Dorstenia
''Dorstenia'' is a genus within the mulberry family, Moraceae. Depending on the author, there are said to be 100 to 170 species within this genus, second only in number to the genus ''Ficus'' within Moraceae. ''Dorstenia'' species are mainly known for their unusual inflorescences and growth habits. ''Dorstenia'' is named in honor of the German physician and botanist Theodor Dorsten (1492–1552).Genaust, Helmut (1976). ''Etymologisches Wörterbuch der botanischen Pflanzennamen'' The type species is ''Dorstenia contrajerva''. Growth habit ''Dorstenia'' is unique in the family Moraceae because of the extremely diverse growth habits and forms of its species. While the majority of Moraceae are woody perennials, ''Dorstenia'' species are predominantly herbaceous, succulent, or suffrutescent perennials. Only 10% exhibit the typical woody habit of the Moraceae. The spectrum of the genus ''Dorstenia'' ranges from small annuals to perennial herbaceous plants with and without rhizomes ...

Dorstenia Contrajerva
''Dorstenia contrajerva'' is a plant species in the family Moraceae. It is native to Northern South America and Central America, and is cultivated elsewhere. The species name "contrajerva" is the Latinized form of the plant's Spanish name, "contrahierba," a name for plants used for treating poisoning and venomous bites and stings, and for which its rootstocks are used in folk medicine (as contrayerva). It is the type species of the Dorstenia genus and was first described by Carl Linnaeus in 1753. Description ''Dorstenia contrajerva'' is a small evergreen perennial plant with a creeping rhizome from which emerges a rosette of leaves with long petioles. Leaves are variably shaped, with plants with lobed and unlobed leaves co-occurring in the same populations. Leaves are up to 20 cm long on petioles up to 25 cm long. When damaged the plant exudes a white latex. Tiny male and female flowers are distributed intermixed on a discoid receptacle of convoluted shape. The frui ...

Contrayerva
Contrayerva, or contrajerva, is the medicinal rhizome of various tropical Central American and South American species of ''Dorstenia'' in the family Moraceae, mainly ''Dorstenia contrajerva'' and the closely related '' Dorstenia drakena'' but also ''Dorstenia brasiliensis''. The word ''contrayerva'' means “counter herb” in Spanish. It was given this name since a 16th-century description (see below) claimed that the leaves of a herb (''yerva'' = ''hierba'') were used by South American Indians to counter the deadly poisonous effect of the same herb (“contra yerva”) when used as an arrow poison. Seventeenth century herbalists and botanists identified this herb as the aromatic root that had been brought from Peru to England by Francis Drake, and claimed that it was an antidote against all kinds of poison. By the late 18th century contrayerva had lost its reputation as an antidote, but it continued to be listed in European and American pharmacopoeias and herbals until the 1920s a ...

Moraceae
The Moraceae — often called the mulberry family or fig family — are a family of flowering plants comprising about 38 genera and over 1100 species. Most are widespread in tropical and subtropical regions, less so in temperate climates; however, their distribution is cosmopolitan overall. The only synapomorphy within the Moraceae is presence of laticifers and milky sap in all parenchymatous tissues, but generally useful field characters include two carpels sometimes with one reduced, compound inconspicuous flowers, and compound fruits. The family includes well-known plants such as the fig, banyan, breadfruit, jackfruit, mulberry, and Osage orange. The 'flowers' of Moraceae are often pseudanthia (reduced inflorescences). Historical taxonomy Formerly included within the now defunct order Urticales, recent molecular studies have resulted in the family's placement within the Rosales in a clade called the urticalean rosids that also includes Ulmaceae, Celtidaceae, Cannabaceae, ...

Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, bu ...
