Oregano is a flowering plant in the mint family (Lamiaceae). It is native to temperate Western and Southwestern Eurasia and the Mediterranean region.
Thyme is any member of the genus Thymus of aromatic perennial evergreen herbs in the mint family Lamiaceae. Thymes are relatives of the oregano genus Origanum. They have culinary, medicinal, and ornamental uses, and the species most commonly cultivated and used for culinary purposes is Thymus vulgaris.
Plectranthus amboinicus, once identified as Coleus amboinicus, is a semi-succulent perennial plant in the family Lamiaceae with a pungent oregano-like flavor and odor. The origin of Plectranthus amboinicus is unknown, but it may be native to Africa, and possibly India. Plectranthus amboinicus is widely cultivated and naturalized elsewhere in the tropics where it is used as a traditional medicine, spice, and ornamental plant. Common names in English include Indian borage, country borage, Cuban oregano, French thyme, Indian mint, Mexican mint, soup mint, Spanish thyme. Plectranthus is the genus. The species name, amboinicus refers to Ambon Island, in Indonesia, where it was apparently encountered and described by João de Loureiro.
An antimicrobial is an agent that kills microorganisms or stops their growth. Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified according to their function. Agents that kill microbes are microbicidal, while those that merely inhibit their growth are called biostatic. The use of antimicrobial medicines to treat infection is known as antimicrobial chemotherapy, while the use of antimicrobial medicines to prevent infection is known as antimicrobial prophylaxis.
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants. Those studying phytochemistry strive to describe the structures of the large number of secondary metabolic compounds found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds. Plants synthesize phytochemicals for many reasons, including to protect themselves against insect attacks and plant diseases. Phytochemicals in food plants are often active in human biology, and in many cases have health benefits. The compounds found in plants are of many kinds, but most are in four major biochemical classes, the alkaloids, glycosides, polyphenols, and terpenes.
Monarda is a genus of flowering plants in the mint family, Lamiaceae. The genus is endemic to North America. Common names include bee balm, horsemint, oswego tea, and bergamot, the latter inspired by the fragrance of the leaves, which is reminiscent of bergamot orange. The genus was named for the Spanish botanist Nicolás Monardes, who wrote a book in 1574 describing plants of the New World.
Origanum dictamnus, known in Greek as δίκταμο or in Cretan dialect έρωντας, is a tender perennial plant that grows 20–30 cm high. It is a healing, therapeutic and aromatic plant that grows wild only on the mountainsides and gorges of the Greek island of Crete, Greece. The dittany of Crete is widely used for food flavouring and medicinal purposes, in addition to it featuring as an ornamental plant in gardens. This small, lanate shrub is easily recognised by the distinctive soft, woolly covering of white-grey hair on its stems and round green leaves, giving it a velvety texture. Tiny rose-pink flowers surrounded by brighter purple-pink bracts add an exuberant splash of colour to the plant in summer and autumn. The dittany is classified as vulnerable on the IUCN Red List of Threatened Plant Species 1997.
A chemotype is a chemically distinct entity in a plant or microorganism, with differences in the composition of the secondary metabolites. Minor genetic and epigenetic changes with little or no effect on morphology or anatomy may produce large changes in the chemical phenotype. Chemotypes are often defined by the most abundant chemical produced by that individual and the concept has been useful in work done by chemical ecologists and natural product chemists. With respect to plant biology, the term "chemotype" was first coined by Dr. Rolf Santesson and his son Johan in 1968, defined as, "...chemically characterized parts of a population of morphologically indistinguishable individuals."
Carvacrol, or cymophenol, C6H3(CH3)(OH)C3H7, is a monoterpenoid phenol. It has a characteristic pungent, warm odor of oregano.
Eucalyptol is a natural organic compound that is a colorless liquid. It is a cyclic ether and a monoterpenoid.
Caryophyllene, more formally (−)-β-caryophyllene, is a natural bicyclic sesquiterpene that is a constituent of many essential oils, especially clove oil, the oil from the stems and flowers of Syzygium aromaticum (cloves), the essential oil of Cannabis sativa, rosemary, and hops. It is usually found as a mixture with isocaryophyllene and α-humulene, a ring-opened isomer. Caryophyllene is notable for having a cyclobutane ring, as well as a trans-double bond in a 9-membered ring, both rarities in nature.
Thymus herba-barona is a species of thyme native to Corsica, Sardinia, and Majorca. It is also sometimes known by the common name caraway thyme, as it has a strong scent similar to caraway, for which it can be used as a substitute in any recipe. It can be used in cuisine or as an evergreen ground cover plant for the garden.
Thymus vulgaris is a species of flowering plant in the mint family Lamiaceae, native to southern Europe from the western Mediterranean to southern Italy. Growing to 15–30 cm (6–12 in) tall by 40 cm (16 in) wide, it is a bushy, woody-based evergreen subshrub with small, highly aromatic, grey-green leaves and clusters of purple or pink flowers in early summer.
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.
Monarda fistulosa, the wild bergamot or bee balm, is a wildflower in the mint family (Lamiaceae) widespread and abundant as a native plant in much of North America. This plant, with showy summer-blooming pink to lavender flowers, is often used as a honey plant, medicinal plant, and garden ornamental. The species is quite variable, and several subspecies or varieties have been recognized within it.
Thymus pannonicus, known by its common name Hungarian thyme or Eurasian thyme, is a perennial herbaceous plant, distributed in central and eastern Europe and Russia. It grows over open dry meadows, grasslands, and rocks.
Origanum onites, the Cretan oregano, Greek oregano, pot marjoram or Ellinikí rίgani in Greek, is a plant species in the genus Origanum found in Sicily, Greece and Turkey. It has similar flavors as oregano. Its essential oil can be distinguished from other species such as Greek oregano. It has antimicrobial activities.
2,5-Dimethoxy-p-cymene, or thymohydroquinone dimethyl ether, is a phytochemical found in the essential oils of plants within the family Asteraceae. These essential oils, which contain the compound as a major component of the oil, have antifungal, antibacterial, and insecticidal properties.
Thymus zygis is a type of flowering plant in the family Lamiaceae.
