Coleus barbatus, also known by the synonyms Plectranthus barbatus and incorrectly Coleus forskalaei (and other spellings of this epithet), is a tropical perennial plant related to the typical coleus species. It is known by the common name woolly plectranthus. It produces forskolin, an extract useful for pharmaceutical preparations and research in cell biology. [3]
The Brazilian name is boldo brasileiro (pronounced [ˈbowdubɾaziˈlejɾu] ), or boldo gaúcho, as opposed to the Chilean true boldo; boldo-da-terra (pronounced [ˈbowdudɐˈtɛʁɐ] ); boldo-de-jardim (pronounced [ˈbowdudʒiʒaʁˈdʒĩ] ); or tapete-de-Oxalá (pronounced [tɐˈpetʃidʒoʃaˈla] ; 'Oxalá's carpet', because of its velvety texture).
In the French Caribbean, it is called "doliprane" (from the brand name of a paracetamol-based drug) because of its uses as a painkiller in folk medicine.
It is a semi-succulent plant that grows as a subshrub to 1.5 m high by 1.5 m wide. The oppositely arranged leaves are relatively large with serrated leaf edges. Purple-blue flowers grow on upright racemose inflorescences that are up to 25 centimeters long. [4]
The distribution area extends from tropical Africa across the Arabian Peninsula to parts of South Asia and East Asia. It is native to Burundi, China South-Central, East Himalaya, Eritrea, Ethiopia, India, Kenya, Nepal, Oman, Rwanda, Saudi Arabia, Somalia, Sri Lanka, Sudan, Tanzania, Thailand, Uganda, Yemen and Zaïre.

Coleus barbatus was first described by Henry Cranke Andrews in 1810 as Plectranthus barbatus. [5] It was transferred to Coleus by Bentham in 1830. [6] [1] Although Coleus was previously sunk into Plectranthus, the original binomial was revived in a major study of the subtribe Plectranthinae in 2019. [2]
There has been some confusion over the synonyms of this species. Plectranthus forskaolaei was first described by Vahl in 1790. [7] Vahl's name is illegitimate, because he treats it as a synonym of the earlier described Ocimum hadienseForrsk. Vahl spelt the epithet as "Forskålaei", [7] referring to Pehr Forsskål, whose surname is also spelt "Forskål". [8] The International Code of Nomenclature for algae, fungi, and plants at Art. 60.7 specifies that "å" is to be replaced by "ao". [9]
Willdenow in 1800 referred to Vahl's name, but spelled the epithet "forskolaei". [10] (As of 31 July 2020 [update] , the International Plant Names Index had the spelling "forskalei". [11] ) It was probably this species that Briquet referred to when transferring a species to Coleus as "C. forskohlii(Willd.) Briq.", introducing yet another spelling of the epithet; however, Briquet did not explicitly refer to a basionym. Briquet regarded "Coleus forskohlii" as synonymous with what he called "C. barbatusBenth.", [12] although Vahl had originally given a different synonymy. Paton et al. (2019) state that the epithets "forskalaei" or "forskohlii" are incorrectly applied to this species, instead treating binomials with these epithets as synonyms of Coleus hadiensis , in accordance with Vahl's original use. [2]
Herbal teas made from Coleus barbatus contain rosmarinic acid and also flavonoid glucuronides and diterpenoids. [13] [14]
Forskolin, which derives its name from the incorrect binomial name of this plant, Coleus forskohlii, has been isolated from the roots. [3] [15]
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.
Genus is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Coleus amboinicus, synonym Plectranthus amboinicus, is a semi-succulent perennial plant in the family Lamiaceae with a pungent oregano-like flavor and odor. Coleus amboinicus is considered to be native to parts of Africa, the Arabian Peninsula, and India, although it is widely cultivated and naturalized elsewhere in the tropics where it is used as a spice and ornamental plant. Common names in English include Indian borage, country borage, French thyme, Indian mint, Mexican mint, Cuban oregano, broad leaf thyme, soup mint, Spanish thyme. The species epithet, amboinicus refers to Ambon Island, in Indonesia, where it was apparently encountered and described by João de Loureiro (1717–1791).
Species Plantarum is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genera. It is the first work to consistently apply binomial names and was the starting point for the naming of plants.
Plectranthus is a genus of about 85 species of flowering plants from the sage family, Lamiaceae, found mostly in southern and tropical Africa and Madagascar. Common names include spur-flower. Plectranthus species are herbaceous perennial plants, rarely annuals or soft-wooded shrubs, sometimes succulent; sometimes with a tuberous base.
Coleus argentatus, synonym Plectranthus argentatus, common name silver spurflower, is a species of flowering plant in the mint family. It is native to rock outcrops and rainforest in the border region of Queensland and New South Wales, Australia. Growing to 1 m (3 ft) tall and broad, it is a spreading deciduous shrub. The hairy leaves are ovate to broad-ovate, 5–11.5 cm long, 3–5.5 cm wide with crenate margins. The hairs give the plant an overall sage green to silvery colour. The flowers are borne on terminal racemes up to 30 cm (12 in) long, and are bluish white.
Coleus scutellarioides, commonly known as coleus, is a species of flowering plant in the family Lamiaceae, native to southeast Asia through to Australia. Typically growing to 60–75 cm (24–30 in) tall and wide, it is a bushy, woody-based evergreen perennial, widely grown for the highly decorative variegated leaves found in cultivated varieties. Another common name is painted nettle, reflecting its relationship to deadnettles, which are in the same family. The synonyms Coleus blumei, Plectranthus scutellarioides and Solenostemon scutellarioides are also widely used for this species.
Coleus socotranus, synonym Plectranthus socotranus, is a species of flowering plant in the family Lamiaceae.
Salvia forskaehlei, synonym Salvia forskohlei, is a flowering plant in the family Lamiaceae native to Bulgaria and Turkey. The spelling Salvia forsskaolei is also used. It is a herbaceous perennial plant. It grows up to 6,000 ft elevation in broad-leaved and coniferous forests, meadows, and on steep banks. It was named after Finnish explorer and naturalist Peter Forsskål, a student of Carl Linnaeus who collected plants in southwest Arabia in the 18th century.
Coleus maculosus subsp. edulis, synonym Plectranthus edulis, the Ethiopian potato, known as wolayta dinich or oromo dinich in Amharic, is a species of perennial plant in the family Lamiaceae. Indigenous to Ethiopia, it is grown for its edible tubers, which are cooked before they are eaten.

Coleus neochilus, synonym Plectranthus neochilus, which is colloquially known as lobster bush, fly bush or mosquito bush, is a perennial ground cover with highly fragrant, partially scalloped, ovate leaves and purple blue inflorescent spikes.
Nepetoideae is a subfamily of plants in the family Lamiaceae.
Equilabium is a genus of flowering plants in the family Lamiaceae. It was split off from the genus Plectranthus in 2018 as the result of a molecular phylogenetic study. Most species are native to Africa, with two found in the Indian subcontinent.
