Mimosa hostilis root bark mimosa is widely used in making of analog ayahuasca brews such as Juremahuasca or Mimohuasca. The primary active ingredient in this part of the plant is N,N-DMT and there is also a small amount of β-carbolines.

Product information


Mimosa tenuiflora, syn. Mimosa hostilis (Jurema, Tepezcohuite) is a perennial tree or shrub native to the northeastern region of Brazil and found as far north as southern Mexico (Oaxaca and coast of Chiapas). It is most often found in lower altitudes, but it can be found as high as 1000 m.

Effect of jurema

Dried Mimosa root bark has been recently shown to have a DMT (Dimethyltryptamine) content of about 1%. The stem bark has about 0.03% DMT. The bark is the part of the tree 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 root bark is consistently used without added MAOI.

This presents challenges to the pharmacological understanding of how DMT from the plant is rendered orally active as an entheogen. In this view, if MAOI is neither present in the plant nor added to the mixture, the enzyme MAO will break apart DMT in the human gut, preventing the active molecule from entering blood and brain.

The isolation of a new compound "Yuremamine" Mimosa tenuiflora as reported in 2005 represents a new class of phyto-indoles, which may explain an apparent oral activity of DMT in Jurema.

Nowadays M. hostilis is used primarily in combination with Peganum harmala to make anahuasca, which is a psychedelic infusion similar to ayahuasca. The effects can best be described as a physical and mental purge, combined with a 4 hour connection with the otherwise imperceptible. The purge is typically not as strong as with ayahuasca.

How to use jurema

For the purpose of anahuasca, jurema is usually powdered and made into a hot water infusion. Depending on the brewer's method, this infusion takes between 1 hour up to a day to make. Some people make two or more infusions from the same plant material and add them all together. Sometimes acidifiers like vinegar or lemonjuice are added to speed up the extraction. Typical boiling times are between 1.5 and 4 hours in total. The resulting liquid is boiled down to a small, drinkable size and drunk 15 to 60 minutes after taking a 3 to 4 gr P. harmala or 50 to 150 gr Banisteriopsis caapi preparation.

A psychoactive liquid can also be made from jurema alone. Place 25 to 35 gr (beginners between 10 and 20 gr) of the powdered rootbark in 125 to 175 ml of cold water for an hour and squeeze and stir the powder a couple of times. Strain and keep the liquid, and use the rootbark powder for a second run in the same fashion. The two liquids combined are ingested on an empty stomach.


When making anahuasca, be aware of the fact that you'll be using jurema in conjunction with an MAO-inhibiting plant, like P. harmala or B. caapi. MAO-inhibitors can be very dangerous when combined with certain foods or other psychoactives that are totally harmless when taken by themselves.
