Mimosa tenuiflora

The fern-like branches have leaves that are Mimosa like, finely pinnate, growing to long. Each compound leaf contains 15–33 pairs of bright green leaflets long. The tree itself grows up to tall In the Southern Hemisphere it blooms primarily from September to January. The fruit is brittle and averages long. Each pod contains 4–6 seeds that are oval, flat, light brown and in diameter. There are about 145 seeds/. In the Southern Hemisphere, the fruit ripens from February to April. The tree's bark is dark brown to gray. It splits lengthwise and the inside is reddish brown. The tree's wood is dark reddish brown with a yellow center. It is very dense, durable and strong, having a density of about . Mimosa tenuiflora does very well after a forest fire, or other major ecological disturbance.{{cite journal |author1=Ivonete Alves Bakke |author2=Olaf Andreas Bakke |author3=Alberício Pereira Andrade |author4=Ignacio Hernan Salcedo |date=Mar 2007 |title=Forage yield and quality of a dense thorny and thornless "jurema-preta" stand |journal=Pesquisa Agropecuária Brasileira |volume=42 |issue=3 |pages=341–347 |doi=10.1590/S0100-204X2007000300006 |issn=0100-204X == Medicinal uses ==

A tea made of the leaves and stem has been used to treat tooth pain. For cases of cough and bronchitis, a water extract (decoction) of Mimosa tenuiflora is drunk. A handful of bark in one liter of water is used by itself or in a syrup. Aqueous extracts of Mimosa are widely used for wound healing and burns in Central and South America. Consequently, the products of the plant (generally grouped under the term "Tepezcohuite") have become a popular and easily produced cosmetic ingredient in commercial skincare products. == Other uses ==

. The tree is an acceptable source of forage or fodder for animals, providing vital protein and other nutrients. The tree is an important source of forage for bees, especially during the dry season and in the beginning of the wet season. Like most plants in the family Fabaceae, Mimosa tenuiflora fertilizes the soil via nitrogen fixing bacteria. The tree is useful in fighting soil erosion and for reforestation. Mimosa tenuiflora is a very good source of fuel wood and works very well for making posts,), which protects it from rot. Due to its high tannin content, the bark of the tree is widely used as a natural dye and in leather production. It is used to make bridges, buildings, fences, furniture and wheels. It is an excellent source of charcoal and at least one study has been done to see why this is the case. The healing properties of the tree make it useful in treating domestic animals. A solution of the leaves or bark can also be used for washing animals in the prevention of parasites. Because the tree keeps most of its leaves during the dry season, it is an important source of shade for animals and plants during that time. ==Chemistry==

The bark is known to be rich in tannins, saponins, alkaloids, lipids, phytosterols, glucosides, xylose, rhamnose, arabinose, lupeol, methoxychalcones, and kukulkanins. Additionally, Mimosa tenuiflora contains labdane diterpenoids. == Psychedelic uses ==

Mimosa tenuiflora is an entheogen used by the Jurema Cult (O Culto da Jurema) in northeastern Brazil. Dried Mexican Mimosa tenuiflora root bark has been shown to have a dimethyltryptamine (DMT) content of about 1-1.7%. The parts of the tree are traditionally used in northeastern Brazil in a psychoactive decoction also called Jurema or Yurema. Analogously, the traditional Western Amazonian sacrament Ayahuasca is brewed from indigenous ayahuasca vines. However, to date no β-carbolines such as harmala alkaloids have been detected in Mimosa tenuiflora decoctions, yet the Jurema is used in combination with several plants. This presents challenges to the pharmacological understanding of how DMT from the plant is rendered orally active as an entheogen, because the psychoactivity of ingested DMT requires the presence of a monoamine oxidase inhibitor (MAOI), such as a β-carboline. If an MAOI is neither present in the plant nor added to the mixture, the enzyme monoamine oxidase (MAO) will metabolize DMT in the human gut, preventing the active molecule from entering the blood and brain. The plant is also used in clandestine manufacture of crystalline DMT. In this form, it is psychoactive by itself when vaporized and inhaled. The isolation of the chemical compound yuremamine from Mimosa tenuiflora as reported in 2005 represents a new class of phytoindoles, which may explain an apparent oral activity of DMT in Jurema. ==Cultivation==

For outside planting, USDA Zone 9 or higher is recommended. In nature, Mimosa tenuiflora "[...] fruits and seeds are disseminated by the wind in a radius of from the mother plant; rain carries them from slopes to lower plains and human activities contribute to their dissemination." Germination takes about 2–4 weeks. It is also possible to propagate Mimosa tenuiflora via cuttings. Trimming adult Mimosa tenuiflora during the rainy season is not recommended as it can kill them. ==Legal status==

United Nations Internationally, mescaline, DMT, and psilocin, are Schedule I drugs under the Convention on Psychotropic Substances. The Commentary on the Convention on Psychotropic Substances notes, however, that the plants containing them are not subject to international control: "The cultivation of plants from which psychotropic substances are obtained is not controlled by the Vienna Convention... Neither the crown (fruit, mescal button) of the Peyote cactus nor the roots of the plant Mimosa hostilis nor Psilocybe mushrooms themselves are included in Schedule 1, but only their respective principals, mescaline, DMT, and psilocin." ==See also==
