medicines. This four acre physic garden, the term here referring to the science of healing, is among the oldest botanical gardens in Britain, after the University of Oxford Botanic Garden. Its rock garden is the oldest in Europe devoted to alpine plants and Mediterranean plants. The largest fruiting olive tree in Britain is there, protected by the garden's heat-trapping high brick walls, along with what is doubtless the world's northernmost grapefruit growing outdoors. Jealously guarded during the tenure of the Worshipful Society of Apothecaries, the Garden became in 1983 a registered charity and was opened to the general public for the first time.
Traditional medicine comprises medical aspects of traditional knowledge that developed over generations within various societies before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is contrasted with scientific medicine.
Catharanthus is a genus of flowering plants in the family Apocynaceae. Like the genus Vinca, they are known commonly as periwinkles. There are eight known species. Seven are endemic to Madagascar, though one, C. roseus, is widely naturalized around the world. The eighth species, C. pusillus, is native to India and Sri Lanka. The name Catharanthus comes from the Greek for "pure flower".
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesise hundreds of chemical compounds for functions including defence against insects, fungi, diseases, and herbivorous mammals. Numerous phytochemicals with potential or established biological activity have been identified. However, since a single plant contains widely diverse phytochemicals, the effects of using a whole plant as medicine are uncertain. Further, the phytochemical content and pharmacological actions, if any, of many plants having medicinal potential remain unassessed by rigorous scientific research to define efficacy and safety.
Vincristine, also known as leurocristine and marketed under the brand name Oncovin among others, is a chemotherapy medication used to treat a number of types of cancer. This includes acute lymphocytic leukemia, acute myeloid leukemia, Hodgkin's disease, neuroblastoma, and small cell lung cancer among others. It is given intravenously.
Vinca is a genus of flowering plants in the family Apocynaceae, native to Europe, northwest Africa and southwest Asia. The English name periwinkle is shared with the related genus Catharanthus.
Roselle is a species of Hibiscus probably native to West and East Africa and South-East Asia including Northeastern India. It is used for the production of bast fibre and as an infusion, in which it may be known as carcade.
Vinorelbine (NVB), sold under the brand name Navelbine among others, is a chemotherapy medication used to treat a number of types of cancer. This includes breast cancer and non-small cell lung cancer. It is given by injection into a vein or by mouth.
Vinblastine (VBL), sold under the brand name Velban among others, is a chemotherapy medication, typically used with other medications, to treat a number of types of cancer. This includes Hodgkin's lymphoma, non-small cell lung cancer, bladder cancer, brain cancer, melanoma, and testicular cancer. It is given by injection into a vein.
Catharanthus roseus, commonly known as bright eyes, Cape periwinkle, graveyard plant, Madagascar periwinkle, old maid, pink periwinkle, rose periwinkle, is a species of flowering plant in the family Apocynaceae. It is native and endemic to Madagascar, but grown elsewhere as an ornamental and medicinal plant, a source of the drugs vincristine and vinblastine, used to treat cancer. It was formerly included in the genus Vinca as Vinca rosea.
Vinca alkaloids are a set of anti-mitotic and anti-microtubule alkaloid agents originally derived from the periwinkle plant Catharanthus roseus and other vinca plants. They block beta-tubulin polymerization in a dividing cell.
Hibiscus tea is an herbal tea made as an infusion from crimson or deep magenta-colored calyces (sepals) of the roselle flower. It is consumed both hot and cold. It has a tart, cranberry-like flavor.
Protocatechuic acid (PCA) is a dihydroxybenzoic acid, a type of phenolic acid. It is a major metabolite of antioxidant polyphenols found in green tea. It has mixed effects on normal and cancer cells in in vitro and in vivo studies.
Dominica cuisine is the cuisine of the island nation of Dominica. The cuisine is rooted in creole techniques with local produce flavored by spices found on the island.
Mexican tea culture is known for its traditional herbal teas which are reputed to have medicinal properties. In recent decades, imported tea beverages have also become popular in Mexico. Mexican tea recipes have grown in popularity beyond Mexico as well.
Afro-Dominicans are Dominicans of African descent and the majority of the Commonwealth of Dominica's population.
Catharanthus trichophyllus is a species of flowering plant in the family Apocynaceae. It is endemic to Madagascar, where it is most common in northern regions.
