Lobelia (/[invalid input: 'icon']l[invalid input: 'ɵ']ˈbiːliə/)[2] is a genus of flowering plant comprising 360–400 species, with a subcosmopolitan distribution primarily in tropical to warm temperate regions of the world, a few species extending into cooler temperate regions.[3] English names include Lobelia, Asthma Weed, Barfweed, Indian Tobacco, Heaveleaf, Sickbud, Pukeweed, Retchwort, Fool's Bane, and Vomitwort.
Some botanists place the genus and its relatives in the separate family Lobeliaceae, others as a subfamily Lobelioideae within the Campanulaceae. The Angiosperm Phylogeny Group did not make a firm decision in this, listing the genus under both families.
Lobelia is probably the base form from which many other lobelioid genera are derived; it is therefore highly paraphyletic and not a good genus.[not specific enough to verify][original research?] For example, the Hawaiian species (see Hawaiian lobelioids) originated from a single introduction to Hawaii 15 million years ago, probably from an Asian Lobelia in Lobelia subg. Tupa.[4] However, the group has not yet been studied adequately to rearrange the classification.[citation needed]
Lobelia species are used as food plants by the larvae of some Lepidoptera species including the Setaceous Hebrew Character.
The genus is named after the Belgian botanist Matthias de Lobel (1538–1616).[3]

Mexican spurred lobelias
About eleven species native to Mexico and Central America have spurs on the flowers. These spurred lobelias appear to form a monophyletic group. Most have been classified in the genera Heterotoma (or sometimes Calcaratolobelia). However, since their closest relatives, such as Lobelia anatina, are in Lobelia, Koopman and Ayers classify them in Lobelia.[8]
Partial list:
- Lobelia aurita (Heterotoma aurita). One of the most common understory plants in the Sierra de la Laguna pine-oak forests.[9]
- Lobelia calcarata (Heterotoma lobelioides[10] or Lobelia lobelioides[8])
- Lobelia cordifolia (Heterotoma cordifolia)[11]
- Lobelia flexuosa (Heterotoma flexuosa)[11]
- Lobelia mcvaughii[11]
- Lobelia volcanica (Heterotoma tenella)[11]

Cultivation and uses
Several species are cultivated as ornamental plants in gardens. These include Lobelia cardinalis (syn. Lobelia fulgens: Cardinal Flower or Indian Pink), Lobelia siphilitica (Blue Lobelia), and Lobelia erinus, as well as some hybrids. Note Lobelia x speciosa refers to a hybrid derived from Lobelia fulgens, L. cardinalis & L. siphilitica. The term "Fan hybrids" is also used. [12]
Lobelia erinus, a South African annual plant that includes many cultivated selections in a wide variety of colours. They are grown in beds, large pots, window boxes and in hanging baskets. The plants are most often grown away from sunny hot southern exposures (northern exposures in the southern hemisphere) in soils that are moisture retentive.
In the Victorian language of flowers, the lobelia symbolizes malevolence and ill will.
Medicinal use
Native Americans used lobelia to treat respiratory and muscle disorders, and as a purgative. The species used most commonly in modern herbalism is Lobelia inflata (Indian Tobacco).[13] However, there are adverse effects that limit the use of lobelia.[14]
Extracts of Lobelia inflata contain lobeline, which showed positive effects in the treatment of multidrug-resistant tumor cells.[15] Furthermore, lobeline can be modified to lobelane which decreased methamphetamine self-administration in rats.[16] It therefore opens a perspective in methamphetamine dependency treatment.[17]
Lobelia has been used as "asthmador" in Appalachian folk medicine [18]
Two species, Lobelia siphilitica and Lobelia cardinalis, were once considered a cure for syphilis.[19]
Herbalist Samuel Thomson popularized medicinal use of lobelia in the United States in the early 19th century, as well as other medicinal plants like goldenseal.[13]
One species, Lobelia chinensis (called bàn biān lián, 半边莲 in Chinese), is used as one of the fifty fundamental herbs in traditional Chinese medicine.
Several studies show that lobelia is ineffective in helping people to quit smoking.[20]
Adverse effects
Because of its similarity to nicotine, the internal use of lobelia may be dangerous to susceptible populations, including children, pregnant women,[21] and individuals with cardiac disease. Excessive use will cause nausea and vomiting.[22] It is not recommended for use by pregnant women and is best administered by a practitioner qualified in its use.
