Sideritis, also known as ironwort, [1] mountain tea, Greek tea and shepherd's tea, is a genus of flowering plants known for their use as herbal medicine, commonly as a herbal tea. They are abundant in Mediterranean regions, the Balkans, the Iberian Peninsula and Macaronesia, but can also be found in Central Europe and temperate Asia. [2] [3] [4] [5]
In Greek, "sideritis" (Gr: σιδηρίτις) can be literally translated as "he who is made of iron". [6] The plant was known to ancient Greeks, specifically Pedanius Dioscorides and Theophrastus. [7] Although Dioscorides describes three species, only one (probably S. scordioides) is thought to belong to Sideritis. In ancient times "sideritis" was a generic reference for plants capable of healing wounds caused by iron weapons during battles. However, others hold that the name stems from the shape of the sepal, which resembles the tip of a spear. [3]
In 2002, molecular phylogenetic research found Sideritis and five other genera to be embedded in Stachys . [8] Further studies will be needed before Stachys, Sideritis, and their closest relatives can be revised.
Some schemes recognize and categorize up to 319 distinct species, subspecies, ecotypes, forms or cultivars, including: [9] [3]
Botanists have encountered difficulties in naming and classifying the varieties of Sideritis due to their subtle differences. One particularly confusing case is that of S. angustifolia Lagasca and S. tragoriganum Lagasca. [11]
The genus is composed of short (8–50 cm), xerophytic subshrubs or herbs, annual or perennial, that grow at high elevation (usually over 1000 m) with little or no soil, often on the surface of rocks. [2] [5] [12] [13]
It is pubescent, either villous or coated by a fine, woolly layer of microscopic intertwined hairs.
Sideritis inflorescence is verticillaster. [2] [3]
In Albania, Bulgaria, Greece, North Macedonia, and Turkey, Sideritis scardica, Sideritis clandestina , Sideritis syriaca, Sideritis perfoliata and various other species from the section Empedoclia are used as herbs either for the preparation of herbal teas, or for their aromatic properties in local cuisines. The herbal tea is commonly prepared by decoction, by boiling the stems, leaves and flowers in a pot of water, then often serving with honey and lemon.
Some plants in the genus have a history of use in traditional herbal medicine. [14] Research into the potential effects has taken place in universities in the Netherlands and in the southern Balkans where the plant is indigenous. [15]
Chemical constituents include diterpenoids and flavonoids. [16]
Sideritis raeseri is the most commonly cultivated Sideritis in Albania, Bulgaria, Greece, and North Macedonia, where advanced hybrids also exist. [5] Planting is recommended during two periods (October–November or February–March in the Northern hemisphere) and gathering in July, when in full bloom. The plant is typically dried before usage. [17]
The Lamiaceae or Labiatae are a family of flowering plants commonly known as the mint, deadnettle, or sage family. Many of the plants are aromatic in all parts and include widely used culinary herbs like basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla, as well as other medicinal herbs such as catnip, salvia, bee balm, wild dagga, and oriental motherwort. Some species are shrubs, trees, or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities, but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage. Others are grown for seed, such as Salvia hispanica (chia), or for their edible tubers, such as Plectranthus edulis, Plectranthus esculentus, Plectranthus rotundifolius, and Stachys affinis. Many are also grown ornamentally, notably coleus, Plectranthus, and many Salvia species and hybrids.
Oregano is a species of flowering plant in the mint family Lamiaceae. It was native to the Mediterranean region, but widely naturalised elsewhere in the temperate Northern Hemisphere.
Satureja is a genus of aromatic plants of the family Lamiaceae, related to rosemary and thyme. It is native to North Africa, southern and southeastern Europe, the Middle East, and Central Asia. A few New World species were formerly included in Satureja, but they have all been moved to other genera. Several species are cultivated as culinary herbs called savory, and they have become established in the wild in a few places.
Marrubium is a genus of flowering plants in the family Lamiaceae, native to temperate regions of Europe, North Africa, and Asia as far east as the Xinjiang region of western China. A few species are also naturalized in North and South America.
Bryonia is a genus of flowering plants in the gourd family. Bryony is its best-known common name. They are native to western Eurasia and adjacent regions, such as North Africa, the Canary Islands and South Asia.
Verbascum is a genus of over 450 species of flowering plants, common name mullein, in the figwort family Scrophulariaceae. They are native to Europe and Asia, with the highest species diversity in the Mediterranean.
Stachys is a genus of plants, one of the largest in the mint family Lamiaceae. Estimates of the number of species vary from about 300, to about 450. Stachys is in the subfamily Lamioideae and its type species is Stachys sylvatica. The precise extent of the genus and its relationship to other genera in the subfamily are poorly known.
Onopordum, or cottonthistle, is a genus of plants in the tribe Cardueae within the family Asteraceae. They are native to southern Europe, northern Africa, the Canary Islands, the Caucasus, and southwest and central Asia. They grow on disturbed land, roadsides, arable land and pastures.
Origanum is a genus of herbaceous perennial flowering plants and subshrubs in the family Lamiaceae. They are native to Europe, North Africa, and much of temperate Asia, where they are found in open or mountainous habitats. A few species also naturalized in scattered locations in North America and other regions.
Micromeria is a genus of flowering plants in the mint family, Lamiaceae, widespread across Europe, Asia, Africa, and North America, with a center of diversity in the Mediterranean region and the Canary Islands. It is sometimes placed within the genus Satureja. The name is derived from the Greek words μῑκρος (mīkros), meaning "small," and μερίς (meris), meaning "portion," referring to the leaves and flowers. Common names include savory and whitweed.
Iris attica, the Greek iris, is a plant species in the genus Iris, it is also in the subgenus Iris. It is a rhizomatous perennial, from the mountains of the Balkans in Europe, within the countries of Greece, former Yugoslavia, Turkey and North Macedonia. It has sage green or grey-green leaves, that are sickle-shaped, a stout short stem and 2 variable flowers, in shades from yellow to purple. They have a white or blue beard. It is often called Iris pumila subsp attica, but is classified in most sources, as a separate species, although it is closely related to Iris pumila, as a possible parent plant. It is cultivated as an ornamental plant in temperate regions.

It was first described in 1844.
