Agathosma betulina | |
Agathosma betulina (previously Barosma betulina) is a flowering plant in the family Rutaceae, native to the lower elevation mountains of western South Africa, where it occurs near streams in fynbos habitats.
It is an evergreen shrub growing to 2 m (6 ft 7 in) tall. The leaves are opposite, rounded, about 20 mm (0.79 in) long and broad, glossy, and fragrant. [1] The flowers are white or pale pink, with five petals; the fruit is a five-parted capsule which splits open to release the seeds.
It is known by the common name round leaf buchu. The very similar plant Agathosma crenulata (previously Barosma crenulata) is known as the oval leaf buchu, and has been used for the same purposes. The two are chemically distinct, however; for example, A. betulina contains quercetin-dimethyl ether-glucoside, while A. crenulata does not. [2]
Wild plants of this species are still plentiful but are being harvested faster than they can reproduce. The threat of their becoming scarce has led to efforts to cultivate them. The essential oils and extracts of the leaves are used as flavoring for teas, candy, and a liquor known as buchu brandy in South Africa. The two primary chemical constituents of the oils of A. betulina are isomenthone and diosphenol. The extract is said to taste like blackcurrant.
The plant has been used by the indigenous people of South Africa to as a folk remedy for various disorders, including urinary tract infections. [3] Dutch settlers in early times used Agathosma betulina commonly called buchu to make a brandy tincture. The tincture is still used today. [4] [5]
Herbal medicine is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from Artemisia annua, a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of plants used in 21st century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine commonly includes fungal and bee products, as well as minerals, shells and certain animal parts. Herbal medicine is also called phytomedicine or phytotherapy.
Vitex agnus-castus, also called vitex, chaste tree, chasteberry, Abraham's balm, lilac chastetree, or monk's pepper, is a native of the Mediterranean region. It is one of the few temperate-zone species of Vitex, which is on the whole a genus of tropical and sub-tropical flowering plants. Theophrastus mentioned the shrub several times, as agnos (άγνος) in Enquiry into Plants. It has been long believed to be an anaphrodisiac – leading to its name as chaste tree – but its effectiveness for such action remains unproven.
Pharmacognosy is the study of medicinal plants and other natural substances as sources of drugs. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical, and biological properties of drugs, drug substances, or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources".
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including defense and protection against insects, fungi, diseases, and herbivorous mammals.
Agathosma is a genus of about 140 species of flowering plants in the family Rutaceae, native to the southern part of Africa. Common names include Buchu, Boegoe, Bucco, Bookoo and Diosma. Buchu formally denotes two herbal species, prized for their fragrance and medicinal use despite their toxicity. In colloquial use however, the term is applied to a wider set of fragrant shrubs or substitutes.
Myrcene, or β-myrcene, is a monoterpene. A colorless oil, it occurs widely in essential oils. It is produced mainly semi-synthetically from Myrcia, from which it gets its name. It is an intermediate in the production of several fragrances. α-Myrcene is the name for the isomer 2-methyl-6-methylene-1,7-octadiene, which has not been found in nature.
Infusion is the process of extracting chemical compounds or flavors from plant material in a solvent such as water, oil or alcohol, by allowing the material to remain suspended in the solvent over time. An infusion is also the name for the resultant liquid. The process of infusion is distinct from both decoction—a method of extraction involving boiling the plant material—and percolation, in which water is passed through the material.
Eucalyptus oil is the generic name for distilled oil from the leaf of Eucalyptus, a genus of the plant family Myrtaceae native to Australia and cultivated worldwide. Eucalyptus oil has a history of wide application, as a pharmaceutical, antiseptic, repellent, flavouring, fragrance and industrial uses. The leaves of selected Eucalyptus species are steam distilled to extract eucalyptus oil.
Phellodendron amurense is a species of tree in the family Rutaceae, commonly called the Amur cork tree. It is a major source of huáng bò, one of the 50 fundamental herbs used in traditional Chinese medicine. The Ainu people used this plant, called shikerebe-ni, as a painkiller. It is known as hwangbyeok in Korean and (キハダ) kihada in Japanese.
Mugwort is a common name for several species of aromatic flowering plants in the genus Artemisia. In Europe, mugwort most often refers to the species Artemisia vulgaris, or common mugwort. In East Asia the species Artemisia argyi is often called "Chinese mugwort" in the context of traditional Chinese medicine, or àicǎo (艾草) in Mandarin. Artemisia princeps is a mugwort known in Korea as ssuk (쑥) and in Japan as yomogi (ヨモギ). While other species are sometimes referred to by more specific common names, they may be called simply "mugwort" in many contexts.
Agathosma crenulata is a flowering plant in the family Rutaceae, native to the lower elevation mountains of southwestern South Africa, where it occurs near streams in fynbos habitats. It is an evergreen shrub growing to 1.5-2.5 m tall. The leaves are opposite, oval, 15–35 mm long and 7–18 mm broad. The flowers are white or pale pink, with five petals; the fruit is a five-parted capsule which splits open to release the seeds.
Decoction is a method of extraction by boiling herbal or plant material to dissolve the chemicals of the material. It is the most common preparation method in various herbal-medicine systems. Decoction involves first drying the plant material; then mashing, slicing, or cutting the material to allow for maximum dissolution; and finally boiling in water to extract oils, volatile organic compounds and other various chemical substances. Occasionally, aqueous ethanol or glycerol may be used instead of water. Decoction can be used to make tisanes, tinctures and similar solutions. Decoctions and infusions may produce liquids with differing chemical properties, as the temperature or preparation difference may result in more oil-soluble chemicals in decoctions versus infusions. The process can also be applied to meats and vegetables to prepare bouillon or stock, though the term is typically only used to describe boiled plant extracts, usually for medicinal or scientific purposes.
Kaempferia galanga, commonly known as kencur, aromatic ginger, sand ginger, cutcherry, is a monocotyledonous plant in the ginger family, and one of four plants called galangal. It is found primarily in open areas in Indonesia, southern China, Taiwan, Cambodia, and India, but is also widely cultivated throughout Southeast Asia.
Empleurum unicapsulare or false buchu is a South African shrub of the family Rutaceae and occurs from the southwestern districts of the Cape Province to the Uitenhage area.
Agathosma serratifolia, known as longleaf buchu or long buchu, is an erect, South African shrub, belonging to the citrus family Rutaceae. It is one of about 135 species mainly occurring in the south-western Cape Province. There, it is found on mountain slopes, wooded ravines, and valleys. The leaves are simple, ovoid, slightly serrated, and 0.5-3.5cm long. In April and May, the plant produces 5-petalled flowers. 'Agathosma' = 'good smell', 'serratifolia' = 'serrate leaved'.
Boegoe is a word of Khoikhoi origin, which may refer to a number of South African plants, fungi or a mineral, that were used in traditional preparations. Most Boegoe plants are typified by a strong aromatic odour due to volatile oils released by glands in the leaves. The name primarily denotes those plant species of which the stems, powdered leaves or volatile oils are employed in herbalism.
Agathosma gonaquensis is a species of plant in the family Rutaceae. Its habitat is restricted to a tiny area of the Eastern Cape, South Africa. According to the South African National Biodiversity Institute, it is critically endangered.
Zanthoxylum rhoifolium is a species of tree in the family Rutaceae known by the common names mamica de cadela, tambataru, and prickly ash. It is native to South America. It is a common tree on the Cerrado.
Diosma haelkraalensis, or Hagelkraal's diosma, is a rare species of plant from South Africa.
